Guideline 1.2 — Early Stabilization in Unique Populations

Bedside Action Box — Before the Infant is Delivered

Confirm fetal diagnosis, gestational age, estimated weight, antenatal steroids/magnesium status, infection risk, and whether the family has chosen active or comfort-focused care.
Assign named roles: team leader, airway, access, medication, recorder, temperature, surgical/cardiac liaison, and parent communicator.
Agree on cord plan: delayed clamping when safe; early clamping if immediate resuscitation or diagnosis-specific contraindication makes intact-cord care unsafe.
Prepare disease-specific equipment: Replogle/NG tube, sterile bowel bag, intubation supplies, ECG leads, umbilical access, PGE infusion, thoracentesis/paracentesis kits, lesion dressings, latex-free supplies, surfactant, and transport incubator as indicated.
Plan the exit route: NICU bed, operating room or cardiac/surgical center call, retrieval team, and documentation pack.

1. Overview & Why This Topic Matters

Unique-population resuscitation means that the standard newborn resuscitation sequence must be adapted before birth because the diagnosis changes the safest first action. The team should still protect temperature, establish effective ventilation when needed, monitor heart rate and oxygenation, and support circulation — but the route, timing, and specific steps must be modified for each condition.

The safest approach is to start with a multidisciplinary huddle: confirm diagnosis, goals of care, airway strategy, cord plan, thermoregulation strategy, access plan, first tests, likely medication, transport pathway, and the person responsible for updating parents.

Why It Matters	Clinical Consequence	Bedside Implication
The diagnosis can make routine steps harmful.	Mask ventilation can worsen CDH by inflating intrathoracic bowel; poor positioning can kink gastroschisis mesentery; supine pressure can injure an open neural tube defect.	Brief the whole team before delivery and label steps that must be avoided.
The first minutes determine stability for transport and surgery.	Hypothermia, acidosis, poor perfusion, or bowel ischemia may make transfer or surgery unsafe.	Assign one clinician to temperature and perfusion surveillance, not only airway management.
Family goals may change the intervention plan.	Periviable birth and severe anomalies may require either comfort-focused care or a time-limited trial of intensive care.	Document antenatal counselling, agreed limits, and reassessment triggers.
Subspecialists may need to be activated before birth.	Cardiology, surgery, neurosurgery, urology, genetics, transport, ECMO, and palliative care may be time-critical.	Call early; do not wait for the baby to deteriorate.

Definitions

Condition	Practical Definition	Immediate Stabilization Focus
Abdominal wall defect	Gastroschisis: uncovered bowel outside the abdomen. Omphalocele/exomphalos: abdominal contents herniate through the umbilicus inside a protective sac.	Protect viscera, prevent heat/fluid loss, decompress stomach, avoid torsion or mesenteric traction.
Congenital diaphragmatic hernia (CDH)	Diaphragmatic defect with abdominal contents in the chest causing pulmonary hypoplasia and pulmonary vascular disease.	Avoid bag-mask ventilation, intubate early, decompress stomach/bowel, use gentle ventilation.
Duct-dependent congenital heart disease	Critical lesion requiring a patent ductus arteriosus for systemic blood flow, pulmonary blood flow, or mixing.	Avoid closing the duct, start prostaglandin when suspected, balance pulmonary and systemic circulation.
Hydrops fetalis	Fluid accumulation in at least two fetal compartments such as pleural effusion, ascites, pericardial effusion, or skin edema.	Prepare for difficult ventilation, emergency drainage, transfusion, and shock management.
Lower urinary tract obstruction (LUTO)	Fetal bladder outlet obstruction that may cause anhydramnios, pulmonary hypoplasia, renal dysfunction, and electrolyte/acidosis problems.	Prepare for severe respiratory failure and pneumothorax; assess urine output, renal function, and bladder outlet after birth.
Neural tube defect / myelomeningocele	Open or repaired spinal dysraphism with risk of neural injury, CSF leak, infection, hydrocephalus, and neurogenic bladder/bowel.	Protect lesion, avoid latex, prone/lateral positioning, neurosurgical pathway.
Periviable infant	Infant born near the threshold of viability, commonly 22–23+6 weeks in many contemporary frameworks, with highly individualized decisions.	Pre-birth counselling, gentle thermal/respiratory stabilization, and clear goals-of-care plan.

