What is the role of ultrasound in predicting shoulder dystocia?

The role of ultrasound in predicting shoulder dystocia primarily involves its ability to assess fetal size and positioning. This assessment can provide crucial information regarding the likelihood of encountering complications during delivery. For instance, larger fetal size, especially in cases of macrosomia, is a known risk factor for shoulder dystocia. Additionally, the positioning of the fetus in the womb can influence delivery dynamics and the potential for complications. By utilizing ultrasound, healthcare providers can gather essential data that helps in planning and managing labor effectively, thereby addressing potential risks associated with shoulder dystocia.

The other options do not accurately capture the role of ultrasound in this context. While confirming the delivery date and ensuring there are no complications during labor are important aspects of prenatal care, they do not directly relate to the prediction of shoulder dystocia. Likewise, stating that ultrasound has no relevance undermines its critical role in evaluating factors that may contribute to this obstetric emergency.
