RESUMEN
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.
