TRUE CONJUGATE

10.5 - 11 cm

Transverse or interspinous

10.5cm

Anteroposterior diameter through the level of ischial spines

11.5cm

1. DIAGONAL CONJUGATE

12.5 - 13 cm

AMNIOTIC FLUID EMBOLISM

Amniotic fluid is forced into an open maternal uterine flood sinus through some defect in the membranes or after partial premature separation of the placenta

CILINICAL PELVIMETRY

Determination of adequacy of the inlet reaching the promontory of the scarum

PLACENTA VELAMENTOSA

Distance away from the attachment of the cord and the vessels

Interspinous diameter / Bispinous diameter

Engagement of the fetal head

result of shoulder dystocia

Erb's palsy damage of c5-c6

OBSTETRIC CONJUGATE

Estimated subtracting 1.5- 2ccm to diagonal conjugation

Posterior sagittal

From the midpoint of the interspinous line to the same point in sacrum 5 cm

RETAINED PLACENTA

If the placenta is undelivered at 30 minutes, it should be considered to be 'retained'

CORD PROLAPSE

In a prolapse, the umbilical cord drops (prolapses) through the open cervix into the vaginal ahead of the baby.

SHOULDER DYSTOCIA

Inability to deliver a baby's shoulders after its head has emerged.

PRECIPITATE DELIVERY

Labor and delivery that is completed in <3 hours due to multiparity or following oxytocin administration or amniotomy

PLACENTA CIRCUMVALLATA

Membranes appear to be attached internally to the placental edge, and on the periphery there is a ring of thick whitish tissue which is in fact a fold of infarcted chorion

UTERINE RUPTURE

Occurs when the uterus undergoes more straining than it is capable of sustaining

decidua

Placenta attaches to the uterus until labor, when it separates with the help of contractions

placenta percreta

Placental chorionic vili grow through the uterine myometrium and often adhere to abdominal structures (bladder or intestine)

Placenta accreta

Placental chorionic villi adheres to the superficial layer of the uterine myometrium

Placenta increta

Placental chorionic villi invade deeply into the uterine myometrium

PLACENTA ACRETA

Rare cause of retained placenta

passageway

Refers to the route the fetus must travel from the uterus through the pelvis.

Preterm premature rupture of membrane

Rupture of membranes before onset of labor in pregnancies between 28-37 weeks

UTERINE INERTIA

Sluggishness of contractions

Premature rupture of membranes (PROM)

Spontaneous rupture of fetal membranes before onset of labor

INDUCED LABOR

Stages of labor and birth occurs due to chemical or mechanical means which is usually performed to save the mother or fetus from complications which may cause death

PLACENTA BIPARTITA

The placenta is partly divided into two lobes with connecting vessels

FORCEPS DELIVERY

Use of metal instruments to extract the fetus from the birth canal, when at +3 / +4 and sagittal suture line is in an AP position in relation to the outlet

Cesarean Section

birth through a surgical incision on the abdomen

Ethyl alcohol

blocks release of Oxytocin

Symphysiotomy

cutting the pubic symphysis

atropine sulfate

for preoperative medication care C/S

cleidotomy

fracturing the fetal clavicle

Android

heat shape, male pelvis

Uterine rupture

management: Hysterectomy

Ritodrine

muscle relaxant per orem

Anthropoid

oval in shape. Transverse diameter is narrow. A-P is longer. Ape pelvis

Induced labor

oxytocin(pitocin)

zavanelli

returning the fetal head to the pelvis for delivery of the baby via cesarean section

"high" or "floating

terms used to denote unengaged presenting part

Gynecoid

the true female pelvis

Platypelloid

wide but flat, kidney-shaped

DISPROPORTION

• Is a state wherein there is a discrepancy, between the size of the fetus and that of the pelvis • Due to an average-sized baby in a woman with a small pelvis or a normal pelvis with a big baby or due to a combination of these factors

BATTLEDORE PLACENTA

● Sometimes the cord has a marginal instead of a central incision ● This has no clinical significance

Placenta membranacea

● Unduly large and thin ● Not only develops from chorionic frondosum but chorionic levae so whole of ovum is practically covered

PLACENTA SUCCENTURIATA

● Vascular connection between main and accessory lobes ● Accessory lobe is retained and manually removed
