Flashcards in Ch 13-14 Labor & Birth Processes Deck (45)
Factors Influencing Labor Initiation
- Uterine stretch
- Progesterone withdrawal- pregnancy mx hormone
uterus gets crampy and then goes into labor
- Increased oxytocin sensitivity
- body’s natural hormone that is UTERUS specific and makes it contract
- nipple stimulation is #1 method to increase oxytocin
Pro: When done in moderation, it can get labor going
Con: no control on amount of oxytocin you produce. Can hyperstimulate uterus
- Increased release of prostaglandins
- softens cervix and thins it out, effaces
Premonitory signs of labor
increased energy (nesting)
bloody show (mucus plug)
spontaenous rupture of membranes (water break)
Stronger over time
UC’s continue despite position
5 min apart x2 hours
No increase in intensity
Localized pain (front)
UC’s come and go with position changes
Passenger - this is where position of baby is covered
Position - most confusing - of the MOTHER, not of fetus
Psyche (psychological response)
what can you ask mom to do if baby is LOT?
If diamond is closer to anterior and triangle is posterior, it is ...
If diamond is L and triangle is R, it is ...
most desirable position & presentation
the relation of the long axis (spine) of the fetus to the long axis (spine) of the mother
(longitudinal vs transverse)
which is most subjective
is true cephalopelvic disproportion common or rare?
who would have problems w/ cervical dilation?
those w/ a leap
anyone w/ HPV w/ tissue removal
anyone w/ D&C or D&E (scar tissue)
what is a good indication that someone's pelvic msks are strong?
opening of cervix
entering of the biparietal diameter (widest) into the pelvic inlet.
The baby's head (presenting part) moves deep into the pelvic cavity and is commonly called lightening. – greatest at deceleration phase of 1st stage and during 2nd stage of labor
occurs during descent, brought about by resistance felt by the baby’s head against the soft tissues of the pelvis. Smallest diameter of the baby’s head presents into the pelvis
head reaches pelvic floor & rotates to accommodate for changes in diameter of the pelvis. Baby must move from sideways to facing posterior
head passes through pelvis at nape of neck and there is a rest. Occurs as head, face, and chin are born
after baby’s head comes out, it sucks back in a little & rotates to face down
last big relieving push which results in baby
Involuntary uterine contractions
Augment the primary powers
responsible for effacement and dilation
divided into frequency
not letting the patient push so that primary powers can work baby down further into pelvis
effective for only 1 hr
longer the labor, the greater the risk of infx.
