Summary
Endoscopic delivery of surfactant to preterm fetuses during labor is feasible. This innovative technique shows promise for fetal lung development before birth, with no immediate complications observed.
Area of Science:
- Perinatology
- Fetal Medicine
- Endoscopic Surgery
Background:
- Preterm birth complications necessitate interventions to improve fetal lung maturity.
- Current surfactant administration methods are typically postnatal.
- Assessing the feasibility of antenatal or intrapartum surfactant delivery is crucial.
Observation:
- A gas-sterilized intraoperative fiberscope was endoscopically guided into the amniotic cavity of three preterm labor patients.
- Surfactant was directly administered into the mouths of fetuses via a catheter through the fiberscope.
- Fetal heart rate, maternal, and neonatal outcomes were continuously monitored.
Findings:
- In utero endoscopic surfactant delivery was successfully achieved in all three cases.
- Fetal heart rate remained stable, indicating procedural tolerance.
- No maternal or neonatal infections or complications were detected post-procedure.
Implications:
- This preliminary study demonstrates the feasibility of endoscopic intrapartum surfactant administration to human fetuses.
- Intrapartum endoscopy offers a potential route for prophylactic fetal surfactant therapy before the first breath.
- Further prospective controlled studies are warranted to establish the clinical utility and efficacy of this technique.
