Application of continuous drainage of cerebrospinal fluid by remaining a tube after lumbar puncture in prevention and treatment of traumatic cerebrovascular spasm

Objective To study the curative effect of continuous drainage of cerebrospinal fluid (CSF) through a tube remained in lumbar in the treatment of cerebrovascular spasm (CVS) after subarachnoid hemorrhage (SAH). Methods 88 SAH patients were randomly divided into 2 groups: control group (48) with conventional therapy and lumbar puncture and treatment group (40) with conventional therapy and CSF continuous drainage by remaining a tube after lumbar puncture. Results The recovery time of CSF pressure and erythrocyte count in the treatment group is faster than that of control group (P0.05). The incidence rates of spasticity index at different time, brain infarct and death in the treatment group are obviously lower than those of the control group (P0.05). There was no significant difference in view of re-hemorrhage rate between the two groups (P0.05), but significant difference of therapeutic efficacy between the two groups in GOS when leaving the hospital (P0.05). Conclusion CSF continuous drainage by lumbar puncture and remaining a tube is not only of confirmative effect in the treatment and prevention of CVS after SAH, but also promotes speedy rehabilitation of nerve functions and adds no risk of re-hemorrhage.
