摘要 目的观察不同单肺通气时程对食管癌手术患者支气管肺泡灌洗液中肿瘤坏死因子-α(TNF-α)和白细胞介素-8(IL-8)的影响。方法选择左侧开胸食管癌和肺癌根治术患者36例为单肺通气组,按单肺通气时间分为:O1组(<1.5 h)、O2组(2.0~2.5 h)、O3组(3.0~3.5 h),每组12例;选择非胸科手术患者为对照组,每组12例,通气时间为3.0~3.5 h。观察各组患者在麻醉前(T1)、麻醉后(T2)、手术结束前(T3)、术后24 h(T4)的HR、MAP、SpO2、CVP、Ppeak、PETCO2、血气分析值以及T2~T3时肺泡灌洗液中TNF-α和IL-8的变化。结果 HR、MAP、SpO2、PETCO2、MV、VT以及血气分析值在各组间比较差异无统计学意义(P>0.05)。与T1时比较,PaO2在T2~T4、SaO2在T2和T3时显著升高(P<0.01)。在T3时点,O1~O3组的左右肺TNF-α和IL-8值、对照组的右肺TNF-α和IL-8值均比T2时点升高(P<0.05);O2组左肺TNF-α、O1~O3组左肺IL-8值均比右肺高(P<0.05)。结论不同单肺通气时程对患者术中、术后24 h的血流动力学、血气值无显著影响,但肺泡灌洗液TNF-α、IL-8浓度随着单肺通气时间延长而增加,萎陷肺比通气肺明显,以单肺通气超过3 h最显著。
