Which intravenous fluid is commonly used to treat DKA initially?

In the initial management of Diabetic Ketoacidosis (DKA), the administration of 0.9% NaCl, or normal saline, plays a critical role. The first step in treating DKA is addressing the patient's dehydration and restoring normal fluid balance. Normal saline is isotonic and effectively expands intravascular volume, which is crucial given that patients with DKA often present with significant hypovolemia due to osmotic diuresis and fluid losses.

Normal saline also provides essential sodium, which aids in restoring electrolyte balance in the body. After thorough rehydration with normal saline, medical providers typically monitor the patient’s blood glucose and electrolyte levels, making adjustments as necessary, including the introduction of insulin therapy and, if blood glucose levels drop sufficiently, transitioning to the administration of dextrose-containing fluids.

Other options, while they may serve specific roles in the clinical management of patients under various conditions, are not the preferred initial treatment for DKA. For example, 5% dextrose in water could inadvertently exacerbate hyperglycemia if given too early, as it contains glucose. Lactated Ringer's solution might not provide enough sodium for DKA management. Likewise, dextrose 10% in saline would also not be
