Comparison of Interscalene Block With Local Anesthetic Infiltration for Short-Term Outcomes After Shoulder Arthroplasty: A Single-Center Retrospective Cohort Study
Description
The presentation delivered by Malik Ali, an orthopedic surgery resident at Dalhousie University, discusses a study entitled "Comparison of Interscalene Block with Local Anesthetic Infiltration for Short-Term Outcomes After Shoulder Arthroplasty--A Single-Center Retrospective Cohort Study". The research evaluates postoperative pain management strategies after shoulder surgeries, emphasizing the efficacy of interscalene brachial plexus blocks versus local anesthetic infiltration. Ali acknowledges his coauthors and declares no conflicts of interest.
The study aims to address the challenges of postoperative pain in shoulder arthroplasty, noting the significant opioid use often resulting in adverse effects. The design involved a retrospective cohort analysis conducted at the Queen Elizabeth II Health Sciences Center, including patients aged over 18 who underwent various shoulder arthroplasties between 2016 and 2018, while excluding those on regular opioids or with incomplete data.
Key outcomes measured were total opioid morphine equivalents used and pain scores at various postoperative stages. The results indicated that patients receiving interscalene blocks had lower initial pain scores and reduced opioid requirements on the day of surgery, despite a higher prevalence of revision surgeries in that group, with no significant differences in hospital stay or emergency visits post-discharge.
Ali discusses statistical analyses and summarizes the findings with an emphasis on the benefits of interscalene blocks in managing pain effectively postoperatively, thereby potentially decreasing immediate opioid needs. He concludes by inviting questions from the audience.
