听诊结合吸痰管刺激吸痰法对机械通气患者动脉血气的影响

目的:探讨听诊结合吸痰管刺激吸痰法对机械通气患者动脉血气的影响。方法:将62例患者随机分为观察组与对照组各31例。对照组患者有明显痰鸣音时或呼吸机气道峰压升高报警立即给予吸痰,观察组患者采用听诊结合吸痰管刺激吸痰法。比较两组患者吸痰前、吸痰结束时、吸痰后5 min动脉血气变化;吸痰前后血压、心率变化;平均吸痰量、机械通气时间、住院天数、住院费用、呼吸机相关性肺炎发生情况。结果:观察组患者吸痰前后PaO2、SaO2均处于高值,影响不明显,PaCO2较对照组患者下降明显,对照组患者吸痰前后PaO2、SaO2波动明显;两组患者吸痰前后血压、心率变化比较差异无统计学意义(P>0.05);平均吸痰量、机械通气时间、住院天数、住院费用、呼吸机相关性肺炎发生情况比较差异有统计学意义(P<0.01)。结论:为机械通气患者实施听诊结合吸痰管刺激吸痰能有效提高血氧含量,预防因气道阻塞时间长致机体缺氧造成的各种并发症,减少呼吸道黏膜损伤。

Effect of stimulated sputum suctioning with suction tube by auscultation detection on ABG of the patients with mechanical ventilation

Objective: To explore the effect of stimulated sputum suctioning with suction tube by auscultation detection on ABG of the patients with mechanical ventilation.Methods: 62 patients were randomly divided into observation group and control group(31 patients for each group).In the control group,the sputum suctioning was immediately conducted when the patients were found to have distinct wheezing sound or the alarm was heard when the peak airway pressure was increased;in the observation group the patients were ...
