HEMODYNAMIC CHANGES DURING LAPAROSCOPIC CHOLECYSTECTOMY UNDER EPIDURAL ANESTHESIA

Objective : To observed the hemodynamic changes of laparoscopic chole-cystectomy (LC) patients under epidural anesthesia comparing with those under general anesthesia, and to evaluated the advantages and the disadvantages of them. Methods : Twenty-five patients with ASA-Ⅰ - Ⅱgrade were divided into two groups: genera I anesthesia group(n = 11)and epidurai anesthesia group(n = 14).Hemodynamic parameters(HR, MAP,CVP,PAP, CP and computed Cl, SVR, PVR) were monitored at the time from after anesthesia to the end of LC. Results : ①In both groups, CVP reduced significantly after revered position;②In the epidurai anesthesia group, HR.MAP, CO, SV reduced significantly after pneumoperitoneum,but still within normal range;③In the general anesthesia group, after pneumoperitoneum, all parameters were significantly increased except SV had no significant change. Conclusion : Epidural anesthesia can be safely applied to the ASA-Ⅰ- Ⅱgrade patients undergoing LC as conventional anesthesia.
