OBJECTIVES: After verification of the eligibility criteria and with an obstetrician familiar with the specific maneuvers likely to be needed, vaginal delivery of breech presentations is possible. If problems arise during the active pushing phase of labor, vacuum extraction has been described in the literature for this uncommon condition with limited series. The aim of this study is to assess retrospectively vacuum extraction in frank breech presentation in our center.
PATIENTS AND METHODS: This retrospective study of trials of vaginal delivery of fetuses in breech presentation at term compares cases according to whether they did or did not use a vacuum extraction.
RESULTS: During a two-year period, 83 patients, whom had trials of vaginal delivery in breech presentations, reached the active pushing/bearing down stage after complete cervical dilatation. Vacuum assistance was applied in six of these (7.2 %). The failure rate for vaginal delivery was significantly higher in the group with compared to without vacuum extraction (33.3 % versus 6.5 %, P<0.05). Moreover, the mean pH at birth was significantly lower in the group with vacuum extraction (7.12±0.11 versus 7.20±0.08, P<0.05), and these infants more frequently had deep cutaneous injuries (66.7 % versus 26.0 %, P<0.05).
DISCUSSION AND CONCLUSION: In fetuses in breech presentation, when vaginal delivery failed, it seems to be safer for the fetuses to perform caesarean section rather than attempt vacuum extraction.
