Platelets Donation Risks
Last year I got a hematoma after donating platelets. Today, I had to stop a donation due to hematoma risk. Is donating once or twice a month too much?
NO: NO- your blood is always checked before donation. You can certainly donate once a month without issues; however, I advise consulting with your PCP regarding hematoma (usually related to the venipuncture). ...Read more
Pheresis: Is essence is a process where blood is "filtered" to extract either cellular products, red cells, white cells or a substance for either re-infusion (cell) or removal a macroglobulin in plasmapheresis in waldenstrom's macroglobulinemia. ...Read more
Yes, watch set up: The entire "plumbing" set for the machine comes out of one (sterile) package, then the IV solutions are opened and added (one time use). When you are all done, the entire works (minus the platelet collection bag!) is taken down and disposed of. ...Read more
Not by much: Platelet apheresis returns almost all the non-platelet blood components to you, so WBC and RBC levels usually do not change at all. Platelet count may drop briefly, but our bodies rapidly manufacture them, since it does not know if you donated them or if you sustained an injury that used them, it can adjust level within a few hours. ...Read more
Is the infusion of citate during a platelet donation safe? I have read that the comlication of hypocalcemia can be life threatening.
Citrate does chelate calcium and can cause symptoms of hypocalcemia. However, in a person healthy enough to donate blood/platelets, the liver can metabolize citrate fast enough so that it is not a problem. You may take calcium containing antacid to hasten recovery.
I applaud you for donating blood and doing your civic duty.
Wish you good health. ...Read more
I regurally donate plasma and platelets. Since my last donation, I have a small bump at the injection site. It’s been a few weeks, now. Common?
HEMATOMA: Following blood drawing it is not uncommon to form a hematoma at the injection site. This is due to some leakage of blood around the needle. The blood becomes trapped under the skin and can form a hard area. This will resolve over several weeks. Warm compresses to the area will help it to dissolve. ...Read more
Clotting disorder: Too high a platelet count may cause blood clots to form in blood vessels and deprive affected tissue of blood supply. Too low platelet count causes bleeding, usually in skin and mucus membrane, but can result in internal bleeding it the count is too low, i.e., less than 10 k/cmm. ...Read more
Essential: Thrombocytosis is a seemingly benign over-production of platelets but has a tendency to lead to clots and strokes, and may be a true myeloproliferative (leukemia like) disorder. You need to see a hematologist/oncologist to seal the diagnosis and discuss the need for treatment and options. ...Read more
Complicated.: This is a great question. The major worry of platelets being too lowis unexplained bleeding into the head, which can be very serious. This risk is present at different levels for different patients. It depends on quite a bit of variables: age, recent injury, other illnesses, current bleeding, chance of platelet recovery, etc. Clearly if there is troublesome bleeding, they are too low. ...Read more
Clumping together: Platelets are sticky cells thus they can stick and clump together. As a result of platelet clumping, platelet counts reported by automated counters may be much lower than the actual count in the blood because these devices cannot differentiate platelet clumps from individual cells. ...Read more
Bleeding: Platelets help our bodies clot. SO, when platelets are too low (how low is "too low" is very situation and individual dependent!) we will bleed. Often bleeding from low platelets takes the form of bleeding in the mouth and gums. Sometimes a dotted pattern, almost like a rash, called petechiae, can appear on the calves and shins. ...Read more
Depends: To increase platelet counts, you need to know what is making them low. Platelet transfusions can be given in certain situations. Treatments like ivig or steroids can help in some situations. Splenectomy will help in some situations. There are not any particular foods or vitamins that will raise platelet counts. ...Read more
Control bleeding: Platelets monitor blood vessels and if there is injury, stick to the site of injury (adhesion) and then release chemicals that attract other platelets (release reaction). Other platelets respond by being drawn to the area of injury and attaching to the growing platelet plug (aggregation). Activated platelets also provide a surface that supports blood clotting (coagulation). ...Read more
