Abstract
Patients who have undergone surgery must be closely monitored for the potential development of Fat Embolism Syndrome (FES).This case report present a 45-year-old patient who had implant removal a year after lower limb fracture repair. The patient was stable following surgery at first, but on the second day, soon after ciprofloxacin was administered, the patient experienced a high fever, chest pain, shivering, and sweating. He was treated with heparin and an acute coronary syndrome protocol after the initial treatment for a suspected medication reaction proved ineffective. The patient gradually stabilized after vomiting a yellow, greasy material. This case emphasizes the importance of being vigilant in identifying FES in postoperative patients, since prompt identification and supportive care are essential for positive results.
