Effect of anesthesia, position,CO_2 pneumoperitoneum on hemodynamic changes and respiratory mechanics during laparoscopic cholecystectomy and laparoscopic gynecologic operation

objective To observe the effect of anesthesia、position、CO2 pneumoperitoneum of BP、HP、SpO2、PetCO2、airway pressure during laparoscopic cholecystectomy and laparoscopic gynecologic operation . Methods : ASA -Ⅱ patients undergoing laparoscopic cholecystectomy of laparoscopic gynecologic operation were selected in this study ,38 patients in each group. Anesthesia were maintained with propofol and isoflurane. The parameters of hemodynamic and respiratory mechanics were recorded before induction,shortly, 5 min after intubation ,3 min and 8 min after pneumoperitoneum and after deflation . Results Bp and HR decreased significantly at 5 min after intubation , compared with those before induction ( P 0.01) . BP 、 PetCO2、airway pressure at 3 min and 8 min after pneumoperitoneum increased significantly,compared with those at 5 min after intubation (P0. 01). Compared with laparoscopic cholecystectomy group, PetCO2,airway pressure in the laparoscopic gynecologic operation group increased significantly (P0.01) . Conclusions The changes of respiratory mechanics in the laparoscopic gynecologic operation group were significantly larger than laparoscopic cholecystectomy group, but the hemodynamic changes did not differ much in the two groups.
