Labor and Delivery Flashcards
What hormonal changes occur during labor
increase in prostaglandins, estrogen, and oxytocin
What are Leopold’s Maneuver
Four palpitations of the fetus through the abdominal wall to deremine where the feturs lies, it's presentation, and position Fundal grip Umbilical grip Pawlick's grip Pelvic grip
Definitions of Lie, Presentation, and Position
Lie-relation of the long axis of the fetus with the maternal long axis
Presentation-determined by the presenting part (breech or cephalic)
Position-relation of the fetal presenting part to the right or the left
What are the 3 identifiable parts on a fetus’s skull to help determine what way the baby is facing
Sagittal suture
Anterior and posterior fontanel
7 cardinal movements of labor
Engagement Descent Flexion-chin meets chest Internal rotation-head rotates to look at coccyx Extension External rotation-after head is born Expulsion
First stage of labor (latent and active phases)
Latent-cervical effacement and early dilation; may take 12-18 hours; no complications and occurs at home
Active- rapid cervical dilation about 1cm/hr
Need to manage maternal vital signs, IV access, frequent voiding, pain management (analgesics and anesthetics), pelvic exams, contractions, fetal HR, rupture of membranes
Nonpharm pain options for labor
Cont labor support warm water baths intradermal water injections maternal movement and positioning touch and massage acupuncture
Pharm pain options for labor
Parenteral opiods
Epidural analgesia
paracervical block
nitrous oxide
Second stage of labor
voluntary maternal effort (pushing)
“laboring down”-delayed pushing, decrease hard labor and increase duration of second stage; start when pt feels the urge to push
Options to help with delivery: episiotomy (not common), spontaneous vaginal delivery, vacuum extractors
Third stage of labor
Signs of placental seperation (uterus rises in abdomen, gush of blood, lengthening of umbilical cord)
Active management of 3rd stage: early cord clamping, controlled cord traction, uterine massage, Pitocin, or manual removal
Evaluate placenta: two umbilical arteries, one umbilical vein, cotyledons, intact membraneN
Indications for c section delivery
failure to dilate or failure to descend are MC
Breastfeeding
do within 1 hour of delivery
recommended nutrition for first 4-6 months
Advantages: mom: decreased breast cancer, wt loss, attachment, quicker to amenorrhea
Baby: better immunity, decreased DM, GI illness, HTN
Cervical ripening/induction
dilators or French foley balloon
Misoprostol
Electronic fetal monitoring
Baseline FHR 110-160bpm
Variability: most reliable indicator of fetal status; suggests adequate fetal CNS oxygenation (absent, minimal, moderate, marked)
Accelerations: increase in FHR above baseline >15bpm x 15 sec; reassuring for fetal well being
Decelerations: Early (mirror image of contraction, not concerning)
variable (varies when slowing of FHR begins, abrupt fall and rapid return; most common deceleration seen)
late (slowing that begins after contraction starts, more ominous)
Category 1 EFM
normal, moderate variability, may have accelerations, but no decerlations
