Q

4 stages of labor and small summary of what happens

A
  1. Stage 1 : onset of true labor to cervical dilation complete, (latent + active phase )
  2. Stage 2 : complete dilating of cervix to delivery of infant
  3. Stage 3 : Delivary of infant to delivery of placenta

Q

Stage 1 : Latent stage vs active stage

A
  1. Latent = slow cervical dilations, intermittent slow getting closer together
  2. Active = when dilating is fast beginning around 6cm = admit pt for labor at this time**

= first stage takes 6hr-18hr(1st baby), 2hr-10hr(second baby)

Q

Epidural vs no epidural second stage time

A

Pushing takes 1 hour longer with epidural, however can prevent pushing before cervix is all the way dialated

  1. 2 hours = first baby no epidural
  2. 3 hours = 1st + epidural
  3. 1 hour = 2nd no epidural
  4. 2 hours = 2nd + epidural

Q

Cardinal movements is what

A

Every Descent Family In England Eats Eggs

  1. Engagement = zero station
  2. Descent = uterine contraction maternal valsalva efforts
  3. Flexion = chin to chest (OA from occipitofrontal to suboccipitobregmatic)
  4. Internal Rotation = at ischial spines, fetal enters pelvis and rotates posterior or anterior to pubic symphysis
  5. Extension = when largest D of baby head is encircled by vagina , station 5+ = head come out by extension and rotation to align with chest
  6. External Rotation = head align itself with fetal back and shoulders
  7. Expulsion = ant shoulder delivered then post shoulder and rest of body

Q

Management of second stage

  1. How to position mom
  2. With each contraction
  3. Monitoring
A

1 .Avoid flat on back (dorsal litho to my position = can compress BF to baby

  1. Bearing down : with each contraction : hold breath and expulsion effort
  2. every 15min (uncomplicated), every 5min (complicated)
22
Q

Modified Ritgen Maneuver

A

Helping baby’s head come out by supporting the perineum and prevent tears
= one hand on face to extend baby head (by perineum) and other hand on occiput to control delivery

23
Q

What to do before delivering rest of body ones head is out

A

Nuchal cord check to make sure its not around neck

24
Q

Perineal Lacerations

1st degree, 2nd degree, 3rd degree, 4th degree

A
  1. Superficial , vaginal mucosa and Erin eat skin
  2. Extend to muscles of perineal body
    3 .extend completely through perineal body into anterior sphincter (however not into anal mucosa)
  3. Extends through perineal body into anal mucosa
25
Q

When head is delivered what can you do

A

Bulb suction oral cavity and nose to clear airway

26
Q

How to deliver :
1. Ant shoulders
2. Post shoulders
Repairing any tears is what stage

A
  1. Using head down
  2. Elevating head (can cause perineal tear
    2nd stage
27
Q

Episiotomy

A

Precutting perineum if needed (do if there is high risk of tear or if you think here will be upward tear happening)
= cute Midline down if possible
= can cause easier 3rd and 4th degree laceration

28
Q

Placenta should be derived by and average time

A

30min if longer = Retained placenta

Average = 2min-10min

29
Q

Placental separation classic signs + what not to do

A
  1. Gush of blood
  2. Umbilical cord lengthen
  3. uterus fundus raises up + changes from discoid to globular shape
    = DONT PULL cord until classic signs are noted (uterine inversion)
    = apply counterpressure between symphysis and uterus fundus (push down above pubic symphysis so fundus is above your hand holding it in place)
30
Q

Management of 3rd stage

A

Look for lacerations, repair them, monitor uterine bleeding when placenta comes out, inspect placenta

31
Q

4th stage what do you do

A
  1. Fundus check and vaginal bleeding check = press on fundus to stimulate it for contraction to lower postpartum bleeding
  2. Vitals check
  3. 1% Have postpartum hemorrhage (uterine atony** uterine did not contract well= boggy cant contract down, retained placenta, infection from unprepared tear)
32
Q

If pt is at term however is not delivering what do you do

A

Don’t wait until after 42weeks,

  1. Induced delivery (ripen and soften cervix)
  2. Augment (pitocin or rupture them)
33
Q

Reasons to induce a pregnant pt (some ex, dont need to memorize)

