OBJECTIVES The aim of this randomized double-blind study was to investigate whether 20 microg of intrathecally administered fentanyl would influence the incidence and severity of shivering in patients undergoing cesarean section. MATERIAL AND METHOD Sixty healthy patients scheduled for cesarean section under spinal anesthesia using 2.2 ml of 0.5% hyperbaric bupivacaine with 0.2 ml of morphine...

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...

PURPOSE Postoperative nausea and vomiting (PONV) is a common complication after gynecological surgeries. This meta-analysis was conducted to evaluate the efficacy of dexmedetomidine on PONV after gynecological surgeries. METHODS Three main electronic databases including Pub Med, Embase and Cochrane Central Register of Controlled Trials for randomized controlled trials (RCTs) were searched by ...

BACKGROUND This prospective, randomized study was designed to compare remifentanil and magnesium sulphate during middle ear surgery in terms of postoperative pain and other complications. METHODS Eighty patients undergoing middle ear surgery were enrolled in the study. Patients were randomized into two groups of 40 to receive remifentanil (Group R) or magnesium sulphate (Group M) infusion. Pr...

background: this study was designed to investigate the effect of intravenous magnesium sulfate on hemodynamic changes induced by pneumoperitoneum in patients undergoing laparoscopic cholecystectomy. methods: a randomized, placebo controlled study was performed on 52 asa class i or ii aged 20-70 years patients undergoing laparoscopic cholecystectomy with pneumoperitoneum with carbon dioxide. bef...

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 hypothermia and shivering is a frequent event in patients during cesarean section under spinal anesthesia. We assessed the effect of preoperative warming during cesarean delivery under spinal anesthesia for prevention of hypothermia and shivering. METHODS Forty five patients undergoing elective cesarean section were randomly assigned to three groups. Group F received ...

Editor—We read with interest Wadhwa and colleagues’ paper about the use of magnesium sulphate to reduce the shivering threshold. We question whether there is any potential ‘real world’ use for this proposed therapy of high-dose magnesium in patients with myocardial ischaemia, either peri-infarction, periangioplasty or perioperative coronary bypass graft surgery. We agree that shivering is undes...

Dexmedetomidine (DEX) is currently being used as a premedication for anxiolysis, an adjunctive drug both during and after surgery adjunct to attenuate emergence agitation, postoperative pain, shivering. It alpha-2 agonist which 8 times more potent than clonidine also has sympatholytic effects1. in central neraxial blocks enhance the quality prolong duration of block2,3. Its use peripheral nerve...

OBJECTIVES Premedication with clonidine has been found to reduce the bleeding during endoscopic sinus surgery (ESS), therefore lowering the risk of surgical complications. Premedication is an essential part of pre-surgical care and can potentially affect magnitude of systemic stress response to a surgical procedure. The aim of this study was to compare the efficacy of premedication with clonidi...
