what is version? when is version done (indications)?
turning of the fetus, can either be done externally or internally
what are the indications for an external version?
baby is breech, transverse, or in oblique lay (diagonal, the fetus’ shoulder in pelvis)
must be one baby
amniotic fluid amount is enough
reactive NST (FHR and movement is reassuring)
what meds are given before external version?what is the purpose of these meds?
Tocolytics are given — either terbutaline or magnesium sulfate
these are given to relax the uterus so that it doesn’t contract
what nursing interventions done before and after external version?
get labs (CBC)
ultrasound has been done to check fetal position, umbilical cord and placenta placement, and enough amniotic fluid is present
IV is put in, in case of an emergency or fluids need to be given
nurse should monitor baby and mother before and after procedure
position pt supine, trendelenburg, pillow behind the knees, and gel is available to decrease friction
give RhoGam to prevent incompatibility issues and decrease risk of maternal-fetal hemorrhage
list tocolytics
magnesium sulfate
terbutaline
indomethacin
nifedipine
internal version occurs when?
only in twin deliveries, with the second twin’s birth
what are contraindications for external version?
ROM (rupture of membranes)
nuchal cord (umbilical cord around the neck)
C/S indicated
suspected IUGR (could indicate placental abnormalities)
multiple gestation (more than one fetus)
amniotic fluid abnormalities
maternal problems like HTN, Gestational diabetes, and preeclampsia
what are indications for labor induction?
post-term gestation (greater than 40 wks)
macrosomia (baby greaser than 8lbs and 13 oz)
pre-eclampsia and pregnancy induced HTN
Diabetes Mellitus
Fetal Compromise — IUGR and Oligo
fetal demise
non-reassuring FHR
PROM
Chorioamnionitis —infection in the uterine lining from GBS or MRSA
maternal compromise
what is Bishop score used for?
calculate readiness for labor by checking if the cervix is favorable, done by checking cervical dilation, effacement, consistency, position, and the station of the fetal presenting part
for a pt who is 38 wks a bishop score of eight means successful induction
the higher score = successful labor induction
what are contraindications to labor induction?
placenta previa (can’t have a vaginal delivery since the placenta either covers the entire cervix or part of it - C/S required)
transverse lie
prolapsed cord
fetal distress
classical uterine scar — increases risk of uterine rupture
active genital herpes
CPD (baby cannot fit though pelvis)
what are the methods used for labor induction?
cervical ripening - using outside agents to prepare the cervix for delivery
Stripping membrane
sexual intercourse
herbs — i.e. evening primrose oil
what are some examples of cervical ripening methods for labor induction?
prostaglandin gel — releases prostaglandins that softens the cervix and stimulates contractions
misoprostol (cytotec) - inserted either vaginally, sublingual, or oral
transcervical catheter — mechanical dilation occurs with a foley catheter — pressure on the cervix causes prostaglandins to release and begin contractions
what is “stripping membrane”? how does it induce labor?
stimulates labor within 24-48 hours
finger swept in cervical os to strip amniotic membranes — though to release prostaglandins
may cause bloody discharge and painful
what are indications for labor augmentation?
prolonged labor
no progress
dysfunctional labor (problem with one of the 3P’s
CPD (cephalopelvic disproportion)
if not CPD then - AROM or oxytocin may be required
what are nursing interventions for labor augmentation?
monitor maternal VS
FHR and NST
have pt void every 2 hours
keep pt calm, educate, and stay with couple
NPO
AROM
Artificial rupture of membranes — amniotomy done
Amniotomy
shortens labor by using amnihook
what should be assessed before amniotomy?
check that pt is 2cm dilated
know dilation and station of fetus before performing
THIS IS ALL DONE BY DOING A sterile vaginal exam BEFORE
what are nursing interventions after amniotomy?
take temperature every 2 hours
check FHR before and after — are they tolerating the labor well?
have pt be on bed rest
assess fluid — using COAT
what are risks of amniotomy?
increased risk for infection and trauma to fetus
prolapsed cord risk or compression of cord
no research shown to confirm that is does quicken labor
amnioinfusion
instillation of LR or NS into uterus
why is amnioinfusion done?
oligohydramnios (low amount of amniotic fluid present)
to dilute meconium and decrease fetal aspiration of meconium (with NS)
decrease risk of fetal chord compression
how do you administer oxytocin (Pitocin)?
given with a separate IV pump
30 units with 500 mL of IV fluid***
begin with 1-2 mL/hr and increase by 1-2 mU every 30 minutes if needed until good contraction pattern**
monitor contraction pattern and FHR
FOR POSTPARTUM: 10 units IM or IV push or IV fluid rate of 100 mL/hr of 30 units/500mL bag
what are nursing interventions when administering oxytocin (pitocin)
monitor fetus (is fetus tolerating labor?)
monitor maternal BP
monitor contractions
assess and adjust dose accordingly
what are the contraindications of oxytocin/pitocin?
increased BP in pt
distressed fetus
prolapsed cord
(BASICALLY ANY pt THAT NEEDS C/S)
what should nurse do if fetal distress is noticed during oxytocin administration?
lay pt on left side
stop oxytocin (pitocin)
increase IV fluids
administer oxygen at 8-10L per nonrebreather mask
may admin turbutaline subq
what are the nursing cares for an episiotomy and laceration?
ensure perineal hygiene is being performed —> educate pt to wipe from front to back, pat to dry, use peribottle (rinsing with water)
ice packs or sitz baths
change pad frequently — it could become breeding ground for bacteria
increase water intake, fiber, and take stool softeners
give pain meds (analgesics)
educate on when sexual intercourse can resume
why is laceration better than episiotomy?
quicker healing time than episiotomy
decreased sexual dysfunction
less anal sphincter damage
what types of patients are at high risk for forceps-assisted delivery?
nullipara (first time mom)
maternal age greater than 35
short women < 4ft 11in)
pregnancy wt gain > 35 lbs
postdate gestation = bigger fetus

abdominal scrub
meds
fetal monitoring
education: pt will be given anesthesia - either general, spinal, or epidural
they will feel pulling or tugging but it should be painless

what should be prepared before epidural?
signed informed consent on file
IV bolus given
what is the biggest disadvantage for epidural?
maternal hypotension
caused when peripheral vasodilation occurs - decreases venous return - decreases cardiac output - and lowers BP/causes SOB/chest pressure reported
what are S&S of maternal hypotension?
BP drops
SOB
chest pressure
what should be done if maternal hypotension occurs?
give another fluid bolus
what are contraindications for epidural?
