MCQ (Single Correct)+4−1
What is a major theoretical concern regarding the administration of stroma-free Hb solutions?
Adverse Effects of Stroma-Free Hemoglobin: A major pharmacological complication of administering acellular or stroma-free hemoglobin solutions (HBOCs) is severe vasoconstriction and systemic hypertension.
Mechanism: Free tetrameric/dimeric hemoglobin readily extravasates through endothelial pores into vascular smooth muscle, avidly scavenging endogenously produced nitric oxide (NO / EDRF) and triggering profound systemic and pulmonary vasoconstriction.
Correct option: (2) Vasoconstriction
