A Comparison of ESP Block to SSN Block for Analgesia in Shoulder Surgery

Overview

A comparison between Erector Spinae Plane block and Suprascapular nerve block in providing analgesia for shoulder surgery

Suprascapular nerve block is considered a phrenic nerve sparing approach that recently introduced as alternative for interscalene brachial plexus nerve block in shoulder surgery. However, some researchers reported that Suprascapular nerve block alone results in an ineffective analgesia. Erector Spinae Plane block is supposed to be able in providing adequate analgesia in shoulder surgery

The patients in group (a) will be placed in lateral decubitus. Then, an ultrasound-guided aseptic technique with a high-frequency linear transducer will be used to locate the transverse process of T2, where a needle will be inserted in a cephalocaudal direction until reaching the space between the fascia of the erector spinae and the transverse process of T2 and 30 ml of local anesthetic of bupivacaine 0.5% will be injected. * In group (b), SSC nerve block will be done as follow: In the suprascapular notch, an ultrasound-guided aseptic technique with a high-frequency linear transducer will be used. The linear probe, enveloped in a sterile sheath, will be placed parallel to the spine of the scapula to visualize it and then will be moved cephalic to the supraspinatus fossa. The probe will then be moved laterally up to the scapular notch, where the nerve will be identified by its round hyperechogenic shape 4 cm deep. * control group: patients will receive only general anesthesia

Outcomes

Primary Outcomes

Intraoperative analgesia

Recording of the patients' hemodynamics (heart rate and non-invasive blood pressure) and total dose of opioids consumption intraoperatively and postoperatively.

Time frame: The intraoperative patients' hemodynamics every 30 min were collected and analyzed till the end of surgery . Also the total dose of opioids consumed intraoperatively will be recorded. Postoperative consumed opioid for 24 hours also will calculated
