摘要
目的与方法:观察了40例择期心内手术患者及30例普外择期手术患者围术期血清TNF-α水平变化。结果:心内手术后2周内患者细胞免疫和红细胞免疫功能被明显抑制,而血清肿瘤坏死因子TNF-α明显升高,若合并严重感染后则进一步升高,但普外手术组上述参数变化与术前相比无统计学意义。心内手术术后严重感染率33%,MSOF发生率7.5%,而血清TNF-α水平与感染性并发症发生率呈正相关(P<0.01),普外手术组术后严重感染率仅6%。结论:心内手术后患者严重的细胞和红细胞免疫功能障碍是导致严重感染的最直接原因之一,而严重感染者血清TNF-α水平急剧升高是引发MSOF的机理之一。
bjective and Methods:A comparative study between the patients scheduled for cardiopulmonary bapass (CPB) and those underwent selective general surgary was carried out.Results: Experimenmtal data show that cell mediated and erythrocytic immunity were both siginificantly inhibited within two weeks after CPB,which was accompanied with a sharp rise of blood level of tumor necrosis factor alpha(TNF).The concentration of TNF alpha was increased to the highest level if the patient was complicated by severe infection.On the contrary,no statisical difference was discovered between preand postoperative values of the parameters mentioned above in general surgery group after operation.Serious infectious rate of 325%,morbility of multiple system organ failure(MSOF) of 75%,and a linear regression between serum level of TNF alpha and incidence of severe infection were observed in CPB group.Conversely,in general surgery group serious infection rate was only 6%.Conclusion:It is concluded that serious cellular and erythrocytic immunodepression is the direct reason for resulting in severe infection after CPB,and a high level of TNF alpha in serum is one of the mechanisms of MSOF.
