Este estudo experimental, realizado em preparação nervo frênico - diafragma de ratos e musculo biventer cervicis de pintainhos, teve por objetivo avaliar o efeito de diferentes anestésicos locais na transmissão neuromuscular e sua influência no bloqueio produzido pelo rocurônio. Foram avaliados os seguintes parâmetros: efeito dos anestésicos locais (lidocaína, bupivacaína racêmica, mistura em excesso enantiomérico de bupivacaína) e do rocurônio empregados isoladamente, na transmissão neuromuscular; o bloqueio produzido pelo rocurônio em preparações expostas aos anestésicos locais; a ação dos anestésicos locais na resposta contraturante da acetilcolina; seus efeitos nos potenciais de membrana e nos potenciais de placa terminal em miniatura. Os resultados foram expressos em médias e desvios padrão e analisados através dos testes t de Student, Mann-Whitney , Wilcoxon, Kruskall-Wallis e Anova com teste para comparação múltipla de Tukey. Adotou-se um nível de significância de 5% (p<0,05). Nas preparações nervo frênico -diafragma de rato, os anestésicos locais nas concentrações empregadas, não alteraram a amplitude das respostas musculares mas, potencializaram o efeito do rocurônio. Nas preparações biventer cervicis de pintainho os anestésicos locais promoveram diminuição na resposta contraturante da acetilcolina evidenciando um efeito pós-juncional. Não causaram alteração significativa nos potenciais de membrana, não demonstrando ação despolarizante na fibra muscular. A lidocaína promoveu um aumento inicial dos potenciais de placa terminal em miniatura (pptm) seguida de bloqueio e, a bupivacaína nas duas formulações causou diminuição na amplitude e na freqüência dos pptm, caracterizando um efeito pré-juncional. Os resultados obtidos neste estudo demonstram um sinergismo entre as drogas comprovado por efeitos pré e pós-juncionais / Abstract: Local anesthetics can interact with neuromuscular blockers and modify their pharmacokinetics and pharmacodynamics properties but this mechanism of interaction is very controversial. This experimental study performed in rat phrenic nerve diaphragm preparation and chick biventer cervicis muscle, had the objective to evaluate the effect of different local anesthetics in neuromuscular transmission and their influence in the block promoted by rocuronium. The parameters evaluated were that: the effect of local anesthetics (lidocaine, racemic bupivacaine, enantiomeric mixture of bupivacaine) and the rocuronium isolated in neuromuscular transmission; the block promoted by rocuronium in local anesthetics exposed preparations; the action of local anesthetics in contracture response of acetylcholine; their effects in membrane potentials and miniature end plate potentials. The results were expressed in average and standard deviation and analysed using T Student test, Mann-Whitney, Wilcoxon, Kruskall-Wallis and Anova with Tukey multiple comparative test. We adopted a level of significance of 5% (p<0,05). In rat phrenic nerv diaphragm preparation, local anesthetics in the concentrations employed did not caused alterations in the amplitude of muscle responses but potentialized the effect of rocuronium. In chick biventer cervicis preparations local anesthetics promoted a decrease in acetylcholine contracture response indicating a postjunctional effect. They did not cause significant alterations in membrane potential so they did not demonstrate depolarizing action in muscle fiber. Lidocaine promoted an initial increase in miniature end plate potentials (meps) followed by block and bupivacaine in the two formulations caused a decrease in the amplitude and frequency of meps, characterizing a prejunctional effect. The results obtained in this study demonstrate a synergism of the drugs confirmed by pre and postjunctional effects / Mestrado / Mestre em Farmacologia

O conhecimento dos mecanismos envolvidos na cicatrização de tecidos permite o cirurgião interferir no reparo de tecidos, prevenindo e prevendo complicações. Nosso objetivo foi avaliar os efeitos da lavagem peritoneal com bupivacaína na mortalidade e na cicatrização da anastomose em cólon descendente de ratos, em vigência de peritonite fecal ou não. Foram utilizados quarenta ratos machos Wistar, pesando entre 300-350g, distribuídos aleatoriamente em quatro grupos de dez animais cada. Foi realizada laparotomia e anastomose em cólon descendente seis horas após injeção intraperitoneal de solução fisiológica (SF) ou de fezes autólogas. Grupo 1: sem peritonite e lavagem com 3ml de SF; Grupo 2: Sem peritonite e lavagem com 8 mg/kg de bupivacaína a 0,5% (0,5ml) adicionado a 2,5ml de SF; Grupo 3: Peritonite e lavagem com 3ml de SF; Grupo 4: Peritonite e lavagem com 8 mg/kg de bupivacaína a 0,5% (0,5ml) adicionado a 2,5ml de SF. Os animais que evoluíram para óbito foram submetidos a necropsia. A eutanásia e o teste biomecânico de Energia Total de Ruptura (ETR) foram realizados no quinto dia de pós-operatório dos animais sobreviventes. O grupo 4 apresentou maior sobrevida quando comparado ao Grupo 3, sem significância estatística. O grupo 3 apresentou valores de ETR menores que os dos outros grupos, com significância estatística. Concluímos que a peritonite fecal aumentou a mortalidade e influenciou negativamente a anastomose em cólon descendente de ratos, diminuindo sua resistência intrínseca. A lavagem peritoneal com bupivacaína aumentou a resistência da anastomose