【摘要】：目的:比较肥胖病人全麻分别应用PCV和VCV通气模式,对动脉氧合的影响。方法:选择40例全麻手术的肥胖患者,随机分为压力控制通气组(PCV)和容量控制通气组(VCV),每组20例。呼气末二氧化碳分压维持在35-45mm Hg之间。术前30分钟(T0),手术开始30分钟(T1),手术开始60分钟(T2),手术结束(T3)拔管后30分钟(T4),进行血气分析。监测和计算血流动力学指标。结果:1、两组病人一般情况差别无统计学意义(p0.05)2、与VCV组比较,PCV组的Pa O2、OI在T1、T2、T3均高于VCV组(p0.05)。结论:和VCV比较,PCV在肥胖患者的麻醉中改善通气血流比例,促进气体交换。
[Abstract]:Objective: to compare the effects of PCV and VCV ventilation modes on arterial oxygenation in obese patients under general anesthesia. They were randomly divided into pressure control ventilation group (PCV) and volume controlled ventilation group (VCVV), 20 cases in each group. The end expiratory partial pressure of carbon dioxide was kept between 35 and 45 mm Hg. 30 minutes before operation, 30 minutes before operation, 30 minutes before operation, 30 minutes before operation, 60 minutes after operation, T2 was given, and the operation ended with T3. 30 minutes after extubation, blood gas was analyzed, blood gas was monitored and hemodynamic indexes were calculated. Results: there was no significant difference in general conditions between the two groups (P 0.05). Compared with VCV group, Pa O _ 2O _ (2) O _ (2) O _ (2) O _ (2) I in T _ (1) T _ (2) T _ (2) T _ (3) was higher than that in VCV group (P 0.05). Conclusion:. To compare the effect of PCV on improving the ventilatory blood flow ratio in obese patients during anesthesia. Promote gas exchange.
