重型颅脑损伤患者常会出现中枢性高热,临床中多采用低温治疗和降温措施以改善患者的高热状态,因此患者体温的变化既反映了患者病情的变化,也反映治疗的效果。膀胱温监测作为重要的体温监测手段,由于其创伤小,可提供连续稳定的体温监测结果,操作简单、方便,被越来越多的应用于危重症患者的体温监测[1]。但此类患者由于肾脏的损伤或者使用脱水剂或利尿剂等造成患者尿量的变化,从而可能影响到膀胱温监测的效果。本研究主要探讨 Patients with severe craniocerebral injury often have central fever, the clinical use of hypothermia and cooling measures to improve the patient’s high fever, so the patient’s temperature changes reflect both the patient’s condition changes, but also reflect the effect of treatment. Bladder temperature monitoring, as an important means of temperature monitoring, can provide continuous and stable body temperature monitoring results because of its small trauma. It is simple and convenient to operate and is used more and more for temperature monitoring of critically ill patients [1]. But such patients due to kidney damage or the use of dehydration or diuretics caused by changes in patient urine, which may affect the bladder temperature monitoring results. This study mainly discusses
