China News Service Client, Beijing, June 14 (Reporter Zhang Ni) During the epidemic, blood is as important as a mask and medicine for life protection. Many critically ill patients need blood to treat diseases. Is the national blood stock still enough during the special period? With the advent of World Blood Donor Day, these issues related to the life and health of patients have once again attracted attention.

Support 46,000 units of red blood cells for blood transfusion in Hubei

  This year, affected by the new coronary pneumonia epidemic, the number of unpaid blood donors has dropped in many areas. Hubei, as the most severely affected province, including Wuhan, Yichang, Shiyan and other places have experienced "blood bank emergency", causing public concern.

  In order to guarantee the clinical blood supply during epidemic prevention and control, as early as January this year, the National Health and Health Commission issued a "Notice" requesting the establishment of a two-level linkage mechanism for blood security, clarifying Anhui, Jiangxi, Hunan, Chongqing, Shaanxi and Henan provinces The city provides blood counterpart support to Hubei Province, and Sichuan, Yunnan, Hebei, and Guangdong provinces have also joined the ranks of supporting Hubei.

  In the province, in the face of epidemics, Hubei has also perfected the blood emergency guarantee mechanism in accordance with the principle of self-collection and supplementation.

  According to the information released by the National Health and Health Commission, in the early stages of the epidemic and entering the low-risk period, Hubei Province tapped its potential and actively carried out unpaid blood donation recruitment. Each blood station adjusted the unpaid blood donation recruitment model and used telephone and Internet to recruit blood donors. Measures such as blood donation appointment, directional service, private car transfer, and enhanced protection will maximize the blood collection capacity under the premise of ensuring the safety of blood donors and staff.

  In addition, in the critical period of the prevention and control of the new coronary pneumonia epidemic, the plasma of the recovered patients of the new coronary pneumonia in the recovery period has become a powerful weapon for the treatment of critical and critically ill patients.

  Data from the National Health and Health Commission show that the five brother provinces of Hunan, Henan, Anhui, Jiangsu, and Shanxi timely allocated plasma for the recovery of patients with new coronary pneumonia in Hubei Province, which effectively supported the treatment of patients with new coronary pneumonia in Hubei Province.

  As of April 15, a total of 12 provinces and cities have provided support to Hubei Province with a total of 46,000 units of red blood cells, 1,856 platelets, and 22,000 milliliters of plasma in the recovery period of new coronary pneumonia patients.

Make an appointment online, collect blood at your door...

  During the epidemic, many places across the country also took different measures to deal with the possible "blood shortage" in the region.

  Taking Zhejiang as an example, blood collection and supply institutions around Zhejiang have prepared emergency plans in advance and initiated emergency response to formulate blood collection and supply response plans.

  Zhejiang has also urgently developed a province-wide blood donation information system, which is open to the public through Alipay's electronic blood donation certificate. The provincial blood center has launched a 96614 open consultation service hotline to answer questions for loving people.

  In addition, for individual blood donation, through online consultation, staged appointments, environmental reconstruction, and strict flow control; for group blood donation, according to the "five-color map", establish a province-wide blood emergency linkage management mechanism for classified development, centralized management, and linkage guarantee. In areas with severe epidemics, blood donation is the predominant appointment, and counties (cities, districts) with confirmed and zero reports have increased the mobilization of blood donation groups, recruiting units with team blood donation experience through multiple channels, and organizing door-to-door collection in batches and periods.

  In Nanning, Guangxi, in May this year, the Nanning Central Blood Station opened the blood collection RV.

  Compared with common large blood collection vehicles, blood collection vehicles have much lower requirements for driving and parking conditions, and can provide more convenient on-site blood collection services during the new coronary pneumonia epidemic. In addition, the blood collection RV can also penetrate into towns and villages, and play the functions of mobile publicity and mobile blood collection.

A few days ago, the National Health Commission and other departments jointly produced and released the 2020 free blood donation promotional film "Thank You-Tribute to Unpaid Blood Donors". The picture is a video screenshot.

  At the same time, many more enthusiastic people took the initiative to roll up their sleeves at a special time and dedicate their blood to save the lives of others. Among them are soldiers, students, ordinary employees, and even some well-known public figures.

