目的:观察不同温度冲洗液对经皮肾镜碎石取石术病人的体温、心率、血压等生命体征的影响,为同类手术选择冲洗液温度提供参考。方法:将60例肾结石行经皮肾镜碎石取石术患者随机分为室温组30例,采用23±1℃的室温冲洗液;加温组30例采用37±1℃的加温冲洗液。观察术中不同冲洗液对患者的体温、心率、血压的变化。结果:室温组术后体温为34.5±0.3℃,寒颤率为30%;加温组体温为36.1±0.3℃,寒颤率为2.67%。加温组的血压升高和心率加速等改变明显低于室温组,经统计学分析两组之间差异有显著意义。结论:经皮肾镜碎石取石术采用加温冲洗液可有效减少患者术后低体温、寒颤,使患者生命体征更加平稳。 OBJECTIVE: To observe the effects of different temperature rinsing fluids on vital signs such as body temperature, heart rate and blood pressure in patients undergoing percutaneous nephrolithotripsy, and to provide a reference for choosing the rinse temperature in the same kind of operation. Methods: Sixty patients with renal calculi underwent percutaneous nephrolithotomy were randomly divided into room temperature group (n = 30) and room temperature rinsing liquid (23 ± 1 ℃). The warming group was treated with 37 ± 1 ℃ warming rinse solution. To observe the intraoperative different irrigation fluid on the patient’s body temperature, heart rate, blood pressure changes. Results: The postoperative body temperature in room temperature group was 34.5 ± 0.3 ℃ and the rate of chills was 30%. The body temperature of warm group was 36.1 ± 0.3 ℃ and the rate of chills was 2.67%. In the warming group, the changes of blood pressure and heart rate were significantly lower than those in the room temperature group. The difference between the two groups was statistically significant. Conclusion: Percutaneous nephrolithotripsy with warm washing solution can effectively reduce postoperative hypothermia and shivering, and make patients’ vital signs more stable.
