外伤性硬膜下积液术后复发的相关因素分析

目的 探讨外伤性硬膜下积液（TSE）术后复发的危险因素。方法 回顾性分析2011年1月至2015年6月收治的138例TSE的临床资料，采用Logistic回归分析检验术后复发的危险因素。结果 术后复发36例，发生率为26.09%；复发时间为18~92 d，平均（36.2±10.6）d。多因素Logistic回归分析结果显示年龄≥60岁,进展型硬膜下积液以及使用脱水剂是TSE术后复发的独立危险因素（P<0.05）。结论 TSE术后复发率较高，以老年,进展型硬膜下积液,使用脱水剂的患者为多见。

Logistic regression analysis of factors related to postoperative recurrence of traumatic subdural effusion

Objective To explore the risk factors relate to postoperative recurrence of traumatic subdural effusion (TSE). Methods The clinical data of 138 patients with TSE treated from January, 2011 to May 2015 were reviewed. The risk factors related to postoperative recurrence of TSE were analyzed by univariate and multivariate logistic regression analysis. Results TSE recurred (36.2±10.6) days (from 18 to 92 days) after the operation in 36 patients. The rate of TSE recurrence rate was 26.09%. The univariate analysis showed that the factors related to postoperative recurrence of TSE included age, thickness of effusion, type of effusion, midline shift, brain contusion hemorrhage and usage of dehydrant (P<0.05). The multivariate logistic regression analysis revealed that the independent risk factors related to postoperative recurrence of TSE included older than 60 years, progressive effusion and usage of dehydrant (P<0.05). Conclusions TSE may easily recur after the operation in the patients who are over 60 years, or suffer from progressive effusion or receive dehydrant treatment.
