BACKGROUND The analgesic nefopam does not compromise ventilation, is minimally sedating, and is effective as a treatment for postoperative shivering. The authors evaluated the effects of nefopam on the major thermoregulatory responses in humans: sweating, vasoconstriction, and shivering. METHODS Nine volunteers were studied on three randomly assigned days: (1) control (saline), (2) nefopam at...

The side effects of physostigmine, a tertiary amine anticholinesterase agent commonly used to treat postanaesthetic depression caused by a large number of drugs, are thought to be fairly mild. A case is reported in which atrial fibrillation followed a total dose of 2 mg of this drug to a patient who was slow in recovering from a general anaesthetic. The arrhythmia was self-limiting and required...

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, w...

Shivering associated with spinal anesthesia during Cesarean delivery is an uncomfortable experience for the parturient, which may also cause adverse effects. In this prospective, randomized, double-blind, placebo-controlled study, we sought to evaluate the effect of intrathecal dexmedetomidine, administered as an adjunct to hyperbaric bupivacaine for Cesarean delivery, on the incidence and seve...

BACKGROUND Shivering is among the common troublesome complications of spinal anesthesia (SA), and causes discomfort and discontentment in parturients undergoing cesarean sections (CSs). The aim of this study was to investigate the effects of intrathecal dexmedetomidine in the prevention of shivering in those who underwent CS under SA. SUBJECTS AND METHODS Fifty parturients planned for electiv...

a b c d d Aims: This randomized double blind study was carried out to investigate effect of intrathecal fentanyl on incidence and severity of intraoperative shivering on patients undergoing lower abdominal surgeries under spinal anesthesia. Method: 120 patients undergoing lower abdominal surgeries under spinal anesthesia were assessed in a randomized fashion. They were divided in to two groups....

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...

Postoperative administration of clonidine is an effective treatment for shivering. However, the ability of this drug to stop postanesthetic shivering when administered intraoperatively remains controversial. Furthermore, the relative efficacy of clonidine during isoflurane and propofol anesthesia remains unknown. We therefore evaluated the incidence of postanestbetic shivering in patients given...
