Q

Version

A

Change fetal presentation

Contraindications: abnormal uterus shape, baby over 4000g, engagement of fetal head, nuchal cord

Risks: fetal hypoxia, abruptio placentae and immediate c-section if compromised

perform NST or BPP, after 37wks, administer tocolytic or RhoGAM if needed

107
Q

Operative vaginal birth

A

Forceps or vacuum extraction

Indications: exhaustion, inability to push effectively, non reassuring FHR patterns, failure of presenting part to rotate and descend

Contraindications: severe fetal compromise, maternal CHF and pulmonary edema, high fetal station and disproportionate fetus size to maternal pelvis

108
Q

Chignon

A

Scalp edema that often forms under the suction cup of a vacuum extractor

109
Q

3 Classifications for operative vaginal delivery

A

Outlet operative vaginal delivery- fetal head is at perineum, with the scalp visible at vaginal opening

Low operative vaginal delivery- fetal head between +2 and +3 (passed ischial spine)

Midpelvis operative vaginal delivery- fetal head between 0 and +2 station

110
Q

Median or midline episiotomy

A

Advantages: minimal blood loss, neat healing with little scarring, less postpartum pain

Disadvantages: an added laceration may extend the median episiotomy into the anal sphincter, limited enlargement of the vaginal opening due to anal sphincter

111
Q

Mediolateral episiotomy

A

Advantages: more enlargement of the vaginal opening (more room for the baby to come out), little risk that the episiotomy will extend to the anus

Disadvantages: more blood loss, increased postpartum pain, more scarring and irregularity in the healed scar, prolonged dyspareunia (painful intercourse)

112
Q

Why is the rate of c-sections increasing

A
  • women having their first baby more like to do c-section
  • first baby induced greater risk for c-section
  • repeat c-sections more common
  • more common in older pregnant woman
  • breech position
  • higher maternal requests
113
Q

Placenta accreta

A

Abnormal adherence of the placenta to the uterine wall, often along the previous incision area

114
Q

Indications and risks of cesarean section

A

Indications- dystocia, cephalopelvic disproportion, hypertension, active genital herpes, previous uterine surgical procedures, prolapsed cord, breech, abruptio placentae

Risks- infection, hemorrhage, UTI, thromboembolism, paralytic ileus, atelectasis

115
Q

Why is Bicitra administered before cesarean section

A

Given to reduce gastric acidity

116
Q

Pfannenstiel skin incision

A

Transverse or “bikini” cut

Advantages: less visibility when healed and the pubic hair grows back, less chance of dehiscence or formation of a hernia

Disadvantages: less visualization of the uterus, can’t be done as quickly (emergency cesarean), can’t easily be extended to give greater operative exposure, re-entry at a subsequent cesarean may require more time

117
Q

McRoberts maneuver

A

To relieve dystocia the woman flexes her thighs sharply against her abdomen , which straightens the pelvic curve somewhat

118
Q

Gynecoid shaped pelvis

A
  • most common
  • round, cylindric shape throughout. Wide pubic arch (90 degrees or greater)
  • prognosis for vaginal birth: good
119
Q

Anthropoid shaped pelvis

A
  • long, narrow oval. Anteroposterior diameter is longer than transverse diameter. Narrow pubic arch
  • prognosis for vaginal birth: more favorable than android or platypelloid pelvic shape. Fetus may be born in occiput posterior position
120
Q

Android shaped pelvis

A
  • heart or triangular-shaped inlet. Narrow diameters throughout. Narrow pubic arch
  • prognosis for vaginal birth: poor
121
Q

Platypelloid shaped pelvis

A
  • flattened wide, short oval. Transverse diameter wide, but anteroposterior diameter short. Wide pubic arch
  • prognosis for vaginal birth: poor
  • not ideal for vaginal delivery= cesarean
122
Q

Precipitate labor vs precipitate birth

A

Labor- birth occurs within 3 hours of its onset

Birth- when a trained attendant is not present to assist

123
Q

Medication used to accelerate fetal lung maturity

A

Betamethasone (celestone) - 12mg IM. Corticosteroid used to stimulate surfactant production BEFORE delivery.

Dexamethosone - 6mg IM q12h x 4 doses

124
Q

Fetal fibronectin

A

A protein present in fetal tissue that correlates with presence of onset of labor

*positive fFN mid pregnancy could mean maternal or fetal infection

125
Q

Prolapsed cord

A

Occult prolapse- cord compressed between fetus and pelvis and can’t be seen or felt during vaginal exam

Cord prolapsed infront of fetal head

Complete cord prolapse- cord can be seen protruding from the vagina

Interventions: reposition, give oxygen, don’t touch cord, keep presenting part elevated
