I had somewhere between 16-20 ultrasounds. I had a high risk pregnancy and they were keeping a close eye on the baby. Each ultrasound cost around $700 plus the costs from the doctor and lab for reading the results. Luckily our insurance picked up the cost after we paid $2500 out of pocket. Even with all that expense my daughter was totally worth it and is perfect.
Part of the difficulty in answering this question is that depth and cause of coma may vary, and memory is impaired during coma so people might hear but not be able to recall what they hear. In brief: Hard to know. It is hard to know if people in a coma can hear you.
We can hear you talk to us. Hello, I was in a coma for 2 months following an automobile crash. A man hit me and my 3 children head on while going 95mph. I only remember glimpses of the wreck, not the flight to the ER or the ER itself, altho I was told I was making jokes. At first they put me into a drug induced coma while my legs and left arm were in steel cages with rods drilled into me. Then I slipped into my own coma only to was on 9/11/01 then slip back in for 2 more weeks. I had nightmares.
