Abstract
Introduction
Post-operative hypothermia is an adverse effect of anesthesia due to widespread inhibition of thermoregulatory processes, which can be mitigated through intraoperative warming. While forced warm-air systems are commonly used, they can pose challenges during procedures. Our study compared an enclosed water-sleeve warming system with a standard forced-air warming system, to compare their efficacy in maintaining normothermia during intrabdominal surgery.
Methods
In this controlled trial, 67 patients that underwent elective intrabdominal surgery were assigned to either the water-sleeve warming system (N = 30) or the forced-air warming system (N = 37). Patients gave written consent to the assignment of the warming method (IRB#1814, USF). The water-sleeve system utilized a plastic sleeve circulating warm sterile water at 40 °C on the patient's upper arm, with mild suction (-7 cm H2O) applied to promote venous dilation. The forced-air system used a disposable perforated blanket over the patient's upper body. Operating room temperatures were maintained at 20 °C. Temperatures were recorded preoperatively (sublingual), intraoperatively every 15 min (esophageal), and postoperatively upon arrival in PACU (sublingual).
Results
The water-sleeve group maintained a slightly higher median temperature intraoperatively compared to the control group, although the differences were not statistically significant. A Fisher test revealed that the water-sleeve group had fewer patients experiencing at least one intraoperative interval below 36 °C. Both warming methods successfully maintained normothermia upon arrival to the post-anesthesia care unit (PACU).
Conclusions
This study demonstrated that the water-sleeve warming system and the forced-air warming system were comparably effective in maintaining normothermia during intrabdominal surgery. No significant differences were observed in intraoperative or postoperative temperatures between the two groups. Given the similar efficacy and utility of the water-sleeve and forced-air warming systems, further research is needed to evaluate the cost-effectiveness of the water-sleeve warming system and to identify clinical scenarios where it may be preferable.
期刊介绍:
The objective of this new online journal is to serve as a multidisciplinary, peer-reviewed source of information related to the administrative, economic, operational, safety, and quality aspects of the ambulatory and in-patient operating room and interventional procedural processes. The journal will provide high-quality information and research findings on operational and system-based approaches to ensure safe, coordinated, and high-value periprocedural care. With the current focus on value in health care it is essential that there is a venue for researchers to publish articles on quality improvement process initiatives, process flow modeling, information management, efficient design, cost improvement, use of novel technologies, and management.
