Meta Analysis
Efficacy and safety of ondansetron in preventing postanesthesia shivering: a meta-analysis of randomized controlled trials.
Shivering is a very common complication in the postanesthesia period. Increasing studies have reported ondansetron may be effective in prevention of postanesthesia shivering (PAS). However, the results remained controversial; hence we conducted a meta-analysis of randomized controlled trials to evaluate the efficacy and safety of ondansetron on the prevention of postanesthesia shivering. ⋯ Ondansetron has a preventive effect on PAS without a paralleled side effect of bradycardia.

Review Meta AnalysisEfficacy spectrum of antishivering medications: meta-analysis of randomized controlled trials.
Shivering after anesthesia or in the critical care setting is frequent, can be prolonged, and has the potential for serious adverse events and worsening outcomes. Furthermore, there are conflicting published data and clinical protocols on how to best treat shivering. In this study, we aimed to critically analyze the published evidence of antishivering medications. ⋯ There is significant heterogeneity in the literature with respect to study methods and efficacy testing of antishivering treatments. Clonidine, meperidine, tramadol, nefopam, and ketamine were the most frequently reported pharmacological interventions and showed a variable degree of efficacy in randomized, double-blinded, placebo-controlled trials.

Randomized Controlled Trial Clinical TrialOndansetron given before induction of anesthesia reduces shivering after general anesthesia.
The neurotransmitter pathways involved in the mechanism of postanesthetic shivering (PAS) are poorly understood. Meperidine, clonidine, and physostigmine are all effective treatments, indicating that opioid, alpha(2)-adrenergic, and anticholinergic systems are probably involved. We investigated the effect of ondansetron, a 5-HT(3) antagonist used to treat postoperative nausea and vomiting, on intraoperative core and peripheral temperatures and PAS. Eighty-two patients (age, 18-60 yr) undergoing orthopedic, general, or urological surgery were randomized into three groups in this double-blinded, placebo-controlled, study: Group O4 (n = 27) received ondansetron 4 mg IV, Group O8 (n = 27) received ondansetron 8 mg IV, and Group C (n = 28) received saline IV immediately before the anesthetic induction. Core (tympanic) and fingertip temperature (dorsum of middle finger) were recorded. Anesthesia was induced with IV fentanyl 1 microg/kg and propofol 2.0-2.5 mg/kg and maintained with 1 minimum alveolar anesthetic concentration isoflurane in 70% nitrous oxide/oxygen. The occurrence of shivering was documented clinically during recovery by nursing staff, who were unaware of the group assignment. PAS occurred in 16 of 28 (57%) patients in Group C, compared with 9 of 27 (33%) in Group O4 (P = 0.13) and 4 of 27 (15%) patients in Group O8 (P = 0.003). Within each group, core temperature decreased and peripheral temperature increased significantly, but there were no significant differences among the groups at any time interval. We conclude that ondansetron 8 mg IV given during the induction of anesthesia prevents PAS without affecting the core-to-peripheral redistribution of heat during general anesthesia. This suggests that serotonergic pathways have a role in the regulation of PAS. ⋯ In a randomized, double-blinded, placebo-controlled, clinical study, ondansetron 8 mg IV, given just before the induction, reduced the incidence of postanesthetic shivering compared with saline. The anticipated core-to-peripheral redistribution of body temperature during general anesthesia was not affected. This implies that ondansetron probably acts by a central inhibitory mechanism, and that 5-hydroxytryptaminergic pathways have a role in regulating postanesthetic shivering.

Randomized Controlled TrialEfficacy of granisetron in preventing postanesthetic shivering.
Recently, 5-hydroxytryptamine 3 (5-HT3) receptor antagonists have been reported to prevent postanesthetic shivering. This placebo-controlled study was performed to evaluate the efficacy of granisetron, a 5-HT3 antagonist, in comparison with meperidine and tramadol in preventing postanesthetic shivering. ⋯ The prophylactic use of granisetron 40 microg/kg is as effective as meperidine (0.4 mg/kg) and tramadol (0.1 mg/kg) in preventing postanesthetic shivering without prolonging the emergence time from anesthesia.

Randomized Controlled TrialOndansetron and meperidine prevent postoperative shivering after general anesthesia.
Postoperative shivering is one of the common problems following general anesthesia and may lead to multiple complications. The aim of this study was to examine the preventive effects of Ondansetron and Meperidine on postoperative shivering. ⋯ Ondansetron can effectively reduce post operative shivering.

Review Randomized Controlled Trial
Ondansetron does not reduce the shivering threshold in healthy volunteers.
Ondansetron, a serotonin-3 receptor antagonist, reduces postoperative shivering. Drugs that reduce shivering usually impair central thermoregulatory control, and may thus be useful for preventing shivering during induction of therapeutic hypothermia. We determined, therefore, whether ondansetron reduces the major autonomic thermoregulatory response thresholds (triggering core temperatures) in humans. ⋯ /b>. Ondansetron appears to have little potential for facilitating induction of therapeutic hypothermia.

Randomized Controlled TrialComparison of ondansetron and meperidine for prevention of shivering in patients undergoing spinal anesthesia.
Perioperative hypothermia is a common problem in anesthesia practice. Regional anesthesia, like general anesthesia, influences the thermoregulatory process. The aim of our study was to compare the efficacy of ondansetron and meperidine in the prevention of shivering during and after spinal anesthesia. ⋯ Ondansetron and meperidine have similar anti-shivering effects. In addition, both ondansetron and meperidine altered the correlation between the core temperature and block level during spinal anesthesia.
