摘　　要：目的:探讨不同面罩通气模式在小儿麻醉诱导期中的应用价值分析。方法:选取2019年12月-2021年2月在某院实施手术的150例患儿,采用简单随机分组将患儿分为手动控制通气组(A组)、压力控制通气组(PCV)(B组)、压力控制容量保证通气组(C组)各50例,分别于麻醉诱导前后,记录3组患儿在不同时间点的心率(HR)、呼吸频率(RR)、平均动脉压(MAP)和经皮动脉血氧饱和度(SPO_(2));记录3组患儿在自主呼吸消失后2min的气道峰压、平均气道压、呼吸频率、吸入潮气量、呼出潮气量等呼吸参数变化。结果:在T1的时候,3组患儿的HR、RR、MAP、SPO_(2)水平相比无显著差异(P>0.05),在T2、T3、T4时,B组、C组的HR、RR、MAP、SPO_(2)水平均显著低于A组(P<0.05);在自主呼吸消失后2min,B组、C组的气道峰压及平均气道压水平显著低于A组;吸入潮气量及呼出潮气量水平显著高于A组(P<0.05)。结论:三种面罩通气方式均可满足患儿的通气需要,但PCV和压力控制容量保证通气模式可降低患儿的气道峰压,有利于维持患儿呼吸频率的稳定性。Objective:To explore the application value of different mask ventilation modes in the induction period of pediatric anesthesia.Methods:A total of 150 children with surgery in a hospital from December 2019 to February 2021 were selected.According to simple random grouping method,they were divided into manual control ventilation group(group A),pressure control ventilation group(PCV)(group B)and pressure control volume guarantee ventilation group(group C),with 50 cases in each group.Before and after anesthesia induction,the heart rate(HR),respiration rate(RR),mean arterial pressure(MAP)and transcutaneous oxygen saturation(SPO2)at different time points,and the changes of respiratory parameters(peak airway pressure,mean airway pressure,respiratory rate,inspiratory tidal volume,delivered tidal volume)at 2 minutes after the disappearance of autonomous respiration were recorded.Results:At T1,there was no significant difference in levels of HR,RR,MAP and SPO_(2) among the three groups(P>0.05).At T2,T3 and T4,levels of HR,RR,MAP and SPO_(2) in group B and group C were significantly lower than those in group A(P<0.05).At 2 minutes after the disappearance of autonomous respiration,peak airway pressure and mean airway pressure in group B and group C were significantly lower than those in group A,while levels of inspiratory tidal volume and delivered tidal volume were significantly higher than those in group A(P<0.05).Conclusion:The three kinds of mask ventilation modes can meet ventilation demands of children.However,PCV and pressure control volume guarantee ventilation can reduce peak airway pressure,which is beneficial to maintain the stability of respiratory rate.
