灌洗液温度对经皮肾镜取石患者生命体征影响的研究

The impact of temperature of irrigating fluid on life signs of patients undergoing percutaneous nephrolithotomy

目的观察不同温度的灌洗液对微创经皮肾镜取石术(mPCN)老年患者生命体征的影响。方法将90例行mPCN老年患者随机分为A、B、C三组,每组30例,分别采用不同温度的灌洗液,A组灌洗液温度为(20～24)℃,B组为(28～30)℃,C组为(36～37)℃,观察采用不同温度的灌洗液进行手术时患者的体温(T)、平均动脉压(MAP)、心率(HR)的变化及寒战发生率。结果 C组的T、MAP、HR在mPCN前后无明显改变(P>0.05);C组寒战发生率低于A组和B组(P<0.01)。结论 mPCN中采用(36～37)℃的灌洗液可使患者体温、血压、心率的变化不明显,同时降低寒战发生率。

Objective To investigate the temperature of irrigating fluid on life signs of elderly patients un- dergoing the minimally invasive percutaneous nephrolithotomy lithotomy （mPCN）. Methods Ninety elderly patients undergoing mPCN were randomly divided into three groups by different temperature of fluid, each group 30 cases. The temperature of irrigating fluid group A were （20 - 24） ℃, group B （28 - 30） ℃, group C （ 36 - 37 ）℃. Body tem- perature （T）, mean arterial pressure （MAP）, heart rate （HR） and the incidence of shivering were observed when using different temperature fluid on patients. Results In group C,T, MAP and HR showed no significance between before and after mPCN （P 〉0. 05） ; the incidence of shivering in group C was lower than in group A or group B （P 〈 0. 01 ）. Conclusion Using irrigating fluid ranging from 36 to 37 degree℃ in mPCN can reduce the changes of body temperature, blood pressure, heart rate and the incidence of shivering.
