Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

277
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Acute Coronary Syndrome III: Diagnostic Studies

197
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Summary

This case study suggests a link between paraquat poisoning and elevated D-dimer levels. Further research is needed to confirm if D-dimer elevation is a direct indicator of paraquat toxicity.

Area of Science:

  • Toxicology
  • Internal Medicine
  • Emergency Medicine

Background:

  • Paraquat is a highly toxic herbicide causing severe poisoning.
  • Accidental paraquat ingestion can lead to significant oral and respiratory complications.
  • Elevated D-dimer levels typically indicate a risk of blood clots, such as pulmonary embolism.

Purpose of the Study:

  • To report a case of accidental paraquat ingestion.
  • To investigate the cause of elevated D-dimer levels in a paraquat poisoning patient.
  • To explore the potential association between paraquat poisoning and D-dimer level elevation.

Main Methods:

  • A case report of a 74-year-old female patient with accidental paraquat ingestion.
  • Clinical observation and laboratory tests, including D-dimer levels.
  • Diagnostic workup to rule out pulmonary embolism.

Main Results:

  • The patient presented with dysphagia and oral burns after paraquat ingestion.
  • A significant increase in blood D-dimer levels was observed.
  • Pulmonary embolism and other complications were excluded through further evaluation.

Conclusions:

  • Elevated D-dimer levels may be associated with paraquat poisoning itself.
  • This finding warrants further investigation into the pathophysiological mechanisms.
  • Paraquat poisoning requires careful monitoring for various complications, including potential thrombotic markers.