2. Universal Pre-Birth Planning Checklist

Pre-Delivery Huddle Questions

Huddle Question	What to Clarify	Why It Matters
What is the diagnosis?	Is the diagnosis isolated or part of a syndrome? Is there a comfort-care plan?	Associated anomalies may change resuscitation, prognosis, transfer destination, or urgency.
What should we avoid?	Mask ventilation in CDH; excessive traction/twisting of bowel; latex exposure in MMC; high oxygen in duct-dependent lesions; aggressive handling in ELGAN infants.	Avoiding harm is as important as performing interventions.
What is our first airway plan?	CPAP, PPV, immediate intubation, or no respiratory support if comfort care.	The first airway action differs by diagnosis.
What is the initial oxygen strategy?	NRP targets for most infants; lesion-specific targets for some cyanotic heart disease; lower accepted early saturations in CDH only if perfusion and gas exchange are acceptable.	Unnecessary oxygen may worsen some physiologies or accelerate ductal closure.
Who calls consultants?	Cardiology, surgery, neurosurgery, urology, genetics, transport, ECMO, palliative care.	Calls should occur early enough to guide first-hour actions.

3. Risk Factors & Anticipation

Risk Factor / Clue	Why It Matters	Clinical Action
Prenatal diagnosis of CDH	High risk of pulmonary hypoplasia, PPHN, and deterioration with mask ventilation.	Deliver in a capable center when possible; prepare intubation, Replogle, gentle ventilation, pre/postductal monitoring.
Prenatal abdominal wall defect	Exposed bowel/sac is vulnerable to heat loss, dehydration, torsion, rupture, and contamination.	Prepare sterile bowel bag, NGT/Replogle, IV access away from long-line veins, and surgical/transport notification.
Known duct-dependent lesion or abnormal fetal echo	The baby may look vigorous initially but decompensate when the duct closes or if pulmonary/systemic balance is disturbed.	Have ECG, pulse oximetry, IV access, and prostaglandin plan ready; avoid unnecessary oxygen.
Hydrops, large pleural effusion, or ascites	Lung inflation may be mechanically limited; anemia, shock, or arrhythmia may be present.	Have drainage kits, blood, ECG, echo plan, and additional skilled staff present.
Anhydramnios from LUTO	Pulmonary hypoplasia and pneumothorax risk may dominate the transition.	Prepare for early intubation, small pressure increments, transillumination/needle decompression, and early ECMO discussion in selected cases.
Open neural tube defect	Risk of neural trauma, CSF leak, infection, hydrocephalus, latex sensitization, and neurogenic bladder.	Use prone/lateral positioning, sterile moist non-adherent coverage, latex precautions, antibiotics per local policy, and neurosurgical referral.
22–23+6 weeks with intent to treat	Physiologic immaturity makes heat loss, skin injury, IVH, atelectasis, hypoglycemia, and hemodynamic instability likely.	Use a consultant-led, gentle, pre-briefed, time-limited stabilization plan aligned with family goals.

4. Clinical Presentation & Severity

Severity	Clinical Findings	Concern	Immediate Response
Stable but high-risk diagnosis	Good tone/cry or spontaneous breathing; known antenatal anomaly; acceptable heart rate.	Deterioration may occur after transition, with handling, or during transfer.	Proceed with diagnosis-specific protection and early NICU transfer; do not wait for deterioration.
Respiratory compromise	Apnea, gasping, retractions, low saturations, poor chest movement, or high oxygen need.	Inadequate ventilation, pulmonary hypoplasia, air leak, CDH, PPHN, or pleural/ascitic compression.	Prioritize effective ventilation but adapt route: intubate in CDH; CPAP/PPV for most others; consider drainage if hydrops.
Circulatory compromise	Pallor, weak pulses, prolonged capillary refill, metabolic acidosis, rising lactate, low BP, hepatomegaly.	Duct-dependent systemic lesion, anemia, hydrops, sepsis, hypovolemia, or obstructed venous return.	Call consultant; obtain access; blood gas/lactate; consider PGE, blood, fluids, inotropes, echo.
Surgical threat	Dusky bowel, twisted mesentery, ruptured omphalocele sac, soiled MMC dressing, CSF leak.	Ischemia, infection, dehydration, neural injury, or need for urgent surgery.	Protect anatomy, call surgical/neurosurgical team immediately, and prepare transfer.

