Abstract

Objectives: The purpose of this study is to compare the vacuum extractor cup application technique described by Bird vs. the technique described by Vacca on a simulation model.Methods: Six obstetricians participated in the study. Each obstetrician performed eight vacuum assisted deliveries using the Bird technique and eight vacuum assisted deliveries using the Vacca 5-Steps technique.Results: A total of 96 vacuum assisted deliveries were performed. The mean distance from the centre of the cup to the flexion point was 1.78 +/- 0.96 cm for the Bird technique and 1.05 +/- 0.60 cm for the Vacca technique (p<0.001). The lateral distance (over the parietal bone) was 1.16 +/- 0.69 cm for the Bird technique and 0.66 +/- 0.52 cm for the Vacca technique (p<0.001). The vertical distance (towards the frontal or occipital bone) was 1.12 +/- 1.02 cm for the Bird technique and 0.67 +/- 0.55 cm for the Vacca technique (p=0.009). In occipito anterior positions, there were no significant differences between both techniques.Conclusions: The Vacca technique was better in transverse and posterior positions.

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 11 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 1.
  • The number of mentions on the social network X (formerly Twitter): 2 (Altmetric).
