New nerve block aims to slash opioid use after shoulder surgery
NCT ID NCT06143306
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a pectoserratus nerve block to the standard interscalene block can better control pain and reduce opioid use after total shoulder replacement. About 110 adults aged 18 to 85 having shoulder replacement will be randomly assigned to receive either a numbing medicine or a placebo (salt water) in the extra block. The main goal is to see if the extra block lowers the highest pain score in the first 24 hours after surgery.

Inclusion Criteria: * Patients undergoing total shoulder arthroplasty or reverse total shoulder arthroplasty; * Patients aged 18-85 years old. Exclusion Criteria: * Patients who have an exclusion to regional anesthesia such as pre-existing nerve damage to their brachial plexus or infection at the site of injection. * Patients who have exclusion to interscalene blockade such as severe lung disease. * Non-English speakers will be excluded because pain scales are not validated in other languages and there is lack of standardization of pain reporting. * Pregnant patients * Patients who are currently using opioids and patients with a diagnosis of chronic pain will be excluded.
