NCT01589354

Brief Summary

This study evaluates two anaesthetic techniques namely interscalene brachial plexus block and intra-articular local anaesthetic injection. Both techniques are currently used for providing postoperative pain relief following arthroscopic shoulder stabilisation operation. It will be a randomised controlled trial involving 30 patients in two groups.

Outcome Measures

Primary Outcomes (1)

  • Mean pain score over the first 24 hours following arthroscopic shoulder stabilisation operation

    24 months

Secondary Outcomes (2)

  • Post-operative analgesic requirements in the first 24 hours after surgery

    24 months

  • Patient assessment of quality of analgesia and identifying any complications as a result of the two anaesthetic procedures

    24 months

Study Arms (2)

Interscalene brachial plexus block

EXPERIMENTAL
Procedure: Interscalene brachial plexus blockDevice: Ultrasound guided techniqueDrug: Ropivacaine

Intra-articular injection

EXPERIMENTAL
Procedure: Intra-articular Ropivacaine injectionDrug: Ropivacaine

Interventions

An interscalene block will be performed pre-operatively using ultrasound guidance and the peripheral nerve stimulator (with the patient awake) using 20 ml of 0.375% Ropivacaine.

Interscalene brachial plexus block

The procedure will be done by the surgeon at the end of the operation, with an intra-articular injection of 20 ml 0.75% Ropivacaine through the arthroscopic cannula after closure of the anterior wound

Intra-articular injection

The block will be performed under U/S guidance

Interscalene brachial plexus block
