Dexmedetomidine vs Fentanyl for preventing urine retention after lower limb surgery
Part of Bones, joints & muscles, Kidney & urinary clinical trials.
This trial compares two common medications, dexmedetomidine and fentanyl, when added to the numbing drug bupivacaine for spinal anesthesia. The goal is to see which one has a lower risk of causing temporary difficulty urinating after surgery on a leg or foot.
