心脏瓣膜替换术后147例死亡患者营养状况分析

目的：对心脏瓣膜替换术后死亡患者营养状况进行评价。方法：用回顾性调查法分析１４７例死亡患者的多项营养指标。结果：体重评价提示约８０．０％患者入院时及手术前有营养不良。入院后大部分患者体重降低，入院时平均体重为４９．２ｋｇ，术前为４５．８ｋｇ，１１９例体重下降。多数患者Ｈｂ低于正常值，总蛋白和白蛋白在入院之后有所改善。有些患者有电解质紊乱及肝肾功能障碍。单因素Ｌｏｇｉｓｔｉｃ回归模型分析结果提示多器官功能衰竭、肝肾功能不全、营养不良等与心脏瓣膜替换术后患者死亡相关。结论：心脏瓣膜替换术死亡患者在手术前后普遍存在较为严重的营养不良，这可能是影响术后机体恢复、促使术后多种并发症和器官衰竭发生，从而引起死亡的因素之一。
