机械通气患儿体位改变插入胃管临床观察

目的：探讨提高机械通气患儿插入胃管的成功率,减少因反复插管所致的并发症。方法：对60例机械通气患儿随机分为观察组30例和对照组30例,观察组采用抬高床头70度～80度,头正位插入胃管;对照组采用常规的去枕头后仰卧位的方法插入胃管。结果：对照组一次插管成功率为6.66%,观察组一次插管成功率为90%,经统计学分析,差异有显著性（P〈0.01）。结论：机械通气患儿改变常规的去枕头后仰位为抬高床头70度～80度头正位后一次插入胃管成功率明显提高。

Clinical observation on postural change for the insertion of gastric canal in children undergoing mechanical ventilation

Objective:In order to improve the successful rate of gastric canal insertion in children undergoing mechanical ventilation and reduce the complications caused by repeated intubation.Methods:60 patients undergoing mechanical ventilation were randomly divided into observation group and control group,with 30 cases in each group.Raising the the bed-head 70~80 degrees in a head orthophoria was used in the observation group for the insertion of gastric canal,while the control group with the conventional method to insert the gastric canal in a hypsokinesilying position without pillow.Results:The once successful rate of intubation was 90% in the observation group and 6.66% in the control group,with a significant statistical difference between them(P<0.01).Conclusion:The conventional method called"Pillow-removed hypsokinesis position" is changed over to the head orthophoria of raising the bed-head 70~80 degrees for the insertion of gastric canal in children undergoing mechanical ventilation,its once successful rate of intubation improves significantly.
