摘要 目的:在急性呼吸窘迫综合征(ARDS)治疗过程中,探索肺复张的时机。方法:选取3例并发ARDS的甲型H1N1流感患者,设置呼吸机基本参数:通气模式压力调节-容量控制(PRVC),潮气量(Vt)6~8mL/kg,较高呼气末正压(PEEP),根据氧合目标是否达到,平台压是否急速增加和>40cmH2O,是否出现CO2潴留,决定是否使用肺复张。结果:患者均存活,均未出现气胸,行肺复张1例,颈部出现皮下气肿,在肺复张过程中需要用血管活性药物保证血压稳定。结论:ARDS时,如果在增加PEEP后,PaO2有改善,平台压<30cmH2O(肥胖者<40cmH2O),应保持在这个水平直至持续30h。肺复张动作的适应症是:ARDS时,PEEP已经达到较高水平仍然存在的顽固性低氧血症。肺复张动作的时机是:如果PEEP已经达到较高水平,氧合仍不稳定,平台压越来越高,降低潮气量不能阻止平台压增加,特别是PaCO2突然增加,血流动力学尚稳定。去复张后,调整PEEP可以达到氧合目标的患者,不再作肺复张操作。
