高龄发热患者物理降温后复测体温最佳时间点探讨

Exploration of the best time of retest elderly patients' temperature after physical cooling

目的 探讨高龄发热患者运用各种物理降温法降温后,复测体温的最佳时间点.方法 收集2011年3月至2013年3月采用物理降温的高龄发热患者196例,测量基础体温（T0）及降温后30 min（T1）、60 min（T2）、90 min（T3）、120 min（T4）的体温,分别计算T1：0～30 min、T2：31～60min、T3：61～90 min、T4：91 ～ 120 min高龄发热患者的降温速率,找到患者物理降温效果最佳时间点.结果 冰毯降温患者T1 ～2平均体温下降幅度最大,温水及酒精擦浴患者T2～3平均体温下降幅度最大,冰袋降温患者T3～4平均体温下降幅度最大.结论 由于高龄发热患者代谢水平低、循环慢等因素,各种物理降温最佳时间均大于降温后30 min;不同物理降温方式的接触面积及时间不同,因此复测体温最佳时间也不同.

Objective To explore the best time of retest elderly patients＇temperature after various physical cooling. Methods Totally, 196 elderly patients with hyperpyrexia from March 2011 to March 2013 were received physical coaling to control temperature, who were tested the baseline body temperature （ TO ） and temperatures of 30 minutes after cooling （ T1 ） ,60 minutes after cooling （T2） ,90 minutes after cooling （ T3 ） , and 120 minutes after cooling （T4）. The tempera- tures were analyzed to find the best time of retest patients temperature after different physical cooling. Results For the patients who used ice cooling blanket, TI 2 was the best time of retest temperature. For the patients who bad a bath with warm water or alcohol, T2 - 3 was the best time of retest temperature. For the patients who used ice bag, T3 - 4 was the best time of retest temperature. Conclusion Due to the reasons of low metabolism level and slow circulation of elderly patients, the best time retest temperature is more than after colling 30 minutes. The contact area and time of different physical cooling is different, the best time retest temperature is also different.
