目的 探讨低体温风险分级干预在经皮肾镜取石病人围手术期的应用效果。

方法 选取经皮肾镜取石术病人76例，随机分为观察组和对照组各38例。观察组应用低体温风险分级干预方案进行护理，对照组给予常规护理，观察2组病人术前和术中30、60、90、120 min以及术后的体温情况和寒战的发生率。

结果 2组病人术前和术中30 min的体温差异均无统计学意义( P >0.05)，观察组术中60、90、120 min及术后的体温均高于对照组( P < 0.05~ P < 0.01)。观察组病人术后寒战发生率为7.89%(3/38)，低于对照组病人术后寒战发生率26.32%(10/38)( P < 0.05)。

结论 低体温风险分级干预应用在经皮肾镜取石病人围手术期，可以早期预测术中低体温的高危人群并给予保温措施，减少病人术后低体温的发生。

Objective To explore the application effects of hypothermia risk grading intervention in perioperative period of patients treated with percutaneous nephrolithotomy.

Methods Seventy-six patients treated with percutaneous nephrolithotomy were randomly divided into the observation group and control group(38 in cases each group).The hypothermia risk grading intervention program was given in the observation group for nursing, while the routine nursing was given in the control group.The temperature and incidence rate of shivering in two groups were observed before operation, at 30, 60, 90 and 120 min during operation and after operation.

Results There was no statistical significance in the body temperature between two groups before operation and at 30 min during operation( P >0.05).The body temperature in observation group was higher than that in control group at 60, 90 and 120 min during operation and after operation( P < 0.05 to P < 0.01).The incidence rate of postoperative shivering in observation group was 7.89%(3/38), which was lower than that in control group(26.32%)(10/38)( P < 0.05).

Conclusions The application of hypothermia risk grading intervention in the perioperative period of patients treated with percutaneous nephrolithotomy can early predict the high-risk group with intraoperative hypothermia, and the thermal insulation measures can reduce the occurrence of postoperative hypothermia.
