BACKGROUND During head and neck surgery including orthognathic surgery, mild intraoperative hypothermia occurs frequently. Hypothermia is associated with postanesthetic shivering, which may increase the risk of other postoperative complications. To improve intraoperative thermoregulation, devices such as forced-air warming blankets can be applied. This study aimed to evaluate the effect of supp...

BACKGROUND Postoperative nausea and vomiting (PONV), postanesthetic shivering and pain are common postoperative patient complaints that can result in adverse physical and psychological outcomes. Some antiemetics are reported to be effective in the management of postoperative pain and shivering, as well as PONV. We evaluated the efficacy of dexamethasone added to ramosetron on PONV, shivering an...

BACKGROUND Surgery and anaesthesia cause shivering due to thermal dysregulation as a compensatory mechanism and is worsened by vasodilatation from spinal anaesthesia that redistributes core body heat. Due to paucity of data Mulago Hospital's post spinal shivering burden is unknown yet it causes discomfort and morbidity. METHODS Ethical approval was obtained to perform the study among consenti...

Introduction: Shivering is a common side effect of central neuraxial anaesthesia. Intravenous pethidine commonly used in reducing shivering but has been associated with significant opioid effects. Dexamethasone as powerful anti-inflammatory and analgesia agent postulated to inhibit inflammatory mediators’ release thus inhibiting thermoregulatory centre, potentially attenuating post spinal shive...

FEW physiologic functions are so well guarded as the thermoneutral zone. It is kept within a narrow limit of 0.2°C via most sophisticated sensing/effector mechanisms. This way, optimal working conditions for the cellular machinery are preserved. During anesthesia, the thermoneutral zone widens by a factor of 10. Therefore, protective measures to prevent heat loss, such as vasoconstriction, may ...
