#SimBlog: A Tiny Surprise
Unexpected delivery of baby in adult A&E. Floppy and unresponsive… alarm buzzer pulled!
What would you do? How would you feel inside? How would you prepare? What would you do next? What happened next?
A: Patent, no meconium
B: Occasional gasps, poor chest rise
C: Pale colour, blue feet, heart rate slow
D: Poor tone, some responsiveness
E: Cold and wet
Okay, okay… for a newborn we don’t really do an A to E usually. We think colour, tone, breathing effort, heart rate – but under stress you might forget any NLS if you haven’t been trained. If you haven’t done NLS: rely on what you know. As we’ll see there are some important caveats.
In our simulation, the Consultant took charge accompanied by senior nurses. The neonatal stack was quickly sought, a transwarmer was applied and wet towels removed. The baby was slow to improve despite stimulation, effective inflation breaths and ventilation breaths. The heart rate remained above 60bpm throughout, then at 10 minutes that wonderful all important cry was heard (easily the most beautiful noise in neonatology!)
We stopped the sim and reflected on the learning points raised, particularly the importance of…
Staying calm under pressure
Staying dry under towels
Staying warm under more towels
Staying focused on the airway
Staying off the chest at first
Oh, and calling for help early!
So, for those uninitiated regarding newborn resuscitation, let’s review the basics…
The Basics of NLS
Step 1: dry and stimulate baby (be thorough but don’t spend too long, get rid of wet towels and replace with new ones)
Step 2: position airway neutrally, with bag valve mask provide FIVE effective (but gentle) inflation breaths to achieve chest rise
Step 3: if Step 2 is NOT effective then consider these common mistakes…
Poor position: head not in neutral position, either neck too flexed or extended
Poor seal: mask size is too big/small, slipping low over chin, slipping high over eyes
Poor airway: consider obstruction, suction if anything visible. Put in Guedel and try again.
Poor ventilation: regards the squeezing of the bag (bag mask ventilation) remember not too hard, not too soft. Always use air initially and switch to oxygen later if needed.
Poor grip: it can be tricky if you’re not used to jaw-thrusting or chin-lifting a baby. The idea is to lift the face into the mask and apply the mask down onto the face. If you are struggling then consider a two-handed technique and get others to give ventilations.
Step 4: once chest rise is clearly demonstrated but baby NOT breathing spontaneously then proceed to providing continuous ventilation breaths
Reassess every 30 seconds – colour, tone, breathing, heart rate
Step 5: if AFTER above manoeuvres are effective but baby is still not breathing AND heart rate is less than 60 beats per minute, introduce chest compressions at ratio of 3:1
It’s NEVER wrong to call for help, this means a neonatal crash call.
If in doubt regarding a Step (see above) then repeat it.
Whilst time is critical, you should be slow and steady. When the adrenaline is pumping it is easy to give fast inflation breaths, count 1,2… 2,2… 3,2… 4,2… 5,2 to slow yourself down.
Intubation and umbilical lines are rarely needed if basics are done well.
It’s easy to prioritise chest compressions: DON’T. This is not an adult (see below).
Most important point?
“AB AB AB CDE”
Ventilation is the most effective action in neonatal resuscitation. Avoid commencing chest compressions prematurely as they are likely to compete with the performance and assessment of effective ventilation. Ensure that assisted ventilation is being delivered optimally BEFORE starting chest compressions. Put another way: chest compressions are indicated when the heart rate is <60 bpm despite adequate assisted ventilation for 30 secs (chest wall obviously moving with each inflation). Once compressions are started, they should be continued with as little interruption as possible until there is clear evidence of improvement in spontaneous heart rate.
Even the mild hypothermia (which you may think unimportant) carries a clinically important risk of increased mortality (for each 1°C below 36.5°C mortality increases by 28%)*
*This refers to neonates who require resuscitation and admission to NICU (i.e. a specific population of sick babies).

Learning all of the above is useless if you lose your calm under pressure, if you don’t maintain situational awareness. Which brings us to the topic of thriving under pressure, the topic of mindfulness…
Mindfulness in the ED
What is mindfulness? Simply put, it is paying attention to both the internal and external world, being in the present moment. Alternatively, “it is simply promoting an active awareness of one’s body and thoughts.”
Why should I know about it? It can make you better under pressure, it can be your secret weapon in your next resuscitation! Like going to the gym, it takes practice. It has been compared to being “kettlebells for the brain”. It is only with practice that the enormous benefits can be gained.
How can it help in A&E?
A&E is a unique clinical area where decisions are fast-paced with little time to think. As such, anything that can enhance our ability to think under pressure has to be a good thing? Be it an unexpected emergency or a stressful communication scenario.
Can it really help?
After only 8 weeks we can re-wire our brains! It is suggested on MRI scanning that our amygdala (fear centre) can shrink whilst simultaneously enlargements of our pre-frontal cortex (decision-making centre) can occur. What’s more (with practice) cycling of our thoughts and focus becomes easier and less exertive. Beyond performance in resuscitation, it can enhance resilience and prevent both burnout and compassion fatigue.
Counter effects of stress
Tunnel vision, reduced situational awareness, diminished decision making and impairment of teamwork are a few consequences of “stress.” Fixation is also more likely with less dynamism in your diagnostic process. In short – mitigating these effects whilst maximising the benefits of mindfulness truly has the potential to “super-charge” your clinical practice.
Try these mindfulness tips for your next A&E shift:
Breath (tactical breathing): quietly count in your head, take ten seconds
Talk (self talk): verbalise to yourself, then verbalise to your team
See (visualisation): picture the goal, picture what you want to happen, imagine slowing down
Focus (or any keyword to bring yourself back into the present): the simple act of focusing on your foot steps as you walk to a resus and re-focusing if your mind wanders can bring your physiological and psychological state into balance, making you at your best!
