Venous Thrombosis III: Interprofessional Care01:29

Venous Thrombosis III: Interprofessional Care

217
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

153
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,...

Pulmonary Embolism III: Nursing Management01:27

Pulmonary Embolism III: Nursing Management

239
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 II: Diagnostic Studies and Interprofessional Care

200
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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

219
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis I: Introduction

197
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Area of Science:

  • Internal Medicine
  • Cardiology
  • Critical Care Medicine

Background:

  • Venous thromboembolism (VTE) is a significant cause of mortality and increased healthcare costs in hospitalized medical patients.
  • Nearly half of VTE events occur during or after hospitalization, with pulmonary embolism contributing to 10% of inpatient deaths.
  • Despite evidence-based guidelines, VTE prophylaxis remains under-utilized due to concerns regarding patient and agent selection, and prophylaxis duration.

Purpose of the Study:

  • To review current evidence and reasoning for appropriate VTE prophylaxis selection in acutely medical ill patients.
  • To address ambiguity and concerns related to patient and prophylactic agent selection, and duration of prophylaxis.
  • To highlight a specific approach and recommendations for VTE prophylaxis.

Main Methods:

  • Review of current evidence and established risk assessment models for VTE and bleeding.
  • Analysis of factors influencing prophylaxis selection, including cost, availability, patient preference, compliance, and comorbidities.
  • Discussion of the extended VTE risk beyond hospital discharge.

Main Results:

  • Under-utilization of VTE prophylaxis persists despite established guidelines.
  • Risk assessment models aid in estimating VTE and bleeding risks in medical patients.
  • No current evidence supports extending VTE prophylaxis after hospital discharge.

Conclusions:

  • Appropriate VTE prophylaxis selection requires careful consideration of individual patient factors and risks.
  • Addressing concerns regarding patient and agent selection, and prophylaxis duration is crucial for improving VTE prevention.
  • This paper provides a framework and recommendations for optimizing VTE prophylaxis in acutely medical ill patients.
