Blood Transfusion01:15

Blood Transfusion

498
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

10.7K
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...

Summary

A liberal red-cell transfusion strategy did not improve neurologic outcomes for patients with aneurysmal subarachnoid hemorrhage and anemia compared to a restrictive strategy. Both approaches showed similar results in functional independence and quality of life at 12 months.

Area of Science:

  • Neurology
  • Critical Care Medicine
  • Hematology

Background:

  • The optimal red-cell transfusion strategy for patients with aneurysmal subarachnoid hemorrhage (aSAH) experiencing anemia remains unclear.
  • This study addresses the uncertainty surrounding liberal versus restrictive transfusion protocols during the critical care period post-aSAH.

Purpose of the Study:

  • To compare the effectiveness of a liberal red-cell transfusion strategy against a restrictive strategy in critically ill patients with aSAH and anemia.
  • To evaluate the impact of transfusion strategies on neurologic outcomes, functional independence, and quality of life at 12 months.

Main Methods:

  • Randomized controlled trial involving critically ill adults with acute aSAH and anemia.
  • Patients were assigned to either a liberal transfusion strategy (hemoglobin ≤10 g/dL) or a restrictive strategy (hemoglobin ≤8 g/dL).
  • Primary outcome was unfavorable neurologic outcome (modified Rankin Scale ≥4) at 12 months; secondary outcomes included functional independence (FIM) and quality of life (EQ-5D-5L, VAS).

Main Results:

  • No significant difference in unfavorable neurologic outcomes at 12 months between the liberal (33.5%) and restrictive (37.7%) groups (Risk Ratio 0.88; 95% CI, 0.72 to 1.09; P=0.22).
  • Similar mean scores for functional independence (FIM) and quality of life (EQ-5D-5L, VAS) were observed in both groups.
  • The incidence of adverse events was comparable between the liberal and restrictive transfusion strategy groups.

Conclusions:

  • A liberal red-cell transfusion strategy does not lead to better neurologic outcomes compared to a restrictive strategy in patients with aneurysmal subarachnoid hemorrhage and anemia.
  • Transfusion thresholds of ≤10 g/dL versus ≤8 g/dL did not significantly impact 12-month functional or quality-of-life outcomes in this patient population.
