Reduction of acute anterior shoulder dislocations: comparing intraarticular lignocaine with intravenous anesthesia.
Anterior shoulder dislocation is the most common dislocation in the body. Various methods of anesthesia are available for reduction. The objective of this study was to compare the application of intra-articular anesthesia with intravenous anesthesia for reduction of acute anterior shoulder dislocation. This study was conducted at Kathmandu Medical College Teaching Hospital (KMCTH) and Kathmandu Hospital and comprised of patients coming with anterior dislocation of shoulder from July 2001 to June 2005. Forty-five patients aged 17-55 years with no associated fractures of adjoining bones were included in the study. In twenty-three patients, reduction was done using intra-articular anesthesia and in 22 patients intravenous anesthesia was given. In five patients (three in intra-articular group and two in intravenous group) the reduction technique had to be changed to the Hippocratic method. In these three patients intravenous anesthesia had to be given after intra-articular anesthesia failed to relieve pain and spasm. In the intravenous group two patients had to be admitted overnight while in the intra-articular group none had to be admitted to the hospital. However, in the intra-articular group the average time taken from injection to reduction was significantly longer (<.001). The use of intra-articular lignocaine for reduction of shoulder dislocation is safe and effective especially when patients present early. In patients presenting late (more than 5 hours) intravenous anesthesia should be primarily considered as the method for shoulder reduction.
