Context: Few reports have investigated the time course of fibrinogen (or fibrin) degradation product (FDP) levels for trauma patients in the subacute phase. Aims: This study aimed to investigate the time course of the FDP levels among patients with moderate and severe trauma in the subacute phase. Settings and Design: A retrospective medical chart review in a single hospital. Subjects and Methods: From September 2017 to March 2018, a medical chart review was retrospectively performed for all patients with trauma who were admitted to our department, and these patients were included as participants in the present study. We collected the data on each patient's sex, age, presence of head injury, mechanism of injury, Glasgow Coma Scale on arrival, systolic blood pressure, heart rate, type of injury (blunt versus penetrating), injury severity score, complication of infection, surgical procedure, duration of admission, survival rate, and FDP level from the 1st to 7th hospital day. The average level of FDP on each hospital day was compared with that on the previous day. Statistical Analysis Used: The statistical analyses were performed using a paired Student's t-test. P < 0.05 was considered to indicate a statistically significant difference. Results: From the 1st to 4th hospital day, the average level of FDP significantly diminished day by day. However, from the 5th hospital day, the average level significantly increased. This trend persisted even after excluding the complications of infection and surgical procedures performed between the 2nd and 7th hospital day. Conclusions: Among trauma patients, the average level of FDP significantly diminished day by day from the admission to the 4th hospital day; however, from the 5th hospital day, the average level significantly increased. Further studies are needed to determine the time course of FDP or D-dimer levels in the long term and when FDP levels return to normal limits.
