Lumbar Cistern Drainage In The Early Postoperation Of Aneurysmal Subarachnoid Hemorrhage

Objective:To evaluate the value of early continued lumbar cerebrospinal fluid drainage in treatment of aneurysmal subarachnoid hemorrhage.Methods:87 patients were randomly divided into two groups, group with repeated lumbar punctures (49 patients) and group with continued lumbar cerebrospinal fluid drainage (38 patients). All the patients were performed with clapping of aneurism and used conventional drugs after surgery. We compared the incidence of symptomatic vasospasm, chronic hydrocephaly, intracranial infection, the cleaning time of bloody cerebrospinal fluid and hospital stay of two groups, and assessed with GOS standard for the efficacy.Results:The incidence of symptomatic vasospasm, chronic hydrocephaly of the experimental group were 13.8%,8.2%, while the control group were 44.7%,23.6%, which was significantly above experiment group. The incidence of intracranial infection was 8.2%, while the control group was 2.6%, without significant difference (x2=0.40,p=0.27). The cleaning time of blood cerebrospinal fluid and hospital stay for experimental group were 7±1.3 days,23±1.8 days, and 11±1.2 days,28±2.3 days for control group. In GOS after half a year follow-up, the experimental group is better than control group, the rate of good recovery was 81.6%.Conclusion:Early continued lumbar cerebrospinal is a high efficiency, easy, controlled process, and it can decrease the occurrence of symptomatic vasospasm, chronic hydrocephaly, and the cleaning time of bloody cerebrospinal fluid and hospital stay of the patients were performed with clapping of aneurism.
