Comparative study on the impact of warming blanket rewarming and natural rewarming on coagulation function in pediatric patients with severe hypothermia
恒温毯复温与自然复温对儿科重症低体温症患者凝血功能的影响研究

摘要

目的 本研究主要探讨恒温毯复温与自然复温对儿科重症低体温症患者凝血功能的影响，以为重症监护室低体温治疗策略的优化提供依据。方法 选择某院重症监护室收治的低体温儿科患者58例，随机分为研究组和对照组，每组29例。研究组采用恒温毯复温，对照组采用自然复温。比较两组患者护理前后的体温变化及血液凝血功能指标，包括凝血活酶时间（ACT）、血浆凝血酶原时间（PT）、凝血酶时间（TT）及纤维蛋白原（FIB）水平。结果 结果表明，研究组患者的平均体温显著高于对照组；在凝血功能方面，研究组护理后的凝血活酶时间、血浆凝血酶原时间及凝血酶时间均显著延长，而纤维蛋白原水平明显降低，与护理前相比改善明显，且均优于对照组（P<0.01）。结论 恒温毯复温较自然复温能有效升高低体温儿科患者的体温，明显改善患者的凝血功能。

Abstract

Objective This study primarily investigates the impact of warming blanket rewarming and natural rewarming on the coagulation function of pediatric patients with severe hypothermia, aiming to provide a basis for optimizing hypothermia treatment strategies in the intensive care unit.
Methods A total of 58 pediatric patients with hypothermia admitted to the intensive care unit of a hospital were selected and randomly divided into the study group and the control group, with 29 cases in each group. The study group used warming blanket rewarming, while the control group used natural rewarming. The changes in body temperature and blood coagulation function indicators, including activated coagulation time (ACT), prothrombin time (PT), thrombin time (TT), and fibrinogen(FIB)levels, were compared between the two groups before and after nursing care.
Results The results showed that the average body temperature of patients in the study group was significantly higher than that of the control group. In terms of coagulation function, the activated coagulation time, prothrombin time, and thrombin time of the study group were significantly prolonged after nursing care, while the fibrinogen level was markedly reduced. Compared with before nursing care, the improvements were significant and better than those of the control group(P<0.01).
Conclusion   Warming blanket rewarming is more effective than natural rewarming in raising the body temperature of pediatric patients with hypothermia and significantly improving their coagulation function.
