check for cord prolapse
Why does “stripping the membranes” help to stimulate uterine contractions?
This action releases a surge of prostaglandins in the maternal circulation proportionate to the size of the area stripped.
Can the severity of fetal distress be measured by the depth of decelerations (in a late deceleration pattern)?

Variable decelerations that quickly return to a normal baseline with avg variability are NOT associated with hypoxemia and acidosis.
Early decelerations are…
Thought to be caused by head compression. Associated with cervical dilation. Shape of FHT pattern reflects shape of Uterine contractions.
Late decelerations are…
Thought to be caused by uteroplacental insufficiency. Onset occurs late in the contraction and extends beyond the end of the contraction. May or may not occur with each contraction.

Thought to be caused by cord compression. Onset unpredictable and may not be related to contractions. Length varies from a few seconds to minutes.
VEAL CHOP
Variable – Cord compression
Early –Head compression
Accelerations– OK
Late – Placental insufficiency
Lambda FHT pattern
An acceleration followed immediately by a deceleration and occurring with Uterine contractions. Unknown clinical significance. Benign, not associated with low Apgar scores or adverse outcomes. Main concern is its potential for confusing it with other patterns that do require intervention

not a sign of fetal distress
CPD may be evidenced by…
A dysfunctional labor pattern, poorly flexed head, or an arrest of internal rotation and descent
Uterine dysfunction is a diagnosis made by observing…
A prolongation of any phase or stage of labor beyond its expected length. Identified by a lack of progress in cervical effacement or dilatation or in descent of the presenting part.
Hypotonic Uterine Dysfunction…
uterine contractions have a normal gradient pattern (greatest in the fundus, weakest in the lower uterine segment) but poor tone or intensity- too little pressure to dilate the cervix. Woman feels little pain, labor is prolonged.
Hypertonic Uterine Dysfunction…

What is the Pinard Maneuver?
Used in frank breech delivery to bring down the feet and legs, one at a time. The Pinard maneuver (pressure in the popliteal space of the knee, which results in external rotation of the thigh and flexion of the knee) assists delivery of the legs.
In a breech delivery, after you have maintained a hands off approach until the baby is born up to the umbilicus you now do two things:
Pull down a loop of the cord to prevent stress on its insertion, and place a warm towel around the baby from just below the umbilicus down.
