Resumen
El embarazo causa cambios significativos en el recuento de células sanguíneas. El recuento de plaquetas disminuye, mientras que el recuento total de leucocitos, particularmente los neutrófilos, aumenta sustancialmente durante la gestación.
Área de la Ciencia:
- Hematología Hematología.
- Obstetricia y obstetricia.
- Inmunología Inmunología.
Sus antecedentes:
- El embarazo implica importantes adaptaciones fisiológicas.
- Los cambios en el recuento de células sanguíneas durante el embarazo son comunes, pero requieren una caracterización detallada.
Objetivo del estudio:
- Para rastrear longitudinalmente los cambios en el recuento de plaquetas y leucocitos durante el embarazo.
- Para identificar subconjuntos específicos de leucocitos afectados durante la gestación.
Principales métodos:
- Se utilizó una metodología automatizada para el conteo de células sanguíneas.
- Veintitrés mujeres fueron estudiadas a lo largo del embarazo y postparto.
Principales resultados:
- El recuento de plaquetas mostró una disminución monótona consistente con el aumento del volumen sanguíneo.
- El recuento total de leucocitos aumentó, principalmente debido a un aumento en los neutrófilos.
- Los recuentos absolutos de neutrófilos fueron casi el doble durante la gestación en comparación con el posparto.
Conclusiones:
- El embarazo induce cambios claros en los parámetros hematológicos.
- Los recuentos de neutrófilos aumentan significativamente durante el embarazo, volviendo a la línea de base después del parto.

Blood Transfusion and Agglutination
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...

Composition of Blood
The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...

Overview of Hematopoiesis
Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...

Structure and Function of Platelets
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 platelets, with...

Rh Blood Group
The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
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...
