BACKGROUND The evidence that an infusion of a low dose of naloxone reduces post-operative pain and opioid analgesic consumption is somewhat conflicting. Thus, the aim of the present study was to investigate the effect of an ultra-low dose of naloxone on patient-controlled morphine analgesia. METHODS Ninety patients, 35-55 years old, scheduled for total(More)
BACKGROUND In this study, the effect of naloxone on duration of supraclavicular brachial plexus block was evaluated. It was hypothesized that naloxone can increase the duration of neural blockade. METHODS Sixty-eight patients scheduled for surgery under supraclavicular brachial plexus block were randomly assigned to receive 30 ml bupivacaine (Group C); 30(More)
BACKGROUND AND OBJECTIVES Postoperative bleeding has a great clinical importance and can contribute to increased mortality and morbidity in patients undergoing coronary artery bypass graft surgery. In this prospective, randomized, double-blind study, we evaluated the effect of prophylactic administration of fibrinogen concentrate on post-coronary artery(More)
INTRODUCTION Etomidate causes pain when injected intravenously. In this study we sought to determine if pretreatment by ondansetron reduces the pain on injection of etomidate. METHODS In this randomized, double blinded, placebo-controlled clinical trial, 20 patients of both sexes aged between 18 and 50 years of American Society of Anesthesiologists (ASA)(More)
Pain management is crucially important in the postoperative period as it increases patient comfort and satisfaction. The primary outcome of present study was to evaluate the effect of sufentanil added to hyperbaric bupivacaine solution 0.25% in transversus abdominis plane (TAP) block, on postoperative analgesic consumption. Fifty ASA physical status I-II(More)
OBJECTIVE Transversus abdominis plane (TAP) block is a recently introduced regional anesthesia technique that is used for postoperative pain reduction in some abdominal surgeries. The present study evaluated the efficacy of the TAP block on the post laparoscopic cholecystectomy pain intensity and analgesic consumption. METHODS Fifty-four patients were(More)
OBJECTIVE The primary outcome of this study was to evaluate the effect of adding sufentanil to hyperbaric bupivacaine on duration of sensory blockade of spinal anesthesia in chronic opioid users in comparison with non-addicts. METHODS Sixty patients scheduled for orthopedic surgery under spinal anesthesia were allocated into four groups: group 1 (no(More)
BACKGROUND AND OBJECTIVES Reducing pain on injection of anesthetic drugs is of importance to every anesthesiologist. In this study we pursued to define if pretreatment by granisetron reduces the pain on injection of etomidate similar to lidocaine. METHODS Thirty patients aged between 18 and 50 years of American Society of Anesthesiologists physical status(More)
BACKGROUND Anesthesia induction in patients with current substance abuse can be a challenge for anesthesiologists. OBJECTIVES This study aimed to evaluate the effect of adding Sufentanil to Bupivacaine on duration of brachial plexus nerve block. PATIENTS AND METHODS One hundred and twenty patients with (Groups C and D) and without (Groups A and B) a(More)
