Effects of the temperature of irrigation fluid on body temperature and cardiovascular performance during transurethral surgery / 中华泌尿外科杂志

ABSTRACT

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.
