Temperature monitoring with zero-heat-flux technology in neurosurgical patients
- 7 Downloads
With great interest and enthusiasm we read the interesting article of Pesonen et al.  recently published in the journal about the measurement of core temperature with the new non-invasive zero-heat-flux thermometer (3M Bair-Hugger). Although the device has been validated in many patient groups undergoing cardiac surgery [2, 3], vascular surgery , gynecological and trauma surgery , abdominal surgery  and during intensive care  it had not yet been validated in patients undergoing neurosurgery. Therefore the authors work is valuable because the measurement of the zero-heat-flux thermometer can be disturbed in many ways in patients undergoing neurosurgical procedures.
Because the temperature sensor is located directly near the operative field the measurements may be influenced by washing and draping, the heat coming from the operating room lights or the drilling of the bone . Furthermore craniotomy is associated with detachment of the brain from the cranium...
