摘要 目的了解密闭式吸痰对急性呼吸窘迫综合征患者肺换气功能的影响,总结行密闭式吸痰对ARDS患者的护理方法。方法随机抽取45名需要吸痰的ARDS患者,分别对其采用开放式气管内吸痰及密闭式气管内吸痰,观察吸痰前后患者的动脉血氧分压(PaO2)、动脉血氧饱和度(SaO2)、脉搏血氧饱和度(SpO2)、肺泡-动脉血氧分压差[P(A-a)O2]的变化情况,并分别记录两项操作所耗费的时间。结果开放式吸痰后患者PaO2、SaO2、SpO2与吸痰前比较均显著降低,P(A-a)O2较吸痰前增高(P<0.05);密闭式吸痰前后比较上述指标差异无统计学意义(P>0.05)。开放式吸痰平均耗费时间(162±15)s;密闭式吸痰平均耗费时间(93±12)s,两者对比差异有统计学意义。结论密闭式吸痰对ARDS患者肺换气功能影响较小,临床应用比较安全,并且可以提高临床护理工作效率。
