Summary
Maternal diabetes and hypertension were common in mothers with shoulder dystocia related fetal injuries. Diabetes, a likely cause, predisposes to complications like preeclampsia and shoulder dystocia.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Medical Malpractice
Background:
- Shoulder dystocia is a significant obstetric emergency associated with fetal injury.
- Identifying antenatal risk factors for shoulder dystocia is crucial for improving perinatal outcomes.
- Malpractice claims provide a unique dataset for analyzing obstetric complications and their antecedents.
Observation:
- Review of 240 malpractice claims for shoulder dystocia-related fetal injuries revealed frequent antenatal complications.
- Chronic or pregnancy-induced hypertension occurred in 33% of cases.
- Pregnancy-induced or pre-existing diabetes was diagnosed in 20% of cases, often poorly controlled.
Findings:
- The incidence of hypertension and diabetes in this cohort was significantly higher than the general population (5%).
- Hypertension, while linked to fetal growth restriction, is unlikely to directly cause shoulder impaction.
- Maternal diabetes is identified as the probable common denominator, predisposing to both preeclampsia and shoulder dystocia.
Implications:
- Demonstrating the link between maternal conditions like diabetes and adverse fetal outcomes can influence malpractice litigation.
- Improved antenatal screening for diabetes is warranted, as current screening may underestimate its incidence.
- Understanding these associations can inform clinical practice and patient counseling to mitigate risks associated with shoulder dystocia.
