概括
低分子量肝素 (LMWH) 在初始静脉血栓栓塞 (VTE) 治疗中越来越喜欢低分子量肝素 (UFH),因为其结果更好,并发症更少. 在门诊治疗中,LMWH提供了优势,并且在肝素诱导的血小板缩和骨质疏松症方面似乎更安全.

Venous Thrombosis I: Introduction
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...
Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
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 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...
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,...
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...
Pulmonary 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...
