Summary
Transurethral prostatic resection can cause significant body cooling due to irrigating fluid absorption. This heat loss occurs even with prewarmed fluids, impacting patient temperature during surgery.
Area of Science:
- Urology
- Surgical Physiology
- Patient Safety
Background:
- Transurethral prostatic resection (TURP) involves significant fluid absorption.
- Maintaining normothermia is crucial for patient outcomes during surgical procedures.
Purpose of the Study:
- To investigate the relationship between irrigating fluid absorption and body temperature changes during TURP.
- To identify factors contributing to heat loss in patients undergoing TURP.
Main Methods:
- Studied 30 patients undergoing TURP over 10-minute periods.
- Measured rectal and esophageal temperatures and fluid absorption.
- Utilized glycine with or without ethanol as irrigating fluid.
Main Results:
- Significant rectal temperature drop observed in patients with high fluid absorption (average 1328 ml).
- Esophageal and rectal temperature changes were closely correlated.
- Hypothermia occurred despite prewarming irrigating fluid to 37°C.
Conclusions:
- Irrigating fluid absorption is a significant mechanism for heat loss during TURP.
- Patient cooling during TURP is influenced by the volume of absorbed irrigating fluid.
- Further strategies are needed to mitigate heat loss during transurethral operations.
