Rising Trends in the Incidence of Shoulder Dystocia and Development of a Novel Shoulder Dystocia Risk Score Tool: A Nationwide Population-Based Study of 800,484 Finnish Deliveries

摘要

Shoulder dystocia is an unpredictable, obstetric emergency. Its incidence has been reported to range from 0.1 up to 3.0. Some risk factors that have been associated with shoulder dystocia are maternal obesity, maternal diabetes, and operative vaginal delivery (OVD). However, the individual predictive value of these risk factors has been poor. In Finland, the incidence of shoulder dystocia is unknown, and no tools exist to estimate the risk of this complication. The aims of this study were to determine the incidence of shoulder dystocia, identify risk factors, and develop a clinical tool to evaluate the risk.
