…
risk factos for placenta accreta
low lying or ant. placenta
placena previa
prior c-sect, D&C
over 35 yo
treat placenta accreta
- hysterectomy after delivery
2. if refuse, ligate umbilical cord high and IV methotrexate
serum testing
15-21 weeks
AFP, bHCG, unconjugated estriol
downs syndrome lab levels
AFP low
unconjugated estriol low
bHCG high
edwards syndrome lab levels
AFP low
uncon estriol low
bHCG low
causes of postpartum hemorrhage
- uterine atony
- genital tract laceration (if supracervical–>atypical atony)
- if late, subinvolution of uterus
causes of intrauterine growth restriction
placenta problens
chromosome abnl
DM, HTN, kidney/lung disease
smoking
TORCH
risk factors for preterm ruptured membranes
low SES STD smoking multiparity hydramnios placental abruption cervical colonization cerclage
fetal fibronectin tests for
PPROM
tocolytics
mag sulfate terbutaline, ritodine (beta ag) nifedipine indomethacin 17 alpha hydroxyprogesterone
side effect of terbutaline, ritodine
pulm edema
side effect of indomethacin
oligohydramnios –> cord compression –> deceleration
contra for tocolytics
suspected placenta abruption
chorioamniotis effect on fetal HR
tachycardia
manage postpartum hemorrhage
- uterine massage and IV dilute oxytocin
- uterotonic agents + ergot alkyloids
- IVs, foley catheter, vitals, call for blood
- intrauterine balloon
- laparotomy (hysterectomy or ligate vessels)
sinusoidal HR indicative of
severe fetal anemia or asphyxia
increased AFP in screen indicates
neural tube defects wrong dates abd wall defects oligohydramniois fetal skin defect low maternal weight cystc hygroma
