摘要
目的:探讨急性呼吸窘迫综合征(ARDS)患者机械通气时应用肺复张策略的疗效与风险。方法:随机将ARDS患者分成两组:A组为对照组,B组为治疗组;两组均用PB840呼吸机采用Bilevel通气模式进行机械通气,原发病治疗相同;B组在A组的通气治疗基础上增加肺复张策略。记录开始前及24、48、72h的氧合指数(PaO2/FiO2)、二氧化碳分压(PaCO2)、是否出现气压伤并进行比对分析。结果:治疗组与对照组比较氧合指数12、24、72h均有明显改善,PaCO2在12、24、72h均有明显降低,而气压伤等并发症并无明显增加。结论:在ARDS机械通气患者中结合应用肺复张策略和Bilevel通气模式是安全有效的。
Objective： To discuss the effect and risk of the lung recruitment maneuvers in the acute respiratory distress syndrome （ARDS） patients. Methods：38 ARDS patients treated with the PB840 ventilator and with the same mode of Belevel were randomized into A and B groups.A group was the control group and the lung recruitment maneuvers have applied in the B groups.The oxygenation index and PaCO2 before and 24,48,72h after enrolling were measured and analyzed. And pulmonary barotrauma incidence were observed. Results： Compared with the control group,the oxygenation index had a significantly improvement and PaCO2 had a significantly decrease 24,48,72h after enrolling in the treatment group.However the pulmonary barotrauma and others complications did not increase.Conclusion： Combine the lung recruitment maneuvers with the mode of Belevel may be safe and effective at the ARDS patients receiving mechanical ventilation.
