The incidence and influencing factors of hypothermia in patients after transurethral prostatectomy: a systematic review and meta-analysis.

INTRODUCTION

Inadvertent perioperative hypothermia prevalence and its risk factors in Transurethral resection of the prostate(TURP) vary partly due to definition criteria.

OBJECTIVE

This systematic review aimed to identify the prevalence and risk factors of Inadvertent perioperative hypothermia in TURP patients.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES: PubMed, the Cochrane Library, MEDLINE, Embase, Web of Science, China Knowledge Resource Integrated Database, Wanfang Database, Chinese Biomedical Database, and Weipu Database were searched through December 31st, 2024.

ELIGIBILITY CRITERIA: Literature published in English or Chinese reporting factors influencing IPH in TURP patients was eligible for inclusion.

DATA EXTRACTION AND SYNTHESIS: Data Extraction and Synthesis Two investigators independently extracted data and assessed study quality. Continuous variables were analysed using 95% CI. Categorical variables were analysed using OR and 95% CI.

RESULTS

TURP patients with Inadvertent perioperative hypothermia were compared to those without Inadvertent perioperative hypothermia for haemorrhage, age, temperature of the rinsing solution and operation time. The current meta-analysis included 10 studies, with a total of 2,668 patients.The overall Inadvertent perioperative hypothermia prevalence was 29%. The meta-analysis and systematic review showed that haemorrhage (OR: 2.05 [1.97-2.13], P < 0.00001) and age (OR: 1.05 [1.02-1.08], P = 0.0002) were Inadvertent perioperative hypothermia risk factors for Inadvertent perioperative hypothermia in TURP patients. In contrast, no significant relationship was observed between Inadvertent perioperative hypothermia and temperature of the rinsing solution and operation time. The researchers should do early and regular screening, the whole process of managing high-risk groups, and formulating targeted measures according to risk factors for precise prevention.

CONCLUSIONS

This meta-analysis indicated that haemorrhage and age might be associated with a greater risk of IPH in TURP patients. Associations between Inadvertent perioperative hypothermia and temperature of the rinsing solution and operation time require further investigation.
