摘要
目的 探讨经尿道手术中不同温度冲洗液对心血管系统的影响。 方法 87例经尿道电切手术患者随机分为两组 ,分别应用低温和等温冲洗液 ,监测冲洗液温度对中心体温、生命体征和心功能的影响。 结果 低温冲洗液组 48例术中体温平均下降 2 .1℃ ,平均动脉压升高 ,心排出量下降 ,系统血管阻力增加 ;等温冲洗液组 39例术中体温下降 0 .3℃ ,心功能稳定 ,生命体征平稳。 结论 低温冲洗液可导致体温下降 ,降低心排出量和显著增加系统血管阻力 ,增加老年患者心血管并发症的危险性 ,而等温冲洗液则可有效维持心功能的稳定 ,提高经尿道手术的安全性。
Objective To evaluate the effects of temperature of the irrigation fluid on body temperature and cardiovascular performance during transurethral surgery. Methods 87 cases were randomly divided into two groups according to the temperature of irrigation fluid used: the ambient (21～ 24 ℃) and the isothermic (35～36 ℃). Body temperature, blood glucose, ECG, HR, SaO 2, cardiac output (CO), mean arterial pressure (MAP) and systemic vascular resistance (SVR) were monitored during the transurethral surgery. Results Body temperature was decreased 2.1 ℃, MAP elevated, CO decreased and SVR increased in the ambient group, while body temperature was decreased only 0.3 ℃ and cardiac performance was maintained relatively stable in the isothermic group. Conclusions Hypothermia, resulted from the use of large amount of low temperature irrigation fluid during transurethral surgery has detrimental effects on body temperature and cardiovascular performance. Isothermic irrigation fluid would stablize the cardiovascular performance and so increases the safety of transurethral surgery.
