Estudo prospectivo das complicações respiratórias da palatoplastia primária em crianças com fissura de palato. / Prospective study of respiratory complications of primary palatoplasty in infants with cleft palate

Priscila Capelato Prado Conegliam 04 October 2013 (has links)
Objetivo: Investigar a incidência de complicações respiratórias trans e pós-operatórias em crianças com fissura de palato submetidas à palatoplastia primária, com vistas à identificação de sinais e sintomas de apneia obstrutiva do sono (AOS). Modelo/Local de Execução: Estudo prospectivo realizado no Hospital de Reabilitação de Anomalias Craniofaciais. Participantes: Setenta e seis crianças não-sindrômicas, de ambos os sexos, foram divididas em dois grupos: um constituído por 56 crianças com fissura de palato (FP), idade entre 11 e 15 meses, sendo 20 com fissura de lábio e palato unilateral (FLPU), 16 com fissura de lábio e palato bilateral (FLPB), 20 com fissura de palato isolada (FPi), e, outro, controle, constituído por 20 crianças com fissura de lábio (FL), idade entre 3-13 meses. As crianças do grupo FP foram submetidas à palatoplastia primária pela técnica de von Langenbeck modificada e o grupo controle, à queiloplastia pela técnica de Millard. Variáveis: Dados referentes à história clínica e sintomas respiratórios foram levantados junto aos pais no pré-operatório (PRE), i.e., no período de 1 a 2 dias que antecederam a cirurgia primária. Foram, ainda, analisadas as complicações respiratórias observadas no transoperatório (TRANS) e em três momentos do pós-operatório: imediato (POSi), i.e., na sala de recuperação anestésica, mediato (POSm), i.e., 12 a 24 horas após a cirurgia estando o paciente ainda hospitalizado, e, tardio (POSt), i.e., 1 a 2 meses após a alta hospitalar, por contato telefônico. Com base na identificação de dificuldade respiratória, ronco e apneia durante o sono foi calculado um escore clínico (índice de Brouillette) no PRE, POSi e POSt, de modo a identificar crianças com suspeita de AOS. Resultados: A análise do índice de Brouillette mostrou aumento do escore médio, sugestivo da possível presença de AOS, apenas no POSi. Nas demais abordagens, observou-se que o grupo FP, comparativamente ao grupo controle, apresentou complicações respiratórias com frequência significantemente maior (p<0,05), particularmente no POSi. Proporção significantemente maior de crianças com FP apresentou ronco. Pausas ventilatórias no sono não foram relatadas. Conclusão: O fechamento cirúrgico do palato exerce efeito obstrutivo sobre a via aérea superior a curto prazo, em decorrência da manipulação cirúrgica, levando a sintomas respiratórios transitórios, em sua maioria. Contudo, o elevado número de relatos de ronco a longo prazo, não permite descartar a ocorrência de AOS nessa população. Estudos polissonográficos devem ser realizados para investigar em maior profundidade esta relevante questão clínica / Objective/Purpose: To investigate the incidence of trans- and postoperative respiratory complications in infants with cleft palate undergoing primary palatoplasty, in order to identify signs and symptoms of obstructive sleep apnea (OSA). Study model/Setting: Prospective study, carried out at the USP Hospital for Rehabilitation of Craniofacial Anomalies. Design/Participants: Seventy-six non-syndromic infants, both genders, were divided into two groups: CP group (56 infants with cleft palate±lip, aged 11-15 months, comprising 20 with unilateral cleft lip and palate, 16 with bilateral cleft lip and palate and 20 with isolated cleft palate), and CL control group (20 infants with cleft lip, aged 3-13 months). CP infants underwent palatoplasty using a modified von Langenbeck technique, and control infants underwent cheiloplasty using the Millard technique. Main outcome measures: Data based on parent reports of clinical history and respiratory symptoms were collected 1-2 days preoperatively (PRE). Respiratory complications were assessed during surgery (TRANS) and three times postoperatively: in the recovery room (POST1); 12-24 hours after surgery, while the patient was still hospitalized (POST2) and 1-2 months after hospital discharge, by telephone parental report (POST3). Based on the identification of breathing difficulty, snoring and breathing pauses during sleep, a clinical score was calculated (Brouillette index) at PRE, POST1 and POST3, in order to identify infants with suspected OSA. Results: Brouillette index analysis showed an increase in mean score, suggestive of OSA, only at POST1. On the other approaches, the CP group showed higher frequency of respiratory complications than the control group, (p<0.05), mainly at POST1. A significantly higher number of infants with CP presented snoring. Breathing pauses during sleep were not observed/reported. Conclusion: The surgical closure of the palate has an obstructive effect on the upper airway in the short-term due to surgical manipulation, mainly leading to transitory respiratory symptoms. However, the high number of snoring reports at the long-term, does not allow to rule out the occurrence of OSA in this population. Polysomnography studies shall be carried out to further investigate this relevant clinical issue.

