Abstract
Brachial plexus blocks are useful and widely used for anaesthesia and postoperative pain control for upper limb surgery. Several approaches have been used; each of them has its own advantages and disadvantages. The supraclavicular nerve block is the easiest and ideal, as it blocks most of the branches of the brachial plexus, and this results in rapid onset and high success rates for surgery and analgesia of the upper limb surgery (with the exception of the shoulder). The success of brachial plexus blocks was greatly improved with the introduction of ultrasound (US)-guided techniques, by allowing the anaesthesiologist to visualize the brachial plexus and needle during injection, and this can reduce the incidence of complications. Nowadays, many adjuvant drugs have been used with local anaesthetic drugs to obtain rapid, intense and prolonged brachial plexus block. The aim of this study was to evaluate the effect of addition of either morphine or hyaluronidase to local anesthetic (L.A) mixture during sonar guided supraclavicular brachial plexus block. This evaluation included the onset of the block, duration of the block, quality of anesthesia and post operative pain. This prospective double blinded randomized controlled study was carried out in Tanta university hospital in Orthopedic & general surgery Departments on 75 patients from August 2019 to August 2020 scheduled to undergo acute or elective surgery of the elbow, forearm, and hand in awake anesthesia of either sex, age between 18-60 years belonging to ASA physical status I - II during sonar guided supraclavicular brachial plexus block.
