无创呼吸机治疗手术后低氧血症疗效评价

目的评价Knightstar-330无创呼吸机治疗手术后低氧血症患者的疗效。方法将60例符合诊断标准的手术后低氧血症患者随机分成两组,即治疗组(n=30)与对照组(n=30),进行分组治疗。治疗组在常规治疗的基础上,加用Knightstar-330无创呼吸机治疗;对照组只给予常规治疗及鼻导管吸氧。结果治疗组30例中有28例在24小时后病情缓解,2例恶化,改用有创通气;对照组30例中有9例在24小时后病情基本缓解,另21例病情加重,使用有创或无创通气。结论Knightstar-330无创呼吸机治疗手术后低氧血症患者有明显疗效,但亦有其局限性,若对无创通气初期血气分析无改善者,要尽快进行有创通气。

Efficacy of Non-invasive pressure support ventilation by knightstar-330 in the treatment of the patients with hypoxemia after chest and abdomen operation

Objective To investigate the efficacy of non-invasive pressure support ventilation by Knightstar-330 in the treatment of the patients with hypoxemia after chest and abdomen operation(HACAO).Methods 21 patients with HACAO were divided into two groups randomly.trial group(n=11) was treated with non-invasive pressure support ventilation by Knightstar-330 in addition to conventional therapy,and control group was treated with conventional therapy and canul oxygen therapy.Results Clinical symptoms of 28 cases in trial group were improved after 24 hours of non-invasive pressure support ventilation by Knightstar-330,the other two was changed to invasive ventilation because of aggravation.In control group there were 9 cases improved,21 cases were changed to non-invasive or invasive ventilation because of aggravation.Conclusions Non-invasive pressure support ventilation by Knightstar-330 is effective in patients with HACAO.
