Addition of a Pectoserratus Block to Interscalene Block in Patients Undergoing Total Shoulder Replacement

Recruiting now · Phase 4

Conditions studied: Total Shoulder Arthroplasty

In brief

The use of ISB in patients undergoing total shoulder arthroplasty (TSA) is the gold standard and results in significantly reduced pain scores and opioid use. However, patients still have pain and the majority require opioids postoperatively as the interscalene block (ISB) doesn't cover all of the dermatomes impacted during TSA. A pectoserratus block typically provides coverage to additional dermatomes that are impacted during TSA. Currently ISB is performed for every patient and perform a pectoserratus block to a portion of our patients undergoing TSA. The purpose of the study is to determine if the addition of the pectoserratus block to the ISB will results in improvement in pain control and decrease in opioid use, among patients undergoing TSA. This is a randomized prospective controlled trial. All patients undergoing total shoulder arthroplasty or reverse total shoulder arthroplasty aged 18-85 will be considered eligible for the study. Participants will be randomized to one of 2 treatment groups. Group 1 will receive an ultrasound guided pectoserratus block with 25 mL of 0.25% bupivacaine. Group 2 will be the control and receive an ultrasound guided pectoserratus block with 25 mL of saline. The drug will be administered by the anesthesiologist in-charge of the participant's care or an anesthesiologist who is a part of the study team.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients undergoing total shoulder arthroplasty or reverse total shoulder arthroplasty;
• Patients aged 18-85 years old.

You may not qualify if…

• 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.
