title: Reduction of traumatic, primary anterior shoulder dislocations with local anesthesia.
abstract: This study evaluates the use of local anesthesia in the reduction of acute shoulder dislocations. Patients with a primary traumatic dislocation of the shoulder were randomly assigned to receive either local anesthesia or intravenous anesthesia. The patients were observed for any complication during and after the procedure, and the methods used were evaluated with a visual analog scale. In the period from November 1991 to September 1993, 81 patients were admitted to our departments, and 68 patients were included in the study. Average age was 48 years (range 15 to 79 years); 29 men and 39 women were studied. Thirty-five patients were randomly assigned to receive intravenous anesthesia; 33 had a successful reduction, and two had a failed reduction. Thirty-three patients received local anesthesia; 32 had a successful reduction, and one had a failed reduction. Ten patients treated with the intravenous method had respiratory depression, and six required an antidote. No systemic or local side effects and no neurovasculor injuries were recorded. We did not observe any superficial or deep infection in the local anesthetic group. No statistical difference was found between the average visual analog value scale in the two groups. Local anesthesia to reduce acute primary anterior dislocation of the shoulder is a simple and safe method.
