The purpose of the study was to identify extracranial locations in which temperature changes in humans reflect those of intracranial temperature in a reliable and repeatable way. This was achieved by subjecting 14 non-anaesthetized patients after neurosurgery to face fanning while intracranial and extracranial temperatures were continuously measured. In all patients the cranium was closed and the group included both febrile and non-febrile as well as hyperthermic and normothermic patients. The patients' faces were fanned for 20-30 min, with a small fan at an air speed of 3.25 m s(-1). This gave intracranial temperature changes measured in the subdural space ( T(sd)) that were highly and significantly correlated ( r=0.91, P<0.05, n=14) with changes in tympanic temperatures ( T(ty)). A low, statistically insignificant correlation ( r=0.40, P>0.05, n=12) was found between T(sd) and oesophageal temperatures. In conclusion, intracranial temperature changes, induced by face fanning, were reliably reflected by the changes in T(ty).
本研究的目的是确定人体颅外的一些部位，其温度变化能够以可靠且可重复的方式反映颅内温度。通过对14例神经外科手术后未麻醉的患者进行面部扇风，并持续测量颅内和颅外温度来实现这一目的。所有患者的颅骨均已闭合，该组包括发热和不发热以及体温过高和体温正常的患者。用一个小风扇以3.25米/秒的风速对患者面部扇风20 - 30分钟。这使得在硬膜下间隙测量的颅内温度变化（T(sd)）与鼓膜温度变化（T(ty)）高度显著相关（r = 0.91，P < 0.05，n = 14）。T(sd)与食管温度之间存在低相关性，且无统计学意义（r = 0.40，P > 0.05，n = 12）。总之，面部扇风引起的颅内温度变化可由T(ty)的变化可靠地反映出来。
