OBJECTIVE To test the hypothesis that identification and blockade of the intercostobrachial nerve (ICBN) can be achieved under ultrasound (US) guidance using a small volume of local anesthetic. METHODS Twenty-eight adult male volunteers were examined at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from November 2012 to September 2013. Intercostobrachial nerve blockade was ...

Background and Aims The aim of the study was to evaluate the effectiveness of epidural volume extension (EVE) technique in terms of sensory and motor block characteristics along with hemodynamic parameters as a part of combined spinal-epidural anesthesia (CSEA). Materials and Methods A total of 60 patients undergoing hip surgeries were assigned to one of the two groups containing 30 patients ...

BACKGROUND AND THE PURPOSE OF THE STUDY Opioids are usually used in regional anesthesia, with or without local anesthetics to improve the regional block or postoperative pain control. Since no data are available on fentanyl's effect on the onset time of lidocaine interscalene anesthesia, the purpose of this study was to examine its effect on the onset time of sensory and motor blockade during i...

A double-blind comparison of carbonated bupivacaine and bupivacaine hydrochloride in extradural anaesthesia was performed in 40 patients. No significant differences in the onset times, sensory blockade, motor blockade and duration of anaesthesia were demonstrated. Carbonated bupivacaine does not appear to offer any advantage over the hydrochloride salt for extradural anaesthesia.

Purpose: In this study we sought to determine if and when a difference exists with regards to differential sensory blockade between spinal and epidural anaesthesia using lidocaine. Methods : Ten healthy volunteers were randomly assigned to receive both spinal and epidural anaesthesia. Nonepinephrine containing solutions of lidocaine, 100 mg lidocaine 5% with 7.5% dextrose (spinal) and 600 mg li...

Three millititre of 0.75% plain bupivacaine and 0.5% amethocaine 3 ml in 5% glucose were used for spinal anaesthesia and compared in a double-blind study of 20 patients undergoing urological surgery. The onset time to maximum cephalad spread of sensory analgesia was approximately 45 min for bupivacaine and approximately 30 min in the amethocaine group (ns). The mean maximum spread of sensory an...

INTRODUCTION The ultrasound-guided transversus abdominis plane (TAP) block is used to treat postoperative pain after abdominal surgery. Abdominal wall sensory nerves are anaesthetised by injecting local anaesthetics into the neurofascial plane between the internal oblique and the transversus abdominis muscles. Sensory assessment of a TAP block may guide the decision on the extent of the block. ...

BACKGROUND In what way volume, concentration and dose affect block duration is controversial. The purpose of the present study is to investigate the effect of dose, volume and concentration of mepivacaine on the duration of sensory and motor blockade in ultrasound-guided single shot axillary brachial plexus blockade. METHODS In this parallel group randomized trial conducted in the Sint Maarte...
