Which therapy is emphasized in the management of DKA to lower blood glucose levels?

The primary therapy emphasized in the management of diabetic ketoacidosis (DKA) to lower blood glucose levels is insulin therapy. In DKA, the body is unable to use glucose for energy due to a lack of insulin, leading to high blood sugar levels and the production of ketones, which contribute to acidosis. Administering insulin helps to reduce blood glucose levels by promoting its uptake into the cells and inhibiting ketogenesis in the liver. This is crucial because rapidly correcting hyperglycemia and stopping ketone production are key aspects of resolving DKA and preventing severe complications.

Other therapies, such as oral hypoglycemic agents, glucagon injections, and dietary restrictions, are not effective in managing acute DKA. Oral hypoglycemics are generally not suitable in acute settings where intravenous therapy is required. Glucagon injections would further increase blood glucose levels, which is contraindicated in this scenario. Dietary restrictions alone would not provide sufficient or immediate control over the high blood sugar levels seen in DKA. Therefore, insulin therapy stands out as the best and most effective approach to manage blood glucose levels in this condition.
