Definitely take the lot off hairwise. The scar is only at the top of the hair but they stick a sticky plaster dressing over the cut and you don't want it to be stuck to the lower bit of hair when they remove it (OUCH!).
Ask for the IV to be put in the side of your wrist not the back of your hand - much less uncomfortable and it gives you greater freedom of movement. They should put numbing cream on 15-20 mins or so before they put the IV in. Ask for that if they try to do it without.
Ask for a pre-med. I didn't want to be stressed or anxious during the op so I asked for one. The anesthetist said "that's not necessary and may affect your baby" in a very snotty way. I told the nurse this and she was outraged and said "of course you can have a pre-med, it does no harm at all!" and promptly got me a pill. I was sooooooooooo chilled out in the theatre - not doped up just very relaxed and lucid and pleasingly warm and tingling. Don't know what they gave me but I'm looking forward to my next c-section in Dec so I can get some more! Ditto the morphine!
Make sure you have no jewellery on you and no coloured polish on fingers or toes.
I was very worried about the catheter being inserted. But I needn't have been. They put it in after the spinal so you don;t feel a thing or even notice it is there. There is no pain involved in it at all. The nurse will take it out when you get up for the first time in the morning and you don't even feel it.
Don't panic when they give you the spinal block. As they do it your leg might jump - its perfectly normal and doesn't mean they've hit a nerve or anything! No one warned me though and it freaked me out.
Also occasionally you will start to feel pale and sick immediately after the spinal. Lots of people get an immdiate drop in blood pressure. Just tell the anesthetist you feel sick and she will bring your BP back up - takes seconds. You may dry heave but you'll have been fasting so will have nothing in you to throw up. This is all VERY normal so again, don't panic.
The incision is made very low down and only in the top layer of tissue, the muscles are not cut these days, the surgeon will gently move them out of the way to get to your uterus which he will make another cut in to get the baby out. This technique is much less hard on the body and you shouldn't get much, if any, bruising and minimal healing time required.
You won't feel any of this. In fact you'll feel warm, comfortable and a little high - in a good way.
I didn't want goop covered baby put on my bare skin so they wrapped her in a towel and gave her to H who held her next to my head. That was perfect.
When you are in the theatre they drape you modestly (top half plus legs and pubic area) so the only bit of you to be exposed is the actual area where they are making the incision. Well they did for me anyway. If this is something you particularly want you can ask for it. I didn't like the idea of being naked and immobile on the slab so that worked for me very well.
Take laculose in with you in case they don't precribe it automatically (for the constipation).
BIG pants - seriously the bigger the better and black if poss.
Take a small cushion in with you. When you first stand up you press it to your scar aea and it helps a lot with the discomfort.
Take BLACK slippers with you - blood drips don't look so good (remember you'll be having the equivalent of a very heavy period for a few days afterwards)
Get up and move around as soon as you can - take a walk down the hallways with your H. You'll be nervous about it but the more you move the less likely you are to get constipated or gassy (which is NOT good). You'll heal quicker and have less pain too.
MAKE SURE YOU KEEP TRACK OF YOUR MEDICATION. The nurses get pretty busy with other women in labour and people being demanding. Ask them how long the medication works and when your next dose is due then set an alarm on your phone to remind you. Push the button and say "My next shot is due now". This is especially true if its night time. You do not want to wake up and find you've gone over by a few hours because "they didn;t want to wake you".
Immediately you feel you can move your feet ask for pain meds (say you're beginning to feel discomfort). No it won't actually HURT at that point but the idea is to prevent the pain not try and get it under control after its taken hold. They may try to give you IV paracetamol first before offering you a morphine shot. Take the paracetamol but within 5 minutes ask for the morphine - paracetamol does bugger all.
If I were you I'd definitely request ibruprofen based painkillers rather than paracetamol in conjunction with the morphine and for after the morphine isn't necessary (day 2/3 onwards). Propanol is excellent and can be bought OTC. Paracetamol did nothing for me.
