Summary
This review covers pharmacological strategies for preventing venous thromboembolism (VTE) after surgery. Risk assessment guides prophylaxis choices, with newer oral anticoagulants emerging for orthopedic procedures.
Area of Science:
- Pharmacology
- Vascular Surgery
- Thrombosis Prevention
Background:
- Venous thromboembolism (VTE) is a significant risk following surgery.
- Current antithrombotic drug use for VTE prevention is evidence-based.
- Surgical type and patient factors influence VTE risk.
Purpose of the Study:
- To review current pharmacological thromboprophylaxis strategies.
- To outline risk stratification for VTE post-surgery.
- To discuss evolving anticoagulant options.
Main Methods:
- Review of current scientific evidence and clinical guidelines.
- Analysis of risk factors influencing VTE development.
- Discussion of pharmacological agents and their indications.
Main Results:
- Minor surgery: early mobilization suffices.
- Major general surgery: low molecular weight heparin (LMWH), unfractionated heparin, or fondaparinux recommended.
- Major orthopedic surgery: LMWH, fondaparinux, vitamin K antagonists, or new oral anticoagulants (rivaroxaban, dabigatran) are standard.
Conclusions:
- Tailored thromboprophylaxis is crucial based on surgical and patient risk.
- New oral anticoagulants offer alternatives for orthopedic VTE prevention.
- Mechanical prophylaxis and anticoagulation should be combined in high-risk scenarios.

01:29Venous 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...
01:30Venous 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,...
01:27Pulmonary Embolism III: Nursing Management
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...
01:23Peripheral Artery Disease V: Postoperative Nursing Management
During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:29Pulmonary 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...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
