BACKGROUND AND AIMS The primary aim of this study was to evaluate the effect of addition of dexmedetomidine on the duration of analgesia in patients undergoing upper limb surgeries under supraclavicular brachial plexus block. MATERIAL AND METHODS Sixty patients of American Society of Anesthesiologists physical status I/II/III undergoing elective upper limb surgeries under supraclavicular brac...

Background and objectives: We performed a prospective randomized double-blinded study evaluating if a reduced volume of local anesthetic would result in operative limb surgical anesthesia while decreasing motor paralysis during an ultrasound-guided supraclavicular nerve block. Current tendencies in clinical practice towards smaller injectate volumes during ultrasound-guided nerve block placemen...

Different additives have been used to prolong regional blockade. We designed a prospective, randomized, double-blind study to evaluate the effect of dexamethasone added to lidocaine on the onset and duration of axillary brachial plexus block. Sixty patients scheduled for elective hand and forearm surgery under axillary brachial plexus block were randomly allocated to receive either 34 mL lidoca...

BACKGROUND Infraclavicular brachial plexus block is an appropriate approach for distal arm and forearm surgeries. Local anesthetic adjuvant agents are used to improve the quality of nerve blocks. Dexmedetomidine and ketorolac are two different types of adjuvants, which have been used in some studies. OBJECTIVES The purpose of this study was to examine the effects of dexmedetomidine and ketoro...

The present study was designed to assess the efficacy of fentanyl and pancuronium combined with dilute lidocaine solution for axillary block. Onehundred adult patients undergoing upper limb surgery were randomly allocated to receive either 0.6 mL/kg of 1 % lidocaine (6 mg/kg) or 0.6 mLlkg of 0.5% lidocaine (3 mg/kg) with 1 µg/kg of fentanyl and 0.5 mg of pancuronium. The onset of sensory a...

Objectives: To evaluate the sensory and motor block of continuous spinal anesthesia compared to epidural anesthesia in mild to moderate preeclamptic patients undergoing cesarean section. Methods: 40 mild to moderate preeclamptic patients undergoing cesarean section under regional anesthesia. Patients are randomly allocated into 2 groups, CSA group (n=20) received continuous spinal anesthesia us...

INTRODUCTION Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better loca...

The pathophysiological mechanisms responsible for conduction block in multifocal motor neuropathy (MMN) are still unclear. To clarify the physiological abnormalities at the site of the block, we tested the effects induced by polarizing direct currents on motor conduction along forearm nerves in 25 normal nerves (13 subjects), and at the site of conduction block in six nerves (five patients) wit...
