So i had a new onset DKA kid yesterday... we started a iv bolus sent of a bmp among other labs. his sodium was 126....corrected for his hyperglycemia..his sodium is about 137. the computer calculated his gap to be 9 using 126 as the sodium. when calculating the gap, should you use the 126 or the corrected sodium of 137? according to the computer his gap was already closed BEFORE we even started the insulin. Using the corrected Sodium, his gap is more like 21. I'm thinking the latter. what do you guys think?