em cólon descendente de ratos em vigência de peritonite fecal / Abstract: Ocurrence of intestinal anastomotic dehiscence is associated with significant increase of length of stay, morbidity, mortality, need of reoperations, healthcare costs and patient's distress. The knowledge on the mechanisms involved in tissue healing allows the surgeon to interfere on tissue healing, prevent and anticipate complications. Our purpose was to evaluate the effects of peritoneal lavage with bupivacaine on survival and initial healing of anastomosis on distal colon, performed under peritonitis or not. Forty male Wistar rats, weighing from 300 to 350g, were randomly divided in four groups and underwent laparotomy and anastomosis on the distal colon six hours after intraperitoneal injection of physiological solution (NS) or autologous fecal material. Group 1: No peritonitis and lavage with 3ml NS; Group 2: No peritonitis and lavage with 0.5ml of 0.5% bupivacaine (8mg/kg) added to 2.5 mL of NS; Group 3: Peritonitis and lavage with 3ml NS; Group 4: Peritonitis and lavage with 0.5ml of 0.5% bupivacaine (8mg/kg) added to 2.5 mL of NS. Necropsies were performed on the animals that died. Surviving animals were submitted to euthanasia and Total Energy of Rupture (TER) biomechanical test on the fifth post-operative day. Group 4 showed survival increase compared to Group 3, without statistical significance. Group 3 presented the smallest average TER, with statistical significance. We concluded that fecal peritonitis increased mortality and negatively influenced anastomosis performed on descending colon in rats, decreasing its resistance. Peritoneal lavage with bupivacaine increased the resistance of colic anastomosis performed on descending colon in rats under fecal peritonitis / Mestrado / Fisiopatologia Cirúrgica / Mestre em Ciências

O objetivo deste estudo foi preparar e realizar a caracterização inicial de formulação de articaína associada a lipossomas unilamelares (400nm) com gradiente de pH transmembranar, com sulfato de amônia como tampão interno sobre a viabilidade celular em culturas de queratinócitos humanos (HaCaT) e sobre a liberação de uma interleucina pró-inflamatória (IL-6), comparando com formulações de articaína livre. As células foram expostas às formulações de articaína nas concentrações 0,1%, 0,2% e 0,3% na forma de solução e em suspensão lipossomal (lipossomas unilamelares), além dos controles (soro fisiológico, suspensão lipossomal e meio de cultura). A avaliação da viabilidade celular (redução do MTT - espectrofotometria) foi realizada após 10 min e 4h e a quantificação da IL-6 (imunoensaio de ELISA) após 4h da exposição às formulações. Os resultados foram submetidos aos testes de Kruskal-Wallis com post-hoc de Dunn (viabilidade celular) e de Student-Newman-Keuls (IL-6) com significância de 5%. As vesículas lipossomais mantiveram-se integras após a encapsulação de articaína, apresentando 18,95% de eficiência de encapsulação. A polidispersão dos lipossomas sem anestésico foi de 0,2 ± 0,0, enquanto a dos liposomas contendo articaína variou de 0,56 ± 0,03 a 0,66 ± 0,10. O potencial Zeta variou de -10,5 ± 0,9 a -21,2 ± 0,9 mV. O tamanho das vesículas variou de 622 ± 71,5 a 796 ± 111,95 nm. A viabilidade celular foi diminuída após 10 min de exposição às formulações lipossomais (com e sem articaína) em relação aos demais tratamentos (p<0,05); as formulações lipossomais não diferiram entre si (p>0,05). Não houve diferenças entre os demais tratamentos (p>0,05), os quais não alteraram a viabilidade nesse tempo de exposição. Após exposição por 4h houve diminuição na viabilidade em todas as formulações lipossomais e nas formulações de articaína livre 0,2% e 0,3% (p<0,05), à exceção dos grupos controle e articaína 0,1% (p>0,05). A liberação de IL-6 não foi afetada pelas formulações lipossomais (p>0,05); a articaína livre em todas as concentrações testadas aumentou a liberação de IL-6, tanto em relação ao controle, quanto às formulações lipossomais com a mesma concentração de articaína (p<0,05). Conclui-se que a utilização de lipossomas com gradiente de pH transmembranar aumentou a encapsulação de articaína, entretanto, apresentou toxicidade intrínseca no modelo avaliado / Abstract: Articaine is not encapsulated in significant proportion in liposomes without transmembrane pH gradient. The aim of this study was to perform the initial characterization of a formulation of articaine in unilamelar liposome with transmembranarpH gradient and to observe its effects on human keratinocytes (HaCaT) regarding cellular viability and liberation of interleukin 6 (IL-6) in comparison to plain articaine. HaCaT cells were exposed to plain articaine solutions and liposomal suspensions (0.1%, 0.2% and 0.3% articaine concentrations) and to the controls (saline, liposomal suspension and culture medium). Cell viability (MTT reduction - spectrophotometry) was evaluated at 10 min and 4h after exposure to the treatments; IL-6 was determined after 4 h of cell treatments. Cell viability results were submitted to Kruskal-Wallis test, followed by Dunn post-hoc test; IL-6 results were analyzed by Kruskal-Wallis and Student-Newman-Keuls tests. Significance was set at 5%. Liposome vesicles remained intact after articaine loading and presented encapsulation efficiency of 18.95%. Liposome without anesthetic presented polydispersity index of 0.2 ± 0.0, while liposomes with