摘　　要：目的:观察CO2气腹对老年患者胃粘膜pH值的影响.方法:择期腹腔镜胆囊切除术40例,老年患者(≥65岁)、≤55岁患者各20例,分别于气腹前(T1)、气腹后30min(T2)、气腹结束后30min(T3)监测PaCO2、pHi、P(i-a)CO2、PETCO2.结果:老年组T2、T3时点pHi降低,PaCO2、P(i-a)CO2、PETCO2升高,与T1相比差异有显著性;与成年组T2、T3时点各指标相比差异也有显著性.结论:CO2气腹可使老年患者胃粘膜pH值(pHi)明显下降.Objective:To observe the effect of CO_2 pneumoperitoneum on gastric intramucosal pH(pHi) of aged patients. Methods: 40 patients being given laparoscopic cholecystectomy were divided into elderly group(age≥65,n=20) and adult group(age≤55,n=20). pHi,PaCO_2,P(i-a)CO_2,PETCO_2 were monitored before pneumoperitoneum(T_1)30min after pneumoperitoneum(T_2) and 30min after relieving pneumoperitoneum(T_3)respectively. Results: pHi of elderly group at T_2,T_3 was significantly lower than that at T_1, Reversely, PaCO_2,P(i-a)CO_2,P_ ETCO_2 at T_2,T_3 were significantly higher than that at T_1 . There were significant difference of T_2,T_3 indexes in elderly group compared with those in adult group. Conclusion:CO_2 pneumoperitoneum may decrease pHi of aged patients during laparoscopic cholecystectomy.
