摘要 目的:应用控制性降压技术探讨小儿双侧腭裂整复术中不同的急性高容量血液稀释(HHD)程度对腭裂患儿术中炎性细胞因子的影响。方法:选择红细胞压积(Hct)>35%,年龄6~8个月行双侧腭裂整复术的患儿90例,按随机数字法分为A组(Hct>35%)、B组(Hct:25%~30%),C组(Hct:20%~25%),每组30例。B组与C组患儿在常规麻醉诱导后通过输入晶胶液体控制Hct浓度,必要时通过输注多巴胺维持血压。分别在术前(T1)、术中30min(T2)、术毕(T3)及术后3h(T4)抽取动脉血样本,应用免疫组化技术检测各时间点的细胞因子IL-1β和TNF-α在血浆中的表达,记录术中失血量和输血量。结果:各组与术前相比IL-1β和TNF-α蛋白表达增加,但差异无统计学意义。与A组比较,B、C组在T2时点的IL-1β和TNF-α蛋白表达量显著减少(P<0.05)。3组间相对失血量无统计学差异,但B、C组输血例数明显低于A组(P<0.05)。结论:HHD可以明显减少小儿双侧腭裂整复术术中的输血量,对小儿术中的炎性细胞因子无不良影响。
