To observe the curative effect of subdural effusion treated and prevented with bandage secondary to decompressive craniectomy performed in patients with traumatic brain injury.

55 cases of traumatic brain injury were undergone decompressive craniectomy from September 2009 to April 2015 in department of neurosurgery of the second people’s hospital of Jingzhou, and those cases were randomly divided into bone window compression bandage group(n=26) and normal group (n=29). Analysis the difference of the incidence of subdural effusion, the occurrence time and postoperative GOS score between two groups. And observation the curative effective of subdural effusion treated with bone window compressive bandage.

The incidence of subdural effusion post decompressive craniectomy is 7.7%(2/26) in bandage group, 27.6%(8/29) in normal group, the average appear time of subdural effusion post decompressive craniectomy in bandage group (38.5±3.7) d is longer than normal group(13±2.9) d, there are significant differences between two groups(P<0.05). The number of GOS score >3 was 18(69.2%) in bandage group, 21(73.2%) in normal group, there is no significant difference between two groups(P>0.05). After average 23.9 d bandage treatment, the subdural effusion of 10 cases were absorbed disappear, there was no case needed operation.

Bone window compression bandage after decompressive craniectomy performed in patients with traumatic brain injury can obviously reduce the incidence of subdural effusion, and it played an import role in preventing and treating the subdural effusion. This method is simple, safe, and effective, and it is worthy of clinical application.
