Blood Transfusion and Agglutination02:45

Blood Transfusion and Agglutination

12.0K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Structure and Function of Platelets

2.2K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Blood Transfusion

Blood transfusion is a critical medical procedure that saves lives and treats various medical conditions. It involves transferring blood from a donor to a recipient. This process requires a thorough understanding of the ABO blood group system and its associated antigens and antibodies.
Blood Transfusion Overview
A blood transfusion is a medical procedure used to replace blood lost due to injury, surgery, or to treat conditions such as anemia or cancer. During a transfusion, donor blood is...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Disorders of Hemostasis01:24

Disorders of Hemostasis

1.4K
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.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

773
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Area of Science:

  • Transfusion Medicine
  • Hematology
  • Biotechnology

Background:

  • Platelet transfusion supply is a logistical challenge due to storage requirements (22°C) and short shelf-life (<7 days).
  • Increasing demand for platelets, driven by demographic changes and hematology patient needs, exacerbates supply issues.
  • Current platelet products may not be optimal for achieving immediate hemostasis in bleeding patients.

Purpose of the Study:

  • To review the challenges in platelet supply and transfusion.
  • To explore emerging data on platelet efficacy in bleeding patients.
  • To highlight the need for improved platelet products and assessment methods.

Main Methods:

  • Literature review of current platelet physiology, storage, and transfusion practices.
  • Analysis of emerging research on alternative platelet preparations and storage.
  • Discussion of the need for better bleeding risk assessment and platelet efficacy measures.

Main Results:

  • Platelet storage at 22°C and short shelf-life (<7 days) create supply chain difficulties.
  • Existing research focuses on optimal dose and trigger for transfusion, primarily in hematology patients.
  • Alternative platelet products and improved efficacy assessment tools are under development.

Conclusions:

  • Current platelet transfusion practices face significant logistical and physiological challenges.
  • There is a growing need for optimized platelet products to enhance hemostasis in bleeding patients.
  • Further research into alternative preparations and efficacy assessment is crucial for improving patient outcomes.
