患儿男性,4个月。3.97kg,患ASD、VSD、PDA。术前Hct34％。不用血。作者规定婴幼儿体外外循环(CPB)预充标准:Terumo储血袋(400ml),Capiox308膜肺,Terumo CXCR40心脏切开储血器,动、静脉管道内径1/4。本例为减少预充量用Terumo储血袋(100ml),不用动脉滤器及其旁路,尽可能缩短管道长度,从而使CPB预充量减少至390ml,包括乳酸林格、NaHCO_3(20mEq)和肝素(1500u)。
Children with children, 4 months. 3.97kg, suffering from ASD, VSD, PDA. Preoperative Hct34%. No blood. The authors prescribe the CPB prefilled standard: Terumo blood reservoir (400 ml), Capiox 308 membrane lung, Terumo CXCR40 cardiothoracic device, arterial and venous internal diameter 1/4. In this example, the Terumo blood bag (100 ml) was prefilled to minimize the length of the tubing without an arterial filter and its bypass, thereby reducing the CPB prefill volume to 390 ml including lactated Ringer, NaHCO 3 (20 mEq) and Heparin (1500u).