articaine showed values of 0.56 ± 0.03 to 0.66 ± 0.10. Zeta potentials varied from -10.5 ±0.9 to -21.2 ± 0.9 mV and vesicle sizes from 622 ± 71.5 to 796 ± 111.95 nm. Cell viability decreased after 10 min exposure to the liposomal formulations (with and without articaine) in relation to the other treatments (p<0.05); liposomal formulations did not differ from each other (p>0.05). No differences were found among the other treatments (p>0.05), which did not interfere in cell viability after this exposure time. After 4h exposure cell viability was diminished by all liposomal formulations and by 0.2% and 0.3% plain articaine (p<0.05), except for control groups and 0.1% plain articaine (p>0.05). IL-6 release was not affected by liposomal formulations (p>0.05); all concentrations of plain articaine increased IL-6 release in relation to the controls and to each correspondent liposomal formulation (p<0.05). In conclusion, liposome with transmembrane pH gradient increases articaine encapsulation in relation to that described in the literature, however it presented intrinsic in the model evaluated / Mestrado / Farmacologia, Anestesiologia e Terapeutica / Mestre em Odontologia

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / In the present work, behavioral, neurochemical (determination of monoamines and metabolites levels rat in striatum), histopatological and biochemical (lipoproteins and transaminases) alterations produced by cocaine, ethanol and the association of theses were analyzed. Females Wistar rats (180-200 g) were treated during 7 days with cocaine (Coc 10 and 20 mg/kg, i.p.), ethanol (Et 2 and 4g/kg, p.o.) and the association of theses (Coc 10 mg + Et 2g - low interaction doses; Coc 20 mg + Ethanol 4g - high interaction doses). The results demonstrated that the spontaneous locomotor activity (SLA) was increased after cocaine administration and decreased after ethanol in both doses. It was not observed alterations in the SLA in the association cocaine + ethanol. The treatment with cocaine and ethanol caused an increase in dopamine level. The association cocaine + ethanol in higher doses caused an increase of dopamine and serotonin and decrease of DOPAC levels, suggesting that those drugs would can actuate directly in those systems or, indirectly, across a process of modulation. Cocaine, ethanol and the association of theses, after subcronic administration and in both doses, caused a donwregulation of D2-like receptors, not by recurring alterations in the values of Kd. The values of Bmax and Kd of the M1 + M2-like receptors have not already suffered alterations. In the biochemical study, the administration of cocaine induced an increase the concentrations of TGO and triglycerides, and decrease of the concentrations of TGP, total cholesterol and HDL. The treatment with ethanol decreases the levels of HDL, total cholesterol and triglycerides. The association cocaine + ethanol caused in both doses decrease of triglycerides, HDL, TGP and total cholesterol. All treatments did promote histopatological alterations in cardiac and hepatic woven. Ours results suggest that the association cocaine + ethanol appears to interfere more intense in the systems of neurotransmitters and in the biochemical parameters than the use of the isolated drugs. / No presente trabalho foram estudadas as alteraÃÃes comportamentais, neuroquÃmicas (determinaÃÃes dos nÃveis de monoaminas e metabÃlitos), histopatolÃgicas e bioquÃmicas (lipoproteÃnas e transaminases) em corpo estriado de ratos tratados com cocaÃna e etanol isoladamente ou em associaÃÃo. Foram utilizadas ratas Wistar (180-200 g), que foram tratadas durante 7 dias com cocaÃna (Coc 10 e 20 mg/kg, i.p.), etanol (Et 2 e 4g/kg, v.o.) e a associaÃÃo destes (Coc 10 mg + Et 2g - interaÃÃo baixas doses; Coc 20 mg + Etanol 4g - interaÃÃo altas doses). Os resultados demonstraram que a atividade locomotora espontÃnea (ALE) foi aumentada apÃs administraÃÃo de cocaÃna em ambas as doses e diminuÃda apÃs a administraÃÃo de etanol em ambas as doses. NÃo foram observadas alteraÃÃes na ALE na associaÃÃo cocaÃna + etanol. O tratamento com cocaÃna e etanol causou um aumento de dopamina, sem alteraÃÃes nos demais neurotransmissores e metabÃlitos. A associaÃÃo cocaÃna + etanol em altas doses, promoveu aumento dos nÃveis de dopamina, diminuiÃÃo de DOPAC e aumento dos nÃveis de 5-HT, sugerindo que essas drogas poderiam atuar diretamente nesses sistemas ou, indiretamente, atravÃs de um processo de modulaÃÃo. A cocaÃna, etanol e a associaÃÃo destes, apÃs administraÃÃo sub-crÃnica e em ambas as doses, causou uma downregulation em receptores D2-sÃmile, nÃo ocorrendo alteraÃÃes nos valores de Kd. Os valores de Bmax e Kd dos receptores M1 + M2-sÃmile nÃo sofreram alteraÃÃes. No estudo bioquÃmico, a administraÃÃo de cocaÃna induziu um aumento nas concentraÃÃes de TGO e triglicerÃdeos, e diminuiÃÃo das concentraÃÃes de TGP, colesterol total e HDL. O tratamento com etanol diminuiu os nÃveis de HDL, colesterol total e triglicerÃdeos. A associaÃÃo cocaÃna + etanol promoveu em ambas as doses diminuiÃÃo de trigicerÃdeos, HDL, TGP e colesterol total. Todos os tratamentos promoveram alteraÃÃes histopatolÃgicas em tecido cardÃaco e hepÃtico. Nossos resultados sugerem que a associaÃÃo cocaÃna + etanol parece interferir de maneira mais intensa nos sistemas de neurotransmissÃo e nos parÃmetros bioquÃmicos do que o uso das drogas isoladas.

