Brief Summary

Evaluation of shoulder anterior capsule nerve block combined with suprascapular nerve block as an adequate sole anesthetic technique in shoulder arthroscopic surgeries without significant affection of motor power and pulmonary function.

Conditions

Regional Anesthesia for Shoulder Surgery

Outcome Measures

Primary Outcomes (3)

• Assessment of SHAC block efficacy for postoperative analgesia in shoulder arthroscopic surgeries by using Visual Analogue Scale (VAS)

  Inter-operative VAS immediately after the block and every 5 minutes for 30 minutes and every 2 hours post-operatively for 24 hours while 0 indicates no pain and 10 the severest pain.

  From start of surgery and for the 1st 24 hours postoperatively.

• Assessment of SHAC block efficacy for postoperative analgesia in shoulder arthroscopic surgeries by duration of analgesia

  Assessment of SHAC block efficacy for postoperative analgesia in shoulder arthroscopic surgeries by duration of analgesia. Duration of postoperative analgesia (from the time of patient recovery till the time of rescue analgesia).

  24 hours postoperatively

• Assessment of SHAC block efficacy for postoperative analgesia in shoulder arthroscopic surgeries by amount of opioid consumption postoperatively.

  Assessment of SHAC block efficacy for postoperative analgesia in shoulder arthroscopic surgeries by amount of opioid consumption postoperatively. Total dose of morphine per mg used during the 1st 24 hours postoperatively.

  1st 24 hours postoperatively.

Secondary Outcomes (2)

• Safety of SHAC block by monitoring of complications eg. local anesthetic toxicity , hemodynamics instability, phrenic nerve affection, pneumothorax.

  From start of surgery and for the 1st 24 hours.

• Patient satisfaction with the anesthesia and analgesia during and after surgery

  From start of surgery and for the 1st 24 hours postoperatively.
