呼气未正压通气治疗急性肺水肿

目的:评价呼气末正压通气(PEEP)治疗急性肺水肿的临床疗效。方法:30例急性肺水肿患者,在药物治疗基础上,加用PEEP(3～8cmH_2O)机械通气治疗,对比治疗前后血压(BP)、呼吸(R)、心率(HR)、氧饱和度(SaO_2)等动脉血气指标及胸片变化,同时与30例常规药物治疗组进行对比。结果:经PEEP机械通气治疗0.5～1h后,29例呼吸频率减慢、心率减慢,氧饱和度上升,血气指标好转,心功能改善,仅一例无效死亡。总有效率96.67％。结论:呼气末正压通气是治疗急性肺水肿快速、有效的方法。

Clincal Effect of PEEP in the Treatment of Acute Pulmonary Edema

To evaluate the clinical effect of mechanical ventilation with PEEP in the treatment of acute pulmonary edema. Methods: 30 patients with acute pulmonary edema were treated by conventional drugs and the mechamical ventilation with 3-8 cmH2O PEEP. The results of BP, R, HR, SaO2, blood gas analysis and chest X-ray before and after PEEP were compared treatment. Control group:30 patients were treated with conventional drugs alone, and the results were compared with those of PEEP group. Results: After PEEP treatment 29 patients were recovered with no more dyspnea, tachycardia and hypoxemia. One patient died. The efficacy was 96.67 % . Conclusion: Mechanical ventilation with PEEP is feasible and effective in the treatment of acute pulmonary edema.
