Background: Shivering in the post anesthesia care unit is a common and distressing complication for patients after receiving general or regional anesthesia. Perioperative hypothermia has been associated with an increase morbidity mortality. Both central peripheral thermoregulation impaired by Thermoregulatory system synchronizes defense to maintain body’s heat coolness within narrow range, thus...

Intraoperative dexmedetomidine infusion may be effective in the prevention of post general anesthetic shivering. However, there is no study has been performed under epidural anesthesia. We aimed to investigate the effect of intraoperative usage of dexmedetomidine infusion on post epidural anesthesia shivering. Sixty patients were randomly assigned to two groups. Group DEX was received dexmedeto...

OBJECTIVES This study aimed to evaluate the relative efficacy of prophylactic intravenous (IV) clonidine and tramadol for control of intraoperative shivering following spinal anesthesia. MATERIALS AND METHODS After institutional ethical clearance, 142 patients were chosen from either gender, aged 20-60 years, physical status American Society of Anesthesiology Class I and II scheduled for elec...

BACKGROUND AND OBJECTIVES Patients undergoing laparoscopy often complain of shoulder pain, shivering, or both following laparoscopy. An increase in awake microlaparoscopic procedures has been reported. The objective of this study was to investigate the usefulness of heating and humidifying the carbon dioxide gas for the pneumoperitoneum with the Insuflow device (Lexion Medical, St. Paul, Minnes...

All general anesthetics markedly impair thermoregulatory responses; nonetheless, sufficient hyperthermia or hypothermia will trigger most protective reflexes. Shivering, however, remains an exception among thermo-regulatory responses: it is common during postanesthetic recovery, but is rare at typical anesthetic concentrations. This observation suggests that general anesthesia impairs shivering...

This review examines the heat production component of thermoregulation in adult humans. It describes the energy requirements of shivering muscles as they attempt to provide sufficient heat to counterbalance increases in heat loss in cold environments. Emphasis is placed on types of metabolic substrates used under various shivering conditions as well as on the effects energy deficit and food con...

Participants in prolonged, physically demanding cold-weather activities are at risk for a condition called "thermoregulatory fatigue". During cold exposure, the increased gradient favoring body heat loss to the environment is opposed by physiological responses and clothing and behavioral strategies that conserve body heat stores to defend body temperature. The primary human physiological respon...
