40例新生儿体外循环后手术并发症的分析

Analysis of Complications after Cardiopulmonary Bypass of 40 Neonates

目的 回顾性总结40例新生儿体外循环手术并发症以及与转流时间长短的关系。方法 全部病例分为长 时间转流组(L组,>120min)和对照转流组(C组,<120min),对比分析两组在术后并发症发生的差异,总结新生 儿体外循环的管理经验。结果 L组死亡4例,低心排8例,肾衰2例,弥漫性血管内凝血2例,血培养(+)3例。 C组死亡5例,低心排11例。结论 注重预防、早期阻断全身性炎症反应和良好的体外循环管理是预防新生儿转 流后并发症发生的关键。

Objective To reporte the experience of cardiopulmonary bypass of 40 neonates, and the relationship between the incidences of complications and the cardiopulmonary bypass costed time.Methods Forty patients were divided into two groups in this study. In Group L,10 patients received a long duration of cardiopulmonary bypass(>120 minutes).Thirty patients who received cardiopulmonary bypass less than 120 minutes were enrolled into the control group(Group C).The incidences of complications were compared between two groups,the experience of cardiopulmonary bypass management (flow rate,perfusion pressure,infusion balance,etc.).Results There were 4 cases died in Group L.Eight cases had low cardiac output;2 cases had renal failure; 2 cases had DIC. 3 cases had positive blood culture.In group C,there were 5 cases died,and 11 cases had low cardiac output.Conclusion Our experience concluded that it is important to terminate the systemic inflammatory response syndrome early and well-organized cardiopulmonary management are two key elements to avoid complications.
