REBEL Core Cast 46.0 – Resuscitative Hysterotomy

Take Home Points

• This is a resuscitative hysterotomy – focus is on saving the mother first. Delivering the fetus can improve venous return thus increasing chance to save mom
• Don’t focus on gestational age to make the decision – if you think the belly is big enough to be causing compression of vascular structures, the procedure is indicated
• Once you’ve made the decision – it’s go time. The faster you do it, the more likely you can salvage mom and the fetus
• Large vertical incision to maximize exposure, locate uterus, vertical incision with scalpel and extend with scissors

REBEL Core Cast 46.0 – Resuscitative Hysterotomy

Resuscitative Hysterotomy

Critical Concept: The goal of the procedure is to resuscitate the mother. Performing a resuscitative hysterotomy improves the chances of saving the mother. The procedure can also improve outcomes for the fetus.

Key to procedure: The procedure itself is not difficult but the decision to make the incision is difficult. Delays in procedure lead to worse outcomes in both mother and fetus

Prior to arrival

• Run through the Zero Point Survey
  • Setup and prepare
  • Rally your consultants – OB/GYN, Trauma, Anaesthesia
• Team assignments: Need multiple teams
  • Resus team
  • Airway team
  • Hysterectomy team
  • Fetus team
  • If trauma -> blood & thoracotomy team

Indications

• Cardiac arrest
• Periarrest
• Uterus large enough to cause compression on vasculature
  • Fetus >20 weeks often quoted but, can be challenging to calculate the gestational age in a high-stress situation
  • Uterus palpable above the umbilicus can be used as well

Pre-Procedure

• Time is of the essence
  • Skip sterility, measuring fetal HR or waiting for OB
• If medical arrest -> continue CPR and arrest algorithm
• If traumatic arrest -> another team should be performing a thoracotomy if indicated

The Procedure

• Equipment: scalpel, scissors (ideally blunt tipped), and two Kelly clamps
• Located xiphoid process and pubic symphysis
• Use scalpel to cut from xiphoid process to pubic symphysis. Need to cut down through multiple layers until you reach the uterus
  • Have assistant retract both edges of your incision
• Make a small, 3-4 cm incision with a scalpel into uterine fundus (low incision recommended)
• Will see a rush of amniotic fluid
• Use your scissors to extend the incision caudally
• Can place fingers into the uterus to guide scissors and avoid the fetus
• Deliver baby headfirst – grasp behind neck supporting the head
• Clamp umbilical cord and cut – pass the baby to neonatal resus team
• Deliver placenta
• Pack the uterus
