Determination of the Minimum Discard Volume in the Extraction of Blood Samples Through Arterial Catheters in Critical Patients

Key Points

• This research aims to identify the minimum discard volume required when collecting blood samples to minimize iatrogenic anemia in critically ill patients.
• Evaluated different discard volumes for blood samples collected through arterial catheters.
• Assessed the impact on the incidence of iatrogenic anemia.
• Analyzed cost implications of reducing blood transfusions related to anemia.
• Identified a minimum discard volume that effectively reduces iatrogenic anemia.
• Demonstrated a decrease in the need for blood transfusions.
• Showed potential cost savings associated with reduced transfusion therapies.
