Overview
Clinical Orientation
Aplastic anaemia is a failure of blood cell production, not simply a low haemoglobin problem.
Aplastic anaemia is a failure of blood-cell production, not simply a low haemoglobin problem. Because red cells, neutrophils, and platelets may all be reduced, the same patient can have fatigue from impaired oxygen delivery, infection risk from loss of neutrophil defence, and bleeding from inadequate primary haemostasis. The count that is most urgent depends on what is happening clinically. Fever or subtle deterioration in a profoundly neutropenic patient can signal rapidly progressive infection; new bleeding can become dangerous with little warning; dyspnoea, chest discomfort, or tachycardia may reflect clinically significant anaemia. The sections that follow connect the pancytopenia pattern to diagnostic confirmation, treatment selection, and RPN monitoring priorities.
