Cesarean section for failed vacuum extraction : risk factors and maternal and neonatal outcomes
OBJECTIVE: To evaluate risk factors associated with failed attempts of vacuum extraction and their outcomes.
PATIENTS AND METHODS: All trial vacuum extractions (metal Minicup) from 1992 to 2000 in Besançon University Hospital Center were retrospectively analysed, namely 2447 cases. Univariate and multivariate analyses of failed vacuum extraction risk factors and descriptive analyse of outcomes were performed.
RESULTS: The rate of failed vacuum extractions was 3.47% (85/2447). A multivariate analysis showed the following independent risks factors in failed extraction: extraction above pelvic level + 2 (OR = 1.8; CI 95%: 1.1-3), newborn weight (OR = 2.9; CI 95%: 1.8-4.9), parity >2 (OR = 0.08; CI 95%: 0.01-0.6). In case of failed vacuum extraction, newborns had a significantly higher rate of Apgar score <7 at 1 min (P = 0.0002), but not at 5 min. These newborns were most regularly admitted in pediatric care units (P = 0.01).
CONCLUSION: The failed trial attempt vacuum extraction rate stays low. These failed instrumental extractions are more common in an extraction above pelvic + 2, a high fetal weight and an arrest during the second stage of labor. There is an increased adverse neonatal outcome. Clinical fetal weight estimation and diagnosis of presentation level in mother pelvis must be performed before vacuum extraction.