<p>UVOD. Bilijarna kalkuloza je najče&scaron;će oboljenje hepatobilijarnog sistema, a holecistektomija predstavlja jedan od najče&scaron;će izvođenih operativnih zahvata. Laparoskopska holecistektomija je danas zlatni standard lečenja holelitijaze. Laparoskopska holecistektomija je pokazala pobolj&scaron;anje u klinički značajnim ishodima kao &scaron;to su skraćenje operativnog vremena, kraća hospitalizacija, smanjenje jačine i trajanja postoperativnog bola i brži povratak dnevnim i radnim aktivnostima. Postoperativna bol i vreme potpunog oporavka ostaju dva glavna problema posle nekomplikovane laparoskopske holecistektomije koje bi trebalo pobolj&scaron;ati. Bol koji je povezan sa laparoskopskom holecistektomijom je kompleksan i multifaktorijalan. On nastaje o&scaron;tećenjem tkiva, disekcijom i uklanjanjem žučne kesice iz svoje lože, stimulacijom periportalnih nerava, iritacijom dijafragme, mehaničkim i hemijskim interakcijama gasa i pneumoperitoneuma, incizijama portova. Istraživanja su označila parijetalni i visceralni bol kao dva glavna mehanizma nastanka bola kod laparoskopske holecistektomije. Bol se ne može meriti nego proceniti jer je subjektivni osećaj. Pokazalo se potrebnim da se na čvr&scaron;ćim naučnim osnovama da odgovor na pitanje da li je moguće blokirati parijetalni i visceralni bol posle laparoskopske holecistektomije u akutnoj fazi. CILJEVI. Cilj studije je da uporedi standardnu analgeziju (ne-opioidnu) (grupa O) sa davanjem parijetalne blokade (grupa P), ili davanjem visceralne blokade (grupa V), ili sa obe date blokade (grupa P+V). Primarni ishodi studije su bolesnikov procenjeni bol pre operacije i posle operacije na 1, 2, 4, 6, 12, 24, 48 sati i 7. dana. Sekundarni ishodi studije su bolesnikova procenjena mučnina na 1,2,4,6,12 sati i bolesnikova procenjena mobilnost 1. 2. i 7. dan. HIPOTEZA. Blokada postoperativnog visceralnog bola i blokada postoperativnog parijetalnog bola posle laparoskopske holecistektomije putem intraperitonealne lokalne infiltracije anestetikom i putem lokalne infiltracije anestetikom pristupnih laparoskopskih portova može značajno smanjiti rani postoperativni bol. MATERIJAL I METODE. Ova prospektivna, randomizirana jednostruko slepa studija je započela septembra 2014. godine i trajala je do januara 2016. godine. Istraživanje je sprovedeno na Klinici za abdominalnu, endokrinu i transplantacionu hirurgiju i Urgentnom centru Kliničkog centra Vojvodine u Novom Sadu kod bolesnika operisanih metodom laparoskopske holecistektomije. Rad je podeljen u nekoliko celina. 1. Procena veličine uzorka; 2. Procena podobnosti za studiju; 3. Anketiranje i uključivanje u studiju; 4. Razvrstavanje u grupe i operativni rad; 5. Period postoperativnog praćenja; 6. Statistička obrada i pisanje rada.<br />1. Procena veličine uzorka. Studija je realizovana podelom bolesnika u 4 grupe. Neophodni broj bolesnika je izračunat uzimajući podatke iz pilot istraživanja slične studije iz 2012. godine. Veličina uzorka je računata za primarni ishod studije&nbsp; (bolesnikov procenjen bol sa NAS) na pretpostavci da treba biti 20% smanjenja bola u prvom postoperativnom satu, uz verovatnoću Tip 1 gre&scaron;ke &alpha;=0.05 i Tipa 2 gre&scaron;ke &beta;=0.10 da postigne adekvatnu statističku snagu oko 80% i da otkrije 20% razlike u srednjoj vrednosti procenjenog bola jedan sat nakon laparoskopske&nbsp; holecistektomije. Procenjeni broj ispitanika po grupama prema zadatim kriterijumima je bio (P+V=65; P=68; V=68; O=65). Studija je započela uključivanjem prvog bolesnika u studiju a zavr&scaron;ena ispunjenim periodom praćenja sve dok poslednji bolesnik nije doneo upitnike o bolu, mučnini i kretanju. 