Unexpected Preterm Birth

When a preterm baby arrives sooner or smaller than planned: who stays at Gosford, how to prepare, the first 10 minutes, and the first hour. Warmth, gentle breathing support and calling for help early.

FIRST, THE BIG PICTURE

Who stays at Gosford?

Gosford SCN cares for babies from 32 weeks. Below that, the baby needs a NICU. Above it, many babies stay with us, but not all.

BabyWhere they belongNETS?
Under 32 weeksNICUYes - call the consultant, who will call NETS early (ideally before the birth)
32 weeks and over, settlingGosford SCNUsually not needed
32 weeks and over, escalatingDecided by the consultantIf rising oxygen or work of breathing on CPAP, needs ventilation, or is otherwise unwell

22-23 weeks (periviable)Whether to resuscitate is decided by the consultant with the familyYes, if active care is planned
Whether to call NETS is the consultant’s decision. Your job is to call the consultant early and have the information ready.

BEFORE THE BIRTH

Use every minute you have

Even five minutes of preparation changes how the first hour goes.

Call early

Call the consultant as soon as you hear about a preterm labour, not when the baby is born.

Ask the obstetric team whether in-utero transfer is still possible. Transferring the mother is safer than transferring the baby.

Check the antenatal story

Gestation and estimated weight. Steroids given, and when? Magnesium sulfate (under 30 weeks)?

Infection risk: ruptured membranes, maternal fever, GBS status, antibiotics in labour. Any known fetal concerns.

Prepare Ruby and the room

Warm the room and turn on the warmer. The preterm pack is in the bottom drawer of Ruby.

Plastic bag and hat, small masks, T-piece with PEEP, blender set to 30%, sats probe, 2.5 and 3.0 ETTs, surfactant if likely, glucose, UVC kit.

Allocate roles

Leader, airway, sats and heart rate, timer and scribe. Brief the team on the plan before the baby arrives.

If time allows, the consultant meets the parents first.

If the birth is imminent and the consultant has not arrived, start without them and keep them updated by phone.

AT BIRTH

The first 10 minutes

The same sequence as any birth (see Attending a Birth), with a few preterm changes.

1

Delay cord clamping

If the baby is stable, wait at least 30-60 seconds before clamping. Do not milk the cord under 28 weeks.

2

Keep warm - do not dry THE QUICK WIN

Under 32 weeks: straight into the plastic bag, add a hat, under the warmer. Aim for 36.5-37.5°C.

3

Sats probe and heart rate

Probe on the right wrist. Listen to the heart rate or use ECG leads if sats are slow to pick up.

4

Support breathing gently

If breathing: CPAP (PEEP 5-8) via T-piece. If not breathing or HR under 100: mask ventilation with PEEP and the lowest pressure that moves the chest.

5

Titrate oxygen

Start at 21-30% and titrate to the SpO2 targets. Avoid hyperoxia.

6

Not improving?

Recheck mask seal and airway first. Then call senior help to intubate.

Most preterm babies need help to breathe, not resuscitation. Effective CPAP and warmth solve most first-10-minute problems.

ON THE SCN

The first hour

Stabilise while you wait for transfer, or settle the baby for an SCN stay.

Temperature

Check on arrival in the SCN and repeat until stable. Use a humidified incubator or warmer.

Cold and too-hot babies both do worse.

Breathing and surfactant

CPAP is first-line. Get a chest X-ray and blood gas.

Consider surfactant if oxygen need rises above about 30% on CPAP. Gosford uses LISA or INSURE, depending on the consultant.

Glucose and fluids

Check the glucose within the first hour. Preterm babies have low stores.

PIVC and IV 10% glucose at the local starting rate. UVC if access is difficult or retrieval is planned.

Infection

Unexplained preterm labour can be a sign of infection.

If there are risk factors or the baby is unwell: blood culture, then IV antibiotics per local guideline.

Write it down as you go: times, observations, oxygen, and what you gave. It forms the handover.

IF NETS IS COMING

What NETS will ask

Have this ready before the call. The consultant will usually make it.

TopicHave ready
BabyGestation, weight, time of birth, condition at birth, Apgars
BreathingSupport (CPAP or ventilation), pressures, FiO2, latest gas, chest X-ray
CirculationHeart rate, BP, perfusion, access (PIVC or UVC)
OtherTemperature, glucose, antibiotics given, surfactant given
AntenatalSteroids, magnesium, infection risks
FamilyWhat the parents know, and the mother’s condition
Keep stabilising while you wait. Ask NETS for advice at any point.

EXTREME PREMATURITY

Periviability (22-23 weeks)

At 22-23 weeks, whether to offer active resuscitation depends on the baby’s condition and the parents’ wishes. Under 25 weeks, every birth needs a senior.

Senior-led, always

Under 25 weeks, a consultant should attend the birth. At 22-23 weeks, the consultant leads the decision about resuscitation with the family, with NETS involved early.

If you are first at a very preterm birth, keep the baby warm and call for help. See Antenatal for counselling.

Comfort care is care

If the plan is comfort care, keep the baby warm and with their parents.

Support the family and staff afterwards.

THE FAMILY

Parents in the first hour

A preterm birth is frightening and fast. Small things help.

Keep them connected

Let parents see and touch the baby before transfer if possible. Take photos for the mother.

Explain the plan

Explain who is caring for the baby, where they are going, and when they will next hear from the team. Document the conversation.
