【摘要】:目的 探讨允许性高碳酸血症(permissive hypercapnia,PHC)在胸腔镜治疗新生儿先天性食管闭锁手术中的应用效果。方法 选择行胸腔镜下先天性食管闭锁(congenital esophageal atresia,CEA)I期吻合术的新生儿30例,男17例,女13例,出生1~5d,体重1.42~3.28kg,ASAⅡ或Ⅲ级。随机分为PHC组(P组)和对照组(C组),每组15例。两组新生儿均采用气管内插管静-吸复合全麻,FiO2100%,新鲜气流量2L/min。P组VT6ml/kg,C组VT_10ml/kg。根据气道压及血气分析结果,通过调节呼吸机RR和PEEP参数,维持P组PaCO_2为60~80mm Hg,C组PaCO_2为35~45mm Hg。记录气胸建立前(T0)、气胸建立后15min(T_1)、30min(T_2)、60min(T3)和气胸解除后15min(T4)的动脉血气分析。记录术后2h内气胸发生情况及术毕至撤离呼吸机时间。结果T_1时,P组P_(ET)CO_2明显高于C组[(73.93±3.53)mm Hg vs.(41.53±1.59)mm Hg,P0.05],动脉血pH值明显低于C组(7.25±0.02vs.7.38±0.03,P0.05),PaCO_2明显高于C组[(74.80±2.45)mm Hg vs.(41.93±1.39)mm Hg,P0.05];T2时,P组P_(ET)CO_2明显高于C组[(73.46±3.04)mm Hg vs.(41.30±1.29)mm Hg,P0.05],动脉血pH值明显低于C组(7.24±0.01vs.7.37±0.03,P0.05),PaCO_2明显高于C组[(75.33±2.19)mm Hg vs.(42.01±1.31)mm Hg,P0.05];T3时,P组P_(ET)CO_2明显高于C组[(74.13±2.85)mm Hg vs.(41.67±1.35)mm Hg,P0.05],动脉血pH值明显低于C组(7.25±0.01vs.7.38±0.02,P0.05),PaCO_2明显高于C组[(75.20±2.08)mm Hg vs.(42.13±1.19)mm Hg,P0.05]。P组气胸发生率明显低于C组(6.7%vs.40.0%,P0.05)。P组与C组术毕至撤离呼吸机时间差异无统计学意义[(3.6±0.6)d vs.(3.5±0.6)d]。结论 允许性高碳酸血症(PaCO_260~80mm Hg)可以安全应用于胸腔镜治疗新生儿先天性食管闭锁手术,同时可以明显降低气胸的发生率。
