I had an interesting week last week. I was admitted to hospital day surgery for a minor procedure that I've had several times before. Nothing unusual going on for this procedure. Mid-procedure, I stopped breathing and heart rate dropped to 30's. Surgery was stopped and I ended up in ICU for 3 days, on a ventilator for two. After a week of tests, the docs are still puzzled by this event. I am now beginning a thorough outpatient workup by several specialists, including my neuro. Has anyone experienced anything like this and found it to be MS-related?
