目的探讨无创双水平正压通气治疗急性左心衰竭的方法及临床效果。方法回顾性分析2009年6月至2012年3月无创双水平正压通气治疗的46例急性左心衰竭患者临床资料。结果 46例患者均在常规综合治疗基础上给予无创双水平正压通气,治疗前与治疗2h后比较,患者RR、HR、SBP、SaO2、pH值、PaO2、PaCO2差异均有统计学意义(P<0.05);46例患者中显效36例,有效8例,总有效率约95.7%。结论无创双水平正压通气治疗急性左心功能衰竭迅速、简便、安全,疗效肯定,并发症少,能缩短病程,提高抢救成功率。
Objective To investigate the methods and clinical effects of noninvasive bi-level positive pressure ventilation in the treatment of acute left heart failure. Methods The clinical data of 46 patients with acute left heart failure who underwent noninvasive bi-level positive pressure ventilation between June 2009 and March 2012 were retrospectively analyzed. Results All the 46 patients were given noninvasive bi-level positive pressure ventilation on the basis of conventional comprehensive therapy. Before treatment and after 2 hours of treatment, the differences in RR, HR, SBP, SaO2, pH, PaO2 and PaCO2 were statistically significant (P <0.05). Among the 46 patients, 36 cases were markedly effective and 8 were effective. The total effective rate was 95.7%. Conclusion Noninvasive bi-level positive pressure ventilation has the advantages of rapid, simple and safe treatment of acute left heart failure with definite curative effect and less complications, which can shorten the course of disease and improve the success rate of rescue.