Impacto da sinusectomia funcional endoscópica na qualidade de vida de pacientes com imunodeficiência comum variável e rinossinusite crônica / Impact of functional endoscopic sinus surgery on quality of life in patients with common variable immunodeficiency and chronic rhinosinusitis

Tatiana Regina Teles Abdo 23 March 2011 (has links)
Pacientes com imunodeficiência comum variável (ICV) são susceptíveis à ocorrência de infecções bacterianas de repetição, sendo a rinossinusite uma das mais prevalentes. Ainda que muitos pacientes apresentem melhora clínica após o início da terapia de reposição de gamaglobulinas, a rinossinusite crônica (RSC) permanece como um problema para esses pacientes. A sinusectomia funcional endoscópica (FESS) é indicada na falha do tratamento clínico maximizado na RSC. Entretanto, há carência de estudos que avaliem o impacto da sinusectomia no tratamento da RSC em pacientes com ICV. Neste estudo prospectivo, descrevemos o impacto da FESS na qualidade de vida de 16 pacientes com ICV e RSC em reposição de gamaglobulina, analisamos as modificações na intensidade dos sintomas clínicos e na endoscopia nasal entre o pré-operatório e pós-operatório de 1 ano desses pacientes, a redução do uso de antibioticoterapia e o quadro de RSC no pós-operatório. Utilizamos o SNOT-20p para a análise da qualidade de vida; a escala analógica visual (VAS) para a análise dos sintomas; os critérios de LundKennedy para a endoscopia e os critérios de Lund-MacKay para a tomografia. A pontuação total (2,52±1,05(1,5-4,40) vs. (1,92±1,40(0,70-3,55), p=0,008) e a pontuação nos cinco itens considerados mais importantes (4,10±1,35(2.6-5.00) vs. 2,90±1,75(1,20-4,60), p=0,003) apresentadas pelos pacientes no questionário SNOT-20p apontaram uma diferença estatisticamente significante entre o pré-operatório e o pósoperatório de 1 ano. Quanto ao quadro geral de rinossinusite, 62,5% dos pacientes referiram melhora, 25% não perceberam diferença e 12,5% sentiram-se piores no pós-operatório de 1 ano. A redução de uso de antibiótico foi verificada em 68,8% dos pacientes. Ainda, a comparação dos valores pré-operatórios e pós-operatórios das queixas de obstrução nasal, rinorreia e congestão/dor na face e da endoscopia foi estatisticamente significante. Nossos achados sugerem que pacientes com ICV e RSC apresentam melhora na qualidade de vida, dos sintomas e da endoscopia nasal em 1 ano de pós-operatório quando submetidos à FESS, além da redução do uso de antibióticos e melhora no quadro de rinossinusite / Patients with common variable immunodeficiency (CVID) are susceptible to recurrent bacterial infections, of which rhinosinusitis is one of the most prevalent. Although many patients experience clinical improvement with gamma-globulin replacement therapy, chronic rhinosinusitis (CRS) remains an issue. Functional endoscopic sinus surgery (FESS) is indicated in the treatment of CRS when clinical treatment options have been exhausted. Few studies have assessed the impact of FESS in the treatment of CVID patients with CRS. This prospective study describes the impact of FESS on quality of life in 16 patients with CVID and CRS undergoing immunoglobulin replacement therapy, assesses endoscopic and clinical changes (symptom intensity) between the preoperative period and 1-year follow-up, and evaluates postoperative reductions in antibiotic use and overall improvement of CRS symptoms. The Sino-Nasal Outcome Test (SNOT-20) was used for assessment of quality of life. Symptom intensity was scored on a visual analog scale (VAS), and the LundKennedy and Lund-MacKay scores were used in endoscopic and CT assessment respectively. At one-year follow-up, SNOT-20 scores had significantly improved from baseline (total score, 2,52±1,05 (range, 1,50-4,40) vs. 1,92±1,40 (0,70-3,55), p=0,008; five most important items, 4,10±1,35 (2,60-5,00) vs. 2,90±1,75 (1,20-4,60), p=0,003). Also at one-year follow-up, 62.5% of patients reported clinical improvement and 25% reported no perceivable difference in symptoms, whereas 12,5% felt worse than at baseline. Reductions in antibiotic use were achieved in 68.8% of patients. Comparison of pre- and postoperative clinical complaints (nasal obstruction, nasal discharge or congestion, facial pain) and endoscopic findings showed statistically significant differences. These findings suggest that patients with CVID and CRS experience significant improvement in quality of life, symptoms, and endoscopic abnormalities within one year of FESS, as well as reduced antibiotic use and overall improvement in rhinosinusitis-related clinical manifestations

