Blood Supply And Demand Under The Epidemic Situation: Blood Donation Peak To Peak And Blood Peak

The impact of the new crown pneumonia epidemic across the country is still fermented by the various sectors of the healthcare industry.

"Because patients with elective surgery may have been overworked for a period of time to get together for surgery, the blood volume in March may reach a peak." Fu Yongshui, Party Secretary of Guangzhou blood center, told reporters in an interview with the economic news reporter twenty-first Century.

During the epidemic period, many hospitals reduced the flow of personnel, reduced the risk of cross infection in hospitals, reduced the number of hospitalized patients and postponed the operation period. As hospitals around the epidemic area begin to solve the surgical problems during the epidemic period, the volume of blood is expected to peak.

At present, one of the important sources of voluntary blood donation is the mobile blood donation vehicle and blood donation house arranged in densely populated public places. In winter, this is the low season of voluntary blood donation, plus the arrival of the Spring Festival, which makes a large number of students and workers returning to the countryside, which directly lead to a sharp decline in blood collection. In addition, during the Spring Festival, the drinking of healthy people increased, resulting in less qualified blood. In short, at the beginning of this year, due to many factors such as epidemic situation, season, weather, festivals and so on, it led to a "blood shortage".

Anti epidemic front: increased blood use and increased blood use

"We have transferred 500 units of blood to Wuhan before the Spring Festival, and if Wuhan still needs it, we will continue to deliver it." Fu Chung water means.

At present, the contradiction between supply and demand of blood products at epidemic fronts is more obvious, and blood banks in Hubei are frequently in urgent need. On the one hand, affected by traffic and delayed reemployment, the slurry and slurry schedule are limited; on the other hand, a large number of patients are badly in need of treatment, which greatly increases the demand for blood products.

Affected by the epidemic, the plasma pumping station in the whole country has been caught in a short "stop" operation. According to the quarantine requirements, the stock plasma needs to be qualified again after 3 months. In 2020, the pulp volume and pulp volume are expected to be affected.

According to China Merchants Securities estimates, the resumption of work at the end of February will lose nearly 1 months' slurry production period, and it is likely that the slurry volume will shrink by about 8% (1/12). However, the actual impact is expected to be less than 8%, and the average frequency of the pulp workers in the whole country is 5.2 times (the data of blood transfusion Research Institute of Chinese Academy of Medical Sciences and Beijing Union Medical College in 2015). The frequency is low (the maximum number of times is 24 times). By increasing publicity and input, it is possible to make up for the latter 3 quarters.

Slurry and slurry are limited, but the demand for blood products in the epidemic area is increasing. At present, the blood products widely used in the first line of anti epidemic are static propane (Human Immunoglobulin for Intravenous Injection). According to the published research article, "epidemiological characteristics and clinical manifestations of 99 cases of new coronavirus pneumonia in Wuhan, China": a descriptive study shows that 27% of the 99 cases of 2019-nCoV pneumonia diagnosed in Wuhan golden Yin Tan Hospital were treated with static propyl propane.

In addition to the treatment of critically ill patients, according to the Boya biopharmaceutical group Limited by Share Ltd (hereinafter referred to as Biya bio), in the acceptance of the agency's research, the first-line medical staff had more than 50% injected static propane to improve their immunity. In addition, 98% of the new crown pneumonia patients needed albumin in albumin.

In February 21st, the Chongqing Municipal Health Protection Committee transferred 1250 units of suspended red blood cells from Chongqing to Hubei, and 21 treated platelets collected nearly 260 thousand milliliters of blood.

Beyond the epidemic area: release of surgical backlog or use of blood peak

Outside Wuhan, "blood shortage" also exists.

Previously, because the new coronavirus is highly infectious, in order to reduce the possibility of cross infection in hospitals, many hospitals have shut down some or all clinics, suspended hospitalized patients, delayed the operation time of patients, and many patients in urgent need of surgery can only temporarily relied on conservative treatment to relieve their pain. A doctor at a third class hospital in Shenzhen told reporters on twenty-first Century economic report that the lack of plasma has led to numerous operations in hospitals.

In February 17th, the State Council joint defense joint control mechanism "guiding opinions on the prevention and control of new crown pneumonia" in the area of scientific prevention and control of precision policies, pointed out that in low risk areas, we should implement the strategy of "external defense input" to fully restore normal production and life order. In the middle risk areas, we should implement the strategy of "external input and internal non-proliferation", and restore the normal production and life rank as soon as possible. Preface. With epidemic prevention entering a new stage, the hospital has entered a period of adjustment.

With the resumption of production and rehabilitation in various places, hospitals around the world have begun to arrange operations for patients who have postponed surgery because of the epidemic. The predicted blood volume will peak.

Fu Chung said that with the recovery of patients receiving elective surgery, the volume of blood is expected to reach a peak by March. Under normal circumstances, we usually send 1200-1500 units of red blood cells per day, and 200-300 units of platelets. It is expected that by March there will be more than that, and it is expected to increase by about 10%.

Because of the epidemic, there are relatively few patients undergoing surgery. About 600-700 or so units of red blood cells need to be delivered every day, and then the platelets will probably produce 150 units. In this way, platelets and red blood cells can add up to 800 units to meet the needs. Over a period of time, the dosage is doubled in March. It is understood that Guangzhou needs more than 1100 people a day to donate blood to meet clinical needs.

At present, the Guangzhou blood center has actively mobilized team members to donate blood. Fu Yong water told the twenty-first Century economic news reporter that more than two thousand medical staff from more than 10 hospitals recently participated in the voluntary blood donation. Next, there are more than ten hospitals that have already made an appointment of the group's voluntary blood donation. At the same time, they also appeal to the general public to actively participate in voluntary blood donation.

The epidemic is not yet fully recovered, and blood safety is also an important issue. According to the notice issued by the national health and Health Committee in February 10th, in order to further prevent the disease and ensure the safe supply of blood, the health care workers of blood stations should strengthen the health consultation of voluntary blood donors.

"Before we donate blood, we need to add some additional requests to donors, such as whether we have visited the epidemic areas, have a history of close contact with the patients, etc., so as to prevent and control epidemic diseases and to achieve blood safety." Fu Yong water told reporters that at present, the virus can not be ruled out through blood transmission, the Guangzhou blood center will strengthen the consultation of blood donors.

Blood donors who have recently had a history of travel in Wuhan should be allowed to postpone blood donation. For ordinary blood donors, health checks should be strengthened, focusing on whether there is a history of exposure to high-risk groups and monitoring the blood temperature of donors. At the same time, inform blood donors such as fever, cough and other symptoms within one month after blood donation, to inform the blood collection institutions in time.
