无创正压通气治疗顽固性心力衰竭的疗效分析

The efficacy of noninvasive airway pressure ventilation in the treatment of refractory heart failure

目的观察无创正压通气（NAPV）治疗顽固性心力衰竭（RHF）的临床疗效。方法选取我院2006年5月～2012年5月顽固性心力衰竭患者80例，使用NAPV治疗2h后，观察治疗前后的呼吸频率（RR）、心率（HR）和动脉血pH、动脉血氧分压（PaO2），SaO2等血气指标的变化。结果本组80例患者行无创正压通气治疗后，显效38例，有效33例，无效9例。有效率88．75％，治疗2h后患者RR、HR、pH、PaO2、SaO2较治疗前均有显著改善，差异有统计学意义（P〈0．05）。结论无创正压通气是顽固性心力衰竭有效的治疗方法之一。

Objective To observe the efficacy of clinical studies of noninvasive pasitive pressure ventilation in the treat- ment of refractory heart failure. Methods A total of 80 patients with refractory heart failure were selected and given NAPV therapy. Arterial blood gas,respiratory rate,heart rate,and arterial pH, arterial partial pressure of oxygen （Pa02）, Sa02 were measured and recorded before and two hours after NAPV therapy. Results A total of 80 patients treated after NAPV , there were 38 cases markedly effective, 33 cases effective, 9 cases failed. The effective rate was 88.75%. After two hours,the RR, HR, pH, PaO2, Sa02 of all patients treated for NAPV were significantly improved than before （P 〈 0.05）. Conclusion NAPV is one of the effective treatment to RHF.
