Neuraxial anesthesia versus general anesthesia for urological surgery: systematic review / Anestesia neuroaxial versus anestesia geral para cirurgias urológicas: revisão sistemática

CONTEXT AND OBJECTIVE Choosing the best anesthetic technique for urological surgery with the aim of mortality reduction remains controversial. The objective here was to compare the effectiveness and safety of neuraxial anesthesia versus general anesthesia for urological surgery. DESIGN AND SETTING Systematic review, Universidade Federal de Alagoas. METHODS We searched the Cochrane Central Register of Controlled Trials in the Cochrane Library (Issue 10, 2012), Medline via PubMed (1966 to October 2012), Lilacs (1982 to October 2012), SciELO and EMBASE (1974 to October 2012). The reference lists of the studies included and of one systematic review in the same field were also analyzed. The studies included were randomized controlled trials (RCT) that analyzed neuraxial anesthesia and general anesthesia for urological surgery. RESULTS The titles and abstracts of 2720 articles were analyzed. Among these, 16 studies were identified and 11 fulfilled the inclusion criteria. One RCT was published twice. The study validity was: Jadad score > 3 in one RCT; seven RCTs with unclear risk of bias as the most common response; and five RCTs not fulfilling half of the Delphi list items. The frequency of mortality was not significant between study groups in three RCTs. Meta-analysis was not performed. CONCLUSION At the moment, the evidence available cannot prove that neuraxial anesthesia is more effective and safer than general anesthesia for urological surgery. There were insufficient data to pool the results relating to mortality, stroke, myocardial infarction, length of hospitalization, quality of life, degree of satisfaction, postoperative cognitive dysfunction and blood transfusion requirements. .

CONTEXTO E OBJETIVO A escolha da melhor técnica anestésica para cirurgias urológicas para reduzir mortalidade permanece controversa. O objetivo foi comparar a efetividade e segurança da anestesia neuroaxial versus anestesia geral para cirurgias urológicas. TIPO DE ESTUDO E LOCAL Revisão sistemática, Universidade Federal de Alagoas. MÉTODO Fizemos a busca em Cochrane Central Register of Controlled Trials na Cochrane Library (2012, volume 10), Medline via PubMed (1966 até outubro de 2012), Lilacs (1982 até outubro de 2012), SciELO e EMBASE (1974 até outubro de 2012). As listas de referências dos estudos incluídos e de uma revisão sistemática em urologia também foram analisadas. Os estudos incluídos foram ensaios clínicos randomizados (ECR) que analisaram as anestesias neuroaxial e geral para cirurgias urológicas. RESULTADOS Os títulos e resumos de 2.720 artigos foram analisados. Entre eles, 16 estudos foram identificados e 11 preencheram os critérios de inclusão. Um ECR foi publicado duas vezes. A validade dos estudos foi: escore de Jadad > 3 em um ECR; sete ECRs com indeterminado risco de viés como a resposta mais comum; cinco ECR sem preenchimento da metade dos itens da lista de Delphi. A frequência de mortalidade não foi significante entre os grupos de estudo em três ECR. A metanálise não foi realizada. CONCLUSÃO Até o momento, as evidências disponíveis não puderam provar que a anestesia neuroaxial seja mais efetiva e segura do que a anestesia geral para cirurgias urológicas. Não houve dados suficientes para reunir os resultados de mortalidade, infarto cerebral, infarto do miocárdio, duração de internação hospitalar, qualidade de vida, grau ...

Stress response and hemodynamic change during laparoscopic cholecystectomy under general anesthesia and general-epidural combined anesthesia / 中国现代普通外科进展

Objectives:To observe the stress response and hemodynamic change during laparoscopic cholecystectomy(LC) under general anesthesia and general-epidural combined anesthesia.Methods:28 patients of LC were divided into general anesthesia group(G group n=14) and general-epidural anesthesia group(GE group n=14) randomly.The HR、SBP、MAP,plasma concentration of epinephrine(E),norepinepherine(NE),blood glucose、cortisol,PaCO2 and pH were measured before and after peritoneal insufflation of CO2.Results:The HR,SBP and MAP were increased significantly in group G than those in group GE(P

Hemodynamic changes during laparoscopic cholecystectomy under different anesthesia / 中华麻醉学杂志

To observe the hemodynamics changes of patients undergoing laparoscopic cholecystectomy under epidural or general anesthesia. Method: 25 patients were divided into two groups: general(GA, n=11)and epidural (EA, n=14) anesthesia groups. Hemodynamic parameters (HR, MAP, CVP, PCWP, PAP, CO, CI, SVR, PVR) were measured with Swan-Ganz technique after the patients being placed to rT position,CO2 being insufflated into peritoneal cavity, and at the end of operation. Result: 1. In the EA group, CVP reduced significantly after rT position placed, SV, CO, MAP and HR reduced significanty after peritoneal insufflation,but still within normal range. 2. In the GA group, CVP, SV, CO were significant ly reduced after rT position placed; After peritoneal insufflation, all parametere were significantly increased except SV had no significant change. Conclusion:Epidural anesthesia can be safely applied to the ASA Ⅰ-Ⅱ grade patients undergoing laparoscopic cbolecystectomy.
