In order to ensure the quality of blood and reduce the unnecessary reaction of blood donors in the process of blood donation, blood donors should pay attention to the following issues on the day before and on the day of blood donation:
1. Don't overeat the night before blood donation, and don't eat meat, fish, eggs, milk, bean products and greasy food for the first two meals. Eat a light diet to prevent blood turbidity and affect blood quality.
2. Keep a good sleep the night before blood donation, and don't eat on an empty stomach before blood donation to avoid some reactions such as dizziness, palpitation and sweating during blood donation.
If you have a cold, fever, cough, etc. Two days before blood donation, blood donation should be suspended.
4. Before preparing for blood donation, you can also read some blood donation publicity materials to lighten the ideological burden and reduce unnecessary reactions in blood donation.
What problems should be paid attention to in the process of blood donation?
When donating blood, blood donors always need to be happy and full of honor. Under the guidance of the nurse, the elbows of both arms should be cleaned. When collecting blood, you should cooperate with the blood collection nurse to answer the name, age and blood type. Put the arm with good blood vessel exposure into the elbow well, and the position of the arm for blood collection should be as level as possible with the heart to keep the blood flow unobstructed. During blood collection, you should relax all over to avoid excessive pain caused by skin or muscle contraction affecting needle insertion. At the same time, you can actively consult nurses about blood donation to improve your understanding of blood donation knowledge. In addition, keep a moderate silence when donating blood to reduce unnecessary irritability. If you feel flustered, stuffy, sweaty, thirsty or unable to sit still, you should immediately tell the blood collection nurse or visiting doctor. So as to take treatment measures. When the blood vessels are thin or the blood flow is not smooth, we should actively cooperate according to the requirements of nurses. During the whole blood collection process, the arm should not move casually.
What problems should I pay attention to after donating blood?
After blood collection, blood donors should take a short rest at or near the blood collection site and should not get up in a hurry to prevent transient cerebral ischemia. At the same time, press the sterile cotton ball at the eye of the needle to avoid bleeding or subcutaneous congestion.
On the day after blood donation, we should pay attention to the cleanliness of needle eyes. It is best to take a shower when taking a shower. Do not use dirty water or soapy water to enter or irritate the eye of the needle to prevent infection.
After blood donation 1-2 days, appropriately increase the amount of drinking water, pay attention to supplement a little high-protein and digestible food, and avoid overeating. Pay attention to proper rest and don't engage in strenuous activities. Individuals who feel tired will soon disappear as long as they get enough sleep.
Blood donors should be happy after donating blood, because they have done a selfless and meaningful thing, and donating blood will not harm their health. However, if there are some adverse reactions after blood donation, you should get in touch with the blood collection unit and see a doctor in time.
The main raw materials for hematopoiesis are protein, iron, vitamin B 12, folic acid, etc. These nutrients are in the ordinary diet, so there is no need to eat more. After donating blood, add some nutrition appropriately, eat lean meat, eggs, bean products, fresh fruits and vegetables, etc. It can promote the faster recovery of blood components, but avoid overeating and drinking.
Link: Regular and moderate blood donation is good for health.
It is good to donate blood regularly and in moderation.
A large number of scientific studies have proved that blood donors not only contribute their love to the society, but also improve their physical condition and make "investment" for their health.
Scientists used hemorheology and hemodynamics to study the relationship between blood quality and blood donation. It is found that regular and moderate blood donation, especially a single donation of tangible components such as red blood cells and platelets, can significantly reduce blood viscosity and increase cerebral blood flow after speeding up blood flow, thus alleviating or preventing hyperviscosity, making people feel relaxed, clear-headed and energetic.
Blood donation also plays a positive role in reducing the occurrence of cardiovascular and cerebrovascular diseases. A research team in Finland investigated 2682 men aged 42-60. Among them, the proportion of people who donate blood at least 1 time in two years who have acute myocardial infarction in five years is 86% lower than those who don't donate blood. A study by a cardiovascular research group in the United States also shows that within three years, the risk of cardiovascular disease among blood donors (men) is only half that of non-blood donors.
Male blood donation can also reduce the incidence of cancer. International Cancer reports that if the iron content in the body exceeds 10% of the normal value, the probability of cancer will increase. Proper blood donation can regulate the iron content in the body and prevent cancer. The article also mentioned that young and middle-aged women lose a certain amount of iron in their bodies due to menstrual blood loss, so the iron content in these women has no obvious relationship with the occurrence of cancer.
Studies have shown that people who donate blood regularly are less prone to aging than those who don't donate blood, and have strong tolerance and self-regulation function in unexpected situations. Some scholars have made a prospective comparative study of 332 people over 66 (blood donors) and 399 people of the same age and sex (non-blood donors). The results showed that the average life expectancy of the blood donation group was 70. 1 year, which was higher than that of the non-blood donation group (67.5 years). Once an accident happens, the survival rate of the blood donation group is 67%, which is higher than that of the non-blood donation group (40%). From the above analysis, the life expectancy of blood donors will be prolonged because their blood metabolism is more vigorous than that of non-blood donors.
A large number of studies show that healthy emotions can communicate with the brain and other tissues and organs through the nervous system, body fluids and endocrine system, so that they are in a good state, which is conducive to the enhancement of human immunity and resistance. Blood donation is a noble character to save lives. Blood donors are in the best mood while helping others and being kind to others, which is beneficial to their health.
Male blood donation has many advantages.
Some studies believe that if middle-aged men donate 550 ml of blood every year, the risk of heart disease will be reduced by 86%. According to this study, when men are over 40 years old, body fat tends to accumulate due to the reduction of physical activity and the improvement of living standards, and many people's blood lipids are at a high level for a long time. Regular blood donation can reduce the viscosity of blood, which also reduces the hidden danger of arteriosclerosis.
International Cancer reports that when the iron content in human body exceeds 10% of the normal value, the probability of tumor will increase, and the incidence of cerebral thrombosis and myocardial infarction will also increase. Proper blood donation, especially for men, can increase the iron content of red blood cells in the blood. The content of iron in donated blood will be reduced appropriately, reducing the occurrence of the above diseases.
Through a large number of investigations, scientists have found that young women are less likely to suffer from stroke, heart disease and tumor than men, but the chances of suffering from these diseases will increase with age. Through the analysis of the reasons, it is believed that the reduction of monthly menstrual flow of young and middle-aged women accelerates the metabolism of red blood cells, promotes bone marrow hematopoiesis, increases the number of newborn red blood cells in the blood, and transports more oxygen and nutrients to all parts of the body, thus reducing the risk of heart disease.
