Abstract
BACKGROUND: We aimed to assess the effects of pre-hospital mild therapeutic hypothermia (MTH) on patients with severe traumatic brain injury (sTBI). METHODS: Eighty-six patients with sTBI were prospectively enrolled into the pre-hospital MTH group and the late MTH group (initiated in hospital). Patients in the pre-hospital MTH group were maintained at a tympanic temperature of 33°C-35°C before admission and continued to be treated with a therapeutic hypothermia device for 4 days. Patients in the late MTH group were treated with the same MTH parameters. Intracranial pressure (ICP), complications and Glasgow Outcome Scale (GOS) scores were monitored. RESULTS: ICP was significantly lower for patients in the pre-hospital MTH group 24, 48, and 72 h after treatment (17.38 ± 4.88 mmHg, 18.40 ± 4.50 mmHg, and 16.40 ± 4.13 mmHg, respectively) than that in the late MTH group (20.63 ± 3.00 mmHg, 21.80 ± 6.00 mmHg, and 18.81 ± 4.50 mmHg) (P < .05). The favorable prognosis (GOS scores 4-5) rate in the pre-hospital MTH group was higher tha n the late MTH group (65.1% vs. 37.2%, respectively; P < .05) without complications . CONCLUSION: Pre-hospital MTH for patients with STBI can reduce ICP and improve neurological outcomes.
