BACKGROUND AND OBJECTIVES Hypothermia is likely to develop faster during spinal anesthesia than epidural anesthesia. A natural consequence of the rapid temperature decrease during spinal anesthesia is that the shivering threshold will be reached sooner and that more shivering will be required to prevent further hypothermia. We tested the hypotheses that the onset of hypothermia is more rapid an...

one of the most common complications of operation and anesthesia is shivering. the purpose of this study was to compare the effectiveness of ondanseton and meperedine in preventing shivering after off-pump coronary artery bypass graft (opcab). in this double-blind randomized clinical trial, the sample consisted of 90 patients, who were candidates of cabg under general anesthesia. these patients...

The concurrent neural control of two thermoregulatory responses, shivering thermogenesis (ST) and nonshivering thermogenesis (NST), was investigated in chronically implanted cold-exposed rats. The effects of heating the preoptic/anterior hypothalamus (POAH) on shivering and on the rate of oxygen consumption (Vo2) were measured in these unanesthetized animals. With ambient temperature maintained...

INTRODUCTION Shivering is among the unpleasant and potentially harmful side effects of spinal anesthesia. The aim of this randomized double-blind clinical trial was to compare the antishivering effect of two different doses of intrathecal pethidine on the incidence and intensity of shivering and other side effects in patients who underwent cesarean section. METHODS In this study, 150 parturie...

Background:Postanesthetic shivering (PAS) isrelativelycommon side-effectof general anesthesia. We examined the preventive effects of ondansetron,ketamineor both on postanesthetic shivering. Patients and Methods:In this prospective, randomized, double-blindcontrolled trial, 120 ASA I-II, patients, undergoing ENTsurgery under general anesthesia were randomly assigned to one of four equal groups r...

The purpose of this study was to evaluate the effect of exercise on the subsequent postexercise thresholds for vasoconstriction and shivering. On two separate days, with six subjects (3 women), a whole body water-perfused suit slowly decreased mean skin temperature (approximately 7.0 degreesC/h) until thresholds for vasoconstriction and shivering were clearly established. Subjects were then rew...

Postanaesthetic shivering is a frequent complication following general anaesthesia. The aim of this study was to compare the effectiveness of three doses of nefopam with clonidine and placebo in the prevention of postanaesthetic shivering. We studied 371 patients undergoing abdominal or orthopaedic surgery. Patients were allocated to one of five groups: Group A (n = 73) received 0.2 mg x kg(-1)...

Background: Giving spinal anaesthesia is an effort to relieve pain create optimal conditions for surgery operation consciously. A shivering event frequently follows the phenomenon of long duration operation. 
 Purpose: The study aimed determine relationship between and in post patients.
 Methods: design a quantitative uses cross-sectional approach. Sampling used systematic sampling te...

BACKGROUND Thermoregulatory control is based on both skin and core temperatures. Skin temperature contributes approximately 20% to control of vasoconstriction and shivering in unanesthetized humans. However, this value has been used to arithmetically compensate for the cutaneous contribution to thermoregulatory control during anesthesia--although there was little basis for assuming that the rel...
