Abstract:
OBJECTIVE: To analyze the experience of diagnosis and treatment of a case of brodifacoum poisoning. METHODS: The clinical data of a case of unexplained brodifacoum poisoning was retrospectively analyzed. RESULTS: The patient went to the doctor for unexplained bleeding. The bleeding symptoms included nasal o blood ozing, blood in saliva and skin ecchymosis. Blood anticoagulative rodenticide test showed positive with brodifacoum. The results of coagulative function tests showed that the indexes of partial prothrombin time, prothrombin time and fibrinogen were increased. The patient was diagnosed as brodifacoum poisoning based on the clinical symptoms and laboratory test results. The combined use of 40 mg/d of vitamin K_1 and frozen plasma improved the clotting time and quickly alleviated the bleeding symptoms of the patient. However, the patient′s bleeding symptoms recurred when vitamin K_1 was discontinued. The patient was hospitalized for 62 days and then discharged. With follow-up one month after discharge, the patient showed no bleeding symptoms, but brodifacoum could still be detected in the blood. CONCLUSION: The symptoms of brodifacoum poisoning may relapse and the treatment course is long. Vitamin K_1 could be used as the first-choice medicine for the treatment of brodifacoum poisoning, but its usage needs to be optimized.
