Observational Study of Intra-Articular Lidocaine for Management of Shoulder-Dislocation at Sylvanus Olympio University Teaching Hospital, Togo - Abstract
Background: Intra-articular injection of lidocaine is a recognized anesthetic technique for closed reduction of Anterior Internal Shoulder Dislocation (AISD), which may be of particular benefit to patients in developing countries.
Methods: A prospective observational study was conducted of patients admitted to the Sylvanus Olympio University Teaching Hospital, Togo with a diagnosis of AISD between August 1 2010 and March 31 2011. Demographic and relevant clinical data, including patient satisfaction were collected.
Results: 60 patients with AISD were admitted during this period. There was a male predominance (75%), with median age of 33 years. The injury had occurred in the street in 35 cases. Sub-coracoid dislocation was demonstrated on X-ray in 42 cases. Intra-articular lidocaine 2% was administered and was effective 3 minutes after injection in most cases, with a success rate of 95%. 54 patients required less than 5ml lidocaine 2% in total. No immediate complications were reported, and patient satisfaction was high.
Conclusion: The use of intra-articular lidocaine is a useful technique for reduction of AISD, which should be considered in developing countries.
