Q

Four passenger problems that can cause dysfunctional labor. Which is counter-indicated with vaginal delivery?

A
  • Fetal anomalies
  • Cephalopelvic disproportion (CPD)**
  • Malpresentation
  • Suboptimal fetal position

CPD is counterindicated with vaginal delivery

Q

Six risks of turning a breech

A
  • Fetal distress
  • Rupture of membranes

Q

When is a breech baby turned?

A

Done between 36-37 weeks

18
Q

Exercises to encourage spontaneous version

A

Pelvic lifts

19
Q

What is Friedman’s Classification?

A

A way of monitoring progress in terms of cervical dilation and fetal descent

20
Q

What categories are represented on Friedman’s curve? (5)

A
  • Precipitous labor
  • Multipara
  • Nullipara
  • Secondary Arrest
  • Prolonged latent phase
21
Q

What is precipitous labor?

A

Total labor process is complete in less than 3 hours

22
Q

Precipitous labor is associated with…

A
  • Increased risk of maternal and fetal complications

- Cocaine use

23
Q

Complications of precipitous labor

  • Mom (2)
  • Fetus (1)
A
  • Mom: Tearing, Hemorrhage

- Fetus: Intercranial bleeds

24
Q

“Trial of Labor” : Def

A

Allowance of a “reasonable period” of spontaneous active labor to determine safety

25
Indications of Trial of Labor (3)
* Maternal pelvis is a questionable size/shape * Vaginal birth after cesarean (VBAC) * Abnormal presentation
26
Induction of Labor (def)
Contractions initiated before spontaneous onset
27
Two methods of induction of labor
* Pitocin | * Amniotomy
28
When is success of IOL greater?
If Cervix is "favorable"
29
Bischop Scoring Method (def) | What does a higher score indicate?
Evaluating the "favorability" of a cervix | Likelihood that an induction of labor will result in a vaginal birth. Higher score = more likely to succeed
30
What five components does the Bishop scale measure?
* Dilation * Effacement * Station * Cervical consistency * Cervical position
31
Name five components of a top-scoring bishop scale
* Dilation of 5-6 * Effacement of 80% * +1 station * Soft cervix * Anterior position
32
Chemical agents applied to "ripen" cervix
* Prostaglandins (prepidil, Cervidil) | * Misoprostol (Cytotec)
33
Three results of chemical cervical ripening
* Higher success of induction * Lower doses of pitocin * Shorter induction times
34
Pitocin: Methods of administration
* Intravenous titration * IM **Antepartum pitocin must ALWAYS be a pump
35
What must you monitor with pitocin?
Monitor FHR and contraction patterns Q15
36
Indications of IOL (7)
``` Unsuitable environment: • Suspected fetal jeopardy: Is the baby better out or in? • Chorioamnionitis: Amniotic infection • Maternal Medical Problems • PIH: Pregnancy Induced Hypertension ``` Pre/Post term • PROM • Post-term: The uterus is a union worker Death • Fetal Demise (FD)
37
What does PIH stand for?
Pregnancy Induced Hypertension
38
Risks of IOL (5)
* Fetal distress * Failed induction * Uterine rupture * Water intoxication * Hyperstimulation with Pitocin
39
Hyperstimulation with pitocin (def)
Very frequent, intense contractions with non-assuring FHR
40
Hyperstimulation with pitocin: • CTX • Resting time • Uterine resting tone
* CTX Q2m x >90 seconds * Resting time less than 30 seconds * Uterine resting tone >20mmHg
41
What is an augmentation of labor? | • Two methods
An intervention after labor begins spontaneously, but CTX stop or abnormal labor is diagnosed. * Pitocin * Amniotomy
