What are the symptoms after donating platelets???

Thrombocytopenia, easy to cause ** submucosal hemorrhage, it takes a period of time to rely on hematopoietic tissue generation, after donation, you need to enhance nutrition, eat more vitamin-rich food, enhance nutrition, avoid overwork, rest well, generally about two months can return to normal. Satisfied.

Platelets are small discoid cells that exist in large numbers in the blood, and the number of platelets in the blood of adults is 100 300 1000000000 L, it has a plasma membrane, no nuclear structure, is generally round, and the volume is smaller than red blood cells and white blood cells. Platelets are seen as non-functioning cellular debris in the blood in the long term. Platelets have a specific morphological structure and biochemical composition, and have a relatively constant number in normal blood (for example, the number of human platelets is 10.3 million per cubic millimeter), which plays an important role in physiological and pathological processes such as hemostasis, wound healing, inflammatory response, thrombosis and organ transplant rejection.

Unpaid platelet donation is also a way to donate blood for free. There is no big difference between unpaid platelet donation and participating in whole blood donation, it does not harm human health, but it takes more time to participate in whole blood donation, and platelet donation is about 10 minutes to lie quietly next to the blood cell separator for about 1 and a half hours.

In addition to meeting the general blood donation conditions, platelet donors must meet the standards for white blood cell count, red blood cell count, platelet count, hematocrit and other blood cell counts. Platelet donation in appropriate amounts by healthy people does not harm their health. Based on the metabolism physiology of blood cells, even if there is no donation, about 10% of platelets in the human body age and die in the blood, and the recovery of platelets is faster than that of red blood cells.

Please believe that modern medicine will never harm one person in order to save another).

There are four points to pay attention to when donating platelets: eat a light diet the day before, and do not eat high-fat foods, such as meat, eggs, dairy products, soy products, peanuts, melon seeds, etc., so as not to produce fatty blood; Excessive drinking, staying up late, fatigue, drugs, etc., can easily cause high aminotransferase (ATL) and cause blood waste; Avoid fasting platelet collection to prevent and treat adverse reactions to blood donation; After platelet donation, the needle hole should be intravenously pressed with three fingers for 3-5 minutes, the cotton ball at the needle hole should be retained for at least 4 hours, and the venipuncture site should be kept clean for 12 hours.

It is not difficult to recuperate, do not engage in high-altitude work, hot work, driving vehicles, sports competitions, all-night entertainment and other activities on the day.

Supplement fresh vegetables and fruits, soy products, dairy products, fresh fish, shrimp, meat and eggs, etc., but not too much more than usual, and you can also supplement some nutrients appropriately.

Because the amount of platelet collection is fixed, but the concentration of platelets in each person's unit blood is different, there should be no difference in whether the difference will be made or not, and now it is also promoting ingredient blood donation! After all, it's easy for people who donate whole blood.

Platelets are substances that promote blood clotting, and the reason why we can stop bleeding quickly after injury depends on it and the coagulation system in the body. If the platelets are low, they will leave bruising after a collision.

The normal range of human platelets is about 100-300*10 (9 power) l, after donating platelets, there is a "home remedy", that is, "three reds" - brown sugar, red dates, and red-skinned peanuts, boiled together in soup and drunk, sweet, and the effect of raising blood is good. Nutrients should be added to the daily diet, eating more chicken, duck, fish, meat, milk and soy products. Choose foods that contain more iron such as liver, kidneys, heart, lean meat, and egg yolks.

Vegetables to spinach, celery, tomatoes. Among the fruits are apricots, peaches, plums, raisins, red dates, polo, figs, etc. You can also choose stewed black chicken, peanuts and other blood supplements.

Platelets live for about 7 to 14 days, and are renewed about 1 to 10 of the total amount per day, and most of the senescent platelets are cleared in the spleen.

The blood cell separator is used to collect platelets from the systemic blood of a healthy person for a single dose, and other blood components of the collected person are immediately transfused back to the person, which is called machine platelet collection. The interval between machine-collected platelet donors is one month, because platelets recover faster than red blood cells, and the platelets in the circulating blood can be restored to the pre-collection level within 3 days after the donor collects platelets.

Donation at the specified time has no effect on the body, therefore, platelet collection will not affect the health of the blood donor.
