Brain Tissue Temperature Measurements in Clinical Setting

  • Nariyuki Hayashi

Abstract

Clinical data are available that indicate that body temperature and brain temperature can differ significantly and that there are temperature gradients within the injured brain. In head injured patients, brain temperature readings are commonly elevated compared with core temperature [1, 2, 3, 4, 5, 6]. Sternau and colleagues [6] first directly measured brain temperature in head injured patients and reported transient periods of hyperthermia at variable periods after injury. Hayashi and colleagues [1] reported the elevation of brain tissue temperature up to 42°–44°C as brain thermo-pooling phenomenon after trauma. The mechanism underlying this brain thermo—pooling phenomenon is dependent upon several factors including core temperature, cerebral perfusion pressure, cerebral blood flow, and brain metabolism. Therefore, the elevation of brain temperature to levels greater than 38°C occurs with reduced systolic blood pressure (<90–100mmHg), reduced cerebral perfusion pressure (<65–75 mmHg), and cerebral blood flow disturbances.
