摘要:
目的 评估肺超声下驱动压(ΔP)引导的个体化呼气末正压通气(PEEP)联合定期肺复张对Trendelenburg体位下行腹腔镜结直肠癌根治术的老年患者术后肺不张的影响。方法 纳入年龄65~85岁、美国麻醉医师协会分级Ⅰ—Ⅲ级,拟行腹腔镜下结直肠癌根治术的患者62例并分为试验组和对照组(各31例)。2组均在气腹开始后进行第1次肺复张,随后立即以最低ΔP滴定个体化PEEP,气腹结束后进行第2次肺复张。试验组自气腹开始每30 min额外进行一次肺复张,对照组则不干预。以麻醉诱导前(T0)、气腹后30 min(T1)、气腹后90 min(T2)、手术结束时(T3)、进入麻醉复苏室(PACU)45 min后(T4)为观察记录时间点。记录T0、T3和T4时肺超声评分(LUS);T1—T3时肺动态顺应性(Cdyn);T0—T4时间点氧合指数(OI)、平均动脉压(MAP)、心率(HR);记录肺复张期间低血压、PACU中低氧饱和事件以及术后7 d内肺部并发症(POPC)发生率。结果 与对照组相比,试验组在T3和T4时LUS下降(P<0.05),T2、T3时OI和Cdyn升高(P<0.05)。试验组在PACU中低氧饱和事件发生率较对照组下降(P<0.05)。2组患者肺复张期间低血压发生率和术后7 d内POPC发生率差异无统计学意义(P>0.05)。结论 个体化PEEP联合定期肺复张可有效减少老年患者腹腔镜结直肠癌根治术后即刻和PACU中的肺不张。