Vânia Tie Koga Ferreira 03 July 2009 (has links)
A dor após o tratamento por câncer de mama é comum, pode ter várias causas, este sintoma caracteriza-se por redução funcional e emocional importante. Objetivo: Descrever a dor em mulheres com câncer de mama, identificar fatores de melhora e piora da dor, avaliar a interferência da dor na vida das mulheres, caracterizar e localizar a dor de mulheres submetidas ao tratamento por câncer de mama. Métodos: A amostra constituiu de 30 mulheres submetidas ao tratamento por câncer de mama, freqüentando um núcleo de reabilitação durante o período de fevereiro a agosto de 2008, e que responderam a um formulário acerca da doença, do tratamento e da dor. Foi aplicado o Inventário Breve de Dor (IBD) e o Questionário de McGill Br-MPQ e uma imagem para identificar o local o da dor. Resultados: A maioria das mulheres tinha idade superior a 50 anos, era casada, raça branca, católica, e do lar/dona de casa. Em relação ao tipo de cirurgia e a lateralidade observase uma distribuição equitativa entre mastectomia total e quadrantectomia, e lado direito e esquerdo, respectivamente. A maioria das mulheres realizou esvaziamento axilar, além de radioterapia e quimioterapia. A dor teve início após a cirurgia da mama em 46,7% das mulheres, com freqüência diária e constante, interferindo no humor e no sono das mulheres entrevistadas. Os movimentos relacionados ao aumento da dor foram alcançar, empurrar, apoiar e puxar. A maioria das mulheres relatou a prática de massagem para alívio da dor.. A dor após o tratamento por câncer de mama foi caracterizada como latejante, que irradia, que repuxa, chata, incômoda, que prende e deixa tensa. As alterações emocionais aumentaram a dor em (43,3%) das mulheres, o descansar/relaxar diminuiu a dor para metade e a maioria delas referiu suportar as dores. O local mais escolhido pelas mulheres para identificar a dor foram a região torácica superior e o braço entre linha do cotovelo e altura axilar na vista frontal da imagem. Conclusão: os dados apontam que a dor é um sintoma importante nas mulheres após o tratamento por câncer de mama, e esta deve ser valorizada por profissionais de saúde que as acompanham, são necessários mais estudos que possam elucidar questões como fatores osteomioarticulares e evolução do sintoma no pré e pós operatório. / Introduction: Pain after breast cancer treatment is common, may have several causes, this symptom is characterized by an important reduced functional and emotional . Objective: To describe the pain in women with breast cancer, identify factors of improvement and worsening of pain in the lives of women, identify and locate the pain of women undergoing treatment for breast câncer. Methods: The sample consisted of 30 women undergoing treatment for breast cancer, attending a rehabilitation center during the period February to August of 2008, and responding to a form of the disease, treatment and pain. The Brief Pain Inventory (IBD) and the McGill Questionnaire - MPQ-Br - were applied and an image to identify the location of the pain. Results: Most women were aged over 50 years, were married, white, Catholic, and housewife. Regarding the type of surgery and laterality there is an equitable distribution between total mastectomy and quadrantectomy, and right and left side, respectively. Most women held axillary dissection, and radiotherapy and chemotherapy. The pain began after the breast surgery in 46.7% of the women, daily frequency, and constantly, interfering with sleep and mood of the women interviewed. Movements related to increased pain were reaching, pushing, pulling and supporting. Most of the women reported the practice of massage for pain relief .. The pain after treatment for breast cancer was characterized as pulsatile, which radiates, boring, annoying, that sticks and leaves tense. Emotional changes in women increased (43.3%) the pain, resting / relaxing decreased the pain to half and most of them said they can bear pain. The place mostly chosen by women to identify the pain were the chest and upper arm between the elbow and line height in axillary front view of the image. Conclusion: Data suggest that pain is an important symptom in women after treatment for breast cancer, and it should be valued by health professionals who accompany them, are necessary further studies that may clarify issues as factors osteomioarticulares and development of the symptom the pre and post operatively.

