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. ...

Results: Excluding intercostobrachial nerve, the adequate sensory and motor block rates in group AX on the nerves of brachial plexus were found to be 100% and 92%-100%, respectively. Sensory and motor block rates were both found to be 96%-100% in group SC and also 80%-100%, and 88% in group IS, respectively. In terms of sensory and motor block evaluation of all the nerves, there were statistica...

BACKGROUND A prospective, double blind study was performed to compare the clinical effect of vertical infraclavicular and supraclavicular brachial plexus block using a nerve stimulator for upper limb surgery. METHODS One hundred patients receiving upper limb surgery under infraclavicular or supraclavicular brachial plexus block were enrolled in this study. The infraclavicular brachial plexus ...

INTRODUCTION Benefits of regional anesthesia can be prolonged by adding adjuvants to local anesthetics. This study was designed to test the efficacy of adding nalbuphine to bupivacaine in supraclavicular brachial plexus blockade using ultrasound (US) guidance. METHODOLOGY This was a prospective, randomized, double-blind study involving sixty patients of either sex undergoing elective orthoped...

Methods. A maximum of 20 volunteers were included to receive an ultrasound-guided sciatic nerve block with mepivacaine 1.5% and a starting volume of 0.2 ml mm cross-sectional nerve area. In cases of a complete sensory block, the volume was reduced by 0.02 ml mm cross-sectional nerve area until the first block failed. Thereafter, the volume of local anaesthetic was increased by 0.02 ml mm cross-...

Background And Aims: Brachial plexus block is the cornerstone of regional anaesthesia practice. Various adjuncts have been used as adjuvants to ropivacaine in the past. This study was done to see the effect on duration of analgesia using dexmedetomidine as adjuvant to ropivacaine 0.5% in supraclavicular brachial plexus block (SBPB). Method: A total of eighty patients undergoing elective upper l...

BACKGROUND In clinical practice, the level of sensory block in spinal anesthesia in opium abusers is lower than that in non-abusers because of adaptive changes caused by opium use. OBJECTIVES The aim of this study was to investigate the level of sensory block resulting from the intrathecal administration of 0.5% bupivacaine in opium abuser patients undergoing lower extremity and lower abdomin...

BACKGROUND Although spinal bupivacaine may have too long duration to be useful in the ambulatory setting, recent animal data suggest that lidocaine added to spinal bupivacaine may reduce the duration of bupivacaine spinal anesthesia. We explored whether lidocaine added to spinal bupivacaine could shorten the duration of bupivacaine spinal anesthesia in humans similarly to what has been reported...
