Cx: C/2-3/-1????

yeonoh1 yeonoh1 (New) New

Could anyone let me know what 'Cx: C/2-3/-1' stands for?

I am a little bit confused.

Cx = Cervix


2-3= dilated 2-3cm

-1= station

Am I right???

I have no idea! I would think "C" would mean "closed," but if she's 2-3 cms, that negates that thought. I can't think of a word to describe someone's effacement that would start with "C."

'c' could be complete?????

To me "complete" refers to dilation still, not effacement. Meaning fully dilated. Although in my neck of the woods, we say "fully," never "complete." I only found out that was a thing when a doc came to us from Texas. Where did you see this written? On a board on an L&D unit?

This is from my EFM online review course.

Another example is here.

" A 29 yearold G2P1 patient was admittedfor spontaneous labor with complaints of moderate pain, Cervicla exam results inlcude: C/5/1 vertex....

Yeah I have no idea, that's super weird.

You sure it's 5, not 50?

Effacement is always the second number, and it's always expressed in percentages (unless it's "thick").

Unless this is a weird shorthand and they just drop the zero? So 2-3 really means 20-30? No idea. It's not standard.

Although, it wouldn't be 50% effaced and C/completely dilated.

So yeah, I have no idea either.

when I chart contractions, I chart cx.. I dont use that for the cervix.

It should be

dialated: in centimeters from 1-10 or could be FT for fingertip.

Effacement: how thin the cervix is becoming and in percentage

Station: position of baby in relation to the ischial spines. -3 to +3 is what is usually noted or ballotable meaning the babys head isnt engaged into the pelvis.

Sounds like someone may be charting against policy if no one recognizes this form of notation. Check your policy manual carefully or ask your unit manager for clarification on how to correctly chart these observations.

Before I realized this was an L&D thread I was thinking cervical spine, for part of it.

I'm at a loss. No clue.


Has 20 years experience.

I read it as: c= complete= 100% effaced (some of my docs call 100% effaced 'complete'), 2-3 cms dilated, -1 station. I would not chart it that way and that is not how it is charted in my geographical location. I would chart that cervix check as 2-3/100/-1.

Where I work we also use "C" as completely effaced. So on the board, it can look like: C/C/+1 for example, meaning Completely dilated and completely effaced, and +1 station.

Sometimes we'll even say, "She's complete, complete, +1"

We have a doc who's originally from NYC (I'm in CA) who also says "She's fully"....all meaning the same thing. I think sometimes it's a part of the country thing.