Avaliação perioperatória em cães idosos submetidos à anestesia geral inalatória: determinação das complicações trans e pós-operatórias / Perioperative evaluation in elderly dogs undergoing inhalation anesthesia: determination of intraoperative and postoperative complications

Haley Silva de Carvalho 05 August 2011 (has links)
Este estudo objetivou avaliar a condição clínica pré-operatória dos cães idosos submetidos à anestesia inalatória e relacionar as alterações encontradas na avaliação pré-operatória com a ocorrência de complicações e óbito perioperatório. O estudo foi prospectivo, observacional e realizado no período de abril de 2007 a abril de 2008. Os cães idosos foram avaliados por meio de anamnese, exame físico, mensuração da pressão arterial sistólica (Doppler), eletrocardiograma (ECG) e análises laboratoriais previamente ao procedimento cirúrgico. O procedimento anestésico, cirúrgico e a ocorrência de complicações transoperatórias foram analisados pelo registro nas fichas de anestesia. Incluíram-se no estudo os animais submetidos à anestesia inalatória por no mínimo 30 minutos. As complicações pós-operatórias foram avaliadas por meio da consulta pós-operatória, do registro nos prontuários e relato dos proprietários. Os grupos foram comparados por meio do teste de Mann-Whitney. Nas variáveis categóricas foi empregado o teste do qui-quadrado ou o teste exato de Fisher. O grau de significância foi de 5%. Foram incluídos no estudo 169 cães, 97 machos e 72 fêmeas, com idade média de 10,4&plusmn;2,2 anos (125,0&plusmn;26,6 meses) e com peso médio de 19,8&plusmn;12,3 kg. A idade e peso não apresentaram diferença entre os sexos (p&gt;0,05). O hematócrito abaixo dos valores normais ocorreu em 16,0% (27/169) dos animais e houve associação com a ocorrência de complicações (21/169=12,43%) e óbito (4/169=2,37%) perioperatório (p&lt;0,01). A concentração de hemoglobina abaixo dos valores normais (4/169=2,37%) e a necessidade de transfusão de hemocomponentes foram associadas com o desfecho de óbito no pós-operatório (p&lt;0,01). Os animais classificados com categoria de risco anestésico (ASA) III (34/169=20,12%) e IV (2/169=1,18%) apresentaram maior ocorrência de complicações (p&lt;0,05) e óbito (p&lt;0,01) perioperatório quando comparado a ASA II (133/169=78,70%). Nos cães categorizados com risco cirúrgico médio (96/169=56,80%) e alto (9/169=5,33%) ocorreu maior morbidade e mortalidade perioperatório quando comparado ao baixo (64/169=37,87%) (p&lt;0,01). Houve menor mortalidade com o emprego da acepromazina (89/169=52,66%) na medicação pré-anestésica (p&lt;0,05). A hipotensão arterial foi a complicação mais frequente (78/169=46,15%) no transoperatório, mas não foi associada ao uso de acepromazina e desfecho de óbito (p&gt;0,05). A administração de fentanil em bolus (54/169=31,95%) foi associada com a hipotensão arterial transoperatória (p&lt;0,05). A duração do procedimento anestésico acima de 75 minutos apresentou maior ocorrência de complicações perioperatórias (p&lt;0,01). A morbidade e mortalidade perioperatória observada nos cães idosos foi de 56,21% (IC95%: 48,38-63,82%) e 2,96% (IC95%: 0,97-6,77%), respectivamente. A partir dos resultados pode-se concluir que: o hematócrito abaixo do valor de referência indica maior ocorrência de complicações e óbito perioperatório; a concentração de hemoglobina abaixo do valor de referência e a necessidade de transfusão de hemocomponentes determinam maior mortalidade perioperatória; a classificação de risco anestésico e cirúrgico são métodos válidos na determinação dos pacientes mais