摘要 目的探讨静脉输注小剂量氯胺酮对单肺通气(OLV)致肺损伤的影响。方法将60例行开胸手术的患者随机均分为两组,K组在机械通气前给静脉推注氯胺酮0.4mg/kg,继以5μg·kg^(-1)·min^(-1)持续泵注至手术结束,N组给予相同体积生理盐水作对照。分别在麻醉前(T1)、OLV开始前(T2)、OLV结束后30min(T3)、术后24h(T4)行动脉血气分析,比较两组患者的PaO_2、动脉血二氧化碳分压及氧合指数,并在T2、T3时检测肺泡灌洗液中TNF-α、IL-8水平。结果与T1时相比,两组T2时PaO_2及氧合指数升高(P<0.05),而N组T3、T4时氧合指数降低(P<0.05);与N组相比,T3时K组PaO_2和氧合指数升高(P<0.05),肺泡灌洗液中TNF-α、IL-8的含量降低(P<0.05)。结论小剂量氯胺酮可明显减轻因OLV导致的肺损伤,其机制可能与减少肺内炎性因子的释放有关。
