RESULTS
Of the 23 336 women who delivered in the maternity unit from 2010 to 2018, 1097 benefited from an attempt at mid-cavity VAD and met the inclusion criteria (Figure 1).
Eight sequential uses of instruments were performed (failed VAD followed by successful spatula-assisted delivery). These women were included in the group “successful VAD”.
The values of 12 potential risk factors were significantly different between the successful VAD group and the failed VAD group. Except for the five-minute Apgar score, all maternal and neonatal outcomes were significantly better in the successful VAD group (Table 1).
