Learn About Critical Care Temperature Monitoring Sites

The Importance of Monitoring Patient Temperature

The human body requires a nearly constant internal temperature to maintain healthy metabolic function. Under normal circumstances, the thermoregulatory system maintains core temperature within 0.2˚C of 37˚C, or normothermia. General anesthetics inhibit thermoregulation causing significant deviations from normal body temperature.

As a result, all patients under anesthesia, regardless of age, weight or other factors, are at increased risk of hypothermia and/or hyperthermia. Precise temperature monitoring is critical to preventing the serious complications associated with these conditions.

Potential Risks – the Importance of Maintaining Normothermia

Perioperative hypothermia, defined by a core body temperature below 36˚C, can occur rapidly in anesthetized patients. The reason for this is, in addition to inhibiting the body’s ability to generate and retain heat, general anesthetics cause vasodilation – widening of the blood vessels. This allows warmer blood to flow from the core to the periphery, resulting in significant heat loss to the core.

As a result of this redistribution of heat, the patient’s core temperature drops between 1˚ to 1.5˚C within the first hour following induction of anesthesia. The numerous adverse effects of hypothermia are well documented and include impaired blood coagulation, increased risk of surgical site infection, potential morbid myocardial events, and delayed wound healing resulting in longer hospital stays.

Preventing Perioperative Hypothermia

Hypothermia can be prevented by vigilant patient temperature monitoring and use of an active patient warming system. The Surgical Care Improvement Project (SCIP) mandates that all patients under anesthesia for one hour or longer must be actively warmed to maintain normothermia (Learn more about NOVAMED USA’s KOALA reusable underbody warming system and the SCIP Initiative).

Effects of Malignant Hyperthermia

Malignant hyperthermia is an inherited condition often triggered by an allergic reaction to certain anesthetics. Defined by a sudden rapid increase in patient temperature, this condition impairs the body’s ability to thermoregulate, supply oxygen and remove carbon dioxide, leading to circulatory collapse and death if not treated quickly.

Precise temperature monitoring is critical to the detection and early treatment of hyperthermia. If surgeons notice a sudden increase in patient temperature, they can respond with treatment before irreversible damage occurs.