2. Procena podobnosti za studiju. U periodu studije ukupan broj holecistektomiranih bolesnika je bio 1024 (440 klasično i 584 laparoskopski). Samo pogodni bolesnici su anketirani (584) i pročitali su informacioni list o istraživanju. Uključivanje ili procena podobnosti bolesnika za studiju sprovedena je na osnovu uključnih i isključnih kriterijuma. U studiju nije uključeno ukupno 226 bolesnika. Od tog broja 82 bolesnika je odbilo učestvovati u studiji a 144 bolesnika nije ispunilo uključne postavljene kriterijume. Svojim potpisom potvrdilo je uče&scaron;će u studiji 358 bolesnika. 3. Anketiranje i uključivanje u studiju. Nakon prijema bolesnika u bolnicu ispitivači su uzimali anamnezu i bolesnicima je ponuđen informacioni list i informisani pristanak. Nakon čitanja informacije, potpisivanja informisanog pristanka i zadovoljavanja&nbsp; uključnih i isključnih kriterijuma 358 bolesnika je uključeno u studiju. Obavljena je preoperativna priprema i ispitivači su popunili deo podataka u individualnom listu. 4. Razvrstavanje u grupe i operativni rad. Neposredno preoperativno od strane nezavisne osobe neuključene u studiju napravljena je randomizacija izabranih (n=358) u studijske grupe tablicama slučajnog izbora, tako da bolesnici nisu znali kojoj grupi pripadaju, dok su operater i osoblje to znali na početku operacije (jednostruko slepa studija). Nakon randomizacije i operacije bolesnici pripadaju jednoj od sledeće 4 grupe: Kontrolna grupa O=89, u kojoj su bolesnici sa urađenom laparoskopskom&nbsp; holecistektomijom bez visceralne blokade anestetikom i bez parijetalne blokade anestetikom. Eksperimentalna grupa P=88, u kojoj su bolesnici sa urađenom laparoskopskom holecistektomijom bez visceralne blokade anestetikom i sa parijetalnom blokadom anestetikom. Eksperimentalna grupa V=92, u kojoj su bolesnici sa urađenom laparoskopskom holecistektomijom sa visceralnom blokadom anestetikom i bez parijetalne blokade anestetikom. Eksperimentalna grupa P+V=89, u kojoj će biti bolesnici sa urađenom laparoskopskom holecistektomijom sa visceralnom blokadom anestetikom i sa parijetalnom blokadom anestetikom. Primenjivan je uobičajni, standardni protokol anestezije za laparoskopske operacije kod svih ispitanika. Svim bolesnicima plasirana je orogastrična sonda koja se nakon operacije odstranjivala. Kod&nbsp; bolesnika kod kojih je primenjivan lokalni anestetik neposredno pre početka operacije pravio se rastvor lokalnog anestetika (Marcaine&reg; 0,25%). Bolesnici su otpu&scaron;teni sa bolničkog lečenja prvog postoperativnog dana, pod uslovom da nisu imali komplikacija. 5. Postoperativno praćenje i ispunjavanje upitnika. Po dolasku na odeljenje&nbsp; bolesnicima je odmah uključivana ista analgezija. Tokom ispunjavanja informisanog pristanka, bolesnici su dobili upitnik na kojoj će sami procenjivati nivo bola, mučnine i kretanja tokom ležanja u bolnici i vremena praćenja od 7 dana kući. Bolesnici su dolazili na unapred zakazane postoperativne kontrole 7 do 10 dana posle operacije i donosili ispunjene upitnike. Otpu&scaron;teno je i za praćenje ostalo n=302 laparoskopski operisanih bolesnika a isključeno iz studije n=20 bolesnika. 6. Statistička obrada i pisanje rada. Ukupno je analizirano 274 listića operisanih bolesnika: u Grupi P+V =67; u Grupi P =70; u Grupi V =70 i u Grupi O =67. Od osnovnih deskriptivnih statističkih parametara za kvalitativnu i kvantitativnu procenu dobijenih rezultata su kori&scaron;ćeni apsolutni brojevi, relativni brojevi, mediana, mod, aritmetička sredina i standardna devijacija (SD). Obrada podataka se vr&scaron;ila&nbsp; osnovnim i naprednim statističkim metodama i programima. Rezultati su prikazani tabelarno i grafički. REZULTATI. Demografski podaci. Ukupno je bilo 188 žena i 86 mu&scaron;karaca, u odnosu 2,2 : 1. Prosečna starost cele grupe je bila 52,1 &plusmn; 15,72 godine. Ukupno je bilo 179 zaposlenih i 95 nezaposlenih. Ukupno je bilo 45 ispitanika sa osnovnim obrazovanjem, 153 ispitanika sa srednjim obrazovanjem i 76 ispitanika sa visokim obrazovanjem. Ukupno je bilo 186 nepu&scaron;ača i 88 pu&scaron;ača. Prosečna vrednost BMI cele grupe je bila 27,24 &plusmn; 4,21 kg/m2. Prosečna vrednost ASA u celoj grupi je bila 2,03 (mediana=2, mod=2).

