Abstract：Objective To study the effects of repiratory frequency and tidal volume for CO2 pneumoperitoneum on respiratory system and gastric intramucosal pH of aged patients during laparoscopic cholecystectomy.Methods Forty-two patients were divided into group A(f=12,Vt=9ml/kg,n=22) and group B(f=14,Vt=7ml/kg,n=20).PPEAK, PETCO2 and pHi were monitored before pneumoperitoneum (T1) 20min after pneumoperitoneum (T2) and relieving pneumoperitoneum (T3) respectively.Results PPEAK,PETCO2 at T2 were significantly higher than that at T1 in the same groups 公式. pHi of B group at T2 was significantly lower than that at T1(P＜0.05).There were significant difference of T2 indexes in group A compared with group B(P＜0.05).ConclusionThe method of proper frequency rate and tidal volume in CO2 pneumoperitoneum may act positively for respiratory system and pHi of aged patients during laparoscopic cholecystectomy .
