Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

16.2K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Venous Thrombosis I: Introduction

762
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...

Disorders of Hemostasis01:24

Disorders of Hemostasis

2.8K
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Coagulation01:09

Coagulation

12.4K
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...

Coagulation01:06

Coagulation

1.8K
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

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...

Area of Science:

  • Hematology
  • Internal Medicine
  • Critical Care Medicine

Background:

  • Disseminated intravascular coagulation (DIC) is a complex systemic disorder affecting coagulation.
  • It involves simultaneous pro-coagulant and fibrinolytic activation, leading to consumption coagulopathy.
  • DIC can result in organ dysfunction and mortality, with sepsis being a common trigger.

Purpose of the Study:

  • To review the pathophysiology, diagnosis, and management of Disseminated intravascular coagulation (DIC).
  • To highlight the importance of identifying underlying causes and utilizing diagnostic scoring systems.
  • To discuss current treatment strategies and their efficacy.

Main Methods:

  • Comprehensive literature review including textbook and Medline (PubMed) searches.
  • Keywords: DIC, thrombosis, fibrin degradation products, anti-thrombin, tissue factor.
  • Focus on evidence-based reviews and research from the past 25 years.

Main Results:

  • Diagnosis requires a causative factor and supportive laboratory tests (coagulation profile, clotting factors).
  • Effective scoring systems correlate with mortality risk.
  • Treatment focuses on the underlying disorder; low molecular weight heparin has specific indications, while others have doubtful value.

Conclusions:

  • Early diagnosis and prompt treatment of DIC, supported by laboratory findings, are essential.
  • Addressing the underlying systemic disorder is the primary therapeutic goal.
  • Effective management can significantly reduce morbidity and mortality associated with DIC.
