Insights
For premature infants with anemia, a one-week interval for red blood cell (RBC) transfusions significantly boosts hemoglobin (Hb) levels more than longer intervals. This finding optimizes transfusion strategies for neonates.
Area of Science:
- Neonatal Medicine
- Hematology
- Pediatric Transfusion Medicine
Background:
- Premature infants often require blood transfusions.
- Limited research exists on how the timing of red blood cell (RBC) transfusions impacts hemoglobin (Hb) levels in neonates.
- Understanding optimal transfusion intervals is crucial for managing anemia in premature infants.
Purpose of the Study:
- To investigate the effect of administering the same RBC package at varying time intervals on Hb concentration in premature infants.
- To determine if different transfusion intervals influence the increase in Hb levels.
Main Methods:
- A study involving 196 anemic premature infants receiving identical RBC transfusion packages at two distinct intervals.
- Hb levels were measured before and within 24 hours post-transfusion for both instances.
- Data were analyzed across four groups based on the time elapsed between transfusions.
Main Results:
- Significant pre- and post-transfusion Hb level increases were observed with the same RBC package.
- Hb increments varied by group: Group I (1-week interval) showed 43.00 g/L, Group II 34.50 g/L, Group III 32.00 g/L, and Group IV 32.50 g/L.
- Group I demonstrated a statistically significant higher Hb increment compared to Groups II, III, and IV (P<0.05).
Conclusions:
- Infusing the same RBC package at different intervals significantly elevates Hb levels in premature infants with anemia.
- A one-week interval between transfusions yields the most substantial increase in Hb concentration.
- This suggests that shorter, regular transfusion intervals may be more effective for managing neonatal anemia.
Purpose:
Blood transfusions are performed in small amounts in premature infants. Few studies have focused on the effect of the same red blood cell (RBC) package at different intervals on increasing hemoglobin(Hb) concentration. We aimed to determine the effect of infusion of the same RBC package at different time intervals on Hb levels in premature infants.
Patients And Methods:
Data were collected about premature infants who received the same package of RBC transfusion at two different intervals. Venous blood Hb levels before and within 24 hours after transfusion were measured for the first and second transfusions. Overall, 196 premature infants with anemia were included in the study. The data were categorized into four groups (Group I, Group II, Group III and Group IV) based on the varying intervals between transfusions of the same red blood cells.
Results:
Hb levels of the first and second transfusions with the same RBC package showed a significant difference pre and posttransfusion. Hb increments varied among groups: Group I (43.00 g/L), Group II (34.50 g/L), Group III (32.00 g/L), and Group IV (32.50 g/L), with Group I demonstrating a significant difference compared to Groups II, III, and IV (P<0.05), while no differences were noted among the latter groups.
Conclusion:
In premature infants with anemia, hemoglobin levels significantly increased after infusion of the same RBC package at different intervals. An interval of 1 week had the most significant effect.
What Is New:
There are differences in the effect of infusion of the same RBC at different time intervals on hemoglobin levels in premature infants. An interval of 1 week had the most significant effect.

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...

Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
