Flashcards in Abnormal Labor Deck (42):
1

Protracted active phase dilatation is when the mother has regular contractions and the rate of cervical dilation is

<1.5cm per hour

2

A diagnosis of arrest disorder can be made when the mother is in active phase with at least how much cervical dilation?

3-4cm

3

Criteria for arrest of 2nd stage of labor is how many hours with and without epidural?

>4 hours no progress with epid
>3 hours no progress without epid

4

Prolonged latent phase in an nulli and multigravid (0-3cm)

>20 hours in nulli
>14 hours in multi

5

Intervention for prolonged latent phase

Bed rest
Oxytocin

6

Prolonged deceleration phase (8-10cm) is how many hours in a nulli and multigravid?

>3 hours nulli
>1 hour multi

7

Secondary arrest in dilatation (max slope) occurs after

>2 hours

8

Arrest of descent happens if the fetus is in what level for more than 1 hour?

Station +1 onwards

9

Criteria for arrest disorder:
Beyond latent phase
Uterine contraction >200 Montevideo units for ___ hours without cervical change

2 hours

10

Conditions for CS:
At least ___hours of adequate contractions and minimum of ___hours of oxytocin augmentation if contraction pattern cannot be achieved

4 hours
6 hours

11

This describes the number of contractions x average uterine pressure in a 10 min strip

Montevideo unit

12

Inappropriate leg positioning in stirrups in prolonged second stage may be die to compression of what nerve?

Common peroneal nerve

13

Zavanelli maneuver requires restoring the fetal head back into this position

Occiput anterior or posterior

14

Shoulder dystocia happens when the anterior shoulder becomes wedged behind this structure in the pelvis

Symphysis pubis

15

Head to body delivery time of more than ____ seconds indicates shoulder dystocia

>60 seconds

16

Lifting the legs in McRobert's maneuver increases

AP diameter

17

This maneuver attemps anterior shoulder disimpaction by applying suprapubic pressure over posterior aspect of anterior shoulder

Mazzanti

18

This maneuver attemps anterior shoulder disimpaction by inserting 2 fingers vaginally and pushing the posterior shoulder toward the chest

Rubin

19

This maneuver puts 2 fingers on the anterior aspect of the posterior shoulder to rotate obliquely

Wood corkscrew

20

This maneuver puts patient into all fours, grasp posterior arm of the fetus, sweeps against chest and deliver

Gaskin

21

Which maneuver is applied to reduce the nuchal arm in breech delivery

Loveset maneuver

22

This maneuver in breech delivery is where the assistant applies suprapubic pressure to favor flexion and engagement of fetal head

18 months

24

One of the most common causes for indicated preterm birth
