Such iatrogenic anemia can be caused by hemodilution due to the routine administration of non-oxygen carrying crystalloids solutions, often in large amounts resulting in a reduced number of circulating oxygen carrying red blood cells.
Next to this rather obvious reason for anemia, iatrogenic anemia induced by myelosuppressive drugs is also very common.
To prevent iatrogenic anemia from frequent blood draws, preanalytical as well as analytical systems should be capable of handling small sample volumes collected in pediatric tubes (2).
Some investigations were limited to adverse drug events (ADEs), while others concentrated on very specific problems, such as iatrogenic anemia or ulnar nerve injury.
Iatrogenic anemia in hospitalized patients, not an uncommon occurrence, has been traced in studies to the amount of blood drawn over time.
The need for repeated attempts to collect blood also increases the risk of iatrogenic anemia in patients, as well as risk of transmission of bloodborne pathogens to nurses and phlebotomists.
Proper blood-draw volume on infants is usually determined at the institutional level using a weight-based equation to ensure that iatrogenic anemia does not occur.
Sherry Woodhouse's article on iatrogenic anemia is another well-written piece about a topic often overlooked in hospitals.
Another critical care complication has developed -- iatrogenic anemia.
Therefore, iatrogenic anemia due to lab testing is a constant threat.
Iatrogenic anemia occurs when too much blood has been collected from a patient, causing additional medical problems.
As a result, we found our results are insensitive to change in many key areas, such as test cost, number of blood analyses performed, and factors associated with VAs, cardiac arrest, and iatrogenic anemia.
