The value and the influencing factors of modified sputum-sucking method in prevention and treatment of ventilator-associated pneumonia in patients with mechanical ventilation

目的探讨改良吸痰方法在防治机械通气患者呼吸机相关性肺炎的作用及影响因素。方法分析本院行呼吸机机械通气患者512例临床资料,对照组200例采用开放式气管内吸痰,实验组312例采用密闭式气管内吸痰;比较2组患者吸痰前后指脉血氧饱和度、Sp O2恢复到基线水平的时间、气道峰压及呼吸机相关性肺炎发生率,观察2组吸痰方法的不良反应。结果实验组呼吸机相关性肺炎发生率、病死率明显低于对照组(P<0.05);实验组患者Sp O2恢复到基线水平的时间均优于对照组(P<0.05)。结论采用密闭式气管内吸痰法有助于提高吸痰效果,减少呼吸机相关性肺炎的发生,值得推广。

Objective To explore the value and the influencing factors of the modified spu- tum- sucking method on in prevention and treatment of ventilator - associated pneumonia in pa- tients with mechanical ventilation. Methods The clinical data of 512 patients with mechanical ven- tilation were retrospectively analyzed, the control group with 200 cases was applied the open endo- tracheal sputum suction while the study group with 312 cases was carried out closed endotracheal sputum suction, the pulse oxygen saturation, peak airway pressure, and the incidence of ventilator -associated pneumonia were analyzed. Results Compared with the control group, the incidence and mortality of ventilator- associated pneumonia of study group were lower than that in the control group （P 〈 0.05） . The time of SpO2 back to basis level of study group was better than that in the control group（P 〈 0.05）. Conclusion The modified sputum- sucking method can reduce respira- tory tract damage and decrease the incidence of ventilator- associated pneumonia, so it is worthy of spreading.
