During a vacuum-assisted delivery, which of the following conditions is an ABSOLUTE contraindication to using a ventouse/vacuum?
- A Gestational age less than 34 weeks ✓
- B Occiput posterior position
- C Head not engaged (station above 0)
- D Previous uterine scar
Correct answer: A. Gestational age less than 34 weeks
Explanation
Vacuum extraction is contraindicated at gestational age < 34 weeks due to the fragility of the preterm fetal skull and soft tissues, with markedly increased risk of intracranial hemorrhage and subgaleal hematoma. Occiput posterior and non-engaged head are relative precautions but not absolute contraindications in all circumstances. A previous uterine scar is not a contraindication to vacuum delivery.
