Abstract:
Objective To study the effects of mild hypothermia on secondary cerebral vasospasm and levels of endothelin (ET),calcitonin gene related peptide (CGRP) in cerebrospinal fluid (CSF)and plasma in patients with severe brain injury(SBI).Methods Sixty-five patients with SBI were randomly divided into mild hypothermia group(30 cases)and control group(35 cases).Based on the routine treating method,the patients of mild hypothermia group were treated with local mild hypothennia.The levels of ET,CGRP in CSF and plasma were detected before and after treatment.And the incidence rates of secondary cerebral vasospasm cases were compared between the two groups.Results (1)At 7,14 day after treatment,ET levels in CSF and plasma in mild hypothermia group were significantly lower than these in control group (P＜0.05or＜0.01).The CGRP levels in CSF and plasma were the lowest at 7 day,then gradually increased in two groups.However,the CGRP levels in mild hypothermia group at 7,14 day were higher than those in control group (P＜0.05 or＜0.01).(2) The rate of secondary cerebral vasospasm in mild hypothermia group was 6.67% which significantly less than that in control group (22.86%) (P＜0.05).Conclusion Mild hypothermia can prevent the increasing of ET and the decreasing of CGRP in CSF and plasma,and decrease the incidence rate of secondary cerebral vasespasm in patients with SBI.
