Why is the speed of intravenous albumin slow

summary

Intravenous infusion of albumin can provide patients with nutrients, which is still very good for patients. However, during infusion, many people find that the infusion speed is very slow, so why? Let's talk about why the infusion speed is slow.

Why is the speed of intravenous albumin slow

First, the role of albumin is mainly to regulate the dynamic balance of water between tissues and blood vessels. Due to the high molecular weight of albumin, the speed of albumin penetrating through the membrane is slower than that of salts and water, which makes the colloidal osmotic pressure of albumin compete with the static pressure of capillary, so as to maintain normal and constant blood volume;

Second: normal saline is a buffer for dilution. If the protein content in plasma suddenly increases, the osmotic pressure of plasma will increase, resulting in a large amount of water in tissue fluid flowing to plasma, resulting in a higher concentration of dehydrated albumin in tissue than that in blood. If it is not diluted by normal saline and dripped slowly, it will cause edema and increase the burden of heart and lung.

Third: increase blood volume and maintain plasma colloidal osmotic pressure: albumin accounts for 80% of plasma colloidal osmotic pressure, mainly regulating the dynamic balance of water between tissues and blood vessels. Due to the high molecular weight of albumin, the speed of albumin penetrating through the membrane is slower than that of salts and water, which makes the colloidal osmotic pressure of albumin compete with the static pressure of capillary, so as to maintain normal and constant blood volume.

matters needing attention

After the above description, it can be seen that the dropping speed of intravenous infusion of albumin must be slow. If the content of albumin in the human body suddenly rises, the patient may feel uncomfortable, so it is absorbed slowly. This is also very good for the human body, and it is also good for the body.
