BACKGROUND One of the unpleasant side effects of general anesthesia is shivering in the process of recovery. It is an involuntary oscillatory mechanical movement that can be classified as clonic movements. These movements can affect one or several groups of skeletal muscles beginning from 5 to 30 minutes after the discontinuation of anesthesia. OBJECTIVES We aimed to study ketamine's effect o...

Postoperative administration of clonidine is an effective treatment for shivering. However, the ability of this drug to stop postanesthetic shivering when administered intraoperatively remains controversial. Furthermore, the relative efficacy of clonidine during isoflurane and propofol anesthesia remains unknown. We therefore evaluated the incidence of postanesthetic shivering in patients given...

PURPOSE The aim of this study was to evaluate the effect of dexmedetomidine on shivering during spinal anesthesia. METHODS Sixty patients (American Society of Anesthesiologists physical status I or II, aged 18-50 years), scheduled for elective minor surgical operations under spinal anesthesia with hyperbaric bupivacaine, were enrolled. They were administered saline (group C, n = 30) or dexmed...

a bstract background: shivering is a common complication of general and epidural anesthesia. warming methods and many drugs are used for control of shivering in the recovery room. the present study is a randomized clinical trial aimed to investigate the effects of two interventions in comparison with pethidine which is the routine treatment on shivering in patients undergoing abdominal surgery ...

The mammalian response to hypothermia is increased metabolic heat production, usually by way of muscular activity, such as shivering. Seals, however, have been reported to respond to diving with hypothermia, which in other mammals under other circumstances would have elicited vigorous shivering. In the diving situation, shivering could be counterproductive, because it obviously would increase o...

background: shivering is one of the common problems in spinal anesthesia. the objective of the present study was to evaluate the effect of intrathecal fentanyl (25 μg) on incidence and severity of intraoperative and postoperative shivering. methods: a double-blind randomized controlled study was conducted in eighty healthy women (asa physical status i) scheduled for elective cesarean section un...

BACKGROUND The analgesic nefopam does not compromise ventilation, is minimally sedating, and is effective as a treatment for postoperative shivering. The authors evaluated the effects of nefopam on the major thermoregulatory responses in humans: sweating, vasoconstriction, and shivering. METHODS Nine volunteers were studied on three randomly assigned days: (1) control (saline), (2) nefopam at...

background: postoperative shivering is an important and troublesome condition during recovery from general anesthesia.  corticosteroids have been recommended to facilitate recovery and diminish shivering after cardiac surgery.  previous studies recommended 0.6 mg/kg dexamethasone for reducing postoperative shivering in patients undergoing cardiac surgery.    objective: to test this assertion, w...
