What amount of IV fluid for dehydrated patient?

The amount of IV fluid for a dehydrated patient depends on several factors, including the patient's age, weight, medical history, and the severity of dehydration. As a general guideline, the following formula can be used to estimate the initial fluid requirement:

For adults: 1,500-2,000 mL/day + (deficit volume)

For children: 100 mL/kg/day + (deficit volume)

The deficit volume is the estimated amount of fluid that the patient has lost due to dehydration. This can be calculated by assessing the patient's skin turgor, mucous membrane moisture, pulse rate, and blood pressure.

In addition to the initial fluid requirement, the patient may also need maintenance fluids to replace ongoing losses. Maintenance fluids are typically provided at a rate of 1,500-2,000 mL/day for adults and 100 mL/kg/day for children.

It is important to note that these are just general guidelines and the actual fluid requirements for a dehydrated patient may vary. The patient's healthcare provider will determine the exact amount of IV fluid that is needed based on their individual assessment.
