EMS Protocol of the Week - Emergency Childbirth

Hi all, 


This week we will be focusing on Emergency Childbirth


The prehospital approach exists as a progression of care based on the provider’s level of training. CFRs start with ABCs and monitoring vital signs for shock. They will check for crowning and if present prepare for imminent delivery. 


This is a general outline to help providers: 


1) Apply gentle pressure against the delivering newborn’s head to prevent tearing of the perineum 

2) Gently clear the airway of secretions using a bulb syringe

3) Support the head and chest as the newborn delivers

4) Repeat suctioning as necessary prior to spontaneous or stimulated respirations

5) Gently guide the head downward until the shoulders appear. Deliver the other shoulder with gentle upward traction

6) Thoroughly but rapidly dry the newborn with a clean, dry towel 


After delivery, delay clamping of the umbilical cord for up to 1 minute after uncomplicated delivery. Wrap the newborn in a dry, warm blanket/towel. Assess the mother for postpartum hemorrhage and shock. When safe to do, place newborn on mother’s chest. 


If the on-scene team is BLS-trained, they will be able to assess and help manage breech presentations, prolapsed cord, nuchal cords, intact (not ruptured) amniotic sacs, shoulder dystocia, and multiple births. See the attached protocol for detailed recommendations for these special considerations. 


KEY POINTS: 

  • Consider supine hypotension syndrome as a cause of shock 

  • Newborns are subject to rapid heat loss and must be kept warm and dry 

  • Miscarriage usually occurs at less than 20 weeks of gestation. Begin resuscitative efforts of the newborn if the gestational period is unknown 

  • The turtle sign is when the newborn’s head retracts back into the vagina, and is an indication of shoulder dystocia 

  • It is no longer suggested to perform aggressive suctioning of the newborn when meconium is present  

  • Do not aggressively suction premature newborns

EMS Protocol of the Week - Neonatal Care / Resuscitation

The prehospital protocol for neonatal resuscitation is dense, so it doesn't serve to reproduce it all within the email. Read through the attachment for details, and realize that it serves as a reference for stepwise assessment (with target heart and respiratory rates) and interventions (with target compression/ventilation rates and medication dosages) for when our EMTs and paramedics are stuck in a high stress home environment with a neonate in extremis. Not a ton to add from an OLMC perspective, but recognize that this protocol is here for your reference as well, in case a crew calls looking for assistance.

The attached appendix also includes a review of APGAR scores for your review. 

That's RESUSCITATION...BABY.

And with that, hope you all have some wonderful holidays! If you can't wait for more protocol goodness, there's always www.nycremsco.org

POTD: Umbilical Vein Catheterization

I wanted to review a fairly rare but lifesaving EM procedure in neonates. This procedure is done fairly commonly in the NICU/L&D, but is done less frequently in the ED, especially with our excellent nurses who can literally get the most impossible venous accesses. If you went to Airway day, you might recall Dr. Sokolovsky describing her harrowing tale of providing neonatal resuscitation at Burning Man and performing an umbilical vein catheterization with an 18-gauge IV. Super wild! So for anyone who might find themselves in a similar poop-inducing situation with no pediatric support or NICU available, this is for you!


Umbilical vein catheterization is indicated in a neonate within 14 days post-birth requiring IV resuscitation. The stump must be "fresh", so it is most ideal in the newly born neonate. Here is an excellent video overviewing the following steps. https://pedemmorsels.com/wp-content/uploads/2019/08/UVC....mp4

Here's what you'll need:

  • Sterile gloves (gown and drape less non urgent)

  • chlorhexidine

  • forceps

  • scalpel

  • umbilical line (5 French is standard, 3.5 French in very premature baby)

  • three-way stopcock

  • umbilical tape of 3-0 silk/nylon

  • NS flush

In peds, we have umbilical vein catheterization trays located on the top shelf in Bay 31 that includes all of the above except the catheter. While the umbilical line is the traditional teaching, you can use any tube that can fit into the vein - that means an 18 gauge IV, pediatric central line, feeding tube, etc


Prep the umbilical stump

  1. Flush the line and place

  2. Sterilize the entire umbilical stump, including the clamp at the end of the stump, and the abdomen

  3. Tie the umbilical tape (or a silk string) around the base of the stump loosely. This helps decreased blood flow for when the clamp is eventually removed. It can also be tightened to secure the line once placed

  4. Holding the clamp, make a transverse cut off the stump to remove the distal tip. Cut should be made directly below the clamp or 2 cm from the abdomen.

Identifying umbilical vein and prep for insertion

  1. Identify the umbilical vein. The anatomy of the stump involves two smaller umbilical arteries and one umbilical vein. The arteries are typically smaller and thicker lumen, while the vein is larger and more collapsible (see below)

  2. Remove any clots from the vein and gently dilate the vein with forceps

  3. gently insert the line, when you get blood return insert 1-2 cm deeper, or approx 3-5 cm. If there is resistance, consider loosing the umbilical string.

  4. Aspirate blood and flush with NS. Secure the line by tightening the umbilical string and securing with tape or purse string suture

Complications of UVC placement are similar to CVP placement: excessive bleeding, infection, thrombosis, arterial insertion. Specifically to UVC is risk of insertion too deep into the portal venous system or right atrium, which can lead to hepatic necrosis and perforation.
