RESUMO
Objective To study the effect of mild hypothermia on MBP level in the CSF of TBI patients.Methods We investigated 36 patients with severe traumatic brain injury and randomized them into two groups,mild hypothermia treatment group and normathermia treatment group.The MBP levels in CSF and ICP and GOS scores in different time-points were evaluated.Results There was no significant difference between the two groups in the MBP level on the 1st day after treatment(P ＞ 0.05).The MBP levels in mild hypothermia group decreased greater than that in the control group on the 7th and 14th day after treatment(P ＜ 0.05).ICP decreased more in mild hypothermia group than in the control group(P ＜ 0.05)on the 7th and 14th day after treatment.Moreover,patients in mild hypothermia treatment group have better outcome than those in the control group(P ＜ 0.05),but there was no significant difference in the death rate between the two groups.Conclusion Mild hypothermia may provide neuroprotection by reducing MBP degradation and stabilizing medullary sheath,thus improving the prognosis of TBI patients.
RESUMO
Objective To study the effect of mild hypothermia on β2- microglobulin (MG) level in cerebrospinam(CSF) of traumatic brain injury (TBI) patients.Methods Thirty-six severe TBI patients were divided into two groups randomly,mild hypothermia treatment group and normathermia treatment group,and the β2- MG level and GOS score in CSF of these patients in different time- point were evaluated.Results β2-MG level increased at first,then decreased gradually,and MBP level in mild hypothermia group decreased greater than the control group( P ＜ 0.05 ),moreover,patients in mild hypothermia treatment group had better outcome than the control group( P ＜ 0.05).Conclusion Mild hypothermia may act as neuroprotection by inhibiting inflammatory response or improving immune regulation.