Today laparoscopic cholecystectomy represents the golden standard in treating cholelithiasis. Laparoscopic cholecystectomy showed improvement in the clinically significant outcomes, such as: reducing the duration of the surgery, shorter hospital stay, reducing the intensity and duration of postoperative pain and faster return to normal daily and working activities. Postoperative pain and the time of full recovery remain the two major problems after a non-complicated laparoscopic cholecystectomy and they should be improved. The pain related to laparoscopic cholecystectomy is complex and multi-factorial in origin. The pain occurs due to damaged tissues, dissection and removal of gallbladder from its cavity, stimulation of periportal nerves, irritation of the diaphragm, mechanical and chemical interaction of gases and pneumoperitoneum and port incisions. Researches have denoted parietal and visceral pains as two major mechanisms in occurrence of pain in laparoscopic cholecystectomy. Pain cannot be measured, but estimated, as it is a subjective feeling. It was considered necessary to find the answer, based on solid scientific evidence, if it was possible to block parietal and visceral pain after laparoscopic cholecystectomy in its acute phase. OBJECTIVES: The aim of this study is to compare standard, non-opioid, analgesia (group O) with applying parietal blockade (group P), or visceral blockade (group V), or compare with both applied blockades (group P+V). The primary outcomes of the study are the patient&acute;s estimated pain before surgery and 1, 2, 4, 6, 12, 24, 48 hours and 7th day after the surgery. The secondary outcomes of this study are the patient&acute;s estimated nausea level during 1, 2, 4, 6, 12 hours, along with the patient&acute;s estimated mobility 1st, 2nd and 7th day, postoperatively. HYPOTHESIS. Blockade of postoperative visceral pain and blockade of postoperative parietal pain following laparoscopic cholecystectomy, applying intraperitoneal local infiltration with anesthetic and also by local infiltration with anesthetic through accessible laparoscopic ports, can significantly reduce early postoperative pain. MATERIAL AND METHODS: This prospectively randomized single-blinded study started in September 2014 and lasted up to January 2016. The research was carried out at the Clinic for Abdominal, Endocrine and Transplantation Surgery and Emergency Center, Clinical Center of Vojvodina in Novi Sad and it involved patients who underwent laparoscopic cholecystectomy. This study has been divided into several units. 1. Assessment of sample size; 2. Assessment of eligibility for the study; 3. Survey and inclusion in the study; 4. Group formation and operational work; 5. Period of postoperative follow-up; 6. Statistical processing and writing the paper.1. Assessment of sample size. The study was realized by dividing the patients into 4 groups. The number of patients necessary was determined based on the data taken as pilot study from a similar study from 2012. Sample size was calculated for the primary outcome of the study (patient&acute;s estimated pain with NAS) based on the assumption that a pain reduction of 20% should occur during the first postoperative hour, with the probability of Type 1 error &alpha;=0.05 and Type 2 error &beta;=0.10 to reach the adequate statistical power of about 80%, and to reveal 20% difference in the average value of the estimated pain one hour after the laparoscopic cholecystectomy. The assessed number of respondents in groups according to the set criteria was (P+V =65;P =68;V =68; O =65). The study started when the first patient was included and it ended with the complete follow-up period when the last patient handed in the survey about pain, nausea and mobility. 2. Assessment of eligibility for the study. During the study the number of patients undergoing surgery applying the method of cholecystectomy was 1024 (440 classical and 584 laparoscopic). Only the suitable patients were surveyed (584) and given to read the information leaflet about the study. Inclusion and assessment of patients&acute; eligibility was performed on the basis of inclusion and exclusion criteria. A total of 226 patients was not included in the study. Out of that number 82 patients refused to participate in the study and 144 did not fulfill the inclusive criteria set. By signing 358 patients confirmed their participation in the study. 3. Survey and inclusion in the study. After admitting the patients to hospital the surveyors took their anamnesis and the patients were offered an information leaflet and informed consent. Following the reading of the information leaflet, signing the informed consent and satisfying the criteria for inclusion and exclusion, 358 patients were included in the study. Preoperative preparations were performed and the surveyors filled in some of the data on the individual list. 4. Group formation and operational work. Prior to the surgery an independent person not included in the study carried out the randomisation of the patients chosen (n=358) into study groups by random selection tables. The patients did not know which group they belonged to, while it became known to the surgeon and the operation stuff at the beginning of the surgery (singleblinded study). After randomization and surgery the patients belonged to one of the following groups: Control group O=89 of patients with performed laparoscopic cholecystectomy without visceral blockade by anesthetic and without parietal blockade by anesthetic. Experimental group P=88 of patients with performed laparoscopic cholecystectomy without visceral blockade by anesthetic but with parietal blockade by anesthetic. Experimental group V=92 of patients with performed laparoscopic cholecystectomy with visceral blockade by anesthetic but without parietal blockade by anesthetic. Experimental group P+V=89 of patients with performed laparoscopic cholecystectomy with visceral blockade by anesthetic and with parietal blockade by anesthetic. The standard protocol of anesthesia for laparoscopic cholecystectomy was applied to all patients. An orogastric tube used during the surgery, was removed after it. In patients with applied local anesthetic immediately before surgery a solution of local anesthetic was made (Marcaine&reg; 0,25%). The patients were discharged from hospital the first postoperative day, provided that no complications occurred. 