In the Prospective Optimum Fetal Monitoring (INFANT) trial, the use of computer decision support (INFANT system) during intrapartum fetal monitoring with CTG was associated with:
- A Significant reduction in perinatal mortality and morbidity
- B Reduction in caesarean section rates by 15%
- C No significant difference in adverse perinatal outcome compared to CTG alone ✓
- D Improved detection of metabolic acidosis at birth
Correct answer: C. No significant difference in adverse perinatal outcome compared to CTG alone
Explanation
The INFANT trial (Lancet 2017) was a large RCT evaluating computer decision support (the INFANT system) alongside CTG in over 46,000 women. Despite theoretical advantages, it found no significant difference in adverse perinatal outcomes (composite: stillbirth, neonatal death, early seizures, metabolic acidosis, etc.) compared to standard CTG interpretation. This highlighted the limitations of automated CTG analysis and the ongoing challenges in intrapartum fetal surveillance.