A
  1. Fetal demise
  2. Gestational. HTN
  3. PROM
  4. Oligohydraminos
  5. Abrupt placentae
34
Q

Who should not have vaginal delivery

A
  1. Fetal unstable, acute fetal distress
  2. Placenta Previn, vasa Previn
  3. Previous C-section, transfundal uterine surgery (myomectomy) **
  4. HIV, HSV
35
Q

BISHOP Score

A

How successful will the dilation be

  1. Dilation
  2. Effacement
  3. Station
  4. Cervical consistency (soft is good)
  5. Cervical Postition (Anterior is good)

(Under 6 = bad (if still needed go to C-section), over 8 you can go to induction)

36
Q

3 things to give to cause cervical ripening

A
  1. Cervidil (Dinoprostone)
  2. Cytotec (Misoprostol)
  3. Mechanical Dilator ( Foley bulb catheter / cooks catheter inflating tp 30cc-80cc, Laminar Japonicum of rods places and swelling)
37
Q

Cervidil (Dinoprostone)

  1. what
  2. How
  3. Fact
A
  1. PGE 2
  2. Vaginal insertion (can be removed if needed or not tolerated)
  3. NOT in pt with previous C-section (Safer however more expensive)
38
Q

Cytotec (Misoprostol)

  1. what
  2. How
  3. Fact
A
  1. PGE 1
  2. Orally of vagina dissolves (cant be removed if need)
  3. Not for previous C section pts (cheaper and usually in OBGYN)
39
Q

How to induce contractions

  1. What
  2. How to give and how much
  3. How long to effect
A

PITOCIN (oxytocin)

  1. 1-30mu dose, start at 2mu/min, increase by 2mu if needed (IV)
  2. 3-5 min to cause uterine response
40
Q

Complications in Pitocin

A
  1. Uterine Tachysystole : 5 ore more contractions in 10min
  2. Antidiuretic (has ADH, and oxytocin) : increase water given (stop contractions), can lead to severe water intoxication or dehydration
  3. Uterine Muscle fatigue : prolonged used (can cause postpartum hemorrhage from uterine atony)
41
Q

OB anesthesia can effect

A

Fetal BF, fetal hypotension, (give fluids and hydrate before anesthesia)
= EPHEDRINE given to restore BF and BP in uterine

42
Q

Regional Anesthetic refers to

A

T10 and down anesthesia

43
Q

No pharmocology anesthesia you can do

A
  1. Lamaze
  2. Emotional support
  3. Back massage
  4. Hydrotherapy
  5. Acupuncture
44
Q

Parenteral anesthesia (IV) + ex + what it does + risks

A
  1. Morphine, Fentanyl, Meperidine, Nalbuphine
  2. Early stages of labor (more visceral pain, less intense)
    = very low labor pain relief
    = opioids cross placenta + cant be given at all in Dceles
45
Q

Regional local anesthesia (epidural + Spinal)

A

T8-T10 and below
BUPIVICAINE or LIDOCAINE + fentanyl
1. Epidural (most effective, between L2/3, L3/4, or L4/5, catheter placed over needle) = can be done during c-section if you go vaginal to C-section
2. Spinal (single shot, 30–250min, C-section usually)

46
Q

Regional Anesthesia benefits

A
  1. Highly effective
  2. Alert and awake mother
  3. Can remember experience
  4. Rarely need local anesthesia for tear repairs
47
Q

Regional Anesthesia side effects + contraindications

A
  1. Spinal headache, hypotension, fever, abscess, spinal hematoma
  2. Bacterimia, heparin use in 12hr, coagulopathy,skin infection, increased intracranial P
48
Q

Local anesthesia used

A

For repair tears

  1. Lidocaine (20-40min), can cause cardiac arrhythmia, seizures, hypotension)
  2. Puedendal Block (in women with no regional anesthesia, can cause hematoma or infection at injection site)
49
Q

General Anesthesia used and what risk and what you need to do, when you do this

A

Propofol

  1. LOC of mother, need to help with respiration, 16 times higher mortality of mother
  2. Can cross placenta and can effect fetal respiration
  3. Emergency needing rapid delivery or failed regional anesthesia
50
Q

How do you put in an epidural

A

Between L2 and L5

Inject through intersegmental ligament into EPIDURAL space to Squeeze SUBARACHNOID (Subdural) space (where nerves pass)
