Factors associated with unintended perianesthesia hypothermia.

Background: Our hypothesis was that total intravenous anesthesia (TIVA) is associated with an increase in hypothermia.

Methods: Inclusion criteria were patients from the National Anesthesia Clinical Outcomes Registry undergoing a general anesthetic during 2019. Data collected included patient age, sex, American Society of Anesthesiologists physical status classification system score (ASAPS), duration of anesthetic, use of TIVA, type of procedure, and hypothermia.
