No results posted yet for this study

Summary

The aim of the study is to compare the diaphragmatic excursion and postoperative analgesia in the extrafascial versus intrafascial Interscalene brachial plexus block in patients undergoing shoulder arthroscopy.

Conditions

  • Arthroscopy
  • Analgesia
  • Intrafascial Interscalene Brachial Plexus Block

Interventions

PROCEDURE

Intrafascial interscalene brachial plexus block

After sterilization of skin with povidone-iodine (betadine) and skin infiltration with 1-3ml lidocaine 1%, interscalene brachial plexus block will be performed using an ultrasound machine (Phillips Cx-50,Amsterdam, Netherlands) with a linear probe (L12-3 MHz) will be used in both groups. The US transducer will be placed under aseptic fashion on the lateral side of the neck at the cricoid cartilage level to view three hypoechoic structures, that represent the roots of the brachial plexus. The two outermost nerve roots (C5 and C6) between the anterior and the middle scalene muscles will be identified and the local anesthetic (10 ml 0.5% bupivacaine) is then injected, so that spread will be seen immediately between the C5 and the C6 nerve roots.

PROCEDURE

Extrafascial interscalene brachial plexus block group

Final needle tip position will be 4 mm lateral to the brachial plexus sheath, at a level equidistant between C5 and C6 roots. The distance of 4 mm is chosen according to the calculated success rate over 90% reported. the local anesthetic (10 ml 0.5% bupivacaine) is then injected
