BACKGROUND AND AIMS Elective lower segment cesarean section under spinal anesthesia is frequently associated with shivering. Ondansetron has been shown to be effective for postspinal shivering. In the present study, we compare the efficacy of ondansetron to prevent postspinal shivering in parturients undergoing cesarean delivery under spinal anesthesia. MATERIALS AND METHODS A total of eighty...

Abstract Background Inadvertent perioperative hypothermia (IPH) defined as core temperature below 36.0 °C is a common complication of general anesthesia with prevalence up to 70%. Warming peripheral tissues prior induction reduces the central gradient, thereby minimizing heat loss due redistribution, after anesthesia. This study aimed evaluate effect prewarming on post-induction and incidence i...

Background and Aims Cesarean sections are performed mostly under spinal anesthesia. Shivering is one of the distressing complications. The aim of the study was to compare the efficacy of intravenous (i.v) magnesium sulfate and tramadol with placebo (normal saline) on postspinal shivering in elective cesarean section when used as prophylaxis. Methods One hundred and thirty-five pregnant women ...

BACKGROUND Shivering associated with spinal anesthesia is uncomfortable and may interfere with monitoring. The aim of this study is to evaluate the effect of ramosetron, a serotonin-3 receptor antagonist, on the prevention of shivering during spinal anesthesia. METHODS We enrolled 52 patients who were ASA I or II and who had undergone knee arthroscopy under spinal anesthesia. Warmed (37 degre...

Reportedly, during spinal anesthesia, the shivering threshold is reduced approximately 1 degree C but the vasoconstriction threshold remains normal. Such divergence between the shivering and vasoconstriction thresholds is an unusual pattern of thermoregulatory impairment and suggests that the mechanisms of impairment during regional anesthesia may be especially complex. Accordingly, we sought t...

BACKGROUND Shivering is one of the common problems in spinal anesthesia. The objective of the present study was to evaluate the effect of intrathecal fentanyl (25 µg) on incidence and severity of intraoperative and postoperative shivering. METHODS A double-blind randomized controlled study was conducted in eighty healthy women (ASA Physical status I) scheduled for elective cesarean section un...

a bstract background: shivering is a common complication of general and epidural anesthesia. warming methods and many drugs are used for control of shivering in the recovery room. the present study is a randomized clinical trial aimed to investigate the effects of two interventions in comparison with pethidine which is the routine treatment on shivering in patients undergoing abdominal surgery ...

PURPOSE The aim of this study was to evaluate the effect of dexmedetomidine on shivering during spinal anesthesia. METHODS Sixty patients (American Society of Anesthesiologists physical status I or II, aged 18-50 years), scheduled for elective minor surgical operations under spinal anesthesia with hyperbaric bupivacaine, were enrolled. They were administered saline (group C, n = 30) or dexmed...

conclusions the results of this study showed that ketamine and pethidine are both equally effective in the reduction of postoperative shivering. results there was no statistically significant difference between the shivering intensity in both groups. only regarding the shivering in the first minute after entering the recovery room, there was an obvious difference between ketamine and pethidine ...
