The opportunity and style of equipped with closed waist pool circulation drainage replacement of cerebrospinal fluid for subarachnoid hemorrhage

Objective To investigate the opportunity and style of equipped with closed waist pool circulation drainage replacement of cerebrospinal fluid for primarily subarachnoid hemorrhage(SAH).Methods 43 patients with severe primarily SAH were randomly divided into two groups:treatment group(n=21,treated with closed waist pool circulation drainage replacement of cerebrospinal fluid),control group(n=22,treated with intermittent replacement of cerebrospinal fluid),and blank group(23 patients with light-midrange SAH were treated with merely medicine expectant treatment).The observation tagets were National Institutes of Health Stroke Scale(NIHSS),activities of daily living(ADL),Glasgow Coma Scale(GCS),time of headache to relieve,time of subarachnoid blood to clear up,days in hospital,mortality rate and complication.Results After the treatment,NIHSS,ADL and GCS in the treatment group were 5.85±5.35,95.42±16.35,13.95±1.03,and those in the control group were 20.83±8.78,63.23±10.45,9.80±1.47 respectively.There were significant differences in them between both groups(P0.01).In the treatment group,incidence of cerebral vasospasm hydrocephalus was 23.81%(5/21)and 2 cases(9.5%)death,which was lower than that of 54.54%(12/22)and 4 cases(18.2%)death in the control group.There were also significant differences in them(P0.05).The time of Headache to relieve(5±1.38d),time of subarachnoid blood to clear up(3±1.6d),days in hospital(17±1.8d)in treatment group,lower than those of the control group(16±2.57d,8±2.5d,33±1.5d).There were significant differences in them between both the groups(P0.01).Incidence rate of rehaemorrhagia in the three groups were 14.29%(3/21),18.18%(4/22),21.74%(5/23)respectively,there were no significant differences(P0.05).Conclusion The closed drainage and displacement of CSF through terminal cistern are the simple,safe and effective methods to treat SAH,can reduce incidence rates of cerebral angio spasm and chronic hydrocephalus.and improve patients' living ability.Don't increase the risk of rehaemorrhagia.
