For patients older than 14 years with thermal burns, how much fluid is to be administered?

For patients older than 14 years with thermal burns, the appropriate calculation for fluid resuscitation is based on the formula of 2 ml of lactated Ringer's solution (LR) multiplied by the patient's weight in kilograms and the percentage of total body surface area (TBSA) burned. This formula is consistent with the guidelines established by the American Burn Association for initial fluid resuscitation in burn patients.

Using this method achieves the goal of adequately restoring circulating blood volume and perfusing vital organs while minimizing the risk of complications associated with over-resuscitation, such as pulmonary edema or systemic complications. This approach emphasizes the importance of tailoring fluid resuscitation to the specific needs of the burn patient, taking into account body weight and the severity of the burns as indicated by TBSA.

In contrast, the other options suggest higher volumes of fluid administration that are not supported by the established guidelines for this patient population and could potentially lead to adverse effects.
