Rate of occurrence of respiratory complications in patients who undergo shoulder arthroplasty with a continuous interscalene brachial plexus block and associated risk factors
Authors' conclusion
Patient-related factors that can be measured preoperatively are associated with increased likelihood of respiratory complications after elective shoulder arthroplasty with CISB.
