• Location of FHT (foetal heart tones) with pinard or fetoscope; good for gauging descent. FHT early deceleration pattern will indicate resistance onto pelvic floor and therefore descent.
• 6cm = contraction pattern shifts, flushing over cheekbones.
• 8cm = hot/cold/trembly/irritable/nauseous. Contractions seem to not give her a break.
• Near full = increased pressure, vomits, breathing more ragged, ‘catch’ in breath, deeper, guttural moaning. FHT’s midline and low. Sacrum seems flat and full. Her energy will be acutely aware during contractions but she will retreat just as intensely between them. More show, spotting of fresh blood. Feels like pooing, membranes release
• Purple line that creeps up like a mercury thermometer from anus to top of bum crease. When it reaches the top, the woman is fully (increase in intrapelvic pressure affects veins in the sacrum).
• Vomiting and ROM (release of membranes) at the same time = 7 cm stretch
• Look at bottom of foot with the toes pointing up. The spot above the heel and in the center will tighten and release as the uterus contracts IF she is at least 5 cm.
• Fully = passing stool involuntarily, pouting of anus, instinctive bearing down begins at the beginning of the contraction and not at the height of it.
• The contracting uterus swells upwards as it pulls in the dilating cervix. Before a woman begins to dilate and is about at term, you can get about 5 fingerbreadths of measurement between the fundus and the tip of the breastbone (xyphoid). As she dilates, this measurement decreases at about 2 cms per fingerbreadth. I.e., 1 1/2 fingerbreadths between these two points would be equal to 7-8 cms. dilation. It's an old trick I learned several years ago. This really works but, like vaginal exams, it takes practice. Unlike vaginal exams, it's not out of the scope of practice as a doula to do this type of exam because it's not done internally and not "really" considered a clinical test.
• Abdominal signs: thin line or crease above/parallel to Symphysis Pubis. As baby descends and cervix opens, the line/crease becomes wider from side to side. Near transition = ¾ across. All the way across indicates that pushing is most likely imminent (bulk of baby’s shoulders closer to SP?)
• When she "pushes" spontaneously, does it begin at the very beginning of the sensation or is it just at the peak? If it is just at the peak, it is an indication that there is still some dilating to do. The woman will usually enter a deep trance state at this time. She is accessing her most rudimentary brain stem where the ancient knowledge of giving birth is stored. She must have quiet and dark to get to this essential place in the brain. She usually will close her eyes and should not be told to open them.
• Does she "push" (that is, instinctively grunt and bear down) with each sensation or with every other one? If some sensations don't have a pushing urge, there is still some dilating to do. Keep the room dark and quiet as above.
• Are you continuing to see "show"? Red show is a sign that the cervix is still dilating. Once dilation is complete the "show of blood" usually ceases while the head molding takes place. Don’t mistake another gush of blood which may be vaginal wall tears at the point that the head distends the perineum.
• Watch her rectum. The rectum will tell you a good deal about where the baby's forehead is located and how the dilation is going. If there is no rectal flaring or distention with the grunting, there is still more dilating to do. A dark red line extends straight up from the rectum between the bum cheeks when full dilation happens. To observe all this, of course, the mother must be in hands and knees or sidelying position.
