A Novel Combination of Peripheral Nerve Blocks for Patients Scheduled for Shoulder Surgery

Interscalene block has been the traditional regional anesthesia for shoulder surgery and postoperative pain. However, the risk of phrenic nerve palsy and irreversible nerve injury have encouraged search for alternative methods.

About this study

Analyzing block effects of the lateral sagittal infraclavicular brachial plexus block(posterior and lateral chord), the investigators found it affecting all shoulder relevant nerves , except for the suprascapular and the supraclavicular nerves.

Accordingly, by combining a superficial cervical plexus block, suprascapular nerve block and block of the posterior and lateral chords infraclavicularly, the investigators believe this novel combination would provide anesthesia for patients scheduled for shoulder surgery.

Treatment and study plan

Nerve Block

Procedure

Nerve block: 31 ml ropivacaine 7.5 mg/ml (Lateral sagittal infraclavicular brachial plexus block) + 4 ml ropivacaine 5 mg/ml (suprascapular nerve block) + 5 ml ropivacaine 5 mg/ml (superficial cervical plexus block)

Primary outcomes

  1. The need for general anaesthesia

    Time frame: Intraoperatively

    Investigators will record the number of patients who need to be converted to general anaesthesia

Secondary outcomes

  1. Surgeons satisfaction with the working conditions

    Time frame: Intraoperatively

    Graded in a) Good and b) Poor
