Randomized Controlled TrialReduced Hemidiaphragmatic Paresis With a "Corner Pocket" Technique for Supraclavicular Brachial Plexus Block: Single-Center, Observer-Blinded, Randomized Controlled Trial.
Hemidiaphragmatic paresis is common after supraclavicular brachial plexus block (SCBPB). In this randomized trial, we compared the incidence of hemidiaphragmatic paresis in patients who had local anesthetic injected primarily in the corner pocket (defined as the intersection of the first rib and subclavian artery) during SCBPB with that of patients who underwent injection primarily inside the neural cluster. ⋯ This study was registered at Clinical Trial Registry of Korea, identifier KCT0001769.

Observational StudyAcute Pain Is Associated With Chronic Opioid Use After Total Knee Arthroplasty.
Pain scores are routinely reported in clinical practice, and we wanted to examine whether this routinely measured, patient-reported variable provides prognostic information, especially with regard to chronic opioid use, after taking preoperative and perioperative variables into account in a preoperative opioid user population. ⋯ Acute pain predicts chronic opioid use. Prospective studies of efforts to reduce acute pain, in terms of long-term effects, are needed.

Randomized Controlled TrialSelective Suprascapular and Axillary Nerve Block Versus Interscalene Plexus Block for Pain Control After Arthroscopic Shoulder Surgery: A Noninferiority Randomized Parallel-Controlled Clinical Trial.
This randomized trial aimed to assess if a combined suprascapular-axillary nerve block (SSB) is noninferior (margin = 1.3 on a 0- to 10-point scale) to interscalene block (ISB) in treating pain after arthroscopic shoulder surgery. Secondary end points included opioid consumption, dyspnea, discomfort associated with muscle weakness, and patient satisfaction. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02415088.
