I assume that your CS is planned.
Your consultant is a gigantic bellend of the highest order. His job is to stress the risks, but also put them into context so he doesn't scare you witless. If he has failed to do this, then he has failed in his job. His job isn't just about doing the 'technical bit' of birth, its also about catering to the emotional needs and fears of his patients.
Yes there are risks associated with CS. But these are much, much, much more likely to happen if you have an EMCS rather than an ELCS. Trouble is, this message is being inaccurately being conveyed by just about everyone. This includes, doctors, nurses, midwifes, government bodies, scientists. Basically a lot of people who should know better and should, having studied science and how to conduct a fair experience and compare results, have a fucking clue. Sadly they don't appear to.
If you read statistics and research on C-Sections, ELCS are almost always lumped together with the stats for EMCS. This is completely flawed methodology and is very meaningless. And yet it is widely accepted without question from all the above professionals.
The statistics for a planned ELCS should actually be dealt with separately, with EMCS being looked at either in isolation (where relevant) or as an outcome for a planned VB. You either plan for one or the other, you don't plan to have an EMCS.
There are also risks associated with having a VB... These are not always stressed, and they should be. Especially if you need an ELCS, because the risks of you having a VB will be higher. Why he is stressing the risks of the CS and not the benefits of it in your circumstances is beyond me. (Unless of course he is a gigantic bellend, which since we have already established thats what he is, thats a mute point). In your case, from what I tell from what you've said, you are having an ELCS for a clinical reason and not by your own choice. So keep focusing on that.
Second of all, if you want to put the risks into some sort of perspective, heres one for you. NICE updated their guidelines on CS a couple of years ago. They did this by looking at the risks associated with a planned VB (which includes when it goes wrong and ends up as a EMCS) and a planned CS.
Their conclusion, based on evidence of first time mothers, was that on balance there was such little difference between the two, that they felt it reasonable for woman who requested a CS to be granted one on request if they felt that was in their best interest. This is slightly flawed in, that it didn't look at the effect of women who have already had a child or wanted another child in the future (which is important to bare in mind and should be considered but still wasn't enough for NICE to put a cavat or consider this in their guidance) but the point was that it is regarded as SAFE and that there wasn't a clinical reason in most cases to refuse to do a ELCS.
Then lastly, a couple of the biggest factors about why ELCS are 'safer' are precisely because they are planned. They are booked in during working hours, when there are more staff available and more staff with experience available. Because they are routine there is less of a sense of urgency, so they don't have to rush to do it, so there are less errors made 'in the spur of the moment'. So for example, if you planned for a VB, you have no guarantee about when you will give birth or if you might need an EMCS anyway. In this situation you could end up giving birth in the early hours at the weekend when there may be no senior staff on duty and fewer staff full stop. They might rush to get the baby out and in the process, not take as much time and care as they would otherwise do so. So if things, god forbid, DO go wrong, then you should be reassured having an ELCS, that you have a better chance of having the very best care available than perhaps you would out of hours. (This is wrong, that this is the case, but it is a reality which does exist and has been proven in NHS data).
Oh and theres no danger of you being left alone in theatre when you are giving birth. So if you are anxious, you have someone there to talk you through it and answer your questions. There will definitely be someone there to reassure you and not off dealing with someone else in labour.
In short the relative risk is very, very small. But the consultant is more interested in covering his own arse, than how you feel about any of this.
Thats wrong.
I hope you find the reassurance you need on this thread, from someone, if not me.
Good luck!
