Key clinical point: Management of shoulder dystocia with fetal manipulation (FM) increased the risk for obstetric anal sphincter injury (OASI), with FM being associated with an increased risk for OASI and severe neonatal morbidity.
Major finding: Shoulder dystocia managed with vs without FM resulted in significantly higher rates of OASI (21.1% vs 3.8%; odds ratio [OR] 6.72; 95% CI 2.7-15.8) but similar rates of severe neonatal morbidity. FM was associated with the occurrence of OASI (adjusted OR [aOR] 5.3; 95% CI 2.2-12.8) and was the only factor associated with severe neonatal morbidity (aOR 2.3; 95% CI 1.1-4.8).
Study details: Findings are from a retrospective observational study including 602 vaginal vertex deliveries in singleton pregnancies, which encountered shoulder dystocia that was managed with (n = 52) or without (n = 550) FM.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
