Abstract
Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.
Brachial Plexus Block for upper extremity surgery provides superior analgesia and reduces opioid consumption. Painful procedures previously requiring inpatient hospital admission for pain control are now commonly performed as ambulatory procedures.
A variety of local anesthetic adjuncts have been studied in an attempt to prolong the effects of single-injection peripheral nerve blockade. Among these adjuncts, dexamethasone has gained considerable interest several studies have reported that dexamethasone prolongs the analgesic duration of Brachial Plexus Block regardless of the route of administration.
Ultrasound has become the cornerstone of peripheral nerve blocks in upper limb surgeries. It provides better visualization of the LA spread, reduces the LA dose and improves the quality of block.
The aim of this study was to compare the effect of perineural versus intravenous dexamethasone on the outcomes of a single-shot ultrasound-guided supraclavicular brachial plexus block with plain bupivacaine 0.5% in upper limb surgeries below the shoulder as regards hemodynamic parameters, onset and duration of the block and postoperative analgesic requirements.
This study was carried out at Menoufia University Hospitals on 90 ASA I & II adult patients scheduled for elective upper limb surgeries below the shoulder using ultrasound guided supraclavicular block.
