Yes, but from what I've read about that, the medical personnel involved in handling a patient in a medically induced coma go to great lengths to prevent brain damage - ie. proper ventilation, circulatory support, those sorts of things.
You added stuff while I was replying.
Also TV generally shows a coma patient waking up with few deficits and no physical issues. Being bed-ridden for any length of time creates
serious physical degradation.
Sometime ago I recall hearing that a coma is also defined as lasting no more than 14 days or so. After that it's called a 'persistent vegetative state' and people don't generally recover from that - their brains are jello.
That's why I recommend looking at the Glasgow Scale for anyone planning to knock Lois out for any length of time.
