"i was placed under general anesthesia for surgery.  in recovery the tube placed in my throat for inhalation had not been removed before i woke up.   i was in a panic.  i was screaming in my head that i can suffocating and yet in reality no one could hear me.  i had been given dilaudid along with a few other medications.  later in my hospital room i where i was again given dilaudid.  i was not able to get anyone&#039;s attention, but felt that if i fell asleep i would never wake up.  either the experience or the medication caused me to have to concentrate on just breathing.  for pain it was great, but for breathing it seems like a nightmare."
