Summary
Patient hypothermia during anesthesia is a serious risk, not just an inconvenience. Early prevention and effective warming are crucial for patient safety and reducing healthcare costs.
Area of Science:
- Anesthesiology
- Perioperative Medicine
- Patient Safety
Background:
- Hypothermia is a common complication during anesthesia and surgery.
- Historically, it was considered an unavoidable inconvenience.
- Emerging evidence highlights significant morbidity associated with hypothermia.
Purpose of the Study:
- To underscore that hypothermia is preventable and associated with significant morbidity.
- To emphasize the importance of initiating preventive measures early, including in the preoperative holding area.
- To promote the understanding and utilization of effective warming methods.
Main Methods:
- Review of existing literature on perioperative hypothermia.
- Analysis of the physiological mechanisms of core temperature decline during anesthesia and surgery.
- Evaluation of current warming strategies and their underutilization.
Main Results:
- Hypothermia begins before surgery and is linked to increased intraoperative and postoperative morbidity.
- Effective warming methods are available but underused in clinical practice.
- Understanding temperature regulation is key to prevention.
Conclusions:
- Hypothermia is a preventable complication with serious patient outcomes.
- Early and consistent application of warming interventions is essential.
- Improved knowledge and practice among perioperative teams can enhance patient safety and reduce institutional costs.
