No results posted yet for this study

Summary

The study compares between the success rate of interscalene block and upper trunk block performed by anesthesia trainee for intra and postoperative analgesia during shoulder arthroscopy. The duration of performing the block, guidance intervention by the consultant and block failure will be recorded.

Conditions

  • Anesthesia, Local
  • Shoulder Pain

Interventions

PROCEDURE

Interscalene brachial plexus block combined with general anesthesia

Baseline diaphragmatic assessment will be performed before the nerve block in the sitting position. Interscalene block will be done as follows. US probe will be placed slightly lower to the level of the cricoid cartilage, followed by scanning of the neck to search for C5 and C6 nerve roots enclosed between the anterior and middle scalene muscles. The needle will be introduced in-plane from lateral to medial through the middle scalene muscle until the tip enters the brachial plexus sheath between the C5 and C6 roots, where LA will be injected. Patients will be transported to the operation room where general anaesthesia will be induced with tracheal intubation Fentanyl (0.5 μg/kg) will be given to maintain the heart rate and mean blood pressure 20% lower than preinduction values. Intravenous 1 gram paracetamol and 8 mg dexamethasone will be given to all patients as part of multimodal analgesia

PROCEDURE

Upper trunk brachial plexus block combined with general anesthesia

Baseline diaphragmatic assessment will be performed before the nerve block in the sitting position like the the ISB group Upper trunk will be visualized distal to the convergence of the C5 and C6 nerve roots but proximal to the departure of the suprascapular nerve (This nerve is a small hypoechoic circle that depart the lateral aspect of the upper trunk and courses posterolateral under the omohyoid muscle). The needle will be introduced in-plane from lateral to medial under the deep cervical fascia and through a very small portion of the middle scalene muscle, until the needle tip lies adjacent to the upper trunk, LA will be distributed below and above the upper trunk. Scanning for the upper trunk can be started from the supraclavicular fossa and moving proximal or opposite to cricoid cartilage and moving distal. The following steps will be done as in the ISB group
