重度营养不良患者围手术期的高危因素分析

目的探讨影响重度营养不良患者预后的高危因素。方法分析我院全军肛肠外科中心 1998～2004年收治的16例需手术治疗的合并重度营养不良患者的临床特征,对影响患者预后的多种因素进行单因素及多因素分析。结果 16例患者中,手术后1月内病死3例,3个月内病死6例。最长生存 3.5年,平均生存时间9.53月。单因素分析表明,病变的病理类型、输血量、术岳血小板下降为影响预后的因素；多因素回归分析显示,输血量、术后患者有无血小板下降为影响预后的独立因素。结论影响16 例重度营养不良患者预后的因素为术后病理类型、输血量、术后血小板下降。其中独立影响因素为输血量及术后血小板下降。

Studies on perioperative high-risk factors of the severe malnutrition patients

Objective To investigate factors influencing prognosis of patients with severe malnutrition. Methods Clinical data of 16 patients with severe malnutrition treated in our hospital were analyzed, and univariate and multivariate analysis was used to determine the prognostic factors. Results In all the 16 patients, 3 died within 1 month, 6 died within 3 months postoperatively; the longest survival span was 3.5 years and the average survival span was 9.53 months. Life Tables and Kaplan-Meier estimates showed that type of prognosis factor, tranfusion volume, blood platelet drop were the predictors of survival. Multivariate analysis showed that only blood platelet drop, tranfusion volume were the independent prognostic factors. Conclusion The survival of patients with severe malnutrition is related to type of prognosis factor, tranfusion volume, blood platelet drop; but tranfusion, blood platelet drop just are independent prognostic factors.
