BACKGROUND Neuraxial anesthesia reduces the shivering threshold approximately 0.6 degrees C. This effect might be mediated by an apparent (as opposed to actual) increase in lower body temperature. Accordingly, sufficient lower body warming should result in thermoregulatory inhibition comparable to that exerted by epidural anesthesia. We tested the hypothesis that increasing leg skin temperature...

BACKGROUND Postoperative shivering is a major problem in children undergoing general anesthesia. OBJECTIVES The aim of the present study was to investigate the role of low-dose intravenous ketamine for prevention of shivering after induction of general anesthesia in children who had undergone tonsillectomy. PATIENTS AND METHODS This was a randomized, double-blinded, placebo-controlled trial...

from general and regional anesthesia. the incidence of this complication is reported to be 40-70% among patients. pas occurrence depends on various factors such as age, gender and drugs used in anesthesia and surgery time. granisetron is a serotonin 5ht3 receptor antagonist. beneficial effects of such drugs have been shown in a limited number of studies. in this study, preventive effects of gra...

aim and background:   adding new supplements when performing spinal anesthesia can increase the duration of analgesia. the aim of the present study has been to compare intrathecal midazolam and tramadol with the conventional method for postoperative pain and shivering control after elective caesarean section. methods and materials:   in this double-blind clinical trial, 210 asa class i,ii women...

BACKGROUND 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. METHODS This randomized placebo-controlled double blind clinical trial included 90 patients scheduled for elective gynecologic operations, rand...

Recent literature has demonstrated significant improvements in neurologic outcomes in patients who have received induced hypothermia in the setting of out-of-hospital cardiac arrest. Through multiple metabolic mechanisms, the induction of hypothermia slows the progression and devastation of transient cerebral hypoxia. Despite these benefits, the desired reduction in core temperature is often a ...

Objective: Postoperative shivering can cause patients serious adverse events and influence their outcomes after general anesthesia. To date there is no ideal drug which can be used to prevent post operative shivering. The aim of this randomized controlled trial was to examine the efficacy and accompanying side effects of prophylactic flurbiprofen along with parecoxib or placebo for reducing pos...

Neurons of the pontine tegmentum of the cat were lesioned by microinjection of ibotenic acid into the brainstem. The threshold ambient temperatures for heat-gain (shivering) and for heat-loss (panting) responses, together with brain and skin temperatures, were measured in intact animals and after the neurotoxic lesioning. After the lesioning the shivering threshold was altered but the panting t...
