Whether albumin injections, i.e. injections of albumin, are beneficial to the elderly on a regular basis needs to be determined by the circumstances. If one wishes to have albumin injections only because of a recent self-perception of malnutrition, there is generally not much point in doing so, and there may even be an associated burden on the body or a risk of disease transmission. Albumin injections should be given only when the elderly person shows relevant indications of disease or after the doctor has recommended the use of albumin. Although albumin injection has certain advantages, it also has certain disadvantages, which need to be viewed correctly.1. Advantages: Albumin is the main component of human serum, which can play a role in improving immunity and maintaining plasma osmotic pressure. Elderly people suffering from hypoproteinemia can supplement their nutrition by injecting albumin to achieve the purpose of diuresis and swelling, and treatment of diseases. Elderly people who suffer from severe malnutrition or massive ascites due to long-term chronic diseases can also improve colloid osmotic pressure by injecting albumin, thus reducing ascites. However, it should be noted that albumin should be used at intervals to avoid causing further aggravation of ascites; 2. Disadvantages: albumin belongs to blood products, and some viral transmission diseases can be transmitted through blood, such as hepatitis B, hepatitis C, syphilis, AIDS and so on, so injection of albumin is also subject to certain risks. Moreover, albumin is a consumable product, which can only help the body to control the symptoms of related diseases for a short period of time, and can be metabolized in 2-3 days, and cannot exist in the body for a long period of time, which is poor in durability. For the elderly with kidney disease accompanied by a large amount of proteinuria, the injected albumin will flow out of the kidneys in a short period of time, and this process will aggravate the burden of the kidneys, thus speeding up the development of the disease. For the elderly with poor heart function, injecting too much albumin may cause water and sodium retention in the body, resulting in the occurrence of cardiogenic edema. Elderly people in normal state can start from dietary aspects, timely supplementation of albumin, such as daily intake of 2-3 eggs, moderate consumption of milk, etc., not only can improve the body’s immunity, but also to avoid the emergence of serious complications. Injections of albumin, on the other hand, need to be selected according to the specific circumstances and under the guidance of the doctor, in order to avoid causing further aggravation of the disease.
