This study aimed to assess the prophylactic efficacy of Tramadol and Dexamethasone in preventing shivering following spinal anesthesia. A total 162 patients aged 18 60, with ASA physical status I or II, undergoing various surgical procedures, were randomly assigned receive intravenous normal saline (Group C), tramadol at a dose 1 mg/kg T), dexamethasone 0.1 D). The occurrence shivering, its imp...

BACKGROUND AND OBJECTIVES Most studies in the literature correlating epidural opioids to postoperative shivering were carried out with obstetric patients whose thermoregulation center response might be different from non-pregnant patients. Our study aimed at comparing intra and postoperative shivering and other complications of epidural block with and without fentanyl in patients submitted to v...

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 o...

BACKGROUND Shivering is a frequent event during the perioperative period. We performed a prospective, randomized, double-blind study to determine whether intrathecal meperidine (0.2 mg/kg) decreases the incidence and intensity of shivering after spinal anesthesia for transurethral operations. METHODS Fifty patients scheduled for elective transurethral resection operations under spinal anesthe...

OBJECTIVES This study aimed to evaluate the relative efficacy of prophylactic intravenous (IV) clonidine and tramadol for control of intraoperative shivering following spinal anesthesia. MATERIALS AND METHODS After institutional ethical clearance, 142 patients were chosen from either gender, aged 20-60 years, physical status American Society of Anesthesiology Class I and II scheduled for elec...

BACKGROUND Side effects of spinal anesthesia are hypotension, bradycardia and shivering. Five-hydroxytriptamine (5-HT), a serotonergic receptor, may be an important factor associated with inducing the Bezold Jarish reflex (BJR) that may lead to the bradycardia and hypotension in the setting of decreased blood volume. OBJECTIVES This study aimed to investigate the effect of intravenous adminis...

BACKGROUND Postanesthetic shivering is one of the most common complications of anesthesia. We compared the efficacy of meperidine and two low doses of ketamine with placebo to prevent postanesthetic shivering after general anesthesia. METHODS This was a prospective, randomized double-blind placebo controlled clinical trial involving 120 ASA I-II patients aging 20-50 years, undergoing endoscop...

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, we...
