  • Study Participants

This study compares intra-articular lidocaine to procedural sedation for the reduction of anterior shoulder dislocations in the emergency department.
This will be a single center, prospective, open-label, randomized controlled trial on a convenience sample of patients presenting to the ED with anterior shoulder dislocations. This study will enroll all patients between the ages of 18 and 70 who meet all of the inclusion criteria and do not meet any of the exclusion criteria, who present to the ED with an anterior shoulder dislocation as determined by the ED physician. Written, informed consent will be obtained from each patient. After enrollment, each patient will be randomized either to IV sedation (with the provider's choice of propofol or etomidate) or intra-articular lidocaine. Randomization will be done before the initiation of data collection, and will be done with a random number generator. Patients who are randomized to the intra-articular group will receive 20 mL of 1% lidocaine injected into the glenohumeral joint using a lateral approach. Treating clinicians will be instructed to wait 10 minutes after injection before attempting reduction. The primary outcome measure will be the difference in emergency department length of stay between the procedural sedation and intra-articular lidocaine groups.

Drug Intra-articular Lidocaine

20 mL of 1% Lidocaine will be injected into the joint of the dislocated shoulder. Afterwards, the physician will attempt to reduce the shoulder using a technique of his or her choice.

Drug Procedural Sedation with etomidate or propofol [etomidate (amidate), propofol (diprivan)]

Procedural sedation using etomidate or propofol (physician's choice) will be performed. The dose of the drugs will also be left the treating physician. The physician will then attempt to reduce the shoulder using a technique of his or her choice.

Intra-articular Lidocaine Experimental

20 mL of 1% lidocaine injected into the joint of the dislocated shoulder

Procedural Sedation Active Comparator

Intravenous etomidate or propofol
