目的探讨无创正压通气治疗急性左心衰竭的效果。方法选取100例急性左心衰竭患者,随机分为对照组和研究组各50例,对照组进行面罩吸氧救治,研究组在对照组基础上进行无创正压通气治疗方法,对比分析两组治疗急性左心衰的临床疗效。结果对照组显效28例,有效10例,无效12例,总有效率76.0%;研究组显效39例,有效9例,无效2例,总有效率96.0%。对照组中有7例患者救治无效死亡,病死率为14.0%。研究组中有1例患者救治无效死亡,病死率为2.0%。研究组治疗后的心率、呼吸频率及血氧分压、血氧饱和度显著优于对照组,差异具有统计学意义,(P<0.05)。结论无创正压通气治疗应用在急性左心衰竭患者的治疗中具有明显的积极作用,不仅能够更好的保障患者的身心健康,而且其临床应用价值也是非常值得肯定的。
Objective To investigate the effect of noninvasive positive pressure ventilation in the treatment of acute left heart failure. Methods 100 cases of acute left heart failure patients were randomly divided into control group and study group of 50 cases, the control group were mask oxygen treatment, the study group in the control group based on noninvasive positive pressure ventilation treatment, comparative analysis of two groups of treatment Acute left heart failure clinical curative effect. Results In the control group, 28 cases were markedly effective, 10 cases were effective, 12 cases were ineffective, and the total effective rate was 76.0%. In the study group, 39 cases were markedly effective, 9 cases were effective, 2 cases were ineffective, and the total effective rate was 96.0%. Seven patients in the control group died of treatment failure, the mortality rate was 14.0%. One patient in the study group died of ineffective treatment with a case fatality rate of 2.0%. The heart rate, respiratory rate, oxygen partial pressure and oxygen saturation of the study group were significantly better than those of the control group after treatment, the difference was statistically significant (P <0.05). Conclusion The application of noninvasive positive pressure ventilation in the treatment of patients with acute left heart failure has a significant positive effect, which not only can better protect the patients’ physical and mental health, but also its clinical application value is very worthy of recognition.
