The importance of proper fluid therapy in the initial management of burned patients has been emphasized repeatedly.1 Since fluid and electrolyte losses following burns are related to the size of the patient and the percentage of body surface burned, various formulas have been evolved for the estimation of the amount and type of fluid required in the first 48 hours after injury. Almost all surgeons use some type of formula or rule as a guide to early fluid requirements. The principal advantage of formulas is that they permit rapid estimation of fluid requirements; their principal disadvantage is that they may be misinterpreted as a substitute for clinical judgment and close observation of the patient. It must be stressed forcefully that in burns, as in all fluid problems, the response of the individual patient ultimately determines the details of fluid therapy.
A few years ago, a formula for fluid therapy
