BIPAP无创正压通气治疗急性高原肺水肿低氧血症疗效观察

目的探讨鼻面罩B IPAP正压通气治疗急性高原肺水肿低氧血症的疗效。方法30例急性高原肺水肿低氧血症患者随机分为鼻面罩B IPAP正压通气治疗组(试验组)和常规鼻导管吸氧治疗组(对照组)各15例,正压通气组选择S/T模式,给予吸气压(IPAP)数值预先置于较小参数,6cmH2O开始,逐渐提高到12~20cmH2O,间歇应用低呼气压(EPAP)2~5cmH2O,氧流量4~6L/m in,每日上下午各持续通气4小时治疗。结果B IPAP正压通气治疗组经3天治疗后与鼻导管吸氧治疗组比较,PaO2、PaCO2、SaO2的改善更为明显,气急、胸闷等不适明显缓解,心率、呼吸频率降至正常范围,两组间比较存在明显差异。结论鼻面罩B IPAP正压通气对急性高原肺水肿所致的低氧血症治疗效果明显,可作为一线治疗予以推广。

THE EFFECTIVENESS STUDY OF USING BIPAP TREATMENT ON ACUTE MOUNTIAN PULMONARY EDAME ACCOMPANIED WITH HYPOCHROMIA IN LIN 2HI PREFECTURE

Purpose To study the effectiveness of BIPAP treatment on acute mountain puimonary edema accompanied with hypochromia. Methods 30 patients with acute mountain pomonary edema accompanied with hypochromia,were randomiy divided into study group with BIPAP treatment,ahd control group with routine oxygen treatment.In study group,S/T model was conducted by starting fron 6cmH2O to 12-20cm H2O gradually,and kept oxygen flow rate on 4-6ml/min with 4 hours twice per each day.Results After 3days late,Pao2 PaCO2 SaO2 in study group were obviously improved comparing with control group,there wsa significant defferences existed in two groups.Conclusion BIPAP is effect to treat acute mountain pulmonary edema accompaneied with hypochromia,and could be considered as clinic treatment to promote.
