We have great news! The MRI came back clear so they don't think there is any brain damage. The Lumbar Puncture (spinal tap) is also clear (no signs of infections or bacteria). The medicine used to put him under has now worn off and he is showing signs of physical improvement. His pupils are dilating better and he is not clenching his mouth shut.
They did find out that his PICC line was growing bacteria and that is why they suspect that he has had a low grade fever for the last couple of days. They have removed it and put in an IV in his hand for liquids and blood draws. It took them 3 tries to successfully put the IV in, which was sad to watch. However, during the process he yelled out loud for the first time in 2 days and is being more responsive. He still doesn't seem to recognize family members. Speech therapy is coming to evaluate him today and he is still having respiratory treatments for his lungs.
We are grateful for the improvements. Suzanne, one of the doctors, told me that we will watch him overnight and his team will meet in the morning to discuss his changes. Thank you again for all your love and concern, we love you all!
