吸痰方法对PRVC治疗慢性呼吸衰竭的疗效影响

Effect of sputum aspiration on the treatment for chronic respiratory failure with PRVC

目的观察不同吸痰方法对压力调节容量控制模式(PRVC)治疗慢性呼吸衰竭的疗效。方法选取2008年3月～2010年3月进行PRVC治疗的36例COPD慢性呼吸衰竭患者,随机分为实验组和对照组,每组18例。实试验组采用改良吸痰方法,对照组采用常规吸痰方法,观察治疗2 h、4 h后动脉血气分析(pH、PaO_2、PaCO_2)的变化。结果治疗2 h、4 h后,实验组的pH、PaO_2升高,PaCO_2明显降低,与对照组相比差异有显著意义,P<0.05,P<0.01。结论改良吸痰方法有利于增加PRVC治疗的疗效,值得在临床工作中进一步研究。

Objective To observe the effect of different sputum aspiration on the treatment for chronic respiratory failure（CFF） with PRVC.Method Thirty-six COPD patients with CFF treated by PRVC were selected from March 2008 to March 2010.They were randomly divided into experimental group and controls group,each group has eighteen cases.The experimental group adopted improved sputum aspiration,the controls group with regular sputum aspiration. The pH,PaO_2、PaCO_2 level from analysis of blood gas（ABG） were determined after 2 and 4 hours of treatment. Result The pH,PaO_2 PaCO_2 level from experimental group after 2 hours and 4 hours of treatment was obviously improved,there was siginificant difference.Conclusion The improved sputum aspiration is benifecial to increase the effection for treatment with PRVC and worth to being further studied.