propensos a ocorrência de complicações e o desfecho de óbito; a administração de acepromazina reduz a mortalidade; o procedimento anestésico superior a 75 minutos aumenta a ocorrência de complicações; e a morbidade e mortalidade perioperatória são elevadas nos cães idosos. / This study aimed to evaluate the preoperative clinical condition in elderly dogs undergoing inhalation anesthesia and relate the changes found in the preoperative evaluation with the occurrence of perioperative complications and death. This study was prospective, observational and accomplished from April 2007 to April 2008. The elderly dogs were evaluated by clinical history, physical examination, measurement of systolic blood pressure (Doppler), electrocardiogram (ECG) and laboratory tests before surgery. The anesthetic and surgical procedure and the occurrence of intraoperative complications were analyzed according to the anesthesia records. This study included the animals submitted to inhalation anesthesia for at least 30 minutes. The postoperative complications were evaluated by postoperative visit, enrollment in medical records and owners&#39; reporting. The groups were compared using the Mann-Whitney test. For the categorical variables it was used the chi-square or Fisher&#39;s exact test. The level of significance was 5%. The study included 169 dogs, 97 males and 72 females, mean age 10.4&plusmn;2.2 years old (125.0&plusmn;26.6 months old) and mean weight was 19.8&plusmn;12.3 kg. The age and weight did not differ between the genders (p&gt;0.05). The hematocrit below normal values occurred in 16.0% (27/169) of the animals and was associated with the occurrence of perioperative (p&lt;0.01) complications (21/169=12.43%) and death (4/169=2.37%). The hemoglobin concentration below normal values (4/169=2.37%) and the need for blood components transfusion were associated with the outcome of postoperative death (p&lt;0.01). The animals classified as anesthetic risk category (ASA) III (34/169=20.12%) and IV (2/169=1.18%) had a higher perioperative complication (p&lt;0.05) and death (p&lt;0.01) compared to ASA II (133/169=78.70%). The dogs categorized as moderate (96/169=56.80%) and high (9/169=5.33%) surgical risk had higher perioperative morbidity and mortality when compared to low (64/169=37.87%) (p&lt;0.01). There was a lower mortality with the use of acepromazine (89/169=52.66%) in premedication (p&lt;0.05). Hypotension was the most frequent complication (78/169=46.15%) during surgery, but was not associated with the use of acepromazine and outcome of death (p&gt;0.05). The administration of fentanyl (54/169=31.95%) was associated with intraoperative hypotension (p&lt;0.05). The duration of anesthesia for over 75 minutes had a higher incidence of perioperative complications (P&lt;0.01). The perioperative morbidity and mortality observed in older dogs was 56.21% (95% CI: 48.38-63.82%) and 2.96% (95% CI: 0.97-6.77%), respectively. According to the results it can be concluded that: the hematocrit below the reference value indicates a higher incidence of perioperative complications and death; the hemoglobin concentration below the reference value and the need for blood components transfusion determine higher perioperative mortality; the classification of anesthetic and surgical risk are valid methods in determining the most likely patients to complications and outcome of death; acepromazine administration reduces mortality; anesthesia for over 75 minutes increases the complications; and perioperative morbidity and mortality are high in elderly dogs.

