However, the use of epidural catheters is associated with complications. The insertion of the catheter may be associated with intravascular or intrathecal placement, nerve root irritation, paresthesia, kinking, hematoma, or breakage during catheter removal.\n\nPatients and Methods: This was a prospective, randomized, double-blind clinical trial; carried out on 60 patients undergoing major orthopedic surgery under continuous epidural anesthesia. Patients were randomly allocated into two equal groups; group N, using Nylon catheter, and group P, using Polyurethane catheter.",[26,27,28,29,30],"Epidural; Anesthesia","Catheter Complications","Catheter Blockage","Catheter Dysfunction","Catheter Breakage",[32,33,34],"Epidural Anesthesia","Nylon (Polyamide) Epidural Catheter","Polyurethane Epidural Catheter","RECRUITING","2026-01-09",{"date":38,"type":39},"2026-01-12","ACTUAL",{"date":41,"type":39},"2025-07-01",{"date":43,"type":20},"2026-12-30",{"name":45,"class":46},"Damanhour Teaching Hospital","OTHER_GOV"]
