aim and background:   shivering is a common post anesthesia complication. intravenous methods and materials:   in a rct, 60 adult patients in asa class 1 & 2 scheduled for   c . at the end of the anesthesia, the patients’ shivering was evaluated in the findings:   there was no difference at decrease of spo2 & h.r. & map between 2 groups. there conclusions:   0.2 mg clonidine tablet, 2 hours bef...

UNLABELLED In a previous study we have shown that the antihypertensive drug, urapidil, stops postanesthetic shivering. One possible mechanism in the inhibition of postanesthetic shivering by urapidil may be alterations in thermoregulatory thresholds. We therefore studied the effects of urapidil on vasoconstriction and shivering thresholds during cold-induced shivering in volunteers. Seven healt...

background: post? and intra?operative  shivering is one of the most complications of spinal anesthesia so recommend a suitable drug with at least complications for prevention and control of postoperative shivering. this current study aimed to compare the preventive effect of  hydrocortisone on intra? and post?operative shivering in patients undergoing surgery with spinal anesthesia. materials a...

Effective hypothermia in critical care requires a strategy to prevent and manage shivering. Core body temperature in mammals is highly regulated [1]. Hypothermia leads to the activation of measures to counteract this, reducing heat loss through vasoconstriction and increasing heat generation through increased metabolism and shivering. Shivering resists the reduction in core temperature but also...

The pigeon's main source of regulated heat production, shivering, is especially likely to be used for thermoregulation during the dark phase of the day when there is little heat from locomotor activity. However, food stored in the pigeon's crop is digested during the night, and digestion-related thermogenesis (DRT) will provide heat that should decrease the need for shivering to maintain body t...

Inadvertent postoperative hypothermia is common among patients in the postanesthesia care unit (PACU). Shivering traditionally is attributed to hypothermia, but it is not always thermoregulatory. The exact impact of hypothermia and shivering on standard PACU monitoring parameters of patients has not been sufficiently studied. The present study included 170 orthopedic surgical patients. On PACU ...

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...

We tested the hypothesis that cooling the extradural space may provoke shivering, by giving three 80-ml extradural injections of warm (39.8 +/- 1.2 degrees C) or cold (17 +/- 2.2 degrees C) saline to four healthy volunteers, whilst recording central temperature and electromyographic activity from four muscles. The first injection (always cold) did not induce shivering in any of the subjects. Th...
