Hi, my son had a GA when he was 13 months. I felt ok about it as I work as an ODP and assisting anaesthetists is my day-to-day job.
He was not pleased about being starved but quite enjoyed the tiny hospital gown! I carried him down to theatre accompanied by a nurse and there was a special paediatric area with toys etc where he pottered about whilst the ODP did the final checks (allergies etc). We then went into theatre and DS was allowed to take his teddy in to play with, I sat on a chair with DS on my knee and the anaesthetist 'gassed him down'. This basically consists of him putting the mask with O2 and anaesthetic gasses on the child's face and the fact that the child usually takes a big breath in in order to complain makes them go off pretty quickly.
I was then asked to put DS on the operating table and ushered out of the room. This is when the staff will put a little Venflon in the child's hand and get them ready for the op.
With DS the ward gave me a beeper and I had coffee in the hospital cafe and they beeped me when he was in recovery, the op took about 1 1/2 hrs I think. The paed nurse took me straight to the recovery room and we were taken back up to the ward on his bed. He was absolutely silent until he saw me then started screaming blue murder, so I sat on the bed with him on my knee having a cuddle and porters pushed us back.
They took the Venflon out on the ward as soon as he fancied some water and toast and wasn't in any pain. He was fully recovered from the anaesthetic v soon afterward and we were discharged about 2hrs after the op.
Children seem to be pretty resilient on the whole about the process and the staff do fuss over the tots and look after them very carefully. I really think it's more distressing for the parents, so ask your anaesthetist, nurse, ODP lots of questions so you know what's going to happen.
