急性硬膜下血肿手术时机对预后的影响

Influence of operative timing on prognosis of acute subdura! hematoma

目的研究手术时机对急性硬膜下血肿预后的影响。方法收集了202例接受手术治疗的急性硬膜下血肿患者，统计分析伤后2、4、6、8h等时间为界限的死亡率和功能生存率。结果各个时间界限的死亡率和功能生存率差异无统计学意义，但是随着受伤至手术间隔时间的延长，死亡率呈现出逐渐增加、功能生存率逐渐降低的趋势。并且，死亡患者的受伤至手术时间要显著大于生存患者。结论急性硬膜下血肿手术时机对预后有潜在的影响。符合有手术指征的患者，急性硬膜下血肿需要尽早手术清除血肿。

Objective To study the influence of operative timing on prognosis of acute subdural hematoma（ASDH）. Methods The data of 202 cases of ASDH subject to surgical operations were collected. The mortality and rate of functional survival were analyzed at the 2nd,4th,6th, and 8th h after operation. Results No significant difference in mortality and rate of survival was found among different time points. But there was a clear trend that the shorter the operative timing the lower mortality and more increased rate of functional survival. In addition,the mean time from injury to operation in non - survivors was significantly longer than survivors. Conclusion Operative timing has potential influence on the prognosis of ASDH. Evacuation of ASDH needs to be done as soon as possible on the emergence of indication of operation.
