改良呼吸机管路在机械通气患者氧疗中的效果

目的观察改良呼吸机管路在机械通气患者拔管前氧疗中的应用效果。方法选择2010年3—12月收治的63例机械通气患者作为研究对象，按随机数字表法分为实验组32例和对照组31例。实验组应用改良呼吸机管路给氧法，对照组采用间断气道内滴注湿化法，观察两组患者血氧饱和度、痰痂形成、呼吸道刺激征、气道出血、肺部感染、日吸痰次数及日吸痰量。结果改良呼吸机管路给氧患者在血氧饱和度、痰液黏稠、痰培养阳性等各方面明显优于间断气道滴注湿化法，差异有统计学意义（t分别为5．45，6．91，5．67；P〈0．05）。结论改良后呼吸机管路给氧气道湿化效果好，能够提高患者舒适度及氧疗效果，可以降低患者肺部感染率及相应的气道并发症。

Effect of modified breathing machine pipeline applied in mechanical ventilation patients with oxygen therapy

Objective To observe the effect of modified breathing machine pipeline applied in mechanical ventilation patients with oxygen therapy. Methods Clinical data of 63 patients with mechanical ventilation in the intensive care unit were studied and the patients were admitted from March 2010 to December 2010. 32 patients in experiment group treated by method of modified breathing machine pipeline. 31 patients in the control group used dripping technique via airway for mechanical ventilation. The incidence of oxygen saturation rate, sputum callus formation, airway bleeding, pulmonary infection, the number of daily suctioning, nursing workload were recorded and compared between the two groups. Results The oxygen saturation rate in the observation group increased compared with that of the control group, sputum callus formation, irritating cough, airway bleeding and pulmonary infection were significantly different between 2 groups (t =5. 45,6. 91, 5. 67;P ＜ 0. 01). Conclusions The effect of modified breathing machine pipeline is more reliable, could improve the efficiency and alleviate the nursing workload.
