Preeclampsia/eclampsia
- sxs occur after 20wks gestation; most often occurs near term but can be up to 6 weeks postpartum
- preeclampsia: HTN, edema, proteinuria (edemal no longer necessary for diagnosis)
- HELLP: presence of severe preeclampsia with addition of Hemolysis, Elevated Liver enzymes, and Low Platelets
- Eclampsia is severe preeclampsia with the addition of seizures

- severe preeclampsia or eclampsia is indication for prompt delivery regardless of gest age
Rh incompatibility
- when mom is Rh neg and fetus is Rh pos
- Rh immunoglobulin (RhoGam) administered at 28-29wks to all Rh neg moms. If baby found to be Rh pos after delivery, mother receives RhoGam again to protect for future preg.
- RhoGam should be administered at any event in which mom and fetal blood can mix (ectopic, SAM or TAB, CVS, amnio, trauma)
- If Ab develops in mom against baby, future baby risks severe anemia and death (fetal hydrops)
- dx: routine prenatal blood work, in sensitized preg, combo of coombs test, amnio, and US used to follow fetus for distriss or fetal hydrops
- tx: routine RhoGam admin. at 28wks and w/in 72hr of delivering Rh pos infant
Chlamydia
- Most common bacterial STD
- RF: lack of condom use, lower socioeconomic status, living in an urban area, having multiple sex partners
- most common in F 15-19, then 20-24
- independent risk factor for cervical cancer
- Sxs:
- men: dysuria, purulent urethral discharge, itching, scrotal pain and swelling, fever
- women: puruelnt urethral discharge, intermenstrual or post-coital bleeding, dysuria
- mucopurulent discharge from cervical os, friable cervix

- dx: US, continuous electronic monitoring of baby
- tx: monitor closely for spontaneous version
- external cephalic version
- indications: singleton breech, nonvertex second twin, woman in 36+ wk gest.
- contra: engagement of presenting part, marked oligohydram, placenta previa, uterine anomalies, nuchal cord, multiple gest., PROM, previous uterine surg, IUGR
- complications: placental abruption, uterine rupture, ROM with cord prolapse, amniotic fluid embolism, PTL, fetal distress, fetomaternal hemorrhage, fetal demise
- external cephalic version
shoulder dystocia
- inability to deliver shoulders after head has delivered
- RF: fetal macrosomia, GDM, hx shoulder dystocia in prior birth, prolonged 2nd stage labor, instrumental delivery
- sxs: any indications of macrosomia - gentle downward pressure on head fails to deliver anterior shoulder form behind pubic symphysis. Avoid continuing pressure to head to deliver as this is ineffective and can damage brachial plexus
- attempt maneuvers
- complications: erb palsy, postpartum hemorrhage and lacerations
- tx: hyperfexion of maternal hips (mcroberts maneuver), offer cesarean in future deliveries
- prevention: address hx of shoulder dystocia macrosomia by estimated fetal weight, DM, prolonged 2nd stage, instrumental delivery
- previous hx of dystocia places women at an increased risk dystocia in future preg
Fetal Distress
- generally believed that reduced baseline heart rate variability is single most reliable sign of fetal compromise
- sinusoidal: Fetal anemia from Rh-alloimmunization, fetal intracranial hemorrhage, severe asphyxia, fetomaternal hemorrhage, twin-twin tranfusion syndrome, or vasa previa
- early decelerations: normal head compression during uterine contractions (active labor) - in most cases, onset, nadir of decel, and recovery are coincident with beginning, peak, and end of contraction respectively
- late decels: uteroplacental insufficiency - decel occurs after the peak of contraction
- variable decels: umbilical cord compression -> fetal anoxia -> death - abrupt decrease in FHR; decrease in FHR is >/=15 bpm, lasting >/=15s, and <2min in duration
Prolapsed umbilical cord
- descent of umbilical cord into lower uterine segment where it may lie adjacent to presenting part (occult) or below presenting part (overt)
- complications: variable fetal heart rate decels during uterine contractions with prompt return of HR as contraction end
- Occult prolapse: cannot be palpated during pelvic exam
- tx: immediate pelvic exam, place patient in lateral sims or trendelenburg - if FHT return to norm, continue labor. Deliver O2 to mom and monitor FHR continuously. Rapid c-sec if compression cont.
- Overt prolapse: associated with ROM and displacement of umbilical cord into vagina
- RF: premi, abnl pres, occiput posterior, pelvic tumors, multiparity, placenta previa, cephalopelvic disproportion
- MC LIE = TRANSVERSE LIE (20%)
- US at onset of labor to determine lie and cord position. Cont fetal monitoring
- tx: pelvic exam, place patient in knee-chest pos., and apply continuous upward pressure against presenting part to lift and maintain fetus away from prolapsed cord
PROM etiology, RF, sxs
- RF: genital tract infxn (BV), smoking, prior PPROM, shortened cervical length, amnio
- rupture of membranes before onset of labor
- important cause of PTL, prolapsed cord, placental abruption, and intrauterine infxn
- NIH recommends use of steroids in PROM pts before 32wks in absence of amniotic infxn
- sxs: term >37wk, sudden gush of fluid or continued leakage
- avoid digital exam
PROM dx and tx
- dx: hallmark findings are ferning, nitrazine testing (amnio fluid - paper turns blue = alkaline), pooling, CBC and UA, phosphatidyl glycerol (indicates pulm maturity), AFI w/ US
- tx: if chorioamnionitis present, active delivery indicated regardless of gest age
- if no infxn and term, manage expectantly or actively
- if no infxn and preterm, similar delivery to PTL
- abx and hydration prolongs latency period by 5-7d - IV ampicillin and IV erythromycin
- tocolysis: prolongs interval to delivery to gain time for steroids to be administered (only 48h - longer increases risk of infxn)
PPROM
- occurs before 37wks
- major risk involved is chorioamnionitis and endometritis
- chorio: cause = myco/ureoplasma, sxs = uterine tenderness, tachycardia (maternal and fetal), foul smelling purulent amniotic fluid, maternal leukocytosis, tx = ampicillin + gentamycin
- tx: if no sign of maternal or fetal iunfxn or distress, expectant management preferred - pt admitted to hospital and put on bedrest
- if under 34wks, steroids administered
- NST and BPP performed daily to assess fetal well-being
- amnio checks lung maturity
Preterm labor/delivery
- delivery of viable infant before 37 wks gest.
- MCC neonatal deaths not from congenital malformations
- LBW infants born prematurely often have significant developmental delays, cerebral palsy, and lung dz
- RF: smoking, cocain use, uterine malformations, cervical incompetence, infxn, and low prepreg weight
- preterm labor defined as regular uterine contractions (>4-6/hr) between 20-36wks gest. and in the presence of one or more of the following:
- cervical dilation of 2cm or greater at presentation
- cervical dilation of 1cm or greater on serial exam
- cervical effacement of greater than 80%
- dx: US - normal length of cervix = 4cm
- tx: bed rest, abx, hydration, steroids, tocolytics (mag sulfate, CCB)
barrier methods of contraception