No. of bitstreams: 1 Lopes_PaulaJuliano_M.pdf: 1567108 bytes, checksum: dc73b9dfaf095d0ab3b2616cdc04dbd1 (MD5) Previous issue date: 2012 / Resumo: O transplante de fígado é um procedimento complexo que interfere em múltiplas funções do organismo podendo ocorrer complicações de diversas dimensões. Estudos revelam porcentagens variadas de complicações do sistema nervoso entre 8 - 47% dos casos e podem incluir encefalopatia, problemas cerebrovasculares, infecções e neurotoxicidade induzida por imunossupressores, sendo que a maioria destes casos ocorre na primeira semana de pós-operatório.. O objetivo do estudo foi verificar a relação entre o valor de magnésio sérico e o desenvolvimento de encefalopatia no período imediato ao transplante de fígado. Para realizar a pesquisa, foram coletados dados dos pacientes e doadores presentes em prontuários médicos de pacientes que tenham sido submetidos a transplante de fígado nos anos de 2007 a 2009. Os valores dos níveis de magnésio sérico dos sete primeiros dias de internação foram comparados com a referência laboratorial presente nos resultados revelados pelo laboratório do Hospital de Clínicas da Unicamp. O critério de West Haven foi usado para classificar se o paciente apresentava ou não encefalopatia hepática. Verificou-se que apenas o valor do magnésio no pós transplante foi o risco para que ocorresse a encefalopatia hepática (p = 0.0489). Quanto menor o valor do nível de magnésio sérico maior foi o risco de ocorrência de encefalopatia hepática (RR = 3.718; IC95% : 1.001-13.699). Como conclusão verificou-se a importância da hipomagnesemia como fator preditivo do aumento do risco de aparecimento da encefalopatia hepática no pós transplante imediato de fígado / Abstract: Liver transplantation is a complex procedure that interferes in multiple body functions and complications can occur in several dimensions. Studies have shown varying percentages of the nervous system complications from 8 to 47% of cases and may include encephalopathy, cerebrovascular problems, infections and neurotoxicity induced by immunosuppressive drugs, with the majority of these cases occurs in the first week after surgery. The objective was verify the correlation between the level of serum magnesium and the development of encephalopathy in the immediate post transplant period. To conduct the survey, the donor's and receptor's data from patients submitted to liver transplantation were collected in the medical transplant patients' records from 2007 to 2009. The levels of serum magnesium to in the first seven days of hospitalization were compared with the reference laboratory results by the Clinical Hospital of Unicamp. The West Haven criteria was used to classified if the patient have or not hepatic encephalopathy. It was found that only the levels of serum magnesium in post transplant was the risk for hepatic encephalopathy occurrence (p = 0.0489). The lower value of magnesium increased the risk of hepatic encephalopathy (RR=3.718; IC95% : 1.001- 13.699). In conclusion, we verified the importance of hypomagnesemia as predictive factor for hepatic encephalopathy increasing after liver transplantation / Mestrado / Fisiopatologia Cirúrgica / Mestra em Ciências

