Monitoring the central peripheral temperature gradient in critically ill surgical patients is a simple, sensitive, noninvasive and inexpensive method that can accurately reflect the state of peripheral circulation. It serves as an early warning sign, and its return to normal is a good measure of the efficacy o f therapy. Recognition of the cause of an abnormal gradient is essential to successful management since it can result from pain as well as hypovolemia. Warm-up patterns vary, and every patient should be treated individually. Forcing vasodilatation is usually unnecessary and amy be dangerous in hypothermic patients and in patients with hypovolemia if blood volume is not corrected simultaneously. Peripheral vascular disease, central hypothermia and the use of vasoactive drugs limit the usefulness of this method.
监测危重症外科患者的中心-外周温度梯度是一种简单、灵敏、无创且经济的方法，能够准确反映外周循环状态。它可作为一种预警信号，其恢复正常是衡量治疗效果的良好指标。识别异常梯度的原因对于成功治疗至关重要，因为它可能由疼痛以及血容量不足引起。升温模式各不相同，每位患者都应进行个体化治疗。强迫血管扩张通常没有必要，而且在体温过低的患者以及血容量未同时纠正的低血容量患者中可能是危险的。外周血管疾病、中枢性体温过低以及血管活性药物的使用限制了该方法的实用性。
