Just spent the evening in the ER. About 6:45 pm, he came to me with drool bubbles and his mouth at an odd angle. I thought he was choking on something. He got his drink, and it all ran out and he was jumping up and down, not able to close his mouth. I looked and could see nothing and his mouth was at a strange angle. We went to ER--his Oxygen level was like 82 so they took him directly back with oxygen. They came in and did a breathing treatment and took x-rays of chest and soft tissue in mouth. He was fine by this time and not really anything to see. Within 20 minutes, it all started over. Mouth with huge drool bubbles and his neck off to one side. The doctor(his primary care doctor was on call) came in and tried to move his neck over, nothing. He was shaking all over, slurred speech, tongue hanging out...and his mouth started to lock in a clenched state. This lasted about 15 minutes and was over. After about 30 minutes, it began again. They drew blood and his Depakote level was 102. He had 750mg at 8:20 am, and then 250mg at 12:30 pm. We did not give any night medications tonight at all. The doctor thought about Ativan to calm him, but I said NO WAY as it totally does the opposite. We are now home and just watching for any signs of breathing difficulties. So...until then.
