Brief Summary

Suprascapular nerve is a mixed motor and sensory peripheral nerve arising from the superior trunk of brachial plexus.The suprascapular nerve runs through the posterior triangle of the neck, anterior of the trapezius muscle and dorsal of the omohyoid muscle, in direction of the scapula. Suprascapular nerve block is performed by anterior and posterior approach. Posterior approach of the suprascapular nerve block has been shown for many years to provide effective analgesia in the shoulder region for the chronic and acute pain. There are studies showing that suprascapular block with anterior approach provides effective analgesia in shoulder arthroscopy. The aim of our study was to compare anterior and posterior approaches of suprascapular nerve block in terms of analgesic efficacy and patient safety.

Outcome Measures

Primary Outcomes (1)

• Postoperative pain at the postoperatively 30 Minutes, 4 Hours, 6Hours, 12Hours, 24Hours

  Visual analogue scale (0-10): 0= no pain, 10= the worst pain ever feel.

  Up to 24 hours post-operative

Secondary Outcomes (11)

• Diaphragmatic movements

  Baseline (Before the block performed) and 30 minutes after the end of surgery

• Peroperatively opioid analgesic consumption (Remifentanil)

  up to postoperative 0 minutes

• Postoperative opioid analgesic consumption (morphine)

  postoperative 30 minutes

• Postoperative opioid analgesic consumption (morphine)

  postoperative 4 hours

• Postoperative opioid analgesic consumption (morphine)

  postoperative 6 hours
