ABSTRACT Open cholecystectomy is associated with characteristic changes in pulmonary function showing a restrictive pattern. Laparoscopic cholecystectomy without opening of the peritoneal cavity could be an alternative in reducing postoperative respiratory dysfunction. Having given their informed consent, 13 healthy ASA1 patients (age: 41 +/- 18 yrs) undergoing laparoscopic cholecystectomy were enrolled in this study, in order to assess their postoperative pulmonary function tests (forced vital capacity [FRC], forced expiratory volume [FEV1], functional residual capacity [FRC]) before operation (T0) and 4 h (T4), 24 h (T24), 48 h (T48) after surgery. Anaesthesia technique was the same associating propofol-atracurium-fentanyl, 50% N2O/O2. Ventilation was adapted to maintain end-tidal carbon dioxide pressure up to 30-35 mmHg. Postoperative analgesic regimen consisted of paracetamol-ketoprofen. Mean length of surgery was 84 +/- 15 min; mean duration of anaesthesia was 110 +/- 24 min. An immediate and harmonious restrictive breathing pattern developed postoperatively. Postoperative FVC measured 65% (T4), 63% (T24), 72% (T48) of preoperative function (p < 0.025); postoperative FEV1 measured respectively 60, 66 and 75% of preoperative function (p > 0.001), without change in FEV1/CV and FRC; a significant hypoxia occurred (T0: 86 mmHg, T4: 80 mmHg, T24: 75 mmHg, T48: 81 mmHg [p < 0.05]). Laparoscopic cholecystectomy resulted in less postoperative respiratory dysfunction than conventional cholecystectomy, as previously reported; this restrictive pattern observed without changes in FRC was similar to that following lower abdominal surgery.

    ABSTRACT: OBJETIVO: Avaliar a função pulmonar pós-colecistectomias laparoscópicas e subcostais abertas. MÉTODOS: Tratou-se de um ensaio randomizado, onde se avaliaram espirometrias pós-operatórias de dois grupos, cada qual com 15 pacientes. O grupo GL foi submetido a colecistectomia laparoscópica. O grupo GA foi submetido a colecistectomia por via subcostal, por meio de mini-laparotomia e abreviado tempo anestésico-cirúrgico. As variáveis dos dois grupos foram comparadas entre si por meio da ANOVA. Entre um mesmo grupo, antes e depois das operações, utlizou-se do teste t-Student emparelhado. Um valor de p < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Todas as pacientes, dos dois grupos, apresentaram distúrbios ventilatórios restritivos pós-operatórios, com normalização espirométrica mais rápida nas pacientes operadas por laparoscopia. Grupos GL X GA, no pós-operatório imediato: Capacidade vital forçada (p < 0,001) e Volume Expiratório forçado em 1 segundo (p < 0,001). CONCLUSÕES: O prejuízo pós-operatório da função pulmonar foi significativamente menor nas colecistectomias laparoscópicas do que nas abertas, mesmo por meio de mini-laparotomia e abreviado tempo anestésico-cirúrgico.

    ABSTRACT: Laparoscopic surgery has advanced remarkably in recent years, resulting in reduced morbidity and shorter hospital stay compared with open surgery. Despite challenges from the expanding array of laparoscopic procedures performed with the use of pneumoperitoneum on increasingly sick patients, anesthesia has remained largely unchanged. At present, most laparoscopic operations are usually performed under general anesthesia, except for patients deemed "too sick" for general anesthesia. Recently, however, several large, retrospective studies questioned the widely held belief that general anesthesia is the best anesthetic method for laparoscopic surgery and suggested that regional anesthesia could also be a reasonable choice in certain settings. This narrative review is an attempt to critically summarize current evidence on regional anesthesia for laparoscopic surgery. Because most available data come from large, retrospective studies, large, rigorous, prospective clinical trials comparing regional vs. general anesthesia are needed to evaluate the true value of regional anesthesia in laparoscopic surgery.
