Brief summary

Shoulder arthroscopy is a minimally invasive procedure frequently used for rotator cuff repair. Patients may experience severe postoperative (PO) pain, that can last for a month and can influence successful rehabilitation. Our study aimes to evaluate the effectiveness of interscalene brachial plexus single-shot (ISBSS) versus continuous interscalene brachial plexus block (ISBC) in controlling perioperative pain and avoiding PO pain chronicization. This prospective randomized unblinded trial hypothesizes that the PO perineuronal infusion using a continuous ambulatory delivery device pump gives better pain control and outcomes than ISBSS during the long-term follow-up period.

Detailed description

Blocks will be performed under ultrasound guidance with 15 - 20 mL of 0.75 % ropivacaine.

Interventions

PROCEDUREthe ISBC group, SonoPlex needle and E-catheter

in the ISBC group, a 22G 50 mm SonoPlex needle with an indwelling cannula will be used. The E-catheter will be inserted into the indwelling cannula.

PROCEDUREsingle bolus injection

An ultrasound-guided peripheral nerve block puncture will be performed from the lateral to the medial side of the neck. In this group a 22G 50 mm needle will be used
