无创双相正压通气治疗中重度Ⅱ型呼衰的探讨

Noninvasive bi-level positive pressure ventilation in patients with moderate or severe degree Ⅱ type respiratory failure

目的 探讨无创通气对中重度Ⅱ型呼吸衰竭的临床效果。方法 5 1例中重度Ⅱ型呼衰患者随机分为通气治疗组和药物治疗组 ,33例采用面罩无创通气。结果 通气组PaO2 升高明显快于药物组 (P <0 0 5 ) ,PaCO2 在 4h内下降不明显 (P >0 0 5 )。结论 无创通气对中重度Ⅱ型呼吸衰竭疗效较好 ,易耐受 ,可减少气管插管 ,易于基层推广。

Objective Investigation of the effect of noninvasive bi level positive pressure ventilation in patients with moderate or severe degree Ⅱ type respiratory failure.Methods 51 patients with moderate or severe degree Ⅱ type respiratiory failure were randomized into ventination treatment group and drug treatment group.33 patients were treated with noninvasive ventilation.Results Noninvasive ventilation could increase PaO 2 faster than drug treatment (P<0 05),there was no significant change of PaCO 2 within 4 hours between the two groups (P>0 05) Conclusion Noninvasive ventilation was effective for patients with moderate or severe degree Ⅱ type respiratory failure. It may reduce endotracheal intubation and be used in clinical practice.
