Phlebotomy in ICU

Q: How much blood a patient loses every day in ICU just by phlebotomy?

Answer: On an average 41 mL/day

The objective of above question is to highlight the need to avoid unnecessary blood draws in ICU. Apart from a direct blood draw, other measures which may help in conserving blood loss include small volume for sampling, point-of-care testing and others.
