Question

The flexion point in a ventouse delivery is located at which of the following positions on the fetal head?

• A. 3 cm posterior to the anterior fontanelle
• B. 3 cm anterior to the posterior fontanelle
• C. 6 cm anterior to the posterior fontanelle
• D. Midway between the anterior and posterior fontanelle

Hint:

During a ventouse delivery, the flexion point should be approximately 3 cm anterior to the posterior fontanelle to ensure safe and effective use of the vacuum.

Answer 1

The Correct Option is B

In a ventouse (vacuum-assisted) delivery, the flexion point on the fetal head is typically located about 3 cm anterior to the posterior fontanelle. This position is crucial for the optimal application of the ventouse, as it allows the provider to apply traction in the most effective way to assist in delivery. The correct placement of the ventouse on the fetal head ensures the best chances of success while minimizing the risk of fetal injury.
