目的观察两种吸痰方法对呼吸衰竭患者机械通气的效果.方法将106例呼吸衰竭机械通气患者随机分为对照组和观察组,各53例.观察组采用封闭式吸痰,对照组采用开放式吸痰.观察吸痰过程患者SaO2值、HR的变化、肺部感染率、血气分析以及气道黏膜的损伤情况等.结果两组SaO2变化、肺部感染情况和血气分析比较,均P＜0.05,差异有显著性意义;心率下降＞20%例数、气道黏膜损伤发生率对照组明显高于观察组(P＜0.01).结论密闭式吸痰较开放式吸痰能更好维持患者的氧合状态,减少气道黏膜损伤,有效防止交叉感染,操作安全性强.

Objective To evaluate the influence of two sputum suction methods on the mechanical ventilation of respiratory failure patients.Methods A total of 106 respiratory failure patients on mecharical ventilation were randomly divided into two groups:the observational group and the control group,each with 53 cases.Closed suction was used in the observational group,while opened suction was used in the control group.The SpO2,variabilities of heart rate,pulmonary infections,arterial blood gas and the injury of the airway mucosa were mornitored and recorded during the course of suctioning.Results The SpO2 ,pulmonary infections and blood gas were significantly different between the two groups (P ＜0.05) .The cases with the HR decreasing amplitude greater than 20%,and the rate of the airway mucosa injury were significantly higher in the control group than those in the observational groups (P ＜ 0.01) .Conclusions Compared with opened suction,closed suction can maintain better oxygenation state.It also leads to reduction of the airway mucosa injury.In addition,it prevents crossed infections effectively,with a safe manipulability.
