急性呼吸窘迫综合征患者采用不同深度密闭式吸痰的效果研究

The effect of different depth airtight suction in patients with acute respiratory distress syndrome

目的观察急性呼吸窘迫综合征患者采取不同深度密闭式吸痰的效果,探讨急性呼吸窘迫综合征患者行机械通气期间最佳的吸痰深度。方法将36例行机械通气的急性呼吸窘迫综合征患者随机分成观察组和对照组各18例,观察组采用密闭式浅部吸痰(吸痰管超过气管导管前端1 cm),对照组采用密闭式深部吸痰(临床常规方法,即吸痰管深入气道,遇阻力后退出0.5～1 cm),比较2组患者吸痰前后血氧饱和度、心率、平均动脉压、吸痰前后肺部痰鸣音、日吸痰次数及吸痰并发症的发生率。结果 2组患者吸痰后比较,观察组吸痰后引起心率、平均动脉压变化幅度较对照组比较小,观察组气道黏膜损伤、心律失常、出现痰痂不良事件发生率低,2组间比较均有统计学意义(P<0.05),而对于日吸痰次数、吸痰间隔时间,2组比较差异无统计学意义(P>0.05)。结论急性呼吸窘迫综合征患者机械通气期间行密闭式浅部吸痰能有效吸痰的同时,减少对气道的刺激及不良反应,是一种安全有效的吸痰方式。

Objective To analysis the effect of different depth airtight suction in patients with acute respiratory distress syndrome.Methods 36 patients with acute respiratory distress syndrome were randomly divided into control group and intervention group,each group had 18 patients.Patients in control group were given traditional deep layer of airtight suction.While patients in intervention group were given ministry suctioning.The oxygen saturation,heart rate,mean arterial pressure,the suctioning number and the incidence of complications were compared between the 2 groups.Results The heart rate,mean arterial pressure and the incidence of complications in intervention group was lower than that of control group（P0.05）.Conclusion Ministry suctioning is effective and safe.
