What is the recommended timing for delivering fluids based on Parkland's Formula?

The recommended timing for delivering fluids based on Parkland's Formula is to administer half of the total calculated volume in the first 8 hours following a burn injury, and the remaining half over the subsequent 16 hours. This method is designed to provide appropriate fluid resuscitation while preventing complications that may arise from either over-resuscitation or under-resuscitation.

The rationale behind this timing is tied to the physiology of burn injuries. During the first hours after a severe burn, patients are at an increased risk of shock and require immediate fluid resuscitation to maintain blood pressure and organ perfusion. Delivering half the total volume in the initial 8 hours addresses the early critical period, while the remaining fluid over the next 16 hours allows for ongoing support as the patient's condition stabilizes and to adapt to potential changes in fluid needs.

This approach optimally balances the need for rapid resuscitation with the need to avoid excessive fluid administration later on, which could lead to complications such as pulmonary edema.

Other options do not align with established guidelines; for example, administering all fluids within the first hour may lead to rapid overloading, while equal distribution over 24 hours ignores the urgent needs during the initial stages of care. Only delivering fluids when vital signs
