联合应用SIMV、PSV及PEEP模式抢救重度急性左心衰竭

The Application of Combination of SIMV,PSV and PEEP in Treatment of Severe Acute Left Ventricular Failure

目的:评价联合应用同步间歇指令性通气(SIMV),压力支持通光(PSV),呼气末正压(PEEP)在抢救重度急性左心衰的可行性。方法:30例急性左心衰患者在常规抢救的基础上联合应用SIMV+PSV+PEEP模式通气,对通气1 h、2 h及24 h后的病情与通气前相对比,统计分析心率、氧合指数、血气变化、胸片改变、双肺湿啰音、神志等指标。结果:经呼吸机治疗后,患者病情明显好转,全部病例抢救成功。血气改变有显著性差异(P<0.01)。结论:急性左心衰患者在常规治疗基础上,若病情仍进行性恶化,则需及时行呼吸机治疗,尤其是行呼气末正压治疗。

Objective： To evaluate the clinical effect of combination of SIMV,PSV and PEEP on severe acute left ventricular failure. Methods：Thirty patients were treated by combination of SIMV, PSV and PEEP in addition of routine drugs. HR, PaO2, PaCO2, PaO2/FiO2, chest X-ray, tale, consciousness were examined before the treatment and at 1 hour.2 hours and 24 hours after the treat- ment. Results： After the treatment, the patients＂ conditions were better, all of the patients were recovered. The changes of blood gas showed a statistical significance（P〈0. 01）. Conclusion： After the routine drug treatment in the acute left ventricular failure,if condition of the patients worse, they must be treated with MV,special for PEEP.
