In cold-exposed adult humans, significant or lethal decreases in body temperature are delayed by reducing heat loss via peripheral vasoconstriction and by increasing rates of heat production via shivering thermogenesis. This brief review focuses on the mechanisms of fuel selection responsible for sustaining long-term shivering thermogenesis. It provides evidence to explain large discrepancies i...

BACKGROUND AND PURPOSE Hypothermia might prove to be therapeutically beneficial in stroke victims; however, even mild hypothermia provokes vigorous shivering. Meperidine and dexmedetomidine each linearly reduce the shivering threshold (triggering core temperature) with minimal sedation. We tested the hypothesis that meperidine and dexmedetomidine synergistically reduce the shivering threshold w...

BACKGROUND As the practice of aggressive temperature control has become more commonplace, new clinical problems are arising, of which shivering is the most common. Treatment for shivering while avoiding the negative consequences of many anti-shivering therapies is often difficult. We have developed a stepwise protocol that emphasizes use of the least sedating regimen to achieve adequate shiver ...

PURPOSE Some patients with pharmacoresistant epilepsy undergoing the Wada test experience transient shivering. The purpose of this study was to investigate various clinical and radiographic characteristics of these individuals to delineate underlying mechanisms of this phenomenon. METHODS A systematic review of prospectively collected information on patients undergoing the Wada test was perfo...

BACKGROUND AND PURPOSE Reducing body temperature can prolong tolerance to ischemic injury such as stroke or myocardial infarction, but is difficult and uncomfortable in awake patients because of shivering. We tested the efficacy and safety of the alpha-2-adrenergic agonist dexmedetomidine for suppressing shivering induced by a rapid infusion of cold intravenous fluids. METHODS Ten subjects re...

BACKGROUND Shivering is a frequent event during spinal anesthesia and meperidine is a well-known effective drug for prevention and treatment of shivering. Nefopam is a non-opiate analgesic and also known to have an anti-shivering effect. We compared nefopam with meperidine for efficacy of prevention of shivering during spinal anesthesia. METHODS Sixty five patients, American Society of Anesth...

BACKGROUND Surgery and anaesthesia cause shivering due to thermal dysregulation as a compensatory mechanism and is worsened by vasodilatation from spinal anaesthesia that redistributes core body heat. Due to paucity of data Mulago Hospital's post spinal shivering burden is unknown yet it causes discomfort and morbidity. METHODS Ethical approval was obtained to perform the study among consenti...

background the involved neurotransmitter pathways in the postoperative shivering (pos) are poorly understood. recently, 5-hydroxytryptamine 3 (5-ht3) receptor antagonists have been reported to prevent pos. we investigated the effect of ondansetron, a 5-ht3 antagonist that is used to treat postoperative nausea and vomiting, on shivering. objectives this study aimed to compare the efficacy of ond...

conclusions the results of this study showed that ketamine, doxapram and meperidine are equally effective in the prevention of postoperative shivering. background postanaesthetic shivering is one of the most common unpleasant complications in patients. objectives the aim of this study was to compare the efficacy of doxapram, ketamine and meperidine in prevention of shivering after anaesthesia. ...
