Insights

Current guidelines suggest avoiding blood transfusions for stable children with iron deficiency anemia. This study found hemoglobin levels effectively predict the need for red blood cell transfusions in anemic pediatric patients.

Area of Science:

  • Pediatric Hematology
  • Anemia Management
  • Transfusion Medicine

Background:

  • Iron deficiency anemia is common in young children.
  • Current guidelines recommend against transfusions in stable anemic children.
  • Predicting transfusion needs in this population remains a clinical challenge.

Purpose of the Study:

  • To evaluate the predictive value of hemoglobin levels for red blood cell transfusion in hospitalized children with iron deficiency anemia.
  • To identify a potential hemoglobin threshold for transfusion decisions.

Main Methods:

  • Observational study design.
  • Inclusion of 125 children aged 6-36 months with iron deficiency anemia.
  • Analysis of hemoglobin levels as a predictor for red blood cell transfusion.

Main Results:

  • Hemoglobin level demonstrated strong predictive capability for red blood cell transfusion (AUC 0.8862).
  • A hemoglobin threshold of 39 g/L showed 92% sensitivity and 72% specificity for predicting transfusion necessity.

Conclusions:

  • Hemoglobin level is a reliable predictor of red blood cell transfusion in pediatric iron deficiency anemia.
  • A hemoglobin level of 39 g/L may serve as a useful clinical marker for transfusion decisions in this cohort.
  • Findings may inform clinical practice regarding transfusion management in anemic children.

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...

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...

Oxygen Transport in the Blood

Hemoglobin (Hb) is a crucial molecule in the human body, consisting of four polypeptide chains, each bound to an iron-containing heme group. This unique structure enables hemoglobin to bind to oxygen, with each molecule capable of combining with four molecules of oxygen, leading to rapid and reversible oxygen loading. When fully loaded with oxygen, it is called oxyhemoglobin, while hemoglobin that has released oxygen is called reduced hemoglobin or deoxyhemoglobin. As hemoglobin binds oxygen,...

Erythropoiesis01:14

Erythropoiesis

Red blood cells  (RBCs) transport oxygen to all body tissues. These cells survive only for 120 days and then need to be replenished. Erythropoiesis is the process of RBC production. In healthy individuals, erythropoiesis ensures all tissues are amply supplied with oxygen. In addition, blood loss due to injury leads to a drop in the physiological oxygen level that will cause erythropoiesis. Any defect in erythropoiesis leads to several physiological disorders, including thalassemia, anemia,...

Hemoglobin01:24

Hemoglobin

Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
