The effect of induced normothermia on the outcomes of severe traumatic brain injury patients at Boston Medical Center

The objective of this work was to evaluate the efficacy of an induced normothermia protocol by comparing patient mortality and outcomes in patients treated at Boston Medical Center (BMC) before and after the implementation of the protocol. The controls (regular fever management) and the cases (induced normothermia) were demographically similar, except there were more whites (p = 0.01) in the control group and more of the patients in the control group were transferred to BMC from outside hospitals (p = 0.006), although there was not a higher incidence of death among patients who were transferred from outside hospitals (p = 0.55). The patients in the case group were kept normothermic throughout the first 7 days of their hospital stay more effectively than those in the control group (p = 0.0001). Average intracranial pressure (ICP) and cerebral perfusion pressure (CPP) were not different between the two groups, although mean arterial pressure (MAP) was (p = 0.84; p = 0.08; p = 0.02, respectively). Mortality was lower in the case group by hospital discharge (p = 0.007) and patients in the case group were more likely to achieve a positive functional outcome (p = 0.03). In light of these findings, there is a need for high-quality prospective trials to assess the efficacy of induced normothermia compared to regular fever management.
