Which type of fluid is typically given first in treating DKA?

In the management of Diabetic Ketoacidosis (DKA), the primary goal is to restore intravascular volume and improve renal perfusion, which is crucial for the clearance of ketones and glucose. The first line of fluid resuscitation in DKA typically involves administering isotonic saline, specifically 0.9% Normal saline.

This type of fluid is effective in expanding the extracellular fluid volume, correcting hypovolemia, and addressing dehydration, which are common in DKA due to osmotic diuresis from hyperglycemia. By providing an isotonic solution, normal saline helps to stabilize blood pressure and improve perfusion to the organs.

After the initial fluid resuscitation, additional considerations such as electrolyte management and the reintroduction of dextrose may come into play, particularly once blood glucose levels begin to drop significantly. However, during the initial treatment phase, 0.9% Normal saline is the most appropriate choice to ensure immediate volume replacement and stabilization of the patient's condition.
