Effect of warm intravenous and irrigating fluids on body temperature during transurethral resection of the prostate gland

Abstract

Background: Transurethral resection of the prostate gland with irrigation fluid at room temperature leads to perioperative hypothermia which could give rise to adverse cardiovascular events in the perioperative period. The use of isothermic irrigation fluid reduces but does not eliminate this risk. Routine use of warm intravenous fluids along with isothermic irrigation had not been documented. This study set out to investigate the effect of the use of warm intravenous fluid together with isothermic irrigation fluid on the body temperature in patients undergoing transurethral resection of the prostate gland.

The Effects of Irrigation Solution Temperature on Body Temperature in Transurethral Surgeries

“…It was in conformity with the literature. 18 Temperature drops in our study were higher than Okeke et al; we thought the difference was due to mean operation times, which were shorter in their study.…”

Limiting heat loss during surgery in small animals

“…Fluids at T°amb reduce evaporative losses but may cause direct cooling. Studies in people have established the benefits of warming IFs during arthroscopy (Kim and others 2009), thoracotomy (Kjaergaard and Bach 2006) laparoscopy (Moore and others 1997) and prostatectomy (Okeke 2007). Furthermore, the current NICE guidelines warn that IFs at T°amb significantly increase the risk of inadvertent perioperative hypothermia and propose that it is clinically negligent not to warm all IFs used intraoperatively to 38°C to 40°C (NICE 2008).…”

“…The reported effects of postoperative hypothermia on the pain experience of people are conflicting (Benson 2012), although ‘thermal comfort’, an important aspect of postoperative wellbeing, is consistently reduced by hypothermia (Okeke 2007). There is limited evidence that similar problems (eg, prolonged recoveries from anaesthesia) also occur in hypothermic small animals (Pottie and others 2007), although others, such as wound breakdown, do not (Beal and others 2000).…”

Implementing AORN Recommended Practices for Minimally Invasive Surgery: Part I

“…1(p164) Signs and symptoms of resultant hyponatremia may include bradycardia, hypertension followed by hypotension, nausea, vomiting, headache, visual disturbances, agitation, confusion, and lethargy. 30 However, during hysteroscopy, warmed fluids used as distention media may dilate the vasculature and lead to intravasation. The surgeon should suspect that a perforation has occurred if it becomes difficult to maintain distention.…”
