Maternity Part 2 Flashcards
excessive or pernicious vomiting during pregnancy leading to dehydration and starvation
hyperemesis gravidarum
what would you give through an IV for a pt with hyperemesis gravidarum
LR bc has electrolytes
what is a possible etiology of hyperemesis gravidarum
possible bc of increase level of HcG, thyroid dysfunction, disruption of GI motility, increase estrogen level
S/Sx of hyperemesis gravidarum
N & V , intractable
Tx for hyperemesis gravidarum
hydration (3000mL within 24 hours
Rx (Zofran, phenegran)
nutritional supplements (ensure)
monitor for keytones
cervix is unable to support the increasing weight of the pregnancy, results in painless dilation of cervical os without labor or contractions, associated with repeated 2nd trimester abortion )16-28 weeks)
incompetent cervix
predisposing factors for incompetent cervix
prior traumatic delivery, Hx of D&C, conization, cauterization, mother of pregnant women who took DES, anomaly of uterus or cervix
Dx of incompetent cervix
Hx, examination (vag exam), U/S
Tx for incompetent cervix
cerclage or purse string suture, inserted in cervix to prevent preterm cervical dilation and pregnancy loss, tightened and secured anteriorly
spontaneous ROM prior to onset of labor
premature rupture of membranes
*gestational age doesn’t matter
spontaneous ROM: latent period
time from ROM to onset of labor (usually within 24 hours)
spontaneous ROM: interval period
time from ROM to birth
Etiology of PROM
unknown, contributing factors: infection, Esp. UTI, polyhydramnious, trauma, mult gestation
what maternal risks can happen because of PROM
INFECTION
chorioamnionitis: inflammation of membranes
endometritis: postpartum infection of endometrial lining
what neonatal risks can happen because of PROM
RDS, sepsis
Management of PROM
Abx, bedrest, CBC, fetal monitoring, Temp Q4 hours, daily WBC, corticosteroids and amniocentesis prn, L/S ratio to check lung maturity
occurrence of regular uterine contractions at less than 10 minute intervals after 20 weeks but prior to 37 completed weeks gestation, it is the greatest single problem in OB
premature labor
what Rx can you give to stop labot
Tocolytics
what do you need to do to identify those pts at risk for premature labor
gather Hx, cervical length and funneling, ffn (fetal bibronectin), Sx of preterm labor
funneling
greater than 50% funneling before 25 weeks has a 80% risk of preterm delivery
extracellular matrix protein of fetal membranes binds placenta and membranes to decidua, found before 20 weeks and after 34 weeks
fetal fibronectin
if there is fetal fibronectin present between 20 and 34 weeks this is what
abnormal = risk for premature labor
preterm labor Sx
abd tightness, menstrual cramping, back discomfort (comes and goes), pelvic pressure, intestinal cramping
what can the pt do to decrease the risk for preterm labor
regular PN care, refrain from sexual intercourse, empty bladder Q2 hours, curtail work activities, allow for rest, left lateral position, maintain adequate nutrition and hydration
