加温输液对骨科手术患者中心体温和寒颤的影响研究

Effect of heated infusion on the core temperature and shivering of patients receiving orthopedic surgery

目的探讨加温输液对骨科手术患者术中中心体温和寒颤的影响。方法将59例骨科手术患者分为干预组和对照组。干预组应用便携式输液加温器对液体进行加温输液,对照组常温输液,监测患者麻醉前和麻醉后30 min、60 min、90 min的肛温及术中、术毕时寒颤发生情况,询问患者术毕时自觉发冷情况。结果随着手术的进行,两组患者肛温均呈下降趋势(P<0.05),但组间比较差异无统计学意义(P>0.05);加温输液组患者寒颤发生率和自觉发冷率低于对照组(P<0.05)。结论加温输液可以有效降低骨科手术患者术中寒颤发生率,提高患者的舒适度。

Objective To explore the effects of heated infusion on the core temperature and shivering of patients receiving orthopedic surgery. Methods A total of 59 cases of patients were divided into two groups randomly. The portable infusion warmer was used to heat the fluid in the intervention group while all fluids were infused at room temperature in the control group. The rectal temperature of the two groups was compared before the general anesthesia, 30min, 60min and 90min after the anesthesia. And the incidence of shivering between the two groups was compared during the surgery and at the end of the surgery. The patients were asked whether they felt cold at the end of the surgery. Results As the operation ongoing, the rectal temperature of the two groups both decreased gradually （P 〈 0.05） , but the diferenccs between the two groups were not statistically significant （P 〉 0.05 ）. The incidence of shivering and cold - feeling in the intervention group were lower than those of the control group, and the differences were statistically significant （ P 〈 0.05 ）. Conclusion The heated infusion can effectively reduce the incidence of shivering and improve patients＇comfort.