Patienters upplevelser av postoperativ smärta : en litteratrustudie

Wicksell-Jansson, Monica January 2018 (has links)
Sammanfattning   Bakgrund: Personer som ska genomgå en operation räknar med att ha smärta efteråt, så kallad postoperativ smärta. Hur stark smärtan upplevs beror bland annat på patientens erfarenhet av smärta. Smärta är en upplevelse som bara kan beskrivas av personen som har den. Kunskapen i smärta och smärthantering inom sjukvården har genom åren ökat, men patienterna uppger fortsatt att deras smärta är hög. Det ingår i sjuksköterskans arbetsuppgifter att bemöta och behandla smärtan för att minska patientens lidande. Syfte: Syftet med litteraturstudien var att beskriva patienters upplevelser av postoperativ smärta samt att beskriva de etiska aspekterna i de utvalda artiklarna. Metod: En beskrivande litteraturstudie med kvalitativ ansats. Databaserna PubMed och Cinahl användes för att söka de vetenskapliga artiklarna till studien. Åtta kvalitativa vetenskapliga artiklar utgjorde grunden för studiens resultat del. Huvudresultat: Analysen resulterade i 6 teman; ”Smärtan tar olika uttryck”, ”Finner egna sätt för att lindra smärtan”, ”Vill att bli tagen på allvar av vårdpersonalen”, ”Oro över att ta för mycket smärtstillande” ”Vill inte uppfattas som besvärlig” samt ”Viktigt med information om smärta” Slutsatser: Smärta är högst individuell och ska behandlas därefter. För att tillgodose patientens behov bättre vid smärta behöver sjuksköterskan mer kunskap om smärthantering, vilket då kan leda till större förståelse. När patienterna tilläts vara delaktiga i sin vård uppfattades det som något som påverkade deras tillfrisknande positivt. / Abstract   Background: People undergoing surgery are expected to have pain afterwards, so called postoperative pain. Hov strong the pain is experienced depends, among outher things, on the patient´s experience of pain. Pain is an experience that only can be described by the person who has it. Knowledge in pain and pain management has increased over the years, but patients still indicate that their pain is high. It is a part of the nurses duties to respond to and treat with the pain to reduce the patients suffering. Purpose: The aim with the literaturstudy was to describe patients experiences of postoperative pain. The aim was also to describe the ethical aspects in the selected articels. Method: A describtive literature study with qualitative approach. The databases PubMed and Cinahl was used to search for the scientific articels. Eight qualitative scientific articels formed the basis for the study result. Finding: The analyses resulted in 6 themes; ”The pain takes many forms”, ”Finds your own way to relieve the pain”, ”Wants to be taken seriously by health professionals”, ”Concern about too much pain medication”, ”Do not want to be perceived as troublesome” and ”Important with information about pain”. Conclution: Pain is highly individual and should be treated accordingly. To better meet the patients needs at pain nurses need more knowledge about painmanagement, which can leed to greater understanding. When the patient were allowed to be involved in their care it was perceived as something that affected their recovery positively.

Outcome of total Achilles tendon rupture repair, with special reference to suture materials and postoperative treatment

Kangas, J. (Jarmo) 24 April 2007 (has links)
Abstract The purposes of the present research were to compare the outcome after Achilles tendon rupture repair in two postoperative regimens, to compare Achilles tendon elongation in two postoperative treatment methods, to compare the effects of two postoperative methods on motor performance aspects such as simple reaction time, choice reaction time, speed of movement, foot tapping speed and coordination, to test the mechanical properties of the recently developed poly-L/D-lactide (PLDLA) sutures and Maxon® sutures when implanted in the Achilles tendons of rabbits, and to study the histological tissue reactions and biodegradation of these sutures under the same conditions. Isokinetic calf muscle strength scores at the last control check-up were excellent in 56% of the patients in the early motion group, good in 32%, fair in 8%, and poor in 4%, whereas the scores in the cast group were excellent in 29% of cases, good in 50% and fair in 21%. The ankle performance scores were excellent or good in 88% of the patients in the early motion group, fair in 4% and poor in 8%, whereas the scores in the cast group were excellent or good in 92% of cases and fair in 8%. No significant differences were seen between the two groups at 3 months and at the last control checkups with regard to pain, stiffness, subjective calf muscle weakness, footwear restrictions, range of ankle motion, isokinetic calf muscle strength or overall outcome. The complications included 1 re-rupture in the early motion group and 1 deep infection and 2 re-ruptures in the cast group. AT elongation occurred in both groups, but was somewhat less marked in the early motion group. The AT elongation curves rose at first and then fell slowly in both groups. The patients who had less AT elongation achieved a better clinical outcome. AT elongation did not correlate significantly with age, body mass index or isokinetic peak torques. The recovery of motor performance functions such as simple reaction time, choice reaction time, speed of movement, foot tapping speed and coordination did not depend on the two postoperative regimens. The motor functions of the operated leg had obviously recovered to the level of the non-operated leg 12 weeks after the operation. Sutures made of PLDLA were used successfully for Achilles tendon repair in rabbits. There was no significant difference between the in vitro and in vivo tensile strength retention of the sutures. By comparison with Maxon®, PLDLA was found to have a lower initial tensile strength but more prolonged strength retention. The breaking strength values of the Achilles tendons repaired with sutures of these types were not significantly different at 6 weeks. Intratendinous PLDLA sutures formed a thinner fibrous capsule during the 12-week follow-up period than did Maxon® sutures of the same diameter. The suture materials had not been totally absorbed by 12 weeks.

