Summary

This study looks at how well neostigmine reverses the muscle relaxant mivacurium during foot and ankle surgery. Researchers will test 120 adults to find the best time to give neostigmine so muscles recover quickly and safely. The goal is to improve recovery from anesthesia, not to cure or treat a disease.
