physiological changes before labor (only the names)
physiological changes before labor - lightening
fetal descent into the pelvic brim
physiological changes before labor - Braxton-Hicks contractions
benign contraction that do not result in cervical dilation. They routinely start to increase in frequency towards the end of the pregnancy
physiological changes before labor - Bloody show
blood-tinged mucus from vagina that is released with cervical effacement
stage of labor - only names
stage of labor - stage 1 (when and duration)
onset of labor –> full cervical dilation
primigravid: 6-18 h
multipara: 2-10 h
stage of labor - latent phase (when and duration)
onset of labor –> 4 cm dilation
primigravid: 6-7 h
multipara: 4-5 h
stage of labor - active phase (when and duration)
4 cm dilation –> full dilation (10 cm)
primigravid: 1 cm per hour
multipara: 1.2 cm per hour
stage of labor - stage 2 (when and duration)
full dilation of cervix and mother wants to push –> delivery of neonate
primigravid: 30 mins - 3 h
multipara: 5-30 mins
stage of labor - stage 3 (when and duration)
delivery of neonate –> delivery of placenta
30 mins
stage of labor - stage 1 (monitoring)
monitor: 1. maternal BP and Pulse
2. electronic fetal monitor (fetal HR and uterine contractions)
3. examine cervix to monitor the progression of labor for
a. cervical dilation
b. effacement
c. station: where the fetus’s fead is located in relationship to pelvis (measured -3 through +3)
stage of labor - stage 2 - the progression of this stage is determined by
the rate of fetal head descent
stage of labor - stage 2 - steps
stage of labor - stage 2 - steps - engagement
fetal head enters the pelvis occiput first
stage of labor - stage 2 - steps - descent
stage of labor - stage 2 - steps - flexion
fetal head flexion
stage of labor - stage 2 - steps - internal rotation
stage of labor - stage 2 - steps - extension
occurs so that the head can pass through vagina (oriented forward and upward)
stage of labor - stage 2 - steps - external rotation
stage of labor - stage 2 - steps - delivery of anterior shoulder
gentle downward pressure on the fetal head will aid in delivery of anterior shoulder
stage of labor - stage 2 - steps - delivery of posterior shoulder
stage of labor - stage 3 - definition
immediately after delivery, inspect and repair lacerations of the vagina while waiting for placental separation
stage of labor - stage 3 - signs of placental separation
induction of labor - medications (only names)
