I had an emergency c-section in March (an HBAC that was not meant to be) and it was actually a lot less scary than my emergency c-section with my son (which was in the US). After it was decided I needed a section, they had me put on a gown and then took me and my husband back to get the spinal done in a room adjacent to the surgical theater.
They put an IV in my hand (which hurt like crap and took forever because I have difficult veins), then did the local anesthetic shot in my back, then the spinal. Both were painful and unpleasant sensations, but nothing to get scared about really. Then they had me lay down on this table and watched my blood pressure as they tilted the table all over the place to balance out the spinal. They also kept pushing some other medication to help raise my blood pressure because the spinal was making it drop pretty freaky low. After they got my BP under control and made sure I was sufficiently numb (I could wiggle one of my toes, but that's it, and the same was true for when I had my spinal with my son's birth), which was about up to my boobs.
Then we wheeled into the surgical theater and they put on some music
From there on out, it was basically the anesthetist making small talk and jokes to my husband and I until they said she was out. After that, they took her over to the baby warmer and started stimulating her because she had a really weak cry that scared the crap out of me. After a few minutes (that felt like a lifetime), she finally started really using her lungs and they brought her to my husband to hold beside my face so I could see and touch her. They let them stay with me while they closed, then loosened my gown so we could do skin-to-skin contact on the way to the recovery ward. There was never a need for her to actually leave my sight, which was a great change to how they do it in the US.
The maternity ward was pretty miserable-- about 10 women to the room, just curtains separating. They had me start walking around while pushing the baby in her little bassinet on wheels the next morning and took the catheter out that evening. You're very stiff and sore at first, but walking is the best way to speed up recovery. Just take it slow. I found that when I was walking on my own just around, holding a pillow against my stomach made it a little easier and less like my guts would come out, haha. Anyway, it was quite noisy and uncomfortable, so I was anxious to get out and left AMA a day early.
My best advice would be to bring:
-socks and comfortable slippers
-several easy to put on nightgowns that easily allow boob access for breastfeeding
-big ugly underwear you don't mind ruining
-maternity pads, diapers, wipes
-nursing pads (washable cloth ones are my favorite)
-a couple different sizes of clothes for baby since you won't know what'll fit for sure
-your camera, phone, and chargers for both
