Effects of pneumoperitoneal pressure on analepsia character in laparoscopic cholecystectomy

Objective To investigate the effects of different pneumoperitoneal pressure on analepsia character in laparoscopic cholecystectomy.Methods Forty patients with cholelithiasis or gallbladder polpy,American Society of Anesthesiologists(ASA)gradeⅠ-Ⅱ,undergoing laparoscopic cholecystectomy,were randomly allocated into one of two groups:group A and B.patients in the two groups.Pneumoperitoneal pressure was controlled at 12 mm Hg in group A,and 15 mm Hg in group B.Vital sign and recovery profiles and conscious state after operation were compared.Results In the two groups,MAP and SpO2 were higher and HR were stepped down after CO2 insufflation 30 min in group A(P0.05).The eyes opening,the time fromstopping administration of anaesthetics until recovery breath,tracheal extubation,recovery of orientation(time,space)Mean arterial pressure,Aldrete score of 9 (or above) were short in group A than in group B(P0.05). The observer of assessment of alertness/sedation(OAAS)scores at 30 min and 60 min after extubatting tracheal was higher in group A than in group B(P0.05).And the verbral report score(VRS) at instant,10 min,30 min and 60 min after extubatting tracheal was higher in group A than in group B(P0.05).Conclusions 12 mm Hg pneumoperitoneal pressure in laparoscopic cholecystectomy is associated with better hemodynamics stability,less painful complications,and the recovery times are short.
