Secondary insults are known to worsen outcome following traumatic brain injury (TBI). Though there is conflicting clinical evidence with regards to hyperthermia, it is generally considered as detrimental and for patients that exhibit pyrexia it is important temperature control. In animal models there is no question about the role of hyperthermia and its detrimental effect on outcome. In our study there was a significant increase in macrophage influx to the brain following TBI and moderate hyperthermia.
