Happy 2010 ?!?

Wow, what a year it has been! And it's only January 11th!! My dear little Lexi was just released from the hospital yesterday. She was admitted with DKA and tachycardia! It all happened so fast. From being perfectly fine to being admitted in the PICU!
She woke up on Thursday morning with a stomach ache. Knowing it could be high blood sugars, I had her check that first. 470. Wow! We right away bolused her for the high blood sugar and she took a bath. After her bath we checked again and 411. She vomited and we checked for ketones. HIGH! I knew right away we were dealing with DKA so she got dressed and we headed to the ER.
She was taken back right away and put on an IV, blood drawn and hear monitor. Her heart was racing in the 170's and she was laying down! I can't explain what I felt seeing that heart monitor go and go and go. The doctors had no idea why her heart was racing so much. Her blood results came back, and just like I suspected, DKA.
The hospital we were at had no PICU, so they scheduled an air lift to a hospital about an hour away with a PICU. I shuddered, not knowing what the next days would bring. Diabetes and a fast hear rate are two separate scary things. I was so scared and didn't know what to do.
She was in tachycardia for over 24 hours. They pumped her with IV fluids, thinking she was dehydrated and it was to no avail. She was given tylenol for a slight fever and it did not bring down the heart rate either. They STILL have no idea what happened. Has anyone every experience such a thing? It did eventually come down, but it's scary to me not knowing what caused it. I wish I had definite answers.
So I say, Happy 2010?!? I do hope it gets better...... it just has to!