5. Postoperative follow-up and completing the questionnaire. When admitted to the ward the patients were given the same kind of analgesia. While completing the informed consent the patients were given a questionnaire for estimating their pain level, nausea and mobility during their stay in hospital and during the 7-day follow-up period at home. The patients were required to come for 7 and 10-day postoperative check-ups by appointment and then they handed in the questionnaires. n=302 patients with performed laparoscopic cholecystectomy were released and designated for follow-up, and n=20 patients were excluded from the study. 6. Statistical processing and writing the paper. In total 274 operated patients&acute; slips were analysed, by groups as follows: in Group P+V =67; in Group P =70; in Group V =70 and in Group O =67. From the basic descriptive statistical parametres for qualitative and quantitative assessment of results obtained, absolute numbers, relative numbers, the median, mode, arithmetic mean and standard deviation (SD) were used. Data processing was carried out using basic and advanced statistical methods and programmes. The results are presented in tabular and graphical manner. RESULTS. Demographic data. In total there were 188 women and 86 men, in proportion 2,2 : 1. The average age of the whole group was 52,1 &plusmn; 15,72 years. In total there were 179 employed and 95 unemployed persons. In total there were 45 surveyed patients with primary education, 153 surveyed patients with secondary education and 76 surveyed patients with higher education. In total there were 186 nonsmokers and 88 smokers. The mean BMI value of the whole group was 27,24 &plusmn; 4,21 kg/m2. The mean value of ASA of the whole group was 2,03 (the median=2, mode=2). There is no significant difference among the groups observed considering the observed parametres. Laboratory data. There is a statistically significant difference in the value of leukocytes among the observed groups (p=0,039), and in the value of urea among the observed groups (p=0,040). There is no statistically significant difference in the value of the erythrocyte, platelets, hemoglobin, blood glucose, creatinine and bilirubin of the&nbsp; observed groups. Operative and postoperative data. There is no statistically significant difference in the amount of Fentanyl&reg; applied among the observed groups. There is statistically significant difference in the length of the surgery among the observed groups (p=0,003), in the duration of the positioning of abdominal drainage among the observed groups (p=0,024), in the duration of hospital stay among the observed groups (p=0,027), in the number of days until getting back to regular activities among the observed groups&nbsp; (p=0,000), in the number of taken pills among the observed groups (p=0,000). The patients&acute; average satisfaction grade after surgery in the whole group was 8,80 (the median=9; mode=10). Group P+V had the best patient&lsquo;s satisfaction grade after the surgery. Assessment of pain, nausea and mobility. There is statistically significant difference in the estimation of pain intensity before surgery among the observed groups (p=0,003). There is statistically significant difference in the estimation of pain intensity 1 hour after surgery among the observed groups (P+V having the best estimated pain); in the estimation of pain intensity 2 hours after&nbsp; surgery (P+V having the best estimated pain); in the estimation of pain intensity 4 hours after surgery (P having the best estimated pain); in the estimation of pain intensity 6 hours after surgery (P+V having the best estimated pain); in the estimation of pain intensity 12 hours after surgery (P+V having the best estimated pain); in the estimation of pain intensity 24 hours after surgery (P+V having the best estimated pain); in the estimation of pain intensity 48 hours after surgery (P having the best estimated pain) also in the estimation of pain intensity 7 days after surgery (P having the best estimated pain). The estimated pain intensifies at about 2,5 hours after surgery and peaks 3 hours after surgery, and decreases to the same level as it was during 2nd hour after surgery approximately during 5th hour after surgery. There is considerable improvement in mobility of patients in the time interval 1st, 2nd and 7th postoperative days. There is considerable improvement in estimated nausea level of patients in the time interval 1, 2, 4, 6 and 12 hours. Correlations. Statistically significant positive correlation in estimated pain after 1st hour, after 2nd hour, after 6th hour and after 12th hour was determined by the number of tablets taken (p=0,000), just like the estimated nausea level (p=0,000). Statistically significant positive correlation in estimated pain after 4th hour was determined by the number of tablets taken (p=0,006), just like the activities (p=0,014). Statistically significant positive correlation in estimated pain after 24th hour was determined by the number of tablets taken (p=0,000; positive), and by the duration of the surgery (p=0,028; negative). Statistically significant positive correlation in estimated pain after 48th hour and after 7 days was determined by the number of tablets taken (p=0,000). CONCLUSIONS: The application of local anesthetic, regardless of how it was applied, considerably reduces pain after laparoscopic cholecystectomy. The application of local anesthetic by port or viscerally (P+V) considerably reduces pain compared to only by port (P) or only visceral (V) application in the time intervals of 2, 6, and 12 hours after laparoscopic cholecystectomy. The application of local anesthetic by port (P), with or without visceral (V), considerably reduces pain in the time intervals of 1, 4, 24, and 48 hours and 7 days after laparoscopic cholecystectomy. The best mobility was shown by group P+V after laparoscopic cholecystectomy. Estimated nausea was most reduced in group P after laparoscopic cholecystectomy. Group P+V presented the earliest return to regular activities. The best patients&acute; satisfaction grade with surgical treatment was shown by group P+V. Postoperative pain is most considerably positively correlated with the estimated nausea and pills taken, from the moment of patient&acute;s release from hospital to the first check-up.<br />&nbsp;</p>

