Objective To explore the effectiveness and safety of exchange of cerebrospinal fluid in the treatment of subarachnoid hemorrhage (SAH). Methods Sixty SAH patients diagnosed by CT and lumbarpuncture were randomly assigned into a control group (n =30, received conventional treatment) and a treatment group (n =30, received exchange of cerebrospinal fluid plus conventional treatment). The main complications and effectiveness between the two groups were compared. SPSS 10.0 was used for statistical analysis. Results Compared with the control group, complications of persistent headache ( P =0.002 and 0. 007 respectively), cerebral vasospasm ( P =0. 028 ) and hydrocephalus ( P =0. 038 ) were fewer in the treatment group. No significant difference in the incidence of rehaemorrhagia was found between the two groups (P = 1. 000). Better effectiveness was observed in the treatment group (RR. 3.00, 95% CI 1. 014 to 8. 880, P = 0. 044 ). Conclusions Exchange of cerebrospinal fluid plus conventional treatment is more effective than conventional treatment alone in the treatment of SAH.
目的:研究脑脊液置换术治疗蛛网膜下腔出血的效果。方法:蛛网膜下腔出血79例为治疗组及30例对照组,给予常规药物治疗,治疗组在此基础上增加脑脊液置换疗法。结果:治疗组疗效优于对照组、治疗有效率及死亡率上差异均有显著。 结论:脑脊液置换术对蛛网膜下腔出血具有较好的疗效,值得进一步推广。
