[目的]探讨BIPAP呼吸机在AECOPD合并呼吸衰竭的疗效。[方法]82例COPD合并Ⅱ型呼吸衰竭患者在常规治疗基础上采用BIPAP呼吸机辅助通气作为治疗组,并取同期达同样标准的90例患者仅采用常规治疗作为对照组。[结果]两组治疗后动脉血氧分压(PaO2)都明显上升(P﹤0.01),但治疗组上升更高;治疗组血二氧化碳分压(PaCO2)比治疗前明显下降,治疗前后差异有统计学意义(P﹤0.01),对照组PaCO2治疗前后差异无统计学意义(P﹥0.05);治疗组临床症状缓解例数也明显多于对照组。治疗组治疗失败行气管插管6例,对照组治疗失败行气管插管21例。治疗组平均住院日明显少于对照组。[结论]BiPAP呼吸机辅助通气,对COPD合并轻,中度呼吸衰竭疗效肯定,可降低PaCO2,提高PaO2,减轻症状,有利于呼吸肌疲劳恢复,并减少气管插管率。
[Objective] To investigate the curative effect of BIPAP ventilator in AECOPD with respiratory failure. [Method] 82 COPD patients with type Ⅱ respiratory failure were treated with BIPAP ventilator-assisted ventilation on the basis of routine treatment. 90 patients who took the same standard during the same period were treated with conventional therapy only as the control group. [Results] PaO2 significantly increased after treatment (P <0.01), but the treatment group increased more. PaCO2 in treatment group decreased significantly compared with that before treatment, and there was significant difference between before and after treatment (P <0.01). There was no significant difference in PaCO2 before and after treatment in the control group (P> 0.05). The number of clinical symptom relief in the treatment group was also significantly more than that in the control group. Treatment group failed to endotracheal intubation in 6 cases, control group failed to endotracheal intubation in 21 cases. The average length of stay in treatment group was significantly less than that in control group. [Conclusions] BiPAP ventilator-assisted ventilation has positive curative effect on COPD combined with light and moderate respiratory failure, which can reduce PaCO2, increase PaO2 and relieve symptoms, is conducive to respiratory muscle fatigue recovery and reduce tracheal intubation rate.
