BACKGROUND In this prospective, randomized, double-blind study, we verified the hypothesis that TEAS can alleviate remifentanil-induced hyperalgesia in patients undergoing thyroidectomy. METHODS 60 American Society of Anesthesiologists physical status (ASA) I-IIpatients, aged 18-60 year, scheduled for thyroidectomy were randomly allocated to TEAS or sham groups. TEAS consisted of 30 min of st...

Background: Paravertebral block has been established technique for providing analgesia to the chest and abdomen. We conducted the current study to compare single dose paravertebral block (PVB) versus single dose epidural blockade (EP) for pain relief after renal surgery Methods: Eighty patients scheduled for renal surgery were randomly assigned into two groups according to the analgesic techniq...

Introduction: Bupivacaine is used most commonly for spinal anesthesia, however the major concern longer duration and cardiotoxicity, that led us to find safe alternative with shorter duration. Hence, we compared routinely hyperbaric bupivacaine recently available ropivacaine in terms of block characteristics caesarean section (CS).Objective: To compare efficacy safety anesthesia elective CS pri...

Objective: In this double-blind prospective clinical study, we investigated the eff ects of fentanyl and dexmedetomidine as adjuvant agents in supratentorial craniotomies on the following: hemodynamic changes during perioperative and recovery periods, brain edema perioperatively, recovery times and side eff ects, such as hypertension, shivering, nausea and vomiting.

BACKGROUND: Potentiating the effect of intrathecal local anesthetics by addition of intrathecal opiods for intra-abdominal surgeries is known. In this study by addition of fentanyl we tried to minimize the dose of bupivacaine, thereby reducing the side effects caused by higher doses of intrathecal bupivacaine in cesarean section. METHODS: Study was performed on 120 cesarean section parturients ...