  For example, on March 31 this year, Yao Ming, chairman of the Chinese Basketball Association, and Bai Xilin, secretary-general, led the staff of the Chinese Basketball Association to form an unpaid blood donation team and participated in the unpaid blood donation in the blood donation square of Dongzhimen in Beijing. In this blood donation event, a total of 11 people donated blood, donating a total of 2400 ml of blood, of which Yao Ming took the lead in donating 400 ml of blood.

  In April of this year, Li Shan, a former Chinese female volleyball player and Athens Olympic champion, also participated in free blood donation, which caused many netizens to praise.

  Data from the National Health and Health Commission show that from January to April 2020, the national blood stocks have been above the safety line.

The online information service system of the national electronic unpaid blood donation certificate is more perfect

  Under the epidemic situation, the public witnessed the efficient linkage between the whole country, and the domestic clinical blood guarantee mechanism is also constantly improving.

  Since the implementation of the "Blood Donation Law" in 1998, the number of unpaid blood donation visits and the volume of blood collected in China have achieved continuous growth for 20 consecutive years.

  Data from the National Health and Health Commission show that there were about 300,000 unpaid blood donors nationwide in 1998, and nearly 15 million in 2018. The total blood collection nationwide in 1998 was less than 5 million units, and in 2018 it reached more than 25 million units, an increase of more than 4 times.

  By the end of 2018, China had set up 32 blood centers, 321 central blood stations, 99 central blood banks, and 3164 blood collection points. The World Health Organization has evaluated that China ranks among the top in the world in terms of unpaid blood donation, blood quality and safety, and clinical blood use.

  Relying on Internet information technology, the domestic free blood donation has also entered the "smart interconnection" era.

  In recent years, with the overall promotion of the National Health and Health Commission and the joint efforts of blood collection and supply institutions across the country, and relying on a unified interface service, the data of 452 blood collection and supply institutions across the country has been interconnected, and more than 600 million pieces of blood donation love information Converge.

  From June 14, 2020, the nationwide electronic "unpaid blood donation certificate" will be officially launched. Relying on the nationwide unified electronic "unpaid blood donation certificate", the blood expenses for unpaid blood donors and their immediate family members will be reduced directly.

  The unpaid blood donation information service system, which integrates many functions into one, is ready to come out, and the nationwide unpaid blood donation work will also achieve high-quality sustainable development.

How much do you know about the knowledge of blood donation?

1. Is blood donation harmful to health?

  Generally, the amount of blood donated each time (200 ml or 400 ml) is about 5% to 10% of the total blood volume of the human body, and will not damage health. After donating blood, the blood normally stored in the liver, spleen and other organs will be "dispatched" to maintain the blood supply. At the same time, "hematopoietic factories" such as bone marrow will accelerate blood production. Studies have shown that in about 2 weeks, various blood components of the body will return to the level before blood donation.

2. Will blood donation infect diseases?

  The "Blood Donation Law" stipulates that blood collection stations must strictly follow operating procedures and systems, blood collection must be performed by qualified medical personnel, and disposable blood collection equipment must be destroyed after use to ensure the health of blood donors.

  Blood collection stations use strictly sterilized disposable medical equipment, which must meet the requirements of national standards; after use, medical wastes such as blood bags and needles must be handled in strict accordance with the regulations, centralized destruction, and will not be reused , So blood donation will not infect the disease.

3. Will blood donation be addictive?

  As far as human physiology is concerned, blood donation is only a small amount of blood loss, and there is no mechanism or reason for "addiction".

4. Will you gain weight after donating blood?

  A normal diet after blood donation will not cause weight gain. However, some blood donors think that they need to make up after donating blood, excessive intake, resulting in excess nutrition, which may be the real reason for "get fat after blood donation".

5. Why encourage "component blood donation"?

  There are many components in the blood such as red blood cells and platelets. The components required by different patients are different. Component blood donation refers to the process of collecting a certain blood component by means of a blood cell separator (a platelet is commonly collected in China), and other components will be safely returned to the body.

6. Do you need rest and supplement after blood donation?

  Do not engage in vigorous physical activities within 24 hours after blood donation, pay attention to a balanced diet, but there is no need to "add up" extra. A few people will feel tired, should pay attention to rest and ensure adequate sleep. Usually, one to two days after blood donation can resume daily life. (Finish)
