Our ED protocol is to start with 2 boluses NS to try and get the BG down. Then we reassess. If the patient is still hyperglycemic or in DKA (an anion gap is more diagnostic than the BG...you can have a BG of 220 and be in DKA) then we start the drip. We use a computerized program and when/if the patient eats, we plug the number of carbs into the program and it adjusts the drip. We check BG hourly and once the patient reaches 200, we continue the drip but switch them over to D51/2NS until the BG is down around 140. Then we start basal insulin and d/c the drip. It works well, you just have to stay on top of the BG checks, but the computer program alarms. You also have to watch their K+ because depending on the patient it can be really high or really low initially and once you start the insulin, it will change over several hours. Also, it doesn't make sense to me that a doctor wouldn't be concerned about an elevated BG because that is what causes the acidosis. If you can correct that - you'll correct the DKA.
