Background Shivering is a frequent and undesirable complication of spinal anesthesia. It is a physiologic response to increase the body core temperature in an attempt to raise metabolic heat production. However, shivering may trigger myocardial ischemia; increase intraocular and intracranial pressures, increase wound pain, delay wound healing and interfere with pulse rate, blood pressure and el...

BACKGROUND Shivering related to spinal anesthesia may interfere with monitoring and is uncomfortable. The aim of the present study was to investigate low-dose intrathecal meperidine for the prevention of shivering after induction of spinal anesthesia in parturients with cesarean section. METHODS This was a prospective randomized, double-blind, placebo-controlled trial including 100 parturient...

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...

Spinal anesthesia significantly results in shivering and hypothermia as unwanted effect. Shivering increases oxygen consumption which may be deleterious patients who have low cardiac pulmonary reserve. We conducted this study to evaluate the efficacy of Ketamine Granisetron for prevention under spinal anesthesia. In randomized prospective study, 90 Patients aged 18-60 years ASA physical status ...

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...

Aims: Postoperative shivering is unpleasant and annoying for the patient, occurring in up to 65% of cases undergoing general anesthesia. Various mechanisms were suggested postoperative shivering. Shivering after anesthesia can cause complications, such as cardiovascular conditions, bleeding, infection. This study compared effects dexamethasone, pethidine, ketamine on prevention Methods & Ma...

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 ond...
