目的探讨对比密闭式湿化与开放式湿化对新生儿呼吸机相关性肺炎(VAP)发生率的影响。方法将120例新生儿重症监护病房行气管插管机械通气治疗患儿,随机分为试验组和对照组各60例,采用密闭式的湿化方法,对照组采用开放式的湿化方法,比较2组患儿VAP发生率。结果试验组机械通气的新生儿VAP发生率为11.67%,低于对照组的21.67%,差异有统计学意义(P<0.05)。结论密闭式气管内湿化效果优于开放式气管内湿化,在降低气管内痰液粘稠度,降低VAP发生率,减少机械通气时间有明显改善效果,而且操作简便,容易掌握,更增加了气管内吸痰的安全性和舒适度。
Objective To investigate the effects of confined humidification and open humidification on the incidence of neonatal ventilator-associated pneumonia (VAP). Methods 120 cases of neonatal intensive care unit tracheal intubation mechanical ventilation treatment of children, were randomly divided into experimental group and control group of 60 cases, the use of closed wet method, the control group open wet method, compared 2 groups of children with VAP incidence. Results The incidence of VAP in the experimental group was 11.67%, lower than that of the control group (21.67%), the difference was statistically significant (P <0.05). Conclusions Closed endotracheal humidification is superior to open endotracheal tube wetting. It can significantly reduce sputum viscosity, reduce the incidence of VAP and reduce the time of mechanical ventilation, and it is easy to operate, easy to grasp and even more Endotracheal suctioning safety and comfort.
