Flashcards in Abnormal Labor Deck (42):
Protracted active phase dilatation is when the mother has regular contractions and the rate of cervical dilation is
<1.5cm per hour
A diagnosis of arrest disorder can be made when the mother is in active phase with at least how much cervical dilation?
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
Prolonged latent phase in an nulli and multigravid (0-3cm)
>20 hours in nulli
>14 hours in multi
Intervention for prolonged latent phase
Prolonged deceleration phase (8-10cm) is how many hours in a nulli and multigravid?
>3 hours nulli
>1 hour multi
Secondary arrest in dilatation (max slope) occurs after
Arrest of descent happens if the fetus is in what level for more than 1 hour?
Station +1 onwards
Criteria for arrest disorder:
Beyond latent phase
Uterine contraction >200 Montevideo units for ___ hours without cervical change
Conditions for CS:
At least ___hours of adequate contractions and minimum of ___hours of oxytocin augmentation if contraction pattern cannot be achieved
This describes the number of contractions x average uterine pressure in a 10 min strip
Inappropriate leg positioning in stirrups in prolonged second stage may be die to compression of what nerve?
Common peroneal nerve
Zavanelli maneuver requires restoring the fetal head back into this position
Occiput anterior or posterior
Shoulder dystocia happens when the anterior shoulder becomes wedged behind this structure in the pelvis
Head to body delivery time of more than ____ seconds indicates shoulder dystocia
Lifting the legs in McRobert's maneuver increases
This maneuver attemps anterior shoulder disimpaction by applying suprapubic pressure over posterior aspect of anterior shoulder
This maneuver attemps anterior shoulder disimpaction by inserting 2 fingers vaginally and pushing the posterior shoulder toward the chest
This maneuver puts 2 fingers on the anterior aspect of the posterior shoulder to rotate obliquely
This maneuver puts patient into all fours, grasp posterior arm of the fetus, sweeps against chest and deliver
Which maneuver is applied to reduce the nuchal arm in breech delivery
This maneuver in breech delivery is where the assistant applies suprapubic pressure to favor flexion and engagement of fetal head
Intervals shorter than how many months between pregnancies have been associated with an increased risk for preterm birth?
One of the most common causes for indicated preterm birth
Indomethacin as tocolytic promotes this effect on the fetus
Premature closure of the ductus arteriosus
Neonate that has the function expected of a newborn at <37 weeks with underdeveloped organ functions
One of the contributing factors to preterm birth is a threatened abortion during this period
6-13 weeks AOG
Intervals LONGER than how many months between pregnancies have been associated with an increased risk for preterm birth?
Infection usually associated with preterm birth
Single most powerful predictor of preterm birth
One of the sonographic signs of preterm birth is shortening of cervix to less than 25mm at how many weeks AOG?
Loading dose of magnesium sulfate for preterm labor
4g slow IV push over 20 mins
Antidote for Magnesium Sulfate toxicity
Tocolytic agent of choice for preterm birth
Nifedipine 10mg Q6
Prophylactic cerclage is done during
10-12 weeks AOG
Corticosteroid can also be given for preterm birth during
24-34 weeks AOG
Only reliable indicator for chorioamnionitis
Criteria for chorioamnionitis include maternal fever plus one of the ff
Purulent or foul smelling discharg
Management of chorioamnionitis
Birth must be delayed for this amount of time after initiation of corticosteroid therapy to reduce rates of respiratory distress
24 hours after last dose
Reversible complication of indomethacin
