Objective:
To compare a one-step (rapid) application of negative pressure (vacuum) with conventional stepwise application for ventouse extraction following a prolonged second stage of labour.
Design:
Randomised controlled study.
Setting:
Teaching Hospital.
Participants:
Forty-seven women were randomised to the rapid vacuum group and 47 to the stepwise group.
Main Outcome Measures:
Duration of ventouse procedure, effectiveness of methods of application, morbidity of mother and infant.
Results:
There was no significant difference in frequency of detachment of the cup after rapid or stepwise application of vacuum. A reduction in mean duration of the ventouse procedure of 6 min was realised without significant difference in maternal or neonatal morbidity.
Conclusion:
Rapid application of vacuum significantly reduces the duration of a ventouse extraction procedure without compromise to efficiency and safety.
