摘　　要：目的为了提高婴幼儿麻醉安全性,探讨压力控制呼吸复合气管导管端持续供氧在预防婴幼儿麻醉二氧化碳蓄积中的应用价值。方法采用随机数字表法从本院2018年5月~2019年6月需行气管插管全麻手术治疗的婴幼儿中选取60例作为研究对象,通过奇、偶数法将其平均分组,其中在常规全身麻醉插管后用普通麻醉机行压力控制呼吸(压力12~15cm H2O,频率20~25次/min)复合气管导管端持续以2L/min氧流量供氧的30例患儿设为观察组,在常规全身麻醉插管后用普通麻醉机行压力控制呼吸(压力12~15cm H2O,频率20~25次/min)的30例患儿设为对照组,两组均于麻醉后30min查动脉血气一次,比较两组二氧化碳蓄积占比及术中生命体征变化的差异。结果研究数据显示,观察组患儿的二氧化碳蓄积占比(6.7%)明显低于对照组(50.0%),组间比较差异有统计学意义(P<0.05);麻醉后和抽血气时观察组和对照组患儿各生命体征[心率(HR)、平均动脉压(MAP)]比较差异无统计学意义(P>0.05)。结论婴幼儿麻醉过程中采用压力控制呼吸复合气管导管端持续供氧,能够减少二氧化碳蓄积,效果显著,值得推广应用。Objective To explore the application value of continuous oxygen supply of pressure-controlled respiratory combined with tracheal intubation to prevent carbon dioxide accumulation in infants anesthesia Methods A total of 60 infants who needed tracheal intubation and general anesthesia surgery from May 2018 to June 2019 in our hospital were selected by using random number table method,and were evenly grouped by odd and even number.The observation group(n=30)was given continuous oxygen supply(2 L/min)of pressure-controlled respiratory using general anesthesia machine(pressure 12-15 cm H2 O,frequency 20-25 beats/min)combined with tracheal intubation after intubation under general anesthesia,while the control group(n=30)was given pressure-controlled respiratory using general anesthesia machine(pressure 12-15 cm H2 O,frequency 20-25 beats/min).The arterial blood gas was checked 30 minutes after anesthesia,and the difference in the proportion of carbon dioxide accumulation and the changes in vital signs during the operation was compared between the two groups.Results The results showed that the proportion of carbon dioxide accumulation in the observation group(6.7%)was significantly lower than 50.0%in the control group,and the difference were statistically significant(P<0.05);there was no significant difference in the vital signs[heart rate(HR),mean arterial pressure(MAP)]after anesthesia and when blood was drawn between the two groups(P>0.05).Conclusion The application of continuous oxygen supply of pressure-controlled respiratory combined with tracheal intubation in infants anesthesia can reduce the accumulation of carbon dioxide,which has a remarkable effect and is worthy of popularization and application.
