Thermoregulation and mild peri-operative hypothermia
Induced hypothermia (28–32°C) has been indicated for some time for myocardial and cerebral protection in cardiac anaesthesia. However, it has recently been recognised that mild, inadvertent peri-operative hypothermia is associated with a number of adverse postoperative outcomes. Patient outcome can be improved by preventing peri-operative hypothermia. Although there is no clear definition of mi...
متن کاملPerioperative thermoregulation and heat balance.
Core body temperature is normally tightly regulated to within a few tenths of a degree. The major thermoregulatory defences in humans are sweating, arteriovenous shunt vasoconstriction, and shivering. The core temperature triggering each response defines its activation threshold. General anaesthetics greatly impair thermoregulation, synchronously reducing the thresholds for vasoconstriction and...
متن کاملTemperature monitoring and perioperative thermoregulation.
Most clinically available thermometers accurately report the temperature of whatever tissue is being measured. The difficulty is that no reliably core-temperature-measuring sites are completely noninvasive and easy to use-especially in patients not undergoing general anesthesia. Nonetheless, temperature can be reliably measured in most patients. Body temperature should be measured in patients u...
متن کاملPerioperative complications of hypothermia.
Perioperative hypothermia is a common and serious complication of anesthesia and surgery and is associated with many adverse perioperative outcomes. It prolongs the duration of action of inhaled and intravenous anesthetics as well as the duration of action of neuromuscular drugs. Mild core hypothermia increases thermal discomfort, and is associated with delayed post anaesthetic recovery. Mild h...
متن کاملThe effects of mild perioperative hypothermia on blood loss and transfusion requirement.
BACKGROUND Anesthetic-induced hypothermia is known to reduce platelet function and impair enzymes of the coagulation cascade. The objective of this meta-analysis and systematic review was to evaluate the hypothesis that mild perioperative hypothermia increases surgical blood loss and transfusion requirement. METHODS The authors conducted a systematic search of published randomized trials that...