MRI of intracranial tumours in adults:oedema-attenuated inversion recovery MR sequence in low-field MRI, diffusion-weighted MRI and BOLD fMRI

Kokkonen, S.-M. (Salla-Maarit) 03 November 2009 (has links)
Abstract The goal of this study was to explore preoperative evaluation of patients with intracranial tumours using magnetic resonance imaging (MRI) methods: oedema-attenuated inversion recovery (EDAIR) sequence in low-field MRI, and diffusion-weighted imaging (DWI) and resting-state functional MRI (fMRI) in high-field MRI. The aim was also to increase our knowledge about the effects of brain surgery on eloquent brain cortices using new MRI techniques. The total number of patients in these studies was 50 (24 women). Enhancement of the tumour in ten patients after intravenous administration of gadolinium-based contrast agent in low-field MRI was examined with a new sequence, EDAIR, and compared with more conventionally used partial saturation spin echo sequences. EDAIR may facilitate the perception of small enhancing lesions and is valuable in low-field imaging, where T1-based contrast is inferior to high-field imaging. DWI was performed on 25 patients in order to evaluate the potential of this imaging method to assist in differential diagnosis of intracranial tumours. It was shown that apparent diffusion coefficient values of the tumour and peritumoural oedema produced by DWI were different in benign and malignant tumours. Resting-state blood oxygen level-dependent (BOLD) fMRI was performed on eight patients and ten healthy volunteers to examine if functional sensorimotor areas in the brain could be determined without any task-related activations. It was shown that intracranial tumours do not appear to hamper visualization of the sensorimotor area in resting-state BOLD fMRI when independent component analysis is performed, and this method may be used in preoperative imaging when activation studies cannot be performed. Conventional BOLD fMRI with motor and auditory stimuli was used with seven patients as the effect of brain surgery was studied. The results suggest that resection of a tumour with preoperative oedema probably decreases pressure on the brain and makes the functional cortex transiently more easily detectable in BOLD fMRI. In conclusion, the MRI imaging methods used in this study can give valuable additional information about the tumour, specifically for preoperative imaging and planning for surgery.

Pain relief after joint surgery:a clinical study

Laurila née Kostamovaara, P. (Päivi) 11 October 2002 (has links)
Abstract Excessive pain after surgery causes many kinds of endocrine, metabolic and inflammatory responses, which may increase postoperative morbidity and mortality - especially among elderly patients. This study evaluated the effect of peripheral and central pain relief techniques after joint surgery. Intravenously administered doses of 100 mg, 200 mg and 300 mg of ketoprofen decreased the requirement for opioid (fentanyl) in a dose-dependent manner by 38%, 45% and 53%, respectively, compared with a placebo, without any noticeable ceiling-effect, when administered after hip and knee arthroplasty. Patients receiving a 300 mg dose of ketoprofen had significantly lower postoperative pain scores than those receiving a placebo. There were no significant differences in incidences of nausea and vomiting, or in the amount of bleeding between the ketoprofen and placebo groups. Intravenous doses of 200 mg of ketoprofen, 150 mg of diclofenac, and 120 mg of ketorolac produced similar postoperative pain scores and requirement for opioid (fentanyl) with no intergroup differences in the incidence of nausea and vomiting and in the amount of bleeding, when administered after hip arthroplasty. The addition of ropivacaine, 1 mg·ml-1, did not decrease the requirement for epidural fentanyl administered via a patient-controlled analgesia device for postoperative pain relief after hip arthroplasty. Both drug infusions provided effective pain relief. The most common adverse effect was pruritus, which occurred in a similar number of patients in both groups. An interscalene brachial plexus block with ropivacaine decreased the dose of PCA-delivered oxycodone by 78% after arthroscopic shoulder surgery while subacromial bursa blockade with ropivacaine decreased it by only 11 % compared to a placebo during the 20 hour study period. Postoperative pain scores were significantly lowest with a interscalene brachial plexus block.
