Newborn life support (NLS)

Table of contents

Introduction

This guide provides a structured approach to newborn life support (NLS), including how to set up a resuscitaire and the NLS
algorithm. It has been created to assist healthcare students in preparing for emergency simulation sessions as part of their
training. It is not intended to be relied upon for patient care.
Most neonates tolerate the birth process well and tend to be born in good condition, requiring minimal assistance. However, a
small number of neonates require additional help and support with transitioning from intrauterine to extrauterine life.

Preparation

If it is anticipated that the baby may be born in poor condition, ensure roles are assigned to team members and make sure
there is an allocated scribe who understands the NLS algorithm to document the resuscitation events. Ensure senior help is
sought early if needed.
Important information to gather before delivery includes\:
Reason for neonatal presence at delivery
Single/multiple pregnancy
Gestation of baby
Any signi
If there are any signs of fetal distress/pathological cardiotocograph (CTG)
Any meconium
Any risk factors for sepsis (e.g. prolonged rupture of membranes >24 hours in term baby and >18 hours in preterm baby,
maternal infection, maternal group B streptococcus colonisation)

Setting up the resuscitaire

Neonatal resuscitaire
Power
to turn the light on.
Ensure the resuscitaire is plugged in. Press the power button on the resuscitaire to switch it on. Press the light switch button
Cylinders
Connect air and oxygen ports to the wall (this ensures an unlimited supply). If using oxygen and air cylinders, ensure they are
open (to open use metal key), ensure the cylinders are full, and be mindful that they may become empty during use so have
spares nearby.
Heating
The resuscitaire will automatically go to the pre-warm temperature setting when switched on. Turn the heat setting to manual
and put the heat up to maximum.
Place a few open towels on the resuscitaire to warm up.
Have your hat ready.
Oxygen
Check your oxygen. The blender should be initially set at\:
FiO2 21% if ≥32 weeks gestation
FiO2 21-30% if 28-31 weeks gestation
FiO2 30% if \<28 weeks gestation
To adjust the oxygen, turn the dial to the required oxygen level.
Suction
To check the suction, switch on the gas supply and switch the suction on by turning the switch to the “on” position. Ensure
suction tubing is connected to the resuscitaire and attached to a suction catheter.
Occlude the suction catheter and adjust pressures using the dial. The suction can be turned o
use up the cylinders very quickly.
Airway pressures
To check the airway pressures, switch on the gas supply and ensure the T-piece is connected to the gas outlet on the
resuscitaire. Use an appropriately sized mask depending on the gestation/estimated weight of the baby. Have varying sizes
nearby if needed.
https\://app.geekymedics.com/osce-guides/emergency/newborn-life-support-nls/ 2/611/13/24, 7\:37 PM Guide | Newborn life support (NLS)
To check your pressures, occlude the valve at the end of the T-piece. The needle on the gauge will move, showing your
positive end expiratory pressure (PEEP), which should be at 5.
To adjust the PEEP, turn the dial on the top of the T-piece.
To check your peak inspiratory pressure (PIP), keep the valve at the end of the T-piece occluded, place your thumb over the
top of the T-piece and look at the gauge. The PIP should be at 30 for a term baby and 25 for a preterm baby (\<32 weeks
gestation). This can be adjusted using the airway pressure dial on the resuscitaire.
Ensure you have a stethoscope and a working laryngoscope with varying sized blades (00-1).

Delivery of the baby

As soon as the baby is born, start the timer and note the time of birth.
Aim for 1-minute delayed cord clamping if the baby does not require immediate resuscitation. This is particularly important for
preterm babies for whom early cord clamping can be a harmful intervention.
Rapidly assess the colour, tone, heart rate and adequacy of breathing whilst the baby is attached to the cord. If there are any
concerns, the cord should be clamped sooner, and the baby should be brought over to the resuscitaire for assessment.
The baby’s temperature should be monitored closely after birth and maintained between 36.5 - 37.5 degrees. Ensure the
environment is warm and draught-free.

