Intracranial temperature and its normal variation, as well as its response to various pathologic conditions, has become a critical component of monitoring in neurosurgical intensive care. In a prospective clinical study of 54 neurosurgical patients, intracranial pressure, cerebral perfusion pressure, and intraventricular and systemic temperatures were monitored in a neurosurgical intensive care unit. All of our patients' intraventricular temperatures were initially higher than their systemic temperatures. In 11 patients, the intraventricular temperature became lower than the systemic temperature, in a median time of 4.43 hours (range, 4.21-5.18 hours), prior to any changes in intracranial and cerebral perfusion pressures. Reversal of the disassociation between intraventricular and systemic temperatures may be an early marker of patients with a poor prognosis.
颅内温度及其正常变化，以及其对各种病理状况的反应，已成为神经外科重症监护中监测的关键组成部分。在一项对54例神经外科患者的前瞻性临床研究中，在神经外科重症监护病房监测了颅内压、脑灌注压以及脑室内和全身温度。我们所有患者的脑室内温度最初均高于其全身温度。在11例患者中，在颅内压和脑灌注压出现任何变化之前，脑室内温度在中位时间4.43小时（范围4.21 - 5.18小时）时变得低于全身温度。脑室内和全身温度之间解离的逆转可能是预后不良患者的早期标志物。
