Venous Thrombosis III: Interprofessional Care

Venous Thrombosis III: Interprofessional Care

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...

Hemodialysis I: Introduction

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

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...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Endocarditis IV: Nursing Management

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Summary

This summary is machine-generated.

Venous thromboembolism (VTE) can occur after extracorporeal membrane oxygenation (ECMO). A new method allows for safe IVC filter placement during ECMO using intravascular ultrasound (IVUS) to prevent VTE.

Area of Science:

Cardiovascular Medicine
Medical Devices
Interventional Cardiology

Background:

Extracorporeal membrane oxygenation (ECMO) is a life-support technology used for severe respiratory or cardiac failure.
Venous thromboembolism (VTE), including inferior vena cava (IVC) thrombi and pulmonary embolism, is a significant complication post-ECMO.
VTE risk is associated with indwelling venous cannulas and potential anticoagulation challenges due to bleeding.

Observation:

A simple, effective technique for guidewire exchange of femoral venous ECMO cannulas was developed.
This exchange facilitates the placement of a working catheter for intravascular ultrasound (IVUS) guided IVC filter insertion.
The methodology ensures continued ECMO support during filter placement.

Findings:

The described technique enables secure IVC filter placement in patients requiring ECMO.
Intravascular ultrasound (IVUS) provides real-time visualization for accurate filter deployment.
This approach addresses the challenge of VTE prevention in high-risk ECMO patients.

Implications:

This method offers a potential strategy to mitigate VTE complications in ECMO patients.
Improved VTE management may lead to better clinical outcomes and reduced mortality.
The technique could be integrated into standard ECMO protocols for enhanced patient safety.
