What birth weight predicts shoulder dystocia?

EFW >4,000 g doubles shoulder dystocia risk to ~5-7%. EFW >4,500 g in diabetic pregnancies: risk 20-25%. Shoulder dystocia occurs in 40-65% of cases without EFW >4,000 g. Accurate prediction is limited; management preparation is the key goal.

What is the HELPERR mnemonic for shoulder dystocia?

H=Call for Help; E=Evaluate for Episiotomy; L=Legs (McRoberts); P=Suprapubic Pressure; E=Enter (Rubin II/Woods screw); R=Remove the posterior arm; R=Roll the patient (Gaskin all-fours). Each step takes 30-60 seconds.

What is the neonatal outcome of shoulder dystocia?

Brachial plexus injury in 5-20% of shoulder dystocia cases; most resolve within 1 year. Permanent Erb palsy in 0.3-0.4%. Hypoxic injury risk increases significantly with head-to-body delivery interval >5 minutes.

Shoulder Dystocia Risk Score and Maneuver Algorithm

Calculate macrosomia-based shoulder dystocia risk and apply systematic maneuver sequence: McRoberts + suprapubic pressure, Rubin II, Woods screw, posterior arm delivery, Zavanelli. Higher EFW and maternal diabetes increase risk.
