Methods: A total of 78 patients with severe craniocerebral injury who underwent emergency treatment in Huanggang Central Hospital between September 2015 and May 2017 were selected as the research subjects and divided into control group (n=39) and mild hypothermia group (n=39) by random number table. Control group received clinical standard large trauma craniotomy for severe craniocerebral injury, and mild hypothermia group received routine surgery and postoperative mild hypothermia therapy. The cerebral oxygen metabolism and brain injury in two groups of patients were detected immediately after admission (T0), 1 week after treatment (T1) and 4 weeks after treatment (T2). Results: At T0, there was no statistically significant difference in the levels of cerebral oxygen metabolism indexes, cerebral blood flow parameters and brain injury markers between the two groups. At T1 and T2, PO2 levels in mild hypothermia group were higher than those in control group while Da-jvO2 levels were lower than those in control group;cerebral blood flow parameters Vs and Wv levels were higher than those in control group while PI levels were lower than those in control group;brain injury markers MBP, AQP-4 and S-100B contents were lower than those in control group while BDNF contents were higher than those in control group. Conclusion: Adjuvant mild hypothermia therapy after routine surgery may further reduce the cerebral oxygen metabolism and relieve the brain injury in patients with severe craniocerebral injury.展开更多

Methods: Thirty-eight patients with acute severe head injury were treated with mild hypothermia, meantime PbrO2, PbrCO2, pHbr and BT were monitored in order to study the changes of PbrO2, PbrCO2, pHbr and BT. Results: In patients with acute head injury, mild hypothermia obviously increased PbrO2, decreased PbrCO2 and CO2 accumulation and acidosis in brain tissue. BT was 1℃-（1.5）℃ higher than rectal temperature（RT） after injury. The BT and RT were decreased when the patients were treated with mild hypothermia, but at the same time the difference between BT and RT was increased. Conclusions: In patients with acute severe head injury the direct monitoring of PbrO2, PbrCO2, pHbr and BT was safe and reliable, and is helpful in estimating prognosis and mild hypothermia therapy.展开更多
