Yes, they got the IV in on the first stick. It was somewhat traumatic, but it could have been worse. Once they got him sedated and into the MRI he started wheezing and his vitals dropped. They were worried enough about his breathing that they stopped the MRI and woke him up.
We have to wait until his wheezing and cough stop, then reschedule the MRI, and start all over from scratch. Poor kid. He’s a trooper.
