Another case series of 3 resuscitative hysterotomies, all performed by obstetricians, reported 33% maternal and 67% neonate survival.(1). 
The mechanics of the procedure are:

• “Duration should not exceed 5 minutes!
• Incise from pubic symphysis to at least umbilicus with a large scalpel along linea nigra into peritoneal cavity. Layers: skin, subcutaneous tissue, fascia between the rectus muscles, peritoneum.
• Retract abdominal wall laterally
• Reflect bladder inferiorly and empty by aspiration
• Make a small incision (~5cm) vertically into the inferior presenting part of the uterus until amniotic fluid comes or through endometrium
• Insert 2 fingers and lift up uterus from foetus
• Extend uterine incision up to fundus with safety scissors curved away from foetus
• Deliver the foetus. May need to disengage the presenting part from the pelvis.
• Clamp the cord twice and cut between clamps
• Give the neonate to the neonatal resuscitation team” (2)
