Why the study?
Potent opioids in patient-controlled intravenous analgesia have undesirable side effects, prompting the evaluation of ultrasound-guided interscalene block versus patient-controlled intravenous analgesia for postoperative pain relief following shoulder surgery.
Does ultrasound-guided interscalene block reduce postoperative narcotic consumption and improve pain control compared to patient-controlled intravenous analgesia in patients undergoing shoulder surgery?
Does ultrasound-guided interscalene block reduce postoperative narcotic consumption and improve pain control compared to patient-controlled intravenous analgesia in patients undergoing shoulder surgery?
Ultrasound-guided interscalene block is more effective than patient-controlled intravenous analgesia for reducing narcotic consumption and controlling pain after shoulder surgery.
No takes yet. Share an insight, caveat, or question.
May support ultrasound-guided ISB over PCIVA for shoulder surgery analgesia; leaves open need for randomized trials.
