目的:观察双水平气道正压通气(BiPAP)呼吸机在急性左心衰院前急救中的疗效。方法:回顾性分析98例急性左心衰患者的临床资料,其中50例(A组)在院前急救时采用BiPAP呼吸机治疗,自行来院就诊患者为对照组(B组)48例。结果:A组治疗1h后的有效率和24 h死亡率分别为96%和2%,均优于B组的79%和4%P<0.05。结论:院前急救时采用BiPAP呼吸机治疗可较早改善急性左心衰患者的心功能,降低病死率。
Objective: To observe the effect of bi-level positive airway pressure (BiPAP) ventilator in the emergency treatment of acute left heart failure. Methods: The clinical data of 98 patients with acute left heart failure were retrospectively analyzed. Among them, 50 patients (group A) were treated with BiPAP ventilator in first aid before hospitalization, and 48 patients were in control group (group B). Results: The effective rate and the 24-hour mortality rate after 1-hour treatment in group A were 96% and 2%, respectively, which were better than those in group B (79% and 4%, P <0.05). CONCLUSION: BiPAP ventilator treatment in pre-hospital emergency treatment can improve cardiac function and reduce mortality in patients with acute left heart failure earlier.
