A patient received a 10-fold overdose of heparin due to a suspected pulmonary embolism, leading to fatal cerebral hemorrhage. This case highlights critical medication errors and challenges in medical expertise.

Area of Science:

  • Medical error analysis
  • Pharmacology
  • Clinical toxicology

Background:

  • Pulmonary embolism (PE) is a life-threatening condition requiring prompt anticoagulation.
  • Heparin is a common anticoagulant used in managing PE.
  • Accurate dosing is crucial to prevent adverse events.

Observation:

  • A 62-year-old male patient was treated for suspected pulmonary embolism.
  • The patient received 550,000 I.U. of heparin instead of the prescribed 55,000 I.U. within 24 hours.
  • This represents a tenfold overdose of the therapeutic dose.

Findings:

  • The patient died the following day due to cerebral hemorrhage.
  • Autopsy confirmed the cause of death was intracranial bleeding.
  • The overdose significantly increased the risk of bleeding complications.

Implications:

  • Highlights the critical importance of double-checking medication dosages, especially with high-risk drugs like heparin.
  • Underscores the potential for severe adverse events and fatalities resulting from medication errors.
  • Emphasizes the need for robust protocols and vigilance in clinical practice to prevent such errors and discusses challenges in medical expertise for such cases.
