16
Q

what must be done before starting pit

A
  • reactive NST
  • vaginal exam

17
Q

why are pit patients at risk for postpartum hemorrhage

A

uterus is overstimulated for so long that it stops reacting to the drug
- as a result the uterus doesnt contract anymore after birth and bleed

Q

what a volutrol

A

- prevents bolus (bolus would cause constant contraction that would dec perfusion to the baby)

Q

what is an amnioinfusion

A

warmed NS or LR that is placed into uterus via IUPC
- fluid should still be leaking out of mother, if not SVE and lift baby’s head to release

Q

why do you have an amnioinfusion

A
  • replacement of lost or absence amniotic fluid
  • repetitive variable decels with inc intensity (adding fluid prevents cord clamp)
  • meconium dilution

Q

what is forceps assisted birth used for

A
  • mother’s with heart disease
  • acute pulm edema or pulm compromise

  • prolonged second stage
  • exhaustion
  • non reassuring fetal strip

25
what are the types of forceps
mid forceps: fetal head engaged low forceps: fetal head at 2+ outlet forceps: fetal head at perineum
26
when do you use pull with forceps and vacuum
when the mother is contracting and pushing
27
maternal risks when use forceps
lacerations extension of episiotomy anal sphincter injury perineal edema
28
neonatal risks when use forceps
bruising, edema caput succedaneum or cephalhematoma transient facial paralysis cerebral hemorrhage fractures elevated bilirubin levels
29
nursing management for forcep births
- explain procedure - monitor contractions - push during contractions - document length of time forceps used *only used when indicated
30
what is vacuum assisted birth
suction cup placed on fetal occiput - pull when mom contracts and pushes - fetus should descent with each contraction - document : pressure applied, pressure off, vacuum off (time used)
31
indications for a c/s
- complete placenta previa - cephalopelvic disproportion - placental abruption - active genital herpes - cord prolapse - failure to progress - tumor obstructing birth canal - breech presentation - previous c/s - congenital abnormalities - bad fetal status
32
types of c/s incisions
skin incision and muscle incisions are different - skin: transverse (most common) and vertical - muscle: low transverse, classical, low vertical
33
which is the best c/s incision
low transverse - classical and low vertical inc risk for rupture later
34
nursing care before c/s
- epidural - bolus - pepcid and reglan and bicitra (neutralizes stomach acid) - monitor VS - FHR - foley - prepare abdomen and perineum - all ppl and equipment
35
nursing care during c/s
- position: wedge to left tilt prior to delivery - instrument count - time out - document: incision, delivery of infant, APGARS, AROM, placenta extracted, EBL (est. blood loss), meds given
36
what is supine hypotension and how to treat it
mom lays on back and baby squished vena cava - place wedge on R hip to lie on L side
37
nursing care after c/s
- newborn care - VS 15 mins - surgical dressing - palpate fundus - check lochia - I and Os - admin oxy and pain meds
38
what is a vbac
vaginal birth after c/s
39
what is a tolac
trial of labor after c/s - classified as this until the mom gives birth
40
vbac qualifications
- low transverse uterine incision - adequate pelvis - no other uterine scars or rupture - HCP and anesthesia
41
referred pain
contractions felt else where in the body
42
visceral pain
slow, dull, achy pain
43
somatic pain
sharp and localized - burning, tearing pain - transition or push pain
44
systemic analgesia
provides maximum pain relief at minimum risk for the mother or fetus - all meds cross placental barrier - fetal liver and kidneys can metabolize meds so only admin when necessary
45
butorphanol tartrate
opioid - onset 30-60 - mom: drowsiness, dizziness, fainting, hypotension - fetus: resp depression
46
nalbuphine hydrochloride
opioid - onset 15-20mins - mom: resp depression, drowsiness - fetus: resp depression - higher doses don't indicate inc risk of depression *dont give to women with substance abuse problems
47
meperidine
opioid - mom: resp depression, constipation, dizziness, itching - fetus: neurobehavioral depression, resp acidosis * not reversed by naloxone *
48
fentanyl
short acting opiate - IV immediate response - IM 5-7 mins - mom: hypotension, N, V, resp depression - fetus: some neurobehavioral depression * short half life and rapidly crosses placenta*
49
naloxone
opioid reversal agent - if mother had substance abuse problems, giving naloxone will inc risk for wdrawal seizures
50
regional anesthesia
temporary and reversible loss of sensation - prevent initiation and transmission of nerve impulses for pain control
51
disadvantages or epidural
- maternal hypotension - post delivery back pain - meningitis - cardiac arrest - vertigo
52
difference between epidural and spinal anesthesia
epidural is constant medication into epidural space while spinal anesthesia is an injection and no catheter remains
53
nursing management prior to epidural
- maternal and fetal status - assess labor process - IV with warmed LR - get into position
54
what position does a woman need to be in for an epidural
- chin to chest to round out back - nurse should put hands on shoulder in support
55
what is the biggest thing you need to assess for after an epidural
bp for hypotension
56
how do you correct hypotension post epidural
- fluid bolus - ephedrine will inc BP - oxygen non rebreather
57
pudendal block
perineal anesthesia used during second stage of labor and episiotomy repair
58
advantages of pudendal block
ease of administration (to access nerve) absence of maternal hypotension
59
disadvantage of pudendal block
urge to bear down may be decreased - will need to push longer
60
general anesthesia
emergent deliveries low platelet count scheduled c/s delivery and unable to place spinal (scoliosis)
61
cricoid pressure
diminished chance of aspiration during placement of endotracheal tube for general anesthesia - press on cartilage to close until anesthesia tells you to lift
62
potential problems with anesthesia
- fetal resp depression - sore throat - higher risk of aspiration - inc risk of postpartum hemorrhage - less feeling of control - everyone misses birth
