Brief Summary

Shoulder arthroscopic surgery is associated with moderate to severe postoperative pain, which may hinder early mobilization and functional recovery. Interscalene block (ISB) is commonly used to provide effective analgesia but is frequently associated with hemidiaphragmatic paralysis due to phrenic nerve involvement. Cervical erector spinae plane block (ESPB) has been proposed as an alternative regional technique that may provide analgesia while reducing respiratory-related adverse effects. This randomized controlled trial aims to compare the analgesic efficacy and safety of cervical ESPB versus continuous ISB in patients undergoing shoulder arthroscopic surgery.

  Postoperative pain intensity will be assessed using a 0-10 visual analogue scale (VAS) at 2, 6, 12, and 24 hours after surgery.

  2 hour, 6 hours, 12 hours, and 24 hours postoperatively

Secondary Outcomes (6)

• Motor blockade severity

  Up to 48 hours postoperatively

• analgesic consumption

  48 hours

• Adverse events

  7 days

• Duration of motor blockade

  Up to 48 hours postoperatively

• Sensory blockade distribution

  Up to 48 hours postoperatively

Study Arms (3)

Continuous Cervical Erector Spinae Plane Block

EXPERIMENTAL

Participants will receive an ultrasound-guided continuous cervical erector spinae plane block with perineural catheter placement as part of a standardized multimodal analgesia regimen for shoulder arthroscopic surgery. Postoperative analgesia will be provided via continuous local anesthetic infusion through the catheter per institutional protocol.

Procedure: Continuous Cervical Erector Spinae Plane Block

Continuous Interscalene Block

ACTIVE COMPARATOR

Participants will receive an ultrasound-guided continuous interscalene block with perineural catheter placement as part of a standardized multimodal analgesia regimen for shoulder arthroscopic surgery. Postoperative analgesia will be provided via continuous local anesthetic infusion through the catheter per institutional protocol.

Procedure: Continuous Interscalene Block

Single-Shot Interscalene Block

OTHER

Observational

Procedure: No intervention

Interventions

Continuous Cervical Erector Spinae Plane Block PROCEDURE

An ultrasound-guided cervical erector spinae plane block with catheter placement will be performed. Local anesthetic will be administered through the catheter to provide continuous postoperative analgesia according to institutional protocol as part of a standardized multimodal analgesic regimen.