INTRODUÇÃO: A segurança da administração de anestésicos locais com vasoconstritor em pacientes diabéticos submetidos à cirurgia oral não está bem fundamentada na literatura. OBJETIVO: Investigar a ocorrência de variação da glicemia nos períodos pré, trans e pós-operatório de exodontia de dentes superiores, sob anestesia local com lidocaína 2% sem e com adrenalina 1:100.000, em portadores de diabetes mellitus tipo 2. Secundariamente, avaliar os efeitos hemodinâmicos e o grau de ansiedade. MÉTODOS: Estudo prospectivo e randomizado com pacientes portadores de diabetes acompanhados na Unidade Clinica de Coronariopatia Crônica do Instituto do Coração do Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo. A monitorização contínua da glicemia durante 24 horas foi realizada através do MiniMed Continuous Glucose Monitoring System (CGMS, Medtronic). Os pacientes foram divididos em dois grupos: LSA - que recebeu 5,4 mL lidocaína 2% sem adrenalina e LCA - que recebeu 5,4 mL de lidocaína 2% com adrenalina 1:100.000. Os níveis de glicemia foram avaliados nas 24 horas (período basal) e nos tempos determinados: uma hora antes, durantes e até uma hora após a exodontia (período de procedimento). Os parâmetros hemodinâmicos foram avaliados por meio de um medidor de pressão arterial digital automático e o nível de ansiedade através de uma escala. RESULTADOS: Dos 400 pacientes avaliados, 70 foram incluídos no estudo, sendo 35 randomizados no grupo LSA e 35 no grupo LCA. A análise das médias da glicemia nos grupos LSA e LCA durante os períodos (basal e procedimento) não demonstrou diferença estatisticamente significativa (p=0,229 e p=0,811, respectivamente). Também não houve diferença significativa (p=0,748) na glicemia entre os grupos em cada tempo avaliado. Entretanto, nos dois grupos houve decréscimo significativo da glicemia (p < 0,001) ao longo dos tempos avaliados. Os grupos LSA e LCA não apresentaram diferenças significativas em relação à PAS (p=0,176), à PAD (p=0,913), à FC (p=0,570) e ao nível de ansiedade. CONCLUSÃO: A administração de 5,4mL de lidocaína 2% com adrenalina 1:100.000 não provocou alteração significativa da glicemia, parâmetros hemodinâmicos e nível de ansiedade em relação ao grupo sem vasoconstritor / INTRODUCTION: The safety of administration of local anesthetics with epinephrine for diabetic patients undergoing oral surgery is not well grounded in the literature. OBJECTIVE: To investigate the occurrence of variation of glucose in the pre, intra and postoperative extraction of upper teeth under local anesthesia with lidocaine 2% with and without 1:100.000 epinephrine in patients with type 2 diabetes mellitus. Secondly, to evaluate the hemodynamic effects and degree of anxiety. METHODS: A prospective randomized study of patients with diabetes attended in Coronary Chronic Clinics Unit, Heart Institute, Hospital das Clinicas in University of São Paulo Medical School. Continuous monitoring of blood glucose for 24 hours was performed using MiniMed Continuous Glucose Monitoring System (CGMS, Medtronic) and the patients were divided into two groups: LSA - which received 5.4 mL of 2% lidocaine without epinephrine and LCA - which received 5.4 mL of 2% lidocaine with 1:100,000 epinephrine. Blood glucose levels were assessed at 24 hours (baseline period) and at certain times: one hour before, during, and up to one hour after oral surgery (procedure period). We evaluated the hemodynamic parameters through a digital automatic pressure meter and anxiety level was measured by the scale. RESULTS: Of 400 patients evaluated, 70 were included in these study, 35 were randomized in the LSA group and 35 in the group LCA. The analysis of mean glicemia in groups LSA and LCA during the baseline period and procedure showed no statistically significant difference (p = 0.229 and p = 0.811, respectively). There was no difference in blood glucose (p = 0.748) between the groups at each time evaluated. However, in both groups there was a significant decrease in blood glucose (p < 0.001) over the time periods studied. The groups showed no significant differences regarding SBP (p = 0.176), DBP (p = 0.913), HR (p = 0.570) and anxiety level. CONCLUSION: The administration of 5.4 mL of 2% lidocaine with epinephrine 1:100.000 caused no significant change in blood glucose, hemodynamic parameters and level of anxiety compared to the group without vasoconstrictor

O objetivo deste estudo foi investigar o comportamento da pressão arterial e o papel da ansiedade durante tratamento odontológico em hipertensos. Foram avaliados 65 hipertensos sob tratamento anti-hipertensivo (pressão arterial = 140/90 mm Hg) com teste de ansiedade IDATE (n=34), medidas de pressão arterial de 2/2 minutos (aparelho oscilométrico automático) e pela MAPA (n=42) com medidas de 15/15 minutos durante 8 horas nos dias dos experimentos odontológicos Verificou-se elevação da pressão arterial sistólica de curta duração e pequena magnitude ( < 10 mm Hg) independentemente do uso de prilocaína com ou sem felipressina. Os pacientes com ansiedade apresentaram pressão arterial maior do que os sem ansiedade em alguns procedimentos sugerindo que a ansiedade pode ter papel na elevação da pressão arterial / The objective of this study was to investigate the behavior of blood pressure and the role of anxiety during dental treatment of hypertensive patients. An evaluation was made of sixty-five hypertensive patients (blood pressure = 140/90 mm Hg) under anti-hypertensive treatment were evaluated by the IDATE anxiety test (n = 34), blood pressure measurements 2/2 minutes (automatic oscillometric device), and ABPM (n = 42) with 15/15 minutes measurements, during 8 hours on the days of the two dental experiments. Evaluation an increase in systolic pressure of short duration and little magnitude ( < 10 mm Hg) was found, regardless of using prilocaine with or without felypressin. During some procedures, the patients presenting anxiety had higher blood pressure than those without anxiety, suggesting that anxiety may play a role in the increase of blood pressure
