NCT03487874

Brief Summary

This study evaluates the effects of selective 8th cervical nerve root block during interscalene brachial plexus block on the relief of pain intensity upon the introduction of a posterior portal during arthroscopic shoulder surgery. The 5th to 7th cervical nerve roots will be blocked in half of participants, while the 5th to 8th cervical nerve roots will be blocked in the other half.

Outcome Measures

Primary Outcomes (1)

  • Pain intensity upon the introduction of a posterior portal

    0, 1, and 2 represent no pain, mild pain, and severe pain, respectively.

    50 minutes after interscalene block

Secondary Outcomes (18)

  • Sensory blockade

    30 minutes after interscalene block

  • Motor blockade

    30 minutes after interscalene block

  • Ipsilateral hemidiaphragmatic blockade

    Before interscalene block and 30 minutes after interscalene block

  • Horner's syndrome

    Before interscalene block and 30 minutes after interscalene block

  • Pulmonary function test

    Before interscalene block and 30 minutes after interscalene block

  • +13 more secondary outcomes

Study Arms (2)

Interscalene block with C8 root block

EXPERIMENTAL

The 5th to 8th cervical nerve root block under ultrasound guidance using 25 to 30 ml of 0.75% ropivacaine

Procedure: Interscalene block with C8 root blockDrug: 0.75% ropivacaine

Conventional interscalene block

ACTIVE COMPARATOR

The 5th to 7th cervical nerve root block under ultrasound guidance using 25 to 30 ml of 0.75% ropivacaine

Procedure: Conventional interscalene blockDrug: 0.75% ropivacaine

Interventions

Under ultrasound guidance, the 5th to 7th cervical nerve roots are blocked.

Conventional interscalene block

Under ultrasound guidance, the 5th to 8th cervical nerve roots are blocked.
