强化胃残余量控制对呼吸机相关性肺炎的预防效果研究

Effect of intensive control of residual amount in stomach on prevention of ventilator associated pneumonia

目的探讨强化胃残余量控制对预防肠内营养患者呼吸机相关性肺炎的作用。方法分析96例机械通气超过48h的患者，随机分成病例组和对照组各48例。分别采用强化胃残余量控制和普通控制。比较2组呼吸机相关肺炎的发生率、病死率、机械通气时间及住院时间。结果病例组呼吸机相关性肺炎发生率为20．83％、病死率18．75％、机械通气时间（15．21±2．36）d、住院时间（22．38±12．34）d；对照组呼吸机相关性肺炎发生率为39．58％、病死率39．58％、机械通气时间（19．85±4．58）d、住院时间（29．46±15．24）d。2组各项指标比较差异显著。结论强化胃残余量控制可减少呼吸机相关性肺炎的发生，缩短机械通气和住院时间。

Objective To investigate the effect of intensive control of residual amount in stomach on prevention of ventilator associated pneumonia （VAP） during the process of enteral nutrition. Methods 96 patients with mechanical ventilation （MV） more than 48 hours were randomly divided into the case group and the control group, they were treated with intensive control and common control of residual amount in stomach respectively. The incidence rate of VAP, mortality rate, time of ventilation and hospitalization time were compared between the two groups. Results The incidence rate of VAP was 20.83% in the case group and mortality rate was 18.75%,the time of MV was （15.21±2.36） days,the hospitalization time was （22.38±12.34） days. The incidence rate of VAP was 39.58%, mortality rate was 39.58%,the time of MV was （19.85±4.58）days,the hospitalization time was （29.46±15.24）days in the control group. Conclusions Intensive control of residual amount in stomach could be helpful to decrease the incidence of VAP and mortality rate of patients with mechanical ventilation using nasal feeding,also shorten the time of MV and the hospitalization time.
