labor & delivery complications + PP care (14%) Flashcards
3 categories of dystocia
power (uterine ctx)
passenger (presentation/size of fetus)
passage (uterus/soft tissue abnormalities)
tx for shoulder dystocia
non-manipulative- 1st line- McRoberts (hip hyper flexion to inc pelvic opening)
manipulative- 2nd line- woods “corkscrew” (180 degree shoulder rotation)
c/s last resort
complications of shoulder deistic
erb’s palsy (brachial plexus injury)
esp in macrosomic, multiparity, gestational DM
what is the definition of PROM
water breaks <37wks
RFs for PROM
STIs
smoking
prior preterm delivery
multiple gestations
dx of PROM
sterile speculum exam- pooling of secretions
nitrazine paper test- blue if pH >6.5 (likely PROM)
fern test- crystallized estrogen + Fluid
US- AVOID DIGITAL EXAM
normal vaginal vs amniotic fluid pH
vaginal- 3.8-4.2
amniotic fluid- 7-7.3
tx of PROM
wait for spontaneous labor
monitor for chorio or endometritis
terbutaline/mag sulf to delay labor
definition of premature labor
regular uterine ctx + progressive cervical changes <37wks
what is the MC cause of perinatal mortality
premature labor
when is a pt definitely in PTL
dilated 3+cm
effaced 80%+
when is a pt likely in PTL
dilated 2-3cm
effaced <80%
when is a pt unlikely in PTL
dilated 2cm or less
effaced <80%
when should steroids be given to mom in PTL
if L:S ratio <2:1 or <34wk GA
betamethasone
when should tocolytics be used in PRL
if no chorio is present (no infxn)
give for 48h to delay until steroids work