5. Diagnosis & First Tests

Finding / Diagnosis	Initial Bedside Assessment	Key Tests in the First Hour	Red Flags
CDH	Scaphoid abdomen, displaced heart sounds, severe respiratory distress, antenatal diagnosis.	Pre/postductal SpO2, blood gas/lactate, CXR/abdomen, echo when stable.	Deterioration with mask ventilation, high pressures, persistent acidosis, pre/postductal split.
Duct-dependent CHD	Central cyanosis or shock with limited lung findings; weak femoral pulses; differential saturations.	Pre/postductal SpO2, 4-limb BP, gas/lactate, CXR, ECG, urgent echo.	SpO2 <75% despite stabilization, lactate >3 mmol/L, base deficit >5, absent pulses, restrictive atrial septum signs.
Hydrops	Edema, ascites, effusions, pallor, poor ventilation, muffled heart sounds.	CXR, gas/lactate, CBC/blood film, blood group/DAT, Kleihauer if indicated, ECG, echo, infection/genetic tests guided by history.	Ventilation failure due to effusion/ascites, severe anemia, tamponade, arrhythmia, shock.
Abdominal wall defect	Exposed uncovered bowel or sac-covered defect at umbilicus.	Glucose, gas, CBC/culture/clotting as needed, electrolytes, surgical photos if consented.	Dusky bowel, mesenteric twist, ruptured sac, hypothermia, excessive NGT losses.
LUTO	Distended bladder, poor urine stream/output, severe respiratory failure after oligohydramnios.	Blood gas, creatinine/BUN, potassium, renal/bladder ultrasound, urine output, later VCUG/MCUG if PUV suspected.	Anuria, hyperkalemia, metabolic acidosis, pneumothorax, severe pulmonary hypoplasia.
Neural tube defect	Open spinal lesion or post-fetal-repair incision; assess movement, CSF leak, sac integrity.	Cranial ultrasound, OFC, renal ultrasound, baseline labs for surgery, MRI if feasible but do not delay urgent closure.	CSF leak, soiling, latex exposure, rapidly increasing OFC, apnea/bradycardia suggesting Chiari/hydrocephalus.
Periviable infant	Gestational age 22–23+6 weeks, weight, vitality, response to stabilization, parental plan.	Glucose, gas after stabilization, temperature, line placement, CXR if intubated, infection risk labs per policy.	Hypothermia, skin injury, poor HR response despite ventilation, severe bradycardia, non-response to agreed trial.

6. Management — Condition-Specific Pathways

6.1 Abdominal Wall Defects: Gastroschisis & Omphalocele

Key Rules

Do: Keep bowel/sac warm, moist, visible, and supported.
Do: Decompress stomach early with NGT/Replogle and leave to drainage.
Do: Position to avoid mesenteric tension or kinking; reassess bowel color frequently.
Avoid: Prolonged mask ventilation, tight wrapping, traction on bowel, umbilical lines, and clamping too close to the defect.

Clinical Situation	Recommended Action	Important Notes
Known gastroschisis (antenatal)	Prepare sterile bowel bag, NGT/Replogle, warm environment, IV access, fluid bolus plan, antibiotics per local surgical pathway, transport call.	Exposed bowel loses heat and fluid rapidly; transfer to surgical center is time-sensitive.
Gastroschisis after birth	Dry upper body, protect lower body and bowel, decompress stomach, support bowel on side of defect, keep bowel visible, monitor perfusion every 15 minutes until definitive surgical care.	Dusky bowel, persistent twist, or poor capillary refill is a surgical emergency.
Omphalocele/exomphalos	Assess sac, clamp cord away from defect, protect sac without rupture, supine nursing unless otherwise advised, NGT drainage, IV access, surgical discussion.	High association with cardiac/chromosomal anomalies; transfer urgency may be less than gastroschisis unless sac ruptures or baby unstable.
Respiratory depression	Support ventilation as needed, but avoid prolonged mask ventilation; intubate if repeated or prolonged PPV is needed.	Air swallowing can distend bowel and worsen respiratory mechanics or mesenteric perfusion.

