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...

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...

Venous Thrombosis IV: Nursing Management

Venous Thrombosis IV: Nursing Management

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,...

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Coagulation

Coagulation

The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Area of Science:

Pediatric Cardiology
Biomedical Engineering
Hematology

Background:

Mechanical circulatory support (MCS) devices are critical for children with heart failure.
Optimizing anticoagulation in pediatric patients on MCS is essential to prevent thrombotic and bleeding complications.
Previous anticoagulation protocols had significant associated risks.

Purpose of the Study:

To compare the efficacy and safety of a new anticoagulation regimen versus a traditional one in children with pulsatile assist devices.
To evaluate the impact of different anticoagulation strategies on clinical outcomes, including bleeding, thromboembolism, and survival.

Main Methods:

Retrospective analysis of 40 children (Group A) on a former anticoagulation treatment and 32 children (Group B) on a new regimen.
Comparison of complication rates (bleeding, cerebral hemorrhage, thromboembolism, stroke) and re-exploration rates.
Assessment of device support duration and long-term survival.

Main Results:

Group B showed lower incidences of bleeding complications (38% vs 47.5%), chest re-exploration (25% vs 35%), and strokes (6% vs 15%) compared to Group A.
Thromboembolic events were similar between groups (22% vs 23%).
Mean support time was longer in Group B (57 days vs 19 days), with significantly higher long-term survival (78% vs 33%, p=0.003).

Conclusions:

The new anticoagulation regimen in pediatric patients on pulsatile assist devices is associated with reduced complications and improved long-term survival.
Despite improvements, thrombogenicity remains a significant challenge, necessitating further research and treatment optimization.
This study highlights the potential for enhanced anticoagulation strategies to improve outcomes in pediatric mechanical circulatory support.
