抢救室中无创通气治疗急性左心衰竭疗效观察

Observation on the Curative Effect of Non-invasive Ventilation in Rescuing Patients With Acute Left Heart Failure

目的探讨早期无创正压通气治疗急性左心衰竭在急诊抢救室中临床疗效观察。方法选择我院2016年1月—2018年1月急诊抢救室中诊断为急性左心衰竭患者60例作为研究对象。将其随机分为对照组(30例)和实验组(30例)。对照组给予常规抢救措施;实验组在常规抢救措施早期给予无创正压通气。观察治疗前及后15分钟、30分钟、60分钟、90分钟、120分钟的血压、心率、呼吸频率、血气分析,主诉症状缓解时间及抢救室滞留时间等指标。结果两组治疗后的血压、心率、呼吸频率及血气分析等临床指标均较治疗前有明显改善,差异具有统计学意义(P <0.05);采用无创正压通气的实验组总有效率为96.7%,采用常规抢救措施的对照组总有效率为70.0%,实验组高于对照组,差异具有统计学意义(P <0.05)。结论入抢救室即应用无创正压通气治疗急性左心衰竭时能迅速改善患者症状和低氧血症,减少患者在急诊抢救室滞留时间。

Objective To investigate the clinical effect of early non-invasive positive pressure ventilation on acute left ventricular failure in emergency room. Methods 60 cases of patients with acute left heart failure diagnosed in emergency room of our hospital from January 2016 to January 2018 were selected as the study subjects. They were randomly divided into control group(30 cases) and experimental group(30 cases). The control group was given routine rescue measures. The experimental group was given noninvasive positive pressure ventilation at the early stage of routine rescue measures. The blood pressure, heart rate, respiratory rate, blood gas analysis, remission time of complaint symptoms and retention time of rescue room were observed before and after treatment for 15 minutes, 30 minutes, 60 minutes, 90 minutes and 120 minutes. Results After treatment, the blood pressure, heart rate, respiratory rate and blood gas analysis of the two groups were significantly improved compared with those before treatment, and the difference was statistically significant(P < 0.05). The total effective rate of the experimental group with noninvasive positive pressure ventilation was 96.7%, and that of the control group with conventional rescue measures was 70.0%. The experimental group was higher than that of the control group, with statistical significance(P < 0.05). Conclusion Non-invasive positive pressure ventilation can improve the symptoms and hypoxemia of patients with acute left heart failure and reduce the duration of stay in the emergency room.
