China News Service, Beijing, June 14 (Reporter Yuan Xiuyue) Does donation of blood affect the body? Does "Panda Blood" affect health? Do you still believe in the misunderstanding of some blood donation?

June 14th is World Blood donor day. The column of "Medicine of Medicine" in China News Network specially invited Zhu Yuqi, director, chief physician, and graduate tutor of the Ophthalmology Hospital of the Chinese Academy of Traditional Chinese Medicine, Guo Jin, deputy chief technician of Beijing Red Cross Hemoristic Center, Beijing Qi Xuming, the "parent" of the city's Red Cross Heritage Center, "Parents", talked about the story of donating blood freely.

What conditions should I meet? Don't believe these misunderstandings!

At present, more and more people have joined the blood donation team. According to the previous introduction of the National Health and Health Commission, the number of blood donation in my country has continued to increase, from 328,000 in 1998 to 15.53 million in 2020, an increase of 47 times.

But at the same time, there are not many people who know much about blood donation, or they know some "wrong knowledge".

Guo Jin, deputy chief technician of the Beijing Red Cross Hemoristic Center, introduced that regarding blood donation, my country specifically compiled the "Health Inspection Requirements for Blood donors", which clearly listed various requirements for blood donation.

First of all, healthy citizens aged 18-55 can participate in free blood donation. If you have participated in the free donation of blood and have no adverse reactions, and if you are willing, you can extend to the age of 60.

In addition to age, there are general health indicators such as weight, blood pressure, pulse, and body temperature. Before donating blood, you need to do some healthy medical examinations and tests. Please fill in the health consultation documents to provide blood from his personal health history, life history, and travel history. , Judge that it can donate blood. She suggested that she did not need to be too nervous before donating blood. She had a light diet, not drinking, and sleeping well at night.

There have been rumors for a long time that blood donation will cause damage to the body. Is this that? Guo Jin clarified that in fact, the free donation of blood without compensation has no damage to people's health.

She explained that although blood donation is a process of blood loss, it has a small impact on the loss of blood volume. A 50 kg of adults, the total health of the body is about 3500-4000ml, and the amount of blood donation is 200 or 400ml each time, which is less than 10%of the total blood volume. The WHO believes that a healthy adult does not exceed 13%of his total blood volume, and has no adverse effects on the body.

Some people also report that there will be symptoms such as dizziness and fatigue after donating blood. Is this normal? Guo Jin said that most blood donors will not have adverse reactions after blood donation. However, due to individual differences, there will be a few blood donors that have mild dizziness and even briefly fainted. This is a normal physiological reaction.

In this regard, she suggested that blood donors drink more water within four hours after blood donation. Do not engage in physical or severe sports on the day of blood donation. Do not stay up late. After taking a good rest, these situations will be recovered quickly.

"I personally think that the biggest benefit of blood donors is also that it can promote the establishment or maintaining a healthy lifestyle and concept. In addition, the psychological happiness and harvest of life brought by life are also important. The face. "Guo Jin said.

Will "Panda Blood" inheritance? Does it affect health?

Rh negative blood, because of its rare, is also called "panda blood" in China.

Qi Xuming, the "parent" of the love home of the Red Cross Blood Center in Beijing, introduced that the RH blood type and ABO blood type are two blood type systems closely related to clinical blood transfusion. If a person's red blood cells have a resistance, then it is positive blood. If there is no resistance, then it is negative blood, which is the RH negative blood we said.

"The distribution of RH negative blood is closely related to human race, like the proportion of RH negative blood in Europe, which is about 15%, but among the Han people in my country, only three thousandths are the proportion. Type A, RH -negative B, RH -negative O, and RH -negative AB type, the ratio is about 3: 3: 3: 1. That is to say, the RH -negative AB type is rare Small than one thousandth. "Qi Xuming said.

So, will Rh negative blood be inherited? Does it affect health? Qi Xuming said that Rh negative blood will be inherited, but it does not affect physical health. It should be noted that in general, Rh -negatives cannot accept the blood of RH -positive. Rh -negative pregnant women must explain the blood type with the doctor in advance, and regular antibody screening is performed regularly during the surrounding health care process.

In order to ensure the blood supply of rare blood types, the Beijing Red Cross Blood Center established a rare blood type love home in 2001. All members are Rh -negative blood donors.

She shared that the most impressive was a burning patient, with a severe burns of 50%of the whole body. At that time, the epidemic situation was tight, and there were few people on the street, and patients were urgently needed to perform skin graft surgery. The premise of skin graft surgery is blood, and a 2000ml RH -negative O blood is required to do a arm. After receiving the notice, the friends of the Love House began to rescue people. Today, five people come to donate blood. Ten people will donate blood tomorrow and have been dedicated to the patient recovery and discharged. According to statistics, about 60 blood donors before and after were relayed.

"They usually come from all walks of life in life, including courier brothers, company boss, professor, and kindergarten head, police, and truck driver. When they receive an emergency blood donation notice, they will not hesitate to let go of their work, Come to the blood center to donate blood, so we call them the "Panda Heroes", all have a chivalrous heart. "Qi Xuming said. "You not only cured my illness, but also saved my life with blood"

"Blood donation is a kind of unity. Join us and save life." This is the slogan of this year's World Blood donor day, and it also reveals the significance of blood donation to save others' lives.

"More than thirty years ago, I worked at the grassroots level. One winter, it was very late. A three or four -year -old child was hugged to see the doctor. His face was pale. The only way for a child is blood transfusion, and it is still AB. At that time, there was no good blood collection institution and blood supply. What should I do? I remember that my lover was AB, so I called her to test, donate blood, and finally donated blood. Finally The child turns danger into peace. From this matter, I feel that blood transfusion rescue is very important. I think I must be a volunteer who donates blood for free. "

Speaking of the process of associating with blood donation, Zhu Yuqi, director, chief physician, and master's tutor of the Ophthalmology Hospital of the Chinese Academy of Traditional Chinese Medicine, still remembers it. He has been donating blood in 1998, and has persisted for 24 consecutive years. He contained more than 56 times of blood and platelets.

"Doctors who rescue the wounded" plus "long -term free blood donors", Zhu Yuqi's story has too many scenes that save people in crisis.

Zhu Yuqi recalled that in the past, the names of the blood would be written on the blood transfusion bag. During the operation, the blood needed to verify the blood transfusion and the patient's name.

Once Zhu Yuqi had surgery for the patient, he used his own blood. The nurse wondered when he heard that this "Zhu Yuqi" would not be our director. Later, the patient recovered very well after surgery. He also sent Jinqi before leaving. Thanks to Zhu Yuqi, "You not only cured my illness, but also used blood to save my life."

In order to ensure blood quality, Zhu Yuqi did not smoke or drink all year round, maintaining a healthy diet, and his physical condition has always been good. It is no problem to run for three or five kilometers. The people around him often said that he was like a young man.

"Gift to roses and leave the incense in hand, this feeling is very good." Zhu Yuqi said. (Finish)
