About

This study will answer the question whether there is a difference in the effects and complication rates of ultrasound guided continuous interscalene block (CISB) and nerve stimulation-guided continuous cervical paravertebral block (CCPVB). The aim of this study is to evaluate the differences in efficacy and side effects - if any.

Full description

This is a prospective randomized double-blinded study that will compare two commonly used approaches for the continuous blockade of the brachial plexus: the CCPVB, which focusses on the six cervical nerve root (C6 root), and CISB, which focuses on the upper trunk of the brachial plexus. Data of sensory testing, motor strength, shoulder pain, phrenic nerve function, recurrent laryngeal nerve (RNL) function, ipsilateral Horner's syndrome, block time and medication doses used for block placement, will be collected. All observations and measurements will be made by a member of the research team who is unaware of patient allocation to any particular group.

Enrollment: 53 patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria:

• The general inclusion will be those adult patients who:

  • are between the ages of 18 and 80 years
  • have an ASA Health Classification of I, II, or III
  • are scheduled for shoulder arthroplasty or rotator cuff repair surgery
  • Patients with a BMI of =to/< 40 Exclusion

The Exclusion criteria will include:

• Patient refusal to participate in the study or sign informed consent

• Patients with a BMI >40

Trial design

53 participants in 2 patient groups

ultrasound-guided CISB

Description:

Group 1 will receive ultrasound-guided CISB with the catheter placed on the upper trunk of the brachial plexus

nerve stimulator-guided CCPVB

Description:

Group 2 will receive landmark with nerve stimulator based needle placement and then nerve stimulator-guided CCPVB with the catheter placed on the 6th cervical spinal root

Treatment:

Device: nerve stimulator-guided CCPVB
