The main focus of the study is to see which combination causes fewer problems with urination after surgery - a condition known as postoperative urinary retention (POUR). POUR can lead to discomfort, delayed recovery, and a need for catheterization. Dexmedetomidine is a newer drug that may help reduce this problem compared to fentanyl, which is more commonly used but may increase the risk of urinary retention. This trial will help determine which medication combination provides better pain relief while reducing urinary side effects. The study is being conducted as a randomized, double-blind trial at a hospital in Nepal and will include 190 adult patients.\n\n\\-",[29,30,31,32,33,34,35,36,37],"Spinal Anesthesia","Postoperative Complications","Dexmedetomidine","Fentanyl","Anesthesia, Spinal","Bupivacaine","POUR","Orthopedic Surgery","Urinary Retention Postoperative",[39,40,41,31,32,42],"Postoperative urinary retention","Spinal anesthesia","Intrathecal adjuvants","Perioperative complications","NOT_YET_RECRUITING","2025-08-09",{"date":46,"type":47},"2025-08-12","ACTUAL",{"date":49,"type":23},"2025-09-15",{"date":51,"type":23},"2026-11-25",{"name":53,"class":54},"Tribhuvan University Teaching Hospital, Institute Of Medicine.","OTHER"]
