During vacuum-assisted delivery, which of the following is considered an ABSOLUTE contraindication to the use of vacuum extractor?
- A Occiput posterior position
- B Gestational age < 34 weeks ✓
- C Second stage of labour > 2 hours in a nullipara
- D Maternal BMI > 35
Correct answer: B. Gestational age < 34 weeks
Explanation
Vacuum extraction is absolutely contraindicated at gestational age < 34 weeks due to the high risk of subgaleal haematoma, intracranial haemorrhage, and cephalhaematoma in preterm neonates whose skull bones are not yet adequately calcified. Occiput posterior position and prolonged second stage are indications for assisted delivery, not contraindications. RCOG guidelines list < 34 weeks as an absolute contraindication regardless of clinical circumstances.
