Case 11 · Obstetrics
Shoulder dystocia
The head is born and the shoulders will not follow. The clock on the monitor is the head-to-body interval, and it runs in real time. Call for help, work through McRoberts, suprapubic pressure and the internal manoeuvres without harmful traction, then resuscitate the newborn and protect the mother from haemorrhage.
About this case
What you will practise
Learning objectives
- Recognise shoulder dystocia and call for help, stating the problem clearly.
- Avoid fundal pressure and strong or downward traction, and ask the mother to stop pushing.
- Perform McRoberts and suprapubic pressure correctly, then move without delay to internal manoeuvres.
- Deliver the baby within about 5 minutes of the head.
- Resuscitate the newborn: airway, inflation breaths, ventilation, heart-rate checks, compressions only when indicated.
- Prevent PPH, examine for perineal tears, document and debrief.
Key decisions this case tests
- How do you recognise shoulder dystocia, and who do you call?
- Which side do you press from?
- When do you stop repeating first-line manoeuvres?
- Posterior arm or internal rotation?
- When does a newborn need compressions, and when not?

Before you start
The physiology is a simplified teaching model: the link between the head-to-body interval and the baby’s condition, and the newborn’s response to resuscitation, are timed for learning, not prediction. In this scenario the first-line manoeuvres are set to fail; in real life they resolve many cases. Doses follow the cited guidelines but have not yet been signed off by a clinician.
Visle is for education only and is not medical advice. Shoulder dystocia is an obstetric emergency: call for skilled help immediately.
