Using of Ommaya reservoir in postoperative intracranial infection combined with hydrocephalus in patients with severe traumatic brain injury / 中国医师进修杂志

ABSTRACT

Objective To investigate the treatment function and dominance of Ommaya reservoir,which was used to treat postoperative intracranial infection combined with hydrocephalus in patients with severe traumatic brain injury. Methods Thirty-four patients suffered intracranial infection combined with hydrocephalus after operations. They were randondy divided into 2 groups.Thirleen patients were treated with Ommaya reservoir, the others were treated with external ventricular drainage. The 24-hour mean drain quantum, the mean days from implantation pumps or htbes to ventriculo-peritoneal (V-P) shunt operation,the rate of secondary operation and the rate of getting V-P shunt operation were analyzed, then the Glasgow outcome scale ( GOS ) of patients were observed at 3 months. Results Compared with patients treated with external ventriular drainage, patients with Ommaya reservoir had the less24-hour mean drain quantum and shorten time to get the V-P shunt operation,the mean days from implantation pumps to get V-P shunl was(57.00 ± 8.06) days. In 13 patients with Ommaya reservoir, 10 patients finished V-P shunt operation finally,3 patients gave up the shunt operation, shunt rate was 76.9%.In the treatment period , 4 patients had to change the Ommaya reservoir, secondary operation rate was 30.8%. Thirteen patients had the chance to get V-P shunt operation among 21 patients which got external ventricular drainage, 3 patients gave up the shunt operation, 5 patients died, shunt rate was 61.9%, 16 patients changed the ventricular drainage tube, sec-ondary operation rate was 76.2%. There was no significant difference in 3-month GOS between them (P ＞0.05 ). Conclusions Compared with external ventricular drainage, Ommaya reservoir has similar shunt rate.Ommaya reservoir has the less secondary operation rale, shorten the treatment days postoperative intracranial infection combined with hydrocephalus in patients with severe traumatic brain injury, so it should be popularized in clinic.
