重症监护室先天性心脏病患儿术后呼吸机撤机失败的影响因素分析

Analysis on the Influencing Factors of Postoperative Ventilator Weaning Failure in Children with Congenital Heart Disease in Intensive Care Unit

目的分析重症监护室(ICU)先天性心脏病患儿术后呼吸机撤机失败的影响因素。方法回顾性分析2022年1月至2023年1月期间128例ICU先天性心脏病手术患儿的临床资料,记录术后呼吸机撤机失败发生情况,采用单因素分析和多因素Logistic回归分析探讨呼吸机撤机失败的影响因素。结果128例患儿术后呼吸机撤机失败发生率为18.75%。单因素和多因素Logistic回归分析显示,术前改良Ross评分高、合并气道畸形、撤机前机械通气时间>7 d、CPB时间长是术后呼吸机撤机失败的影响因素(OR>1,P<0.05)。结论ICU先天性心脏病患儿术后存在呼吸机撤机失败发生风险,撤机失败与患儿术前改良Ross评分高、合并气道畸形、撤机前机械通气时间>7 d、CPB时间长有关。

Objective To analyze the influencing factors of postoperative ventilator weaning failure in children with congenital heart disease in intensive care unit(ICU).Methods The clinical data of 128 ICU children with congenital heart disease surgery from January 2022 to January 2023 were retrospectively analyzed.The occurrence of postoperative ventilator weaning failure was recorded.Univariate analysis and multivariate Logistic regression analysis were used to explore the influencing factors of ventilator weaning failure.Results The incidence of ventilator weaning failure in 128 children was 18.75%.Univariate analysis and multivariate Logistic regression analysis showed that high preoperative modified Ross score,airway malformation,mechanical ventilation time>7 days before weaning,and long CPB time were the influencing factors of postoperative ventilator weaning failure(OR>1,P<0.05).Conclusions ICU children with congenital heart disease have the risk of ventilator weaning failure after surgery.The failure of ventilator weaning is related to the children's high preoperative modified Ross score,airway malformation,mechanical ventilation time>7 days before weaning and long CPB time.
