Objective To evaluate the curative effect and safety of mild hypothermia on patients with traumatic brain injury. Methods According to the cochrane systematic review methods , the data bases such as Cochrane, Pubmed, Embase, CBM, CNKI, Wanfang and VIP database were searched. The quality of included documents were assessed to extract meta analysis data. Results Compared to the control group, there was no statistically significant difference in patients treated by hypothermia for 3 days or less in mortality , but the difference was statistically significant after the summary [RR=0.74, 95%CI 0.64~0.85,P<0.000 1]; And there was no statistically significant difference in improving neural function of patients treated by hypothermia for < 3 days , but hypothermia improves the prognosis after the summary [RR=1.40,95%CI 1.24~1.59,P<0.000 01]. The difference was statistically significant in the incidence of pneumonia (P=0.007), there was no statistically significant difference in the incidence of arrhythmia (P=0.06), but the difference was statistically significant after sensitivity analysis. Conclusions Patients treated by hypothermia for < 3 days is not valid for clinical outcomes , the duration of the treament up to 3 days may not reduce mortality rates, but can improve the prognosis, lasts longer than 3 days or until the pressure back to normal, reducing the mortality rate, improve the neurological prognosis;but increased incidence of pneumonia, whether to increase the rate of cardiac arrhythmias have yet to be determined.
