Abstract:

Objective To investigate the effect of constant temperature blankets on intravascular hypothermia for severe traumatic brain injury (sTBI). Methods A total of 112 inpatients with sTBI from January, 2013 to December, 2018 were reviewed. They were divided into control group (n = 58) and observation group (n = 54) according to whether a self-warming blanket was used. They were assessed with Bedside Shivering Assessment Scale (BSAS). Their dosages of anti-shivering medicine, coagulation and intracranial pressure were recorded. The scores of Glasgow Outcome Scale Extended (GOSE) and the mortality one, six and twelve months after discharge were observed. Results The incidence and severity were less in the observation group than in the control group (χ2 = 16.212, P < 0.01). The dosage of anti-shivering medicine was less in the observation group than in the control group ( t > 1.269, P < 0.05). The hypercoagulation relieved significantly six hours after hypothermia in the observation group, and it was stable twelve hours after hypothermia. For the control group, the hypercoagulation relieved significantly twelve hours after hypothermia, and it was stable 24 hours after hypothermia. The intracranial pressure decreased more in the observation group than in the control group. The GOSE score and the mortality were less in the observation group than in the control group ( t > 1.168, P < 0.05) one, six and twelve months after discharge. Conclusion Application of self-warming blankets in intravascular hypothermia for sTBI may relieve shivering, hypercoagulation and intracranial pressure, to improve the outcome of patients.
