We determined the effect of cord blood collection before placental expulsion on postpartum maternal blood loss in a retrospective study between a group of cord blood donors and a group of non-donors. The study was conducted in a university hospital blood bank and obstetric services and included Spanish women entered in a European study project (EUPHRATES) and who had consented to donate cord blood for public banking purposes. We measured blood volume lost during delivery by a bag collection method, as well as the need for transfusion and postpartum anemia symptoms. Deliveries at which cord blood was collected presented a significant increase in blood loss (321 ± 273 vs. 255 ± 237 ml, p=0.02). Instrumental deliveries were associated with higher postpartum blood loss than spontaneous deliveries. Cord blood collection can increase intrapartum blood loss, especially at instrumental deliveries. Additional staff who handle the collection are required to allow the leading clinician to focus on maternal care.

The Rhesus (Rh) antigen is crucial in determining blood groups and ensuring compatibility during blood transfusions.
Blood Transfusion and Agglutination02:45

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...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

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...
