Can shoulder dystocia be predicted before operative vaginal delivery using a score that includes ultrasonographic head-perineum distance measurement?

ABSTRACT:

Objective

The main study objective was to develop a novel shoulder dystocia (SD) prediction score using ultrasound-based head-perineum distance measured before an operative vaginal delivery (OVD).

Methods

This retrospective unicentric study (Lille, France) included all cases of OVD of singleton pregnancies from March 2019 to October 2020, with cephalic presentation and > 37 weeks of gestation, for which intrapartum sonography was performed. A multiclass-penalized logistic regression model was used to develop the SD prognostic score, with missing values imputed by multiple imputations.

Results

Among the 1708 patients with OVD, 773 who underwent ultrasound for head-perineum distance were included. SD occurred in 99 cases (12.8%). The SD's predicting factors (and their w
