1、不同通气策略在ARDS治疗中的临床疗效观察[摘要]目的探讨不同通气策略对急性呼吸窘迫综合征(ARDS)患者低氧血症及血流动力学的影响。方法选择本院2012年7月〜2015年2月收治的71例ARDS患者,符合纳入标准的63例,分为3组,每组21例,分别为常规机械通气组(SP)、肺开放组(RM)和俯卧位机械通气组(PP)o记录各组实施后24h和48h的血氧分压(Pa02)、血氧饱和度(Sp02)、二氧化碳分压(P&C02)、氧合指数(Pa02/Fi02)及肺开放和俯卧位通气前后心率(IIR)、中心静脉压(CVP)、平均动脉压(MAP)。结果肺
2、开放组和俯卧位组通气后24h和48h的Pa02、Sp02、Pa02/Fi02与常规机械通气组通气后24h和48h比较有明显的增加(P0.05)o肺开放后CVP短暂升高、MAP下降,结束肺开放后逐渐恢复至基础值。肺开放前后HR无明显变化,俯卧位通气前后CVP、MAP、HR均无明显变化(P>0・05)。结论肺开放和俯卧位通气在急性呼吸窘迫综合征治疗中的临床治疗效果优于常规机械通气,肺开放对血流动力学有短暂影响,俯卧位通气对血流动力学无明显影响。[关键词]急性呼吸窘迫综合征;肺开放(肺复张);俯卧位通气;常规机械通气;血流动力学[中图分类号]R
