In TRH treated group. the treatment was started with abolus injection of 0. 2 mg/kg followed by continuous infusion for 2 hours at 0. 2 mg/kg/h. Such treatment wasgiven once a day for 4 times. The patients in control group were given the equivalent normal saline with the samemethod. Results: TRH, administered intravenously after head injury. promoted the recovery of consciousness andGCS score, alleviated the traumatic brain edema, controlled and lowered the intracranial pressure. decreased thelevel of lipid superoxides, decreased the mortality rate. and improved the life quality of the survivals. Nocomplications or adverse and toxic effects were noted during the course of TRH treatment. Conclusion: TRH hasbeneficial effects on patients with severe head injury.展开更多
