(2) According to the nature of dehydration, the presence of acidosis and hypokalemia, etc., to determine the type of rehydration fluid.
(3) When replenishing fluids, the principle of replenishing potassium in urine is generally carried out firstly fast and then slow, firstly thick and then light, firstly salt and then sugar. The total amount of rehydration fluid should be replenished at the prescribed rate
(4) Rehydration fluid should include 3 components: cumulative loss, continued loss, and physiologic requirements.
(5) The key to rehydration lies in the first 24 hours of day 1. For severe dehydration, hypovolemic shock, and severe acidosis, the first step is to dilate and correct the acid, and then continue to replenish the cumulative losses, abnormalities, and continued physiologic losses. When the blood circulation and renal function are restored, the body itself will be able to regulate. In the process of correcting dehydration, pay attention to potassium supplementation.
