Influence of Postoperative Bladder Washout on the Heart Rate: Cohort Study

Abstract

Background: Endoscopic urological surgery is a marginal invasive tool. However, sympathetic activity could be created during the postoperative sequences due to a bladder washout by means of a dynamic bladder filling.

Methods: We studied (cohort study) the preoperative and postoperative response of a patients heart rate during the dynamic bladder washout using Holters monitor.

Results: A total of 15 consecutive male patients aged from 65 to 96 years were included. There was a significant difference in the average heart rate (with P = 0.0053) (69.61 8.83) before and (73.58 11.14) during the process. There was no significant difference in the average low frequency (LF) (P = 0.217706) (349.30 446.08) before and (304.54 356.53) during the washout. There was no significant difference in the average high frequency (HF) (parasympathetic activity) (P = 0.116) (323.77 471.92) before and (273.69 413.19) during the washout. The average before the LF/HF washout is 2.97 3.50 and the average during the LF/HF washout is 3.91 4.16. It showed limited significance (P = 0.054).

Discussion: The only significant result is that the bladder washout increases the heart rate by boosting the orthosympathetic activity. It is being studied that the sensation of the bladder filling is transmitted via the sympathetic hypogastric nerve (orthosympathetic activity). Nevertheless, it might be necessary to take a larger population sample with more homogeneous inclusion criteria.

Conclusion: We conclude that the postoperative bladder washout after transurethral resection of the prostate and bladder cancer significantly increases the heart rate.
