Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care01:29

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

31
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...

Pulmonary Embolism III: Nursing Management

27
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Pulmonary Embolism I: Introduction

33
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Venous Thrombosis III: Interprofessional Care

18
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Venous Thrombosis IV: Nursing Management

19
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

247
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Area of Science:

  • Pulmonary Medicine
  • Radiology
  • Cardiovascular Medicine

Context:

  • Computed tomodensitometry (CT) has increased the detection of subsegmental pulmonary embolism (PE).
  • The clinical significance and optimal management of subsegmental PE remain subjects of ongoing debate.
  • Uncertainty exists regarding the necessity of therapeutic anticoagulation for these smaller emboli.

Purpose:

  • To review the current literature on the diagnosis and management of subsegmental PE.
  • To critically evaluate the evidence supporting therapeutic anticoagulation in subsegmental PE.
  • To propose a practical, evidence-based approach for guiding anticoagulation decisions.

Summary:

  • Subsegmental PE detection is rising due to advanced imaging like CT.
  • Clinical implications and treatment indications, particularly anticoagulation, are not well-defined.
  • This article synthesizes existing research to inform management strategies.

Impact:

  • Provides clarity on the clinical implications of subsegmental PE.
  • Offers a pragmatic framework for clinicians managing patients with subsegmental PE.
  • Aims to optimize treatment decisions, potentially reducing unnecessary anticoagulation and associated risks.
