The Association Between Intraoperative Hypothermia and Adverse Postoperative Events in General Surgery.

Abstract

Introduction : Intraoperative hypothermia, a core temperature below 36∘C, is a frequent complication in general surgery. This review investigates the link between intraoperative hypothermia and the development of postoperative complications.

Literature Review : Maintaining normothermia is essential for positive surgical outcomes, as research confirms that even mild hypothermia heightens the risk of adverse events. Key complications include increased surgical site infections from impaired immunity and vasoconstriction, delayed anesthetic recovery, and coagulopathy causing higher blood loss and transfusion needs. Hypothermia also worsens cardiac risks like ischemia and arrhythmias, particularly in vulnerable patients. The resulting shivering increases metabolic stress and patient distress.

Conclusion : Intraoperative hypothermia is a modifiable risk factor for numerous preventable postoperative complications. Proactive warming strategies are crucial for patient safety and recovery. Therefore, continuous temperature monitoring and active warming should be a standard of care to mitigate risks and enhance surgical outcomes.
