Jun 15, 2016
This podcast explores topics such as intraoperative hypothermia, temperature regulation, and heat transfer in the operating room. It also covers the causes, effects, and treatment of hypothermia, along with non-malignant hyperthermia syndromes. The importance of pre-warming, intraoperative warming, and the placement of warmers in preventing hypothermia is highlighted. Additionally, the podcast discusses interesting facts about temperature regulation, including lack of correlation between fever severity and likelihood of infection, and the origin of the normal body temperature of 37 degrees Celsius.

Episode notes
Dr. Heimlich Saves Choking Patient
- Dr. Heimlich saved a woman choking on steak at her nursing home by performing the Heimlich maneuver.
- He was 96 years old and happened to be sitting at her table when it happened.
Hypothermia Effects on Risks
- Intraoperative hypothermia increases infection risk, duration of neuromuscular blockade, and cardiac morbidity.
- It does not increase risk of DVT/PE, contrary to common misconception.
How Hypothermia Increases Infection Risk
- Hypothermia doubles to triples infection risk by reducing blood flow and immune cell delivery to wounds.
- It also lowers superoxide production which impairs infection fighting.
