How to rehydrate isoosmotic fluid loss

summary

Isotonic water loss is a very common phenomenon of water loss. For patients, if they lose too much water, they may be in shock and coma. Therefore, when they find isotonic water loss, they should be rehydrated in time. Let's talk about how to rehydrate isotonic water loss.

How to rehydrate isoosmotic fluid loss

First, isoosmotic dehydration is the most common symptom of water shortage in surgical patients; water and sodium are lost in proportion, so serum sodium is in the normal range, and the osmotic pressure of extracellular fluid is also normal. In order to reduce the loss of water and sodium, the causes of isotonic water loss should be treated as much as possible.

Second: for the reduction of extracellular fluid volume, isotonic saline or balanced saline can be used to supplement blood volume as soon as possible. Body fluid loss can be estimated according to the symptoms of pulse rate and blood pressure drop. Those who have reached 5% of their body weight can be quickly infused with isotonic saline or balanced saline. To restore blood volume, or according to the specific volume of blood cells to calculate the amount of fluid needed.

Third: according to the severity of dehydration, 1 / 2-1 / 3 of the fluid replacement volume can be supplemented within 4-8h for moderate and severe dehydration, and the rest can be supplemented within 24-48h. Pay close attention to the changes of the condition during the rehydration, and correct the amount of rehydration at any time according to the reaction after rehydration and the electrolyte condition monitored.

matters needing attention

Isotonic water loss can be rehydrated in the above way, which can make the patient replenish enough water in time, so that the patient's body can recover. This is a very good way for the patient. If someone around loses water, we can learn from the above way.
