Mastering Cervical Exams: Accurate Fetal Station Assessment for Nurses

Question
This is not a pregnancy question about myself. This is to benefit me at work. I am a nurse of 5yrs. I recently left pediatrics to go to L&D. I absolutely love it. The nurses are having a hard time explaining how to determine the "station" of the baby. I'm fairly comfortable with determining dilation and effacement, but I'm having a hard time with the station. I've looked in every book I think might be helpful, but I still can't find the information I need. Can you please offer this advise or at least tell me where I might find it. Thank you.

Answer
We determone "station" by measuring the number of centimeters above or below the cervical spines during an internal exam.  Sometimes it is difficult to palpate the spines, but with the passage of time and many exams, you will be able to see how deep your fingers have to reach into the vagina to feel the presenting part.  When the presenting part is at the level of the spines, we call it "zero" station. If it is above that level, it is either -1,-2, or floating (-3). If it is below that level, it is either +1,+2, or +3(crowning). I guarantee that after awhile, you will suddenly get a feel for it.  Good Luck. I believe that L&D nurses are the kindest, most dedicated, and knowledgeable individuals I have ever met.
