Both forced air warming and fluid warming play a crucial part in preventing hypothermia and its documented complications in patients.

NICE (UK), SIAARTI (Italian) , SCIP (US) guidelines recommend using forced air warming to prevent perioperative hypothermia and that

fluids used during an operation should be warmed to normal body temperature. Please see Nice guidelines in clinical information

Hypothermia, defined by NICE as a core temperature below 36°C2 is common among surgical patients due to a range of factors. Cold temperatures in operating rooms, open cavities and often administration of cold IV fluids3  these factors combined with the fact that general anesthetics can impair normal thermoregulatory control to some extent4. Can account for the high incidence of hypothermia particularly among certain groups of patients.

An analysis conducted into the costs associated with hypothermia concluded that the cost of preventing intra-operative hypothermia is much less than the cost of treating the adverse outcomes associated with it 5. A further study found  treating the increased risk of surgical site infections can cost the NHS around £10,000 to treat.
