Vaginal Examinations in Labour

How often one is offered

NICE's list of observations to record during the first stage of labour ends with this: "offer a 4-hourly vaginal examination ... or in response to the woman's wishes if there is concern about progress (after abdominal palpation and assessment of vaginal loss)".

Four-hourly is therefore the routine offer, not a maximum and not a rule. More often than that happens when there is a specific question to answer — has anything changed since the oxytocin started, is the cervix fully dilated before pushing, is a suspected cord presentation there. Less often than that happens when you decline, and that is a legitimate outcome rather than a problem to be managed.

Earlier in the guideline, NICE describes the same offer at the initial assessment: "in established labour, a vaginal examination may be helpful after a period of assessment, but is not always necessary." The phrase "not always necessary" is doing real work there.

What they are feeling for

NICE lists six things, and it is a longer list than the one number people expect:

• the station of the presenting part — how far down the baby is;
• the position of the presenting part — which way the baby is facing;
• the presence or absence of caput or moulding — swelling or shaping of the baby's head;
• cervical effacement — how thin the cervix has become;
• cervical dilatation — the centimetres;
• the presence or absence of membranes — whether the waters are intact.

Dilatation is one of six. A "no change" examination can still have found that the baby has rotated, or descended, or that the cervix has thinned — all of which are progress by any sensible definition, and all of which are worth asking about before you conclude that nothing has happened.

The recommendation about consent

NICE writes an unusually detailed instruction for this one procedure. When conducting a vaginal examination, the clinician should:

• "be sure that the examination is necessary and will add important information to the decision-making process";
• "recognise that a vaginal examination can be very distressing for a woman, especially if she is already in pain, highly anxious and in an unfamiliar environment";
• explain the reason for the examination and what will be involved;
• ensure the woman's informed consent, privacy, dignity and comfort;
• explain the findings sensitively, including any effect on the birth plan;
• "advise the woman that she can decline the examination before it starts, or ask to stop at any stage during the examination".

That final bullet is a positive duty to tell you. If nobody has said it to you, the guideline has not been followed, whether or not you would have declined.

Saying no, or not yet

Birthrights states the general principle in plain terms: you do not have to agree to a procedure "simply because they are standard in this particular hospital or birth centre", and you can change your mind at any point.

Declining does not leave a team blind. Labour can be assessed by watching the pattern and length of contractions, by abdominal palpation, by the appearance of the vaginal loss, by the sounds and behaviour of a woman in transition, and by listening to the baby's heartbeat. NICE's own transfer criteria are built mostly out of observations that require no internal examination at all.

What declining does change is certainty about dilatation, which matters most when a decision hangs on it — whether an epidural can be sited before pushing, whether oxytocin is doing anything, whether it is safe to push. Asking "what will this examination change about my care?" is the question that separates useful from routine.

If internal examinations are difficult for you

This is common and it is worth planning for rather than improvising. The RCOG's patient information on considering a caesarean names anxiety "about how you might react to vaginal examinations" among the legitimate reasons women raise birth options with their team, and says that if you are anxious about examinations "your healthcare professional may offer ways of caring for you in labour that may be more acceptable to you".

Things that can be written into your notes in advance: that you want to be asked each time rather than told; that you want to give a specific verbal go-ahead immediately before, not just at the start of a shift; that you want a particular word to mean stop; that you would prefer a female clinician; that you want the room cleared of anyone not essential; that you want to position yourself. The HSE's material on preparing for a positive birth experience encourages exactly this kind of specific advance conversation.

If you have experienced sexual violence, or have had female genital mutilation, or have vaginismus or chronic pelvic pain, saying so antenatally means the plan is made calmly rather than in the middle of a contraction. You do not have to explain why in order for the preference to be recorded.

Does it hurt?

No national body publishes an average pain score for a vaginal examination in labour, and anyone offering you a number is inventing it. NICE's own language is that it "can be very distressing", which is about as close to an official acknowledgement as exists.

What is known to help is practical: timing it between contractions where possible, being told before each step, and knowing you can stop it. NICE permits tap water for cleansing if it is needed, and asks for single-use gloves as standard.

Who does it, and where

A midwife usually, an obstetrician sometimes, and a student only with your explicit agreement. NICE asks staff to knock and wait before entering, to respect personal space and privacy, and to ask others to do the same — which covers who is standing in the room while an examination happens.

The NHS's description of the stages of labour notes that once labour is established your midwife will check on you from time to time to see how you are progressing. "From time to time" is the honest version. Four-hourly is the offer; what you accept is yours.
