无创正压通气抢救急性左心衰竭合并Ⅰ型呼吸衰竭的应用研究

Investigate the application of non-invasive positive pressure ventilation in the saving of acute left heart failure combined with type Ⅰ respiratory failure

目的探讨无创正压通气(NIPPV)抢救急性左心衰竭合并Ⅰ型呼吸衰竭的疗效。方法将60例急性左心衰竭合并Ⅰ型呼吸衰竭的患者随机分为治疗组和对照组,治疗组在常规治疗基础上加用NIPPV治疗,对照组应用常规治疗,对两组治疗效果进行评价。结果治疗组治疗后PaO2、SaO2明显升高,RR、HR明显降低,对平均动脉压影响不大,有效率达86.7%;对照组有效率为66.7%,两组有效率差异有显著性,P<0.05。结论NIPPV抢救急性左心衰竭合并Ⅰ型呼吸衰竭疗效显著,值得推广。

To investigate the application non-invasive positive pressure ventilation（NIPPY） in the saving of acute left heart failure（ALHF） combined with type Ⅰ respiratory failure（RF- Ⅰ）.Method 60 patients with ALHF combined with RF- Ⅰ were divided into two groups. 30 patients were applied NIPPV on the base of conventional treatment as treatment group, the other 30 patients were given conventional treatment without NIPPV as control group, compare and evacuate the clinical effects in the two groups. Result In treatment group, both PaO2 and SaO2 were obvious increased, the respiratory rate and heart rate were slowed. There were no change in the mean blood pressure. Total effective rate was 86.7%. Compared with the total effective rate only 66.7% in control group, significant difference（P〈0. 05） was shown. Conclusion NIPPV shows remarkable effect in the saving of ALHF combined with RF- Ⅰ, such approach is worth spreading.
