How do you prevent postoperative hypothermia and blood loss?
Postoperative hypothermia leads to a number of problems that include shivering and increases in myocardial oxygen utilization; increases in wound infection; slowing of drug metabolism; and lastly, effects on coagulation function. Studies have shown that hypothermia leads to significant increases in blood loss thus emphasizing the importance of maintaining normothermia.
