Plan for cervical incompetence risk
- Discuss the options of transvaginal cerclage (TVC) or transabdominal
cerclage (TAC)
- Surveillance for cervical change
- Dynamic testing (fundal pressure)
- Aggressive suppression of uterine activity to reduce pressure
on cervix
Plan for chorion sharing
- First trimester evaluation of fetal number and chorions/amnions
- Frequent ultrasounds between 16 and 28 weeks
- Monitor relative amniotic fluid volumes
- Monitor size discordancy
- Focused evaluation if oligo/poly or discordance
- Amnioreduction if oligo/poly (Chorionic vessel interruption)
Surveillance for/treatment of preterm labor
- Surveillance for evolution of uterine activity
- Serial cervical evaluation by TV ultrasound
- Modulate intervention according to effects on cervix
- Bedrest
- Calcium channel blocker
- Subcutaneous terbutaline infusion
- Intravenous magnesium sulfate
- Indomethacin
Surveillance for growth deficiency
- Serial ultrasound assessment of growth
- Interfetal less important than intrafetal comparison
- IGR will happen if carry long enough
- IGR probably important by itself, but probably not curable
by delivery
- Biophysical surveillance for risk of fetal death
- Delivery of one means delivery of all
Surveillance for/amelioration of preeclampsia
- Minidose aspirin
- Early detection of hypertension
- Bedrest/antihypertensives
- Assessment of proteinuria/LFT/Platelets
- Fetal biophysical surveillance
- Deliver for fetal status or ominous signs
- Management of fluid shifts postpartum
Monitoring for risk of demise
- NST’s must provide simultaneous recording
- Biophysical profile probably most applicable
- UA flow dynamics probably adjunctive, rather than centrally
diagnostic
- Subjective fetal movement assessment
Planning for delivery
- Statistically, 35 weeks is point of lowest risk
- Individualization is critical
- Amniocentesis in face of IGR and 34 weeks
- Biophysical deterioration at > 27 weeks
- Difficult decision before 28 weeks
Management of delivery
- Blood available, depending on uterine size and clinical situation
- Cesarean if 3rd trimester
- Potent uterotonics available
- Plan for hypogastric or uterine artery ligation if large uterus/late
gestation
- B-Lynch is a consideration
- Possibility of hysterectomy
