Morbidity

Delivery

Shoulder dystocia

  • Head-to-body delivery > 60 sec
  • Risk factor
    • Fetal macrosomia (fetal weight >4.5kg)
      • Post-term pregnancy (?42 weeks gestation)
      • Maternal obesity, GDM, excessive maternal weigh gain during pregnancy.

Maternal and neonatal consequences

  • Brachial plexus injury, acidosis/hypoxia?

Prediction and prevention

  • Warning signs of an impending dystocia
    • Prolonged first or second stage of labor
    • Retraction of the fetal head into the perineum after delivery (eg, turtle sign)

Management

  • B: breathe; do not push
  • E: elevate legs & flex hips, thighs against abdomen (McRobets)
    • To increase the diameter of the bony pelvis
  • C: call for help
  • A: apply suprapubic pressure
  • L: enlarge vaginal opening with episiotomy
  • Maneuvers
    • Deliver posterior arm
    • Rotate posterior shoulder (Woods screw) – apply pressure to anterior aspect of the posterior shoulder
    • Adduct posterior fetal shoulder (Rubin) – apply pressure to the posterior aspect of the posterior shoulder
    • Mother on hands & knees – “all fours” (Gaskin)
    • ??? C/S (>5kg, DM?? >4.5kg) 
      • Replace fetal head into pelvis for cesarean delivery (Zavanelli)
    • ? ? Rubin/intentional clavicle fracture
