冲洗液加温对经皮肾镜碎石取石术患者体温的影响

The effects of heated irrigation fluid on body temperature of percutaneous nephrolithotomy patients

目的探讨冲洗液加温对经皮肾镜碎石取石术(PCNL)患者术中及手术结束时体温的影响。方法将100例接受PCNL的患者随机分为A、B两组,每组50例。A组应用室温的生理盐水进行冲洗,B组应用加温至37℃的生理盐水进行冲洗,比较两组的一般参数、体温变化以及组内的体温变化。结果两组的年龄、体重、手术时间、冲洗液量、输液量及手术开始时体温无显著性差异。两组手术结束时体温均显著下降(P<0.01),A组的术中平均体温明显低于手术开始时体温(P<0.01),B组术中平均体温低于术前体温,但无统计学意义。B组手术结束时体温及术中平均体温明显高于A组(P<0.01),体温下降幅度明显小于A组(P<0.01)。结论在经皮肾镜碎石取石术中冲洗液加温可以有效防止患者术中及手术结束时低体温。

Objective To explore the effects of heated irrigation fluid on body temperature of percutaneous nephrolithotomy （PCNL） patients. Methods 100 patients with PCNL were randomly divided into two groups ： group A （ n = 50 ） and group B （ n = 50 ）. Patients in group A accepted room-temperature physiological saline to irrigate during PCNL while those of group B accepted 37~C physiological saline. The changes of temperature and general data were compared between the two groups and the changes of body temperature were also compared within each group. Results There were no significant difference in age, weight, operation duration, irrigation fluid, amount of transfusion fluid and preoperative temperature between the two groups. Postoperative temperature of the two groups were obviously lower than preoperative temperature （ P 〈 0.01 ）. The average temperature during operation in group A was significantly lower than preoperative temperature （P 〈0.01 ）,but there was no statistical significance in group B. The postoperative temperature and average temperature of group B were higher than those of group A during operation （ P 〈 0.01 ）. The range of the body temperature decrease in group B was significantly lower than that in group A （ P 〈 0. 01 ）. Conclusion The heated irrigation fluid can effectively prevent hypothermia during and after PCNL.
