研究背景:为了减小心肺分流术后凝血紊乱和炎症反应的危害,许多医疗机构在进行新生儿和婴幼儿心脏手术时,将输入新鲜全血作为标准治疗措施。为了启动心肺分流术中侧支循环,可输入新鲜全血,也可输入浓缩红细胞与新鲜冷冻血浆混合血(再造血),本文对这两种方法进行对比研究。方法:单中心双盲性随机对照试验,将接受过心脏外科手术且小于1岁的患儿作为研究对象。侧支循环启动后,根据输入血液成分不同,将患儿 Background: In order to reduce the risk of clotting and inflammatory reactions after cardiopulmonary bypass, many medical institutions import fresh whole blood as a standard treatment during neonatal and infantile cardiac surgery. In order to initiate collateral circulation in cardiopulmonary bypass, fresh whole blood may be introduced, or mixed blood of reconstituted red blood cells and fresh frozen plasma (regenerated blood) may be used. In this paper, we compared the two methods. METHODS: A single-center, double-blind, randomized controlled trial of children undergoing cardiac surgery and less than 1 year of age was included. Collateral circulation started, according to the different components of the input blood, the children will be
