The present study aimed to investigate haemoglobin (Hb) changes before and after packed red blood cell (RBC) transfusion in burn patients. This study was a retrospective cross-sectional study that was conducted on burn patients in Velayat hospital in Rasht, Iran. The sampling method of this study was consecutive sampling. Data were collected using patient records, including age, gender, body mass index (BMI), total body surface area (TBSA) percentage, length of hospitalisation, Frequency of receiving packed RBCs, and Hb level before each packed RBC transfusion and 4 to 6 hours after transfusion. Paired t tests and analysis of variance (ANOVA) were used to compare the study variables. Pearson's correlation coefficient was used to investigate the relationship between Hb changes after the transfusion of packed RBCs and the study variables. A total of 110 burn patients participated in this study. The average Hb before and after transfusion was 8.07 (SD = 0.97) and 9.16 (SD = 1.01), respectively, which were significantly different (P = .0001). The results showed that there was a significant negative relationship between the variables of age (r = -0.188, P = .0001), BMI (r = -0.110, P = .035), and TBSA percentage (r = -0.122, P = .019) with changes in Hb after transfusion. Also, the duration of hospitalisation had a significant positive relationship with Hb changes after transfusion (r = 0.124, P = .017). In sum, Hb level compensation through packed RBC transfusion in elderly burn patients has more challenges. The number of changes in Hb level after receiving packed RBCs decreased with increasing TBSA, BMI, and age. Also, there was a positive correlation between the duration of hospitalisation and changes in Hb levels.

Oxygen Transport in the Blood01:27

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,...

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...

Blood Transfusion01:15

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...

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...

Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Bone Marrow Sampling and Transplants01:22

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...
