• Bleeding: This is the most significant risk associated with thrombolytic therapy. Patients may experience spontaneous bleeding, which can manifest as:
• Hematuria (blood in urine)
• Melena (black, tarry stools)
• Ecchymosis (bruising)
• Nosebleeds
• Hypotension: A drop in blood pressure may occur due to excessive bleeding.
• Allergic Reactions: Some patients may experience allergic reactions, including rash, itching, or anaphylaxis.
• Neurological Symptoms: In cases where thrombolytics are used for stroke, symptoms may include confusion, weakness, or changes in consciousness.

Diagnosis

Diagnosis of accidental poisoning by thrombolytic drugs typically involves:

• Patient History: Gathering information about the circumstances of the exposure, including the specific drug, dosage, and timing.
• Physical Examination: Assessing for signs of bleeding or other adverse effects.
• Laboratory Tests: Blood tests may be conducted to evaluate coagulation parameters, such as prothrombin time (PT) and activated partial thromboplastin time (aPTT), to assess the extent of anticoagulation.

Treatment

Management of accidental thrombolytic drug poisoning focuses on supportive care and may include:

• Discontinuation of the Drug: Immediate cessation of the thrombolytic agent.
• Supportive Measures: Monitoring vital signs and providing fluids or blood products as needed to manage bleeding.
• Reversal Agents: In some cases, specific reversal agents may be used, although options are limited for thrombolytics compared to anticoagulants.

Coding and Documentation

When documenting accidental poisoning by thrombolytic drugs, it is essential to specify the circumstances of the poisoning, including whether it was unintentional. The code T45.611 is used for cases where the poisoning is accidental, distinguishing it from intentional overdoses or adverse effects.
