I have a bruise on my arm after plasma transfusion. Why?

Hi,

Welcome to icliniq.com.

By looking at the picture and history provided (attachment removed to protect patient identity), I think it is a small dispersed hematoma because of leakage of blood from the blood vessels. As it has happened at the site of venepuncture, it is mainly because of inadequate expertise of nursing staff. The needle might have damaged the artery, as you were donating blood, leading to blood leakage and hematoma formation. At this point, I assume you do not have any allergy or bleeding or clotting disorders leading to such bruise at the site of needle insertion. My suggestion is to apply Thrombophob ointment (combination of Heparin and Benzyl nicotinate) at the site two to three times daily. It will slowly resolve over a week's period. If bruise grows and increases in intensity, then consult your local doctor immediately to find out any other potential causes. Thank you and take care. Regards.
