目的:比较不同通气方案救治儿科重症监护室(PICU)急性呼吸窘迫综合征(ARDS)患儿的效果。方法:抽取2018年3月至2019年7月焦作市妇幼保健院PICU收治86例ARDS患儿，依据随机数字表法分为对照组和观察组，每组43例。两组均接受常规治疗，对照组给予常频机械通气(CMV)，观察组给予高频振荡通气(HFOV)。记录对比两组呼吸机使用时间、氧疗时间和住院时间等指标；检测并比较两组治疗前后12、24、72 h的血气指标；检测并对比两组的氧合功能；记录对比两组并发症发生情况。结果:观察组呼吸机使用时间、氧疗时间和住院时间均短于对照组(n P<0.05)；两组治疗后12、24、48 h的酸碱度(pH)、动脉氧分压(PaOn 2)水平均较治疗前升高，动脉二氧化碳分压(PaCOn 2)水平较治疗前降低，且观察组各时点的pH、PaOn 2水平均高于对照组，PaCOn 2水平低于对照组(n P<0.05)；两组治疗后12、24、48 h的氧合指数(OI)、呼吸指数(RI)水平均较治疗前降低，且观察组各时点的OI、RI水平均低于对照组(n P0.05)。n 结论:相比于CMV，HFOV救治PICU ARDS患儿的整体获益更好，其可有效改善患儿血气和氧合功能，促进患儿呼吸功能及病情恢复，且不会增加并发症风险，安全可靠。“,”Objective:To compare the effects of different ventilation schemes in the treatment of children with acute respiratory distress syndrome (ARDS) in the pediatric intensive care unit (PICU).Methods:A total of 86 patients with ARDS admitted to PICU of Jiaozuo Maternal and Child Health Hospital from March 2018 to July 2019 were selected. According to the random number table method, they were divided into control group and observation group, with 43 cases in each group. Both groups were received conventional treatment, the control group was given conventional mechanical ventilation (CMV), and the observation group was given high frequency oscillatory ventilation (HFOV). The ventilator use time, oxygen therapy time and hospital stay of the two groups was recorded and compared; the blood gas indexes before treatment and 12, 24, 72 hours after treatment was detected and compared. the oxygenation function of the two groups was detected and compared; the complications of the two groups were recorded and compared.Results:The ventilator use time, oxygen therapy time and hospital stay in the observation group were shorter than those in the control groupt (n P0.05).n Conclusions:Compared with CMV, HFOV has better overall benefits in treating ARDS children in PICU. It can effectively improve the blood gas and oxygenation function of children, promote the recovery of respiratory function and illness, and will not increase the risk of complications, and is safe and reliable.
