膀胱冲洗液加温对前列腺电切术患者心率变异性的影响

Influence of Bladder Irrigation Fluid warming on Heart Rate Variability in Patients with Tran-surethral Resection of Prostate

【目的】研究加温膀胱冲洗液对经尿道前列腺电切术患者心率变异性的影响。【方法】选取硬膜外麻醉下行经尿道前列腺电切术（TURP）患者60例，随机分为膀胱冲洗液加温组（试验组）和不加温组（对照组）。分别观察记录两组患者在麻醉前（T0）、麻醉后15 min（T1）、前列腺电切开始后5 min（T2）、前列腺电切后开始后10 min（T3）、前列腺电切开始后15 min（T4）、切除前列腺结束后5 min（T5）的6个时段患者的心率变异性（HRV）、低频功率（1ow frequency ，LF）、高频功率（high frequency ，HF）、LF／HF值。【结果】在两组内， HRV 值T0与T1、T2、T3、T4比较差异有统计学意义（ P ＜00．5）；LF／HF、LF、HF值 T0与 T2、T3、T4比较差异有统计学意义（ P ＜00．5）；在两组间，T2、T3、T4时间点LF／HF、LF、HF相比较差异有统计学意义（ P＜00．5）。【结论】膀胱冲洗液加温可减轻TURP患者术中的 HRV的影响，减少循环系统并发症。

Objective]To investigate the effect of the warm urinary bladder irrigation fluid on heart rate variability（HRV） in patients transurethral resection of prostate（YURP） .[Methods]Sixty cases of epidural an‐esthesia in patients undergoing TURP were selected and divided into two groups ：the experimental group （Ⅰgroup） as bladder irrigation fluid warming group and the control group （Ⅱ group） which was not warmed . Values of HRV ,low frequency power （LF） ,high frequency power （HF） ,LF /HF were observed and recor‐ded before anesthesia （T0 ） ,15min after anesthesia （T1 ） ,5min （T2 ） ,10min （T3 ） ,15min （T4 ） after TURP start and 5 minutes（T5 ） after excision[.Results]In the two groups ,the difference of HRV value was statisti‐cally significant at T0 ,T1 ,T2 ,T3 and T4 （ P 〈0 0.5） ,In the two groups ,the different HRV values were sta‐tistically significant at T0 ,T1 ,T2 ,T3 and T4 （ P 〈0 0.5）;Values of LF/HF ,LF ,HF at T0 T2 ,T3 and T4 were compared ,the difference was statistically significant （ P 〈0 0.5）;In the two groups ,LF/HF ,HF and LF at T3 ,T4 and T2 were compared ,the difference was statistically significant （ P 〈0 0.5）[.Conclusion]Blad‐der irrigation fluid warming can reduce the impact of HRV in patients with TURP and reduce the complica‐tions of the circulatory system .
