A 34-week preterm fetus requires an operative vaginal delivery for fetal distress. Which of the following is an absolute contraindication to vacuum extraction in this scenario?
- A Occiput anterior position
- B Gestational age less than 37 weeks
- C Station at +2
- D Gestational age less than 34 weeks ✓
Correct answer: D. Gestational age less than 34 weeks
Explanation
Vacuum extraction is contraindicated at gestational ages below 34 weeks due to the high risk of subependymal and intraventricular hemorrhage. Station +2 and occiput anterior are favorable conditions for vacuum delivery. While 37 weeks defines preterm, the specific absolute cutoff for vacuum safety is 34 weeks.
