目的：比较成人重型颅脑损伤患者的脑温与常规核心体温指标(直肠温度和膀胱温度)的差异。方法：对8例重型颅脑损伤患者的脑温与体温、膀胱温度的关系进行了研究。用埋入膀胱导管的热敏电阻测量总胆红素(TBL)，用直肠探头用热敏电阻测量总有效率(TRE)。每个患者的TBR和TBL之间的平均差异在0.32到1.9摄氏度之间，差异的标准差在0.30到0.80摄氏度之间。每个患者的TBR和TRE之间的平均差异在0.1到2.0摄氏度之间，差异的标准偏差在0.32到1.08摄氏度之间。在大多数患者中，在正常温度范围之外的温度范围内(TBR小于或等于36摄氏度和>；38摄氏度)。结论：创伤性脑损伤后，TBL和TRE经常低于TBR，特别是在患者体温过低或过高的情况下。
OBJECTIVE: The purpose of this study was to compare brain temperature (Tbr) with conventional indicators of core body temperature (i.e., rectal temperature [Tre] and bladder temperature [Tbl]), in adults with severe head injury.METHODS: The relationships between Tbr and Tbl and between Tbr and Tre are described in terms of differences in temperature in eight patients with severe head injury.INSTRUMENTATION: Brain tissue temperature was measured every minute, with a thermocouple embedded 2 cm from the tip of a ventriculostomy catheter used to measure intracranial pressure. Tbl was measured with a thermistor embedded in a bladder catheter, and Tre was measured with a thermistor in a rectal probe.RESULTS: Tbr was usually greater than Tbl and Tre. The average difference between Tbr and Tbl for each patient ranged from 0.32 to 1.9 degrees C, with standard deviations of the difference ranging from 0.30 to 0.80 degrees C. The average difference between Tbr and Tre for each patient ranged from 0.1 to 2.0 degrees C, with, standard deviations of the difference ranging from 0.32 to 1.08 degrees C. In the majority of patients, the differences (Tbr - Tbl and Tbr - Tre) were greater at temperatures outside of the normal temperature range (Tbr less than or equal to 36 degrees C and >38 degrees C).CONCLUSION: Tbl and Tre often underrepresent Tbr after traumatic brain injury, particularly when the patient is hypo- or hyperthermic.
