In the United States, 24 shoulder dislocations are reported per year per 100,000 people, or nearly 80,000 dislocations. It most often occurs after a violent trauma. Young adults are most often affected; it is common in epileptics. Reduction of the dislocation is a trauma emergency All types of anesthesia can be used for shoulder dislocation reduction. The objective of this study was to evaluate the efficacy and safety of the interscalene block for shoulder dislocation reduction.Methods Prospective descriptive study conducted in Batna University Hospital during the 2023/2024. Inclusion criteria were adult patients admitted for shoulder dislocation. The interscalene block was performed under ultrasound guidance. Demographic data, block data (performance time, onset time, LA), success, and complications were recorded.Results Twenty patients were included during the study period. The mean age of our patients was 40 years (range, 19–83). Sex: 18 men/2 women. All patients fasted for more than 6 hours. All blocks were performed using the lateral in plane approach, except for one patient. For the first 6 cases, we used a mixture of lidocaine and bupivacaine, with a volume between 5 and 10 ml For the following 14 patients, we used 2% lidocaine alone with a volume between 5 and 17 ml. For the injection site: We injected 8 times around C5, 10 times between C5 and C6, and 2 times (7 ml) above C5. The block took 1–5 minutes to perform and the block onset time was 1–2 minutes. Only one complication was reported: paresthesias during a two-injection block. Success was 100% with a single attempt in 18 cases.Conclusions The interscalene block is an effective and safe technique for reducing shoulder dislocation; ultrasound guidance allows for reduced doses and a reduced risk of complications",
