<p>Uvod:Apendicitis je oboljenje, koje se najče&scaron;će javlja u dečjem uzrastu. Poslednjih godina se laparoskopska apendektomija sprovodi sve če&scaron;će u ovom uzrastu, međutim ne postoji jasan konsenzus o optimalnom izboru anestetika za održavanje op&scaron;te anestezije u toku ove hirur&scaron;ke metode u dečjem uzrastu. Cilj istraživanja: Utvrditi uticaj vrste anestezije i vrste hirur&scaron;ke procedure na odgovor organizma na hirur&scaron;ki stres tokom operacije crvuljka. Metodologija: Klinički prospektivno istraživanje je sprovedeno na Klinici za dečiju hirurgiju, na Institutu za zdravstvenu za&scaron;titu dece i omladine Vojvodine. Istraživanjem je obuhvaćeno 120 dece, uzrasta od 7 do 17 godina, bez postojećih komorbiditeta, koji su operisani zbog zapaljenja crvuljka. U zavisnosti od vrste operativnog zahvata i vrste primenjene anestezije deca su podeljena u četiri grupe bolesnika. Kod sve četiri ispitivane grupe uzimana je venska i kapilarna krv, nekoliko minuta nakon uvoda u anesteziju, u momentu vađenja crvuljka iz trbuha i 12 časova nakon kraja hirur&scaron;ke intervencije. Laboratorijski su određeni markeri oksidativnog stresa (TBARS), metaboličkog odgovora na hirur&scaron;ki stres (laktat, glikemija), inflamatornog odgovora organizma (IL-6, leukociti), gasne analize, parametri oksigenacije i ventilacije, i hemodinamski parametri ispitanika. Rezultati:U istraživanju je dobijen rezultat da je zapaljenje crvuljka oboljenje koje se če&scaron;će javlja kod dečaka. Tokom apendektomije u dečjem uzrastu, sevofluran je bolje kontrolisao arterijsku tenziju, dok na srčanu frekvencu vrsta anestezije nije imala uticaja. Sevofluran je anestetik tokom čije primene je manji inflamatorni odgovor tokom laparoskospske apendektomije. Propofol deluje suprimirajuće na oksidativni stres, ali nije nađena statistička značajnost u odnosu na vrednosti dobijene analizom uticaja sevoflurana na parametre oksidativnog stresa. Zaključak: Laparoskopska apendektomija u odnosu na laparotomiju nije praćena većim stepenom hirur&scaron;kog stresa, a sevofluran je anestetik koji tokom anestezije za laparoskopsku apendektomiju u dečijem uzrastu daje bolju kontrolu kliničkog, metaboličkog i inflamatornog odgovora.</p> / <p>Introduction: Appendicitis is a disease which appears most commonly in children. In recent years appendectomy in children is performed by laparoscopy, but there is no consensus yet on the optimal choice of anesthetics during general anesthesia for this procedure. Aim: To determine the influence of type of anesthesia and type of surgical procedure for appendectomy, on surgical stress in children. Methodology: A prospective clinical trial in Clinic of pediatric surgery in Novi Sad, Vojvodina. The study included 120 children aged from 7 to 17 years, with no commorbidities, who underwent appendectomy. Children were divided in four groups based on the type of anesthesia and type of surgery they received. In all participants, venous and capillary blood was sampled for analyzis 10 minutes after induction of anesthesia, at the moment of appendix removal and 12 hours after the procedure. The laboratory analysis included markers of oxidative stress (TBARS), metabolic response to surgical stress (lactate, blood glucose), inflammatory response (IL-6, leucocites), bloodgas analyses, parameters of oxygentation and ventilation and haemodynamic parameters of the participants. Results: In the study appendicitis was more common in boys. During laparoscopic appendectomy sevoflurane controlled better the blood pressure, but not the heart rate. Sevoflurane maintained a better control of parameters of the inflammatory response. Propofol decreased the oxidative stress, but there was no statistical difference compared to the effects of sevoflurane on oxidative stress. Conclusion: Laparoscopic appendectomy shoved no difference in the level of surgical stress compared to laparotomy, and sevoflurane appeared as an anaesthetic which had a better control of the metabolic, clinical and inflammatory response.</p>

