The lie is either:. Longitudinallong axis of the fetus is aligned to the mother'sthis is the only NORMAL positionTransverselong axis of the fetus is perpendicular to that of the mother'sObliquelong axis of the fetus is 0-90 degrees (or 90-180 degrees) to that of the mother's. . Longitudinal. Longitudinal.
1. Leopold’s - Abdominal Palpation for Fetal Position
2. The lie is either: Longitudinal
long axis of the fetus is aligned to the mother’s
this is the only NORMAL position
long axis of the fetus is perpendicular to that of the mother’s
long axis of the fetus is 0-90 degrees (or 90-180 degrees) to that of the mother’s
4. The presentation is either: Vertex
head down in the pelvis
head is up in the uterine fundus and the buttock in the pelvis
5. Attitude Relationship of fetal parts to each other:
6. Denominator The denominator is a “letter” that represents the presenting fetal part
Used in the listing system
Acromion AC or Scapula SC
9. Flexed Vertex Presentation 8 Possibilities LOL
arms & legs flexed in the
arms flexed but legs
extended straight up over
one or both feet extended downward and may exit the birth canal first
12. Engagement Determined by the amount of head that is above or below the pelvic brim
This is usually done by dividing the head into ”fifths”
if the head is still palpable abdominally, it is “2/5” or less engaged
Stations of Presentation
13. Leopold’s Maneuver
Determine the position of the baby in utero
Determine the expected presentation during labor and delivery
14. Questions to ask yourself when performing the exam: Is the fundal height consistent with the fetal maturity?
Is the lie longitudinal, transverse or oblique?
Is the presentation cephalic or breech?
If cephalic, is the attitude vertex or facial?
What is the position of the denominator?
Is the vertex engaged?
15. Preparation Woman is supine, head slightly elevated and knees slightly flexed
Place a small rolled towel under her right hip
If the doctor is R handed, stand at the woman’s R side facing her for the first 3 steps, then turn and face her feet for the last step (L handed, left side).
16. First Maneuver What part is in the fundus?
Facing the mother, palpate the fundus with both hands
Assess for shape, size, consistency and mobility
Fetal head: firm, hard, and round
Moves independently of the rest
Detectable by ballotement
Buttocks/breech: softer and has bony prominences
Moves with the rest of the form
17. Second Maneuver Determine position of the back.
Still facing the mother, place both palms on the abdomen
Hold R hand still and with deep but gentle pressure, use L hand to feel for the firm, smooth back
Repeat using opposite hands
Once you’ve located the back, confirm your findings by palpating the fetal extremities on the opposite side (“lumpy”)
18. Third Maneuver Determine what part is lying
above the inlet.
Gently grasp just above symphisis pubis with the thumb and fingers of the R hand
Confirm presenting part (opposite of what’s in the fundus)
Head will feel firm
Buttocks will feel softer and irregular
If it’s not engaged, it may be gently pushed back and forth
Proceed to the 4th step if it’s not engaged…
19. Fourth Maneuver Flexed/Deflexed/Extended?
Turn to face the woman’s feet
Move fingers of both hands gently down the sides of the abdomen towards the pubis
Palpate for the cephalic prominence (vertex)
Prominence on the same side as the small parts suggests that the head is flexed (optimum)
Prominence on the same side as the back suggests that the head is extended
20. Intro to Using a Fetoscope
21. Fetal Monitoring Equipment
Fetal heart Rate (FHR) can be determined by use of:
Fetoscope or Leff scope
specifically designed instruments
22. Doppler Method Employs a continuous ultrasound
Can detect the fetal heart at 10-12 weeks’ gestation
Amplifiers allow both the practitioner and parents to hear
23. Fetoscope Has a band that fits against the head of the listener
makes handling of the instrument unnecessary
aids in bone conduction of sound
Can pick up the fetal heart rate at 17-19 weeks’ gestation
24. Fetoscope Fetal heart tones are best heard over the baby’s back
Used in conjunction with Leopold’s maneuver
Auscultation may be difficult if…
Mother is overweight
Placenta is in the front of the uterus
*Always easier in later stages of the pregnancy
25. Where will you hear the FHTs?
26. Preparation Let her empty her bladder
Be sure the room is quiet
Patient lies supine
If more than 28 weeks pregnant, place a small rolled towel under R hip
relieves pressure on abdominal aorta
27. Procedure Place the padded cone just above the pubic bone
Headpiece solid against the forehead
Exert slight pressure into the abdomen
Slowly rotate the cone 360 degrees, looking for the heart tones
Must be directed at the baby’s heart to hear FHT
If nothing is heard…
Move the instrument up toward the umbilicus 1cm and repeat
28. If you have not heard the heart tones when you reach a position half-way between the pubic bone and the umbilicus…
Move 1cm to the side of midline
Proceed back down to the pubic bone
If FHTs are still not heard…
Do the same on the other side
Again, move the cone 1 cm at a time and rotate the instrument 360 degrees at each new position
30. Fetal Heart Rate Count the FHTs for 15 seconds
Multiply by 4
( ) x 4 = ___ per minute
To be more accurate, you may want to take more than one 15 second “sample”
sleeping = slower HR
moving = faster HR
