background opium is a highly addictive agent and the most common narcotic often misused in iran. the pharmacokinetic of anesthetic drugs in patients with opium addiction is one of the great challenges for anesthesiologists. hemodynamic instability and postoperative side effects are of these challenges which should be managed correctly. objectives in this study we aimed to assess the effects of ...

 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 u...

background: the postoperative shivering is one of the common complications of anesthesia after surgery and in the recovery room, which can cause the increased systemic blood pressure, oxygen consumption, heart rate and the cardiac arrhythmias among patients. due to the variety of drugs used in general anesthesia, and necessity of choosing the effective intravenous and the inhaled drugs to reduc...

Introduction: The aim of this study was to investigate low-dose intrathecal meperidine for prevention or alleviation of shivering after induction of spinal anesthesia for transurethral resection of the prostate (TURP). Materials and Methods: In a randomized controlled trial, 80 patients scheduled for TURP under spinal anesthesia were assigned into two groups of case and control. Spinal anesthes...

BACKGROUND One of the unpleasant side effects of general anesthesia is shivering in the process of recovery. It is an involuntary oscillatory mechanical movement that can be classified as clonic movements. These movements can affect one or several groups of skeletal muscles beginning from 5 to 30 minutes after the discontinuation of anesthesia. OBJECTIVES We aimed to study ketamine's effect o...

BACKGROUND The optimum dose of dexmedetomidine for shivering control with the least hemodynamic derangements is still under research. OBJECTIVE To compare the efficacy, hemodynamic and side effects of dexmedetomidine in 3 different doses with those of meperidine for the treatment of shivering in patients undergoing spinal anesthesia for minor elective lower abdominal surgery. STUDY DESIGN P...

BACKGROUND Shivering is a common postanesthesia adverse event with multiple etiologies. At present tramadol is a widely used drug for the control of shivering. However, tramadol may cause a lot of nausea and vomiting. Hence, the need to find a better drug with less of side effects. The aim of this study was to compare the efficacy of dexmedetomidine and tramadol in the treatment of post-spinal ...
