Hi, @shwetha – I'd like to add my welcome to Mayo Clinic Connect and express my condolences you have been through all of this with your young son. As a mother myself, I can't imagine having a child who is happy and healthy and suddenly takes a dramatic turn, starting with a massive cardiac arrest.
I'd like to bring into this discussion @jakedduck1@crstyday40@ssaygi@lakelifelady@mmaryemc for any thoughts they may have for you and your 4-year-old son who has anoxic ischemic encephalopathy, has ongoing seizure activity and is in a minimally conscious state. They may have input from some of their own experiences about keeping him awake and using medications which are failing to control his seizure activity or should sedating him and waiting for his brain to heal.
Will you share more about the hyperbaric oxygen therapy your son will be having? How are you feeling about these infusions?
