Third-Trimester Counseling Strategy
30 Weeks Gestation · Patient-Centered Care Framework
"Incompatible with life" — medically inaccurate; impairs shared decision-making.
"Life-limiting" diagnosis with highly variable outcomes and a subset of long-term survivors.
Patient-Centered Care mitigates value conflicts and reduces psychological harm.
Provide accurate statistics. Avoid therapeutic nihilism.
Substantial stillbirth risk persists throughout the third trimester.
Significant growth retardation in the vast majority of T18 fetuses.
Preterm birth ratio approximately 35% in T18 pregnancies.
Polyhydramnios and preeclampsia may necessitate early delivery.
Chosen when parents elect operative intervention for non-reassuring fetal heart rate (NRFHR).
Appropriate when parents prioritize maternal safety and decline cesarean delivery for NRFHR.
Document explicit directives in the maternal chart.
T18 pregnancies carry an extremely high rate of cesarean delivery, most frequently driven by NRFHR.
Establish parental threshold for surgical intervention before labor begins.
Vaginal delivery may be prioritized to protect maternal health even in the setting of NRFHR.
Explicit written directives for intrapartum resuscitation and operative delivery restrictions.
Warmth, feeding, skin-to-skin contact, symptom management. No intubation or cardiac surgery.
NICU trial to assess baseline viability and anatomic severity before committing to long-term support.
Mechanical ventilation, cardiovascular support, surgical evaluation for correctable defects.
AAP supports offering options based on informed parental values. (AAP Clinical Report)
Ongoing sonographic surveillance, obstetric planning, and intrapartum directives.
Realistic NICU capabilities discussion; resuscitation limits and time-limited trial planning.
Confirm karyotype; discuss recurrence risk and chromosomal mosaicism if applicable.
Comfort protocols, bereavement support, and family-centered care planning prior to delivery.
Psychosocial support, community resources, and spiritual care for the family unit throughout the perinatal period.
| Domain | 🌿 Palliative / Comfort Care | 💋 Intensive / Life-Prolonging |
|---|---|---|
| Fetal Monitoring | Intermittent auscultation or discontinued | Continuous electronic fetal monitoring |
| Delivery Mode | Vaginal delivery prioritized; no CD for NRFHR | CD offered for NRFHR or malpresentation |
| Neonatal Resuscitation | Oropharyngeal suction, warming, supplemental O₂ | Full NRP, positive-pressure ventilation, intubation |
| Postnatal Location | Mother's room or private palliative suite | Neonatal Intensive Care Unit (NICU) |
| Cardiac Management | No surgical intervention for congenital defects | Echocardiography; surgical evaluation if indicated |
Use "life-limiting" framing. Provide accurate survival data without nihilism.
Explicit chart orders for monitoring, delivery mode, and resuscitation preferences.
MFM, Neonatology, Genetics, and Palliative Care engaged before delivery.
Construct a clear postnatal plan aligned with family goals and values.
Trisomy 18 counseling at 30 weeks is not about predicting outcomes —
it is about preparing families for every possibility.
