Investigation: dhr could not be assessed as the customer was unable to provide the lot number.All lots must meet acceptance criteria for release.The reported adverse events are common side effects of apheresis donations.According to aabb technical manual 16th edition, adverse reactions seen at the time of donation or those reported later average about 3.5% of donations.Reactions that need medical care after the donor has left the donation site are seen in 1 in 34 donors.Vasovagal reaction complex includes dizziness, sweating, nausea, vomiting, weakness, apprehension, pallor, hypotension, and bradycardia.In severe cases, syncope and convulsions may be observed.The pulse rate is often low during vasovagal reactions while the rate is often high during volume depletion.Some donors with severe reactions or those with prolonged recovery times may need short-term observation, intravenous fluid administration in the emergency room, or both.There is no evidence to suggest a malfunction of the disposable set or the trima device caused or contributed to the reported adverse reactions.Root cause: a specific root cause for the reported reaction could not be determined.The reported adverse reactions are common side effects of therapeutic apheresis procedures.They are typically caused by fluid shift, blood loss, length of the procedure, donor's sensitivity to the procedure and/or hemodynamic stress of the procedure.
