The influence of brain temperature (Tbr) on outcome in neuro-critical care (NCC) patients is currently poorly understood (for review see [1, 2]). Studies can be cited that point in either direction; that a high temperature [3] or a low temperature [4] is an indicator of poor prognosis. As Tbr is not measured routinely in NCC, body temperature (Tb) is used as a surrogate for intracranial temperature. However, differences between Tbr and Tb, can occur which are often very subtle (often smaller than the <0.5°C) [5, 6] so the performance, or even the positioning of the temperature sensor placed within the brain or peripheral sites (e,g, rectum) becomes important. In short, are the subtle differences observed between Tbr and Tb `real' or due to measurement error? The aim of this study was to assess performance and measurement uncertainty of the body and brain temperature sensors currently used in neurocritical care.
