Brief Summary
The erector spinae plane (ESP) block has been studied for analgesia in shoulder surgery as a phrenic nerve-sparing alternative. However, successful ESP catheter placement appears multifactorial, with failure mechanisms including lamination, plane collapse, or catheter overcoiling. Electrical stimulation (ES) is a common technique used in regional anesthesia to detect possible intraneural placement. ES of the erector spinae muscle complex may objectively guide proper interfascial catheter placement and improve local anesthetic spread. The primary goal of this study is to establish if ESP catheter placement with the addition of ES to ultrasound (US) guidance facilitates accurate catheter placement. This study will further characterize postoperative analgesia and the incidence of brachial plexus stimulation for patients who receive ES-assisted ESP catheter placement.

Outcome Measures
Primary Outcomes (1)
Number of patients with erector spinae muscle stimulation via stimulating catheter
Successful erector spinae plane needle and catheter insertion means that the needle/catheter is deep to the myofascia of the erector spinae muscle complex and superficial to the intertransverse ligaments / transverse process. Thus, any stimulation of the catheter after its placement in the erector spinae muscle complex seen under ultrasound or perceived by the patient will be documented as catheter placement failure. No visualized or perceived stimulation of the erector spinae muscle complex will be documented as catheter placement success.
Immediately after catheter placement (up to 5 minutes to assess)
Secondary Outcomes (12)
Time to perform erector spinae plane catheter
During catheter placement (up to 20 minutes)
Worst pain score ratings in the postanesthesia care unit (PACU)
as soon as patient can respond in PACU (up to 1 hour)
Highest and lowest vertebral level of sensory change after local anesthetic bolus
preoperatively, 30 minutes after local anesthetic bolus
Incidence of brachial plexus or intercostal stimulation via stimulating catheter before local anesthetic bolus
preoperatively, prior to local anesthetic bolus (up to 5 minutes)
Incidence of brachial plexus or intercostal stimulation via stimulating catheter after local anesthetic bolus
preoperatively, 30 minutes after local anesthetic bolus
- +7 more secondary outcomes
Study Arms (2)
Ultrasound Guidance Only
ACTIVE COMPARATORElectrical stimulation and Ultrasound Guidance
EXPERIMENTALInterventions
Electrical stimulation will be used to confirm needle and catheter placement within the interfascial plane between the erector spinae muscle and thoracic transverse process.
Ultrasound guidance will be used to visualize needle and catheter placement within the interfascial plane between the erector spinae muscle and thoracic transverse process.
