Ultrasound-Guided Peripheral Nerve Blocks for Shoulder Dislocation in the Emergency Department: A Systemic Review
Conclusion: USG-PNBs performed by adequately trained EPs may be a reasonable first option for analgesia during closed reduction of dislocated shoulders in the ED, particularly in patients with cardiorespiratory comorbidities. Although USG-PNBs have lower overall success for reduction, they have lower complication rates compared with PSA. This systematic review can serve as a guide for designing larger prospective studies to compare the utility of USG-PNB, IAA, and PSA for shoulder dislocation management in the ED.
