- undeliverable

Compound - Jack Benny Presentation

hand comes down along the head
1/700

Persisten O.P.

occiput posterior - usually mother's pelvis has a somewhat android she and it's easier for the head to go toward the back of the sacrum

Fetal Macrosoma

>4,500 g
as maternal nutrition gets worse, 5% of fetuses weigh at least 4,000 g

Birth Size

1. parents have a genetic influence on how big you are
2. maternal size has a special relationship to fetal size
3. birth order: babies tend to get bigger in a woman's subsequent pregnancies

*this is an obstetrical emergency - the baby can stop breathing, or can end up with nerve damage to the brachial plexus
- put direct pressure just behind the pubic bone w/ hand or fist & pop ou

Fetal Hydrocephalus

bigger than outlet
babies w/ abnormally large abdominal circumference - may actually be bigger than the head, which would make it difficult if not possible to deliver

Conjoined/Locked twins

one is breech and one is vertex, so they can't be extracted from their entanglement

Bony Pelvis

1. contraction problems - any contraction lessens the area in the pelvis
2. women w/ rickets - practically no space between the sacral promontory and back of the pubic symphysis
3. contraction of pelvic outlet, contraction of mid pelvis, any combo
4. skew

Soft Tissue Abnormalities