Introdução: A resposta inflamatória sistêmica após cirurgia cardíaca está relacionada com aumento dos marcadores de lesão cerebral e o desenvolvimento de disfunção cognitiva pós-operatória (DCPO). O objetivo deste estudo foi avaliar a potencial associação entre DCPO e os níveis séricos de proteína S100beta e enolase específica de neurônio (NSE) após cirurgia de revascularização do miocárdio (RM) com circulação extracorpórea (CEC). Métodos: Foram investigados 73 pacientes submetidos à RM com CEC. A função cognitiva foi avaliada por psicólogas no pré-operatório e nos 3º, 7º, 21º, 90º e 180º dias após a cirurgia, utilizando-se testes neurocognitivos específicos para o reconhecimento de déficits de atenção, memória, função executiva e linguagem. Os níveis séricos de proteína S100beta e NSE foram medidos no pré-operatório, após a indução da anestesia, ao final da cirurgia e seis e 24 horas após a cirurgia. Para se avaliar a associação entre DCPO e os níveis séricos de proteína S100beta e NSE, utilizou-se ANOVA e ANOVA com medidas repetidas. As diferenças encontradas foram analisadas pela comparação múltipla de Tukey. Os resultados foram significantes quando p < 0,05. Resultados: DCPO foi observada em 63,1% dos pacientes após 21 dias e em 21,7% após seis meses da cirurgia. Na primeira semana após a cirurgia, 46,6% dos pacientes apresentaram delirium pósoperatório. Os maiores níveis séricos de proteína S100beta (1,8 ng/mL) e NSE (18,2 ng/mL) foram vistos no final da cirurgia e seis horas após a cirurgia, respectivamente. No entanto, não foi observada significante associação entre DCPO e aumento dos níveis séricos dos marcadores de lesão cerebral. Conclusões: O presente estudo observou uma elevada prevalência de DCPO. Adicionalmente, detectou-se um aumento dos níveis séricos de proteína S100beta e NSE no pós-operatório. Contudo, embora RM com CEC esteja significativamente relacionada a DCPO e níveis séricos elevados de proteína S100beta e NSE, o aumento dos níveis destes marcadores de lesão cerebral não foi associado à DCPO / Background: Systemic inflammatory response after cardiac surgery is associated with increased brain injury markers and development of postoperative cognitive dysfunction (POCD). The aim of this study was to evaluate the association between POCD and serum levels S100beta protein and neuron-specific enolase (NSE) after coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB). Methods: 73 patients undergoing CABG surgery with CPB were investigated. Cognitive function was assessed by psychologists preoperatively and at 3, 7, 21, 90 and 180 days after surgery, using neurocognitive tests for specific recognition deficits in attention, memory, executive function and language. Serum levels S100beta protein and NSE were measured preoperatively, after induction of anesthesia, in the end of surgery, and 6 and 24 hours after surgery. Association between POCD and serum levels S100beta protein and NSE was assessed with ANOVA and ANOVA with repeated measurements. Differences were analyzed by Tukey\'s multiple comparison. Results were significant at p <0.05. Results: The mean age of patients was 61.8 ± 9.1 years. POCD was observed in 63.1% of patients after 21 days and 21.7% after 6 months of surgery. Postoperative delirium was seen in 46.6% of patients in the first week after surgery. The highest serum levels of S100beta protein (1.8 ng/mL) and NSE (18.2 ng/mL) were seen at the end of surgery and 6 hours after surgery, respectively. However, this study not observed a significant association between POCD and increased serum levels brain injury markers. Conclusions: The present study observed a high prevalence of POCD. Additionally, serum levels S100beta protein and NSE increased postoperatively. However, while CABG surgery with CPB is significantly related to POCD and elevated serum levels S100beta protein and NSE, the increased levels of such brain injury markers was not associated with POCD
