OBJECTIVE: The objective of this study was to assess the use and efficacy of delivery by vacuum extraction or ventouse in routine clinical practice and to assess some aspects of the procedure that may reflect the quality of training in this technique. MATERIALS AND METHODS: Women's demographic profiles and delivery details were collected in both the prospective (B) and retrospective (A) arm of the study. In addition, in the prospective arm of the study two custom-designed forms were used: the obstetrician recorded their perception of where the vacuum cup had been placed on one form while on a second form the pediatrician indicated the actual site of the cup placement as observed from the position of the chignon. All the diagrams of cup placement were reviewed by one of the authors, who was blinded to the outcome of the procedure. RESULTS: The vacuum extractor was the first instrument to be used in 79% and 87% of the instrumental deliveries in groups A and B, respectively, with corresponding failure rates of 20% and 21%. Although an occipito-posterior position was diagnosed in 11% of cases of group A and 14% of cases of group B, the specifically designed occipito-posterior cup was not used at all. The vacuum cup was considered to have been applied suboptimally in 40% of the cases where attempted vacuum delivery failed. CONCLUSION: The high rate of inappropriate positioning of the cup may reflect difficulty in accurately applying the cup, perhaps due to caput or malposition, but may also represent poor assessment of the orientation and position of the fetal skull and therefore be indicative of a need for improvement in training methods.
