Randomized Controlled Trial
Comparison of the analgesic efficacy between arthroscopically placed continuous suprascapular nerve block and ultrasound-guided continuous superior trunk block: a double-blinded randomized controlled trial.
Single-shot suprascapular nerve block and superior trunk block have been reported to provide a noninferior analgesic effect after shoulder surgery with a lesser incidence of hemidiaphragmatic paresis compared with interscalene brachial plexus block. This study hypothesized that continuous suprascapular nerve block provides noninferior analgesia with minimal effects on diaphragmatic movement compared with continuous superior trunk block in patients undergoing arthroscopic shoulder surgery. ⋯ Continuous suprascapular nerve block provides statistically inferior analgesia compared to the continuous superior trunk block; however, the continuous suprascapular nerve block had a minimal effect on the phrenic nerve function.

PROSPECT methodology for developing procedure-specific pain management recommendations: an update.
The procedure-specific postoperative pain management (PROSPECT) working group develops evidence-based pain management recommendations. PROSPECT methodology is unique and rigorous. However, several limitations were recognised that needed to be addressed, and several new factors were identified that improved PROSPECT methodology. ⋯ Future projects will use the Cochrane Collaboration risk of bias tool for quality of reporting of methodology and results. A modified Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach will be used for grading of level of evidence and strength of recommendations. Finally, the updated PROSPECT methodology addresses several other limitations and implements new factors that all add rigour and transparency to developing procedure-specific pain management recommendations.

Rate of occurrence of respiratory complications in patients who undergo shoulder arthroplasty with a continuous interscalene brachial plexus block and associated risk factors.
Continuous interscalene nerve block techniques are an effective form of targeted non-opioid postoperative analgesia for shoulder arthroplasty patients. One of the limiting risks, however, is potential phrenic nerve blockade with resulting hemidiaphragmatic paresis and respiratory compromise. While studies have focused on block-related technical aspects to limit the incidence of phrenic nerve palsy, little is known about other factors associated with increased risk of clinical respiratory complications in this population. ⋯ Patient-related factors that can be measured preoperatively are associated with increased likelihood of respiratory complications after elective shoulder arthroplasty with CISB.
