Implication
Case-control study finds vacuum extraction and high birthweight increase shoulder dystocia-related brachial plexus injury risk.
Key Points
- The study aimed to identify risk factors for brachial plexus injuries related to shoulder dystocia in Finland.
- Case-control study analyzing deliveries in Helsinki and Uusimaa from 2006 to 2015.
- Identified singleton deliveries with shoulder dystocia, brachial plexus injury, and clavicle fracture using ICD-10 codes.
- Conducted multivariate analysis to determine independent risk factors.
- Developed a predictive model based on identified risk factors.
- Overall incidence of brachial plexus injury declined significantly during the study period.
- Identified risk factors include birthweight ≥4000 g, maternal diabetes, vacuum extraction, and maternal height ≤160 cm.
- A predictive model demonstrated a positive predictive value of 48.2% and a negative predictive value of 92.9% for shoulder dystocia-related brachial plexus injuries.
