Elderly patients and those with low body mass undergoing head and neck surgery face higher risks of intraoperative hypothermia. Active warming is recommended to prevent complications.

Area of Science:

  • Anesthesiology
  • Surgical Patient Safety

Background:

  • Intraoperative hypothermia is a significant risk in head and neck surgery.
  • Maintaining normothermia is crucial for patient outcomes.

Purpose of the Study:

  • To identify predictors of intraoperative hypothermia in head and neck surgery patients.
  • To determine the incidence of hypothermia and its complications.

Main Methods:

  • Retrospective analysis of patients undergoing head and neck surgery.
  • Comparison between actively warmed (forced-air) and unwarmed groups.
  • Assessment of clinical variables including age, body mass, and procedure duration.

Main Results:

  • Advanced age and decreased body mass were significant risk factors for hypothermia in unwarmed patients.

  • Unwarmed patients experienced lower mean core body temperatures (0.4°C lower).
  • Severe hypothermia occurred in 11.6% of unwarmed vs. 8.0% of warmed patients, with complications like delayed extubation and flap dehiscence.

    • Conclusions:

    • Head and neck surgery patients are susceptible to intraoperative hypothermia.
    • Elderly patients and those with low body mass require vigilant temperature monitoring.
    • Active forced-air warming is recommended for at-risk patients to mitigate complications.
