Summary

Shoulder dystocia (SD) is often unrecognized during delivery, leading to a high rate of neonatal injuries. Most injured infants were born without the obstetrician identifying shoulder dystocia during birth.

Area of Science:

  • Obstetrics
  • Neonatal Medicine
  • Perinatal Research

Background:

  • Shoulder dystocia (SD) diagnosis relies on subjective criteria.
  • Timely recognition of SD is crucial for managing neonatal morbidity.

Purpose of the Study:

  • To test the hypothesis that infants with injuries consistent with SD are often born without intrapartum identification of the condition.
  • To evaluate the incidence and impact of unrecognized shoulder dystocia on neonatal outcomes.

Main Methods:

  • Retrospective analysis of 26,033 vaginal births.
  • Comparison of maternal and neonatal variables across three groups: SD diagnosed (uninjured/injured) and SD unrecognized (injured).

Main Results:

  • Identified 162 cases of diagnosed SD (0.62% incidence).

  • Of infants with injuries (brachial plexus, fractured clavicle), 71% were born without SD recognition.
  • Unrecognized SD deliveries showed increased neonatal injury risk compared to recognized SD.

    • Conclusions:

    • Shoulder dystocia is underreported, and unrecognized cases significantly increase neonatal injury risk.
    • Objective criteria and improved training models are needed to address this clinical challenge.
