亚低温治疗重型颅脑创伤急性期患者脑温与直肠温度的测量观察

A study of the relationship between brain and rectal temperature of patients in acute phase of severe traumatic brain injury during the treatment of mild hypothermia

目的：探索一种简便、安全且准确、可靠的测温方法以替代直接监测脑温（BT）的方法。方法：52例重型颅脑创伤（STBI）急性期患者（GCS≤8分）于亚低温治疗中,同时测定无明显损伤侧膜下27～36 mm处额叶脑白质温度及距肛门10 cm处直肠内温度（RT）。结果：BT与RT呈良好的直线相关关系,依据RT监测数据,以相应回归方程可较准确地以RT估算BT。在不同温度范围内,BT与RT之间的差距不同,异常温度范围内（发热和亚低温状态下）,BT与RT之间的差距增大。结论：简便、无创、安全、对设备技术条件要求较低的RT监测,可作为替代BT直接监测的可靠手段在临床推广应用。

Objective： To explore a simple,safe and reliable way to evaluate brain temperature（BT） with rectal temperature（BT） accurately.Method： 52 patients in acute phase of severe traumatic brain injury（STBI）,with a GCS of 8 or less,monitored of BT at the non-injured frontal white matter,27-36 mm below the dura;and RT was continuously measured at 10 cm into the rectum at the same time during the treatment of mild hypothermia.Result： A good correlation between BT and RT could be seen.According to the corresponding regression equation,BT could be evaluated with RT correctly.Conclusion： The measurement of RT may be an alternative way for monitoring of BT to be used in clinical work in term of the simplicity,safety,non-injury,and economization of the RT measurement.
