POTD: Neonatal Resuscitation

We’ll be going over a few high yield topics pertaining to NALS today. 

It’s 7:30 AM, and you’ve just unwrapped your BEC sandwich and taken your first sip of coffee. You’re settling into the morning getting ready for your 12 hour peds shift… until the phone rings, and you get a note: 

“Mother 38w delivered her baby at home 30 minutes ago. Baby is having labored breathing, and is bradycardic. EMS will be here in 2 minutes.”

Take a deep breath. First, remember the basics. If you’re in a facility that has Peds/NICU, call them immediately. Call respiratory. Call pharmacy. Call Hector. Use the resources available to you. 

The set up.

Get the warmer and set it to 25 C

  • Avoid hypothermia in these patients. The goal is > 36.5-37.5C

Grab the Broselow tape so that it’s available for immediate use.
Get the backboard.
Grab the code cart, zoll
Get a towel to warm and dry the baby.
Get your airway equipment ready:

  • Suction x 2, plugged in, ready to go

  • Oxygen: grab the neonatal BVM and plug it into the oxygen port

  • Airway equipment: have both DL/VL equipment,

    • LMA size 1

    • Pre-loaded tubes

      • 2.5 and 3.0 uncuffed tubes

    • Blades: 0 and 1

    • EtCO2

Access: IO gun + pink needles ready for use; umbilical vein catheters (future POTD)

Grab your PALS card or open up your PediStat app
Ultrasound

Assess the patient.

Pediatric assessment triangle:

  • Appearance – crying? Good tone? Tracking?

  • Breathing – nasal flaring? Stridor? Grunting? Head bobbing?

  • Circulation – Pallor? Cyanosis? Mottling?

Off the bat, there are two numbers you need to remember:
HR < 100→ initiate positive pressure ventilation (PPV)
HR < 60→ initiate CPR / epinephrine if this is sustained more than 30 seconds despite adequate ventilation.

  • NOTE: Bradycardia is almost always related to hypoxia, so atropine isn’t routinely indicated for these patients.

Remember, the most important part of neonatal resuscitation is positive pressure ventilation.


PPV.

If the patient is spontaneously breathing but labored, you can place them on CPAP.
Remember, the targeted SpO2 after birth is much lower for neonates, so see the box below. You’re more interested in ventilating than the oxygenation.
For gasping / apneic / HR < 100 patients, initiate PPV. You can use 5 on the PEEP valve.

  • Rate: 40-60 breaths / minute

MR SOPA mnemonic for ventilation tips:

  • Mask, right size

  • Reposition airway

  • Suctioning nares

  • Open mouth

  • Pressure increase to PEEP to ~5

  • Advanced airway: ETT / LMA

BGM.

They also have lower BGMs. Hypoglycemia for neonates is < 30 for a patient < 24 hours old. It’s recommended to give D10 bolus 2ml/kg if the patient is hypoglycemic.

You can give glucagon IM too: 0.03mg/kg max 1mg

CPR.

It’s recommended to secure an airway (supraglottic or ETT) prior to doing compressions) since most these codes are usually due to respiratory events.
The ideal ratio is3 compressions:1 breath

  • Goal is 90 compressions: 30 breaths in one minute

2 thumb compression technique (*preferred) or 2 finger technique
Pulse checks q1 min
Depth: ⅓ chest diameter

Epinephrine.

IV dosing: 0.01mg/kg q3-5min
ETT dosing: You can give epinephrine through the ETT too if you don’t have access yet! AHA recommends a larger dose 0.1mg/kg of 1:1000 ETT

  • Max dose is 10mg, and follow it with a saline flush

I highly recommend reviewing the following flowchart linked.

I hope this was a good refresher on some of the most important concepts. I would love to learn other tips that others have in managing these stressful situations!

Pediatric Fever

Infant < 28 days: Do everything & give empiric Abx (Ceftazidime, Acyclovir (HSV) & Ampicillin) ^

CBC, BMP, Blood Cx (1 set), UA, Urine Cx, LP, RVP*

^There are new guidelines regarding patients who are between 3-4 weeks of age where LP may be deferred. There is a lot of controversy still regarding its adoption.

28 days to 2 months / 1st set of vaccines: Do everything however LP & Abx dependent on PECARN Rule for Low Risk Fever

CBC, BMP, Blood Cx (1 set), UA, Urine Cx, RVP*, Pro-Calcitonin

PECARN Rule for Low Risk Fever: LP if any of the following is positive: Pro-Cal > 0.5, ANC > 4090/micoL, Positive UA (due to seeding of CNS). PECARN Rule for Low Risk Fever was done in full term infants without chronic medical problems, no prolonged NICU stay - use discretion in patients with multiple risk factors.

If performing LP, the patient will need abx (Ceftriaxone 100mg/kg) coverage pending CSF studies.

2 months - 4 months / 2nd set of vaccines: Partial Sepsis. No LP unless clinical signs of meningitis due to blood brain barrier

CBC, BMP, Blood Cx (1 set), UA, Urine Cx, RVP*.

Can consider one dose of IV ceftriaxone (75mg/kg) if WBC > 15k, WBC < 5k, or Band to Neutrophil Ratio greater than 0.2. The evidence is not very robust and practice varies.

4 months - 6 months / 3rd set of vaccines: Urine

UA, Urine Cx, RVP*

6 months - 12 months: Urine collection requirement varies

  • Females: UA, Ucx, RVP*

  • Circumcised males- No urine, RVP*

  • Uncircumcised males- Urine if fever > 48 hrs , RVP*

1- 2 years of age: Urine collection in females

  • Female: UA, UCx, RVP*

  • Males: No urine, RVP*

*RVP can be useful for finding a source of fever (calming parent anxiety, limiting atypical Kawasaki workup etc...). However, remember patients can have more than one concomitant source of illness and a positive RVP should not prevent one from finishing the appropriate workup in each age group.

POTD: Hair Tourniquet

This POTD is inspired by a case I saw from the periphery while in the Peds ED. I'll be discussing hair tourniquets!

Toe-tourniquet syndrome, also called Hair-thread tourniquet syndrome (HTTS), is a rare and commonly misdiagnosed condition caused by hair or fiber wrapped around digits (fingers and toes), penis, or even clitoris. It usually affects infant and children. Prompt diagnosis is needed as ischemia can result.

This is a diagnosis often missed because the presentation is so vague. Often the only complaint is a crying and inconsolable infant. This is why the physical exam is so important! Redness and swelling distal to a constricting band is usually found, so check all of those digits and do a thorough genital exam.

Treatment includes early recognition of the condition and immediate release of constriction to prevent devastating complication in the form of digit loss or genital damage. Careful circumferential examination of affected part should be done as swelling and erythema, can mimic infection, so correlate clinically with the history. A hand held magnifying glass can be useful in circumstances where the diagnosis is not certain.

Simple removal with scissors or even an IV catheter needle could do the trick. If the skin is intact, hair removal agents, such as Nair, can be used. Apply the agent on the area for about 8 minutes and then rub the agent and hair off. If all else has failed, consider a dorsal slit for cases where skin is broken and tourniquet is too tight for other methods.

With successful removal of the hair tourniquet, patients are discharged home with appropriate follow up.