Term and near-term infants >32 weeks

Dry and stimulate the baby with a warm towel and apply a hat. Remove the wet towel, replace it with a warm, clean towel, and
wrap the baby to keep them warm.
If the baby does not require any resuscitation, place the baby in skin-to-skin with the mother and cover with a dry towel.
If the baby requires resuscitation or support with transition, keep them on the resuscitaire under the radiant heater, and keep
them as covered as possible.
Preterm baby ≤32 weeks
Babies ≤32 weeks gestation should have a hat applied and be placed undried into a sterile polyethylene suit (face should
remain uncovered) under the radiant heater on the resuscitaire.
This creates a greenhouse e
a transwarmer (thermal mattress) to provide extra warmth.

Assessment of the baby

Initial rapid assessment

Stimulate
Stimulation is an important
towel. Whilst drying them with a towel, rub their back and the soles of their feet to stimulate them further, but remember not
to be too vigorous.
Tone & colour
Assess the tone and colour. Babies may be cyanosed immediately after birth, but this should improve within minutes. It can be
di
Babies who are initially very
immediately.
Heart rate
https\://app.geekymedics.com/osce-guides/emergency/newborn-life-support-nls/ 3/611/13/24, 7\:37 PM Guide | Newborn life support (NLS)
The heart rate ideally should be auscultated with a stethoscope\:
Heart rate >100 bpm\: satisfactory
Heart rate \<100 bpm\: if the heart rate doesn’t increase with stimulation or is \<60/undetectable, the cord should be
clamped immediately and the baby brought to the resuscitaire for assessment/intervention
Breathing
Assess breathing\:
Adequate breathing\: if there is established regular breathing or the baby is crying.
Inadequate/absent breathing\: if there is an abnormal pattern, gasping/grunting or absence of breathing

APGAR score

The APGAR score provides a standardised assessment of a newborn at delivery. It is assessed at 1 minute, 5 minutes and 10
minutes of age. It is scored out of 10.
Table 1. Calculating the APGAR score

Newborn life support

Inadequate/absent breathing or HR \<100 despite stimulation

1. Ask for the cord to be clamped immediately unless able to support the baby on the cord
2. Switch on the gas supply on the resuscitaire
3. Bring the baby to the resuscitaire and place under the radiant heater
4. Dry and stimulate the baby
5. Remove any wet towels and replace them with warm, clean towels; put on hat
6. Place the head in a neutral position and maintain an open airway
7. Auscultate the heart rate and assess the breathing
8. Attach a saturation probe to the baby’s right hand (pre-ductal)
9. If the heart rate is still \<100 or if the baby is gasping or apnoeic, proceed to give

In

Ensuring the head is in a neutral position, identify the correct sized facemask for the baby. Position the mask to cover the nose
and mouth (but not the eyes) and ensure an adequate seal by applying gentle downward pressure and lifting the jaw into the
mask.
Give ≥32 weeks gestation). Ensure each breath lasts 2-3 secs. Count
each breath (e.g. 1-2-3, 2-2-3, 3-2-3, 4-2-3, 5-2-3).

Chest compressions

Chest compressions should be commenced if the heart rate remains \<60 or absent following 30 seconds of e
ventilation breaths. Ensure inspired oxygen is set at 100% if requiring chest compressions.
Call for senior help if you have not already done so.
How to perform chest compression
Use a two handed hand-encircling technique for e
Put both your hands around the baby’s chest, with one thumb on top of the other thumb meeting over the sternum in
between the nipples
https\://app.geekymedics.com/osce-guides/emergency/newborn-life-support-nls/ 5/611/13/24, 7\:37 PM Guide | Newborn life support (NLS)
Compress to a 1/3 of the diameter of the chest, allowing full recoil of the chest between compressions
Compressions should be performed at a 3\:1 ratio with 3 compressions to 1 breath; there should be around 15 cycles every
30 seconds
Re-assess every 30 seconds.
Consider securing the airway if the heart rate remains \<60 or absent despite e
compressions for 30 seconds. This can be done by intubating the baby or inserting a laryngeal mask airway, ensuring chest
compressions are interrupted as little as possible.

Vascular access

The umbilical vein should be used for vascular access for the emergency administration of drugs and
A clean insertion technique should be used in an emergency rather than a sterile one. To con
