Severe hypothermia and an ascending impairment of shivering are previously undescribed clinical signs in hyperacute experimental allergic encephalomyelitis (EAE) in the Lewis rat. These occurred in hyperacute EAE induced by inoculation with guinea pig spinal cord homogenate and heat-killed Bordetella pertussis. Hypothermia was first detected on day 6-7 post-inoculation, within 12-24 h of the on...
Objective We evaluated the efficacy of 5-HT3 receptor antagonists for the prevention of postoperative shivering. Methods We searched PubMed, the Cochrane Library, EMBASE and Web of Knowledge to find randomized controlled trials (RCT) of 5-HT3 receptor antagonists for the prevention of postoperative shivering. Two researchers independently screened studies, extracted data, and assessed quality i...
conclusions administration of two different doses of intravenous ondansetron, 6 mg and 12 mg, significantly attenuates spinal induced hypotension, bradycardia and shivering compared to the control saline group. however, the hemodynamic profiles and shivering in experimental groups were not statistically different. results demographic data were not statistically different among groups. hr was st...
Abstract Shivering after surgery is common and followed by many problems. Therefore prevention of shivering is important specially in elderly and Ischemic Heart Disease patients. The etiology of shivering is unknown, although is thought intraoperative hypothermia is a major causative factor. Another possible etiology is fever and chills secondary to activation of the inflammatory responses and...
OBJECTIVES The aim of this randomized double-blind study was to investigate whether 20 microg of intrathecally administered fentanyl would influence the incidence and severity of shivering in patients undergoing cesarean section. MATERIAL AND METHOD Sixty healthy patients scheduled for cesarean section under spinal anesthesia using 2.2 ml of 0.5% hyperbaric bupivacaine with 0.2 ml of morphine...
Background:Postoperative shivering is one of the most common problems after general and local anesthesia. We compared the efficacy of low dose ketamine versus pethidine in controlling shivering after surgery.Methods : In a double-blind randomized Clinical trial, 132 ASA I,II patients candidate for tonsillectomy were randomized to receive either pethidine and ketamine. At the time of arrival to...
The special antishivering action of meperidine may be mediated by its kappa or anticholinergic actions. We therefore tested the hypotheses that nalbuphine or atropine decreases the shivering threshold more than the vasoconstriction threshold. Eight volunteers were each evaluated on four separate study days: 1) control (no drug), 2) small-dose nalbuphine (0.2 microg/mL), 3) large-dose nalbuphine...
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...
Received: 9 Apr , 2013 Accepted: 9 Jun , 2013 Abstract Background & Aims: Post-operative shivering is very common and it is usually followed by many problems such as an increase in oxygen consumption, blood pressure, intracranial and intraocular pressure, and post-operation pain. Therefore, it is very important to prevent shivering especially in the elderly and ischemic heart disease pa...
Introduction and Purpouse: Postoperative shivering, which is unpleasant and annoying to the patient, occurs in patients with general anesthesia occurring in up to 65% of cases. Different mechanisms have been proposed for postoperative shivering. Chills after anesthesia can cause cardiovascular complications, bleeding and infections. this study, effects of dexamethasone, pethidine and ketamine h...
