1. Vasovagal effects:
A feeling of light-headedness or faintness which may progress to an actual faint during or immediately after donation.
This can be avoided by drinking non-alcoholic fluids (i.e. water and/or juice) within three to four hours prior to and after donation. Our well trained staff members are especially skilled in the treatment of faints by administering intravenous fluid when necessary. Do not hesitate to mention to staff that you are feeling dizzy after a donation as it may indicate that your blood pressure has dropped.
2. Injury to soft tissue as a result of venepuncture:
Bruising or haematomas can arise after a donation.
To avoid these, tightly compress the puncture site until bleeding has stopped, keep the plaster on for six hours following donation and do not lift heavy objects with the arm during the day.