6.2 Congenital Diaphragmatic Hernia (CDH)

CDH Red Flags

Do NOT give routine bag-mask ventilation in antenatally known CDH.
Avoid high peak pressures and large tidal volumes; permissive hypercapnia is acceptable only when pH, lactate, perfusion, and urine output are acceptable.
Expect PPHN and ventricular dysfunction; echo and pre/postductal monitoring are central to management.
Surfactant is not routine for CDH; discuss with regional center if preterm RDS is suspected.

Step	Action	Target / Rationale
At delivery	Experienced airway operator present; immediate intubation for known CDH; confirm with ETCO2; place Replogle/large NGT to suction/free drainage.	Prevent gastrointestinal distension in the chest and establish controlled ventilation.
Initial ventilation	Use gentle conventional ventilation when feasible: low tidal volume strategy, low PEEP, and avoid PIP >25 cm H2O when possible.	Protect hypoplastic lung from volutrauma/barotrauma.
Oxygen targets	After transition, commonly aim preductal SpO2 80–95% and postductal >70%; avoid hyperoxia.	High oxygen exposure may not improve pulmonary vascular disease and may increase oxidative injury.
Gas targets	Accept permissive hypercapnia if pH remains >7.20 and perfusion/lactate/urine output are reassuring.	Avoid aggressive ventilation solely to normalize CO2.
Pulmonary hypertension	If high FiO2/MAP requirement or significant pre/postductal split, involve tertiary team; consider iNO per local PPHN/CDH pathway.	CDH-related PPHN often requires specialist guidance and sometimes ECMO assessment.
Transfer/surgery	Stabilize first: normothermia, acceptable BP, lactate improving, low-pressure ventilation, controlled oxygen need.	Delayed repair after physiologic stabilization is standard in many centers.

6.3 Duct-Dependent Congenital Heart Disease

Bedside Action — Suspected Duct-Dependent Lesion

Call neonatal consultant and cardiology/transport early.
Measure right-hand and lower-limb SpO2; obtain blood gas with lactate, 4-limb BP, ECG/CXR, and echo when available.
Start prostaglandin if duct-dependent disease is suspected and echo is delayed or diagnosis is uncertain.
Use oxygen judiciously. In known duct-dependent cyanotic lesions, stable SpO2 around 75–85% may be acceptable according to cardiology plan.

Physiology	Presentation	Initial Management
Mixing lesion (e.g., TGA)	Cyanosis often out of proportion to respiratory distress.	PGE; urgent echo/cardiology; assess atrial septum; prepare for septostomy if restrictive.
Duct-dependent pulmonary blood flow	Cyanosis, low saturations, often relatively clear lungs.	PGE to maintain pulmonary blood flow; avoid unnecessary intubation if stable; oxygen for severe hypoxemia.
Duct-dependent systemic blood flow	Shock, weak femoral pulses, acidosis/lactate, sometimes after initial asymptomatic period.	PGE, cautious fluid bolus, inotropes with cardiology guidance, avoid hyperventilation/hyperoxia that increases pulmonary steal.
High pulmonary flow / HLHS or left-sided obstruction	Near-normal or high saturations with worsening acidosis, low diastolic BP, cool peripheries.	Balance Qp/Qs: cardiology call, avoid excess oxygen, consider ventilation strategy and vasoactive support.

6.4 Hydrops Fetalis

Problem	Action	Key Note
Pleural effusion or ascites limits ventilation	Intubate if needed; drain pleural/ascitic fluid if chest rise/HR cannot improve despite adequate airway technique.	Have thoracentesis/paracentesis kits opened before delivery.
Severe anemia or blood loss	Use emergency O-negative, CMV-negative, irradiated blood when indicated; then obtain grouped/crossmatched blood.	Anemia correction may be lifesaving but avoid rapid overload unless actively resuscitating shock.
Shock/poor perfusion	Invasive BP if possible; echo/ECG; inotropes and fluids guided by cause and perfusion.	Hydrops may be hypovolemic, cardiogenic, obstructive, or arrhythmic.
Unknown etiology	Directed work-up: CBC/blood film, DAT, Kleihauer, LFT/albumin, renal/electrolytes, ECG, echo, placenta pathology, chromosomal/microarray, infection testing.	Broad testing should still be clinically organized.

6.5 Lower Urinary Tract Obstruction (LUTO) / Pulmonary Hypoplasia

Situation	Recommended Action	Important Notes
Expected severe pulmonary hypoplasia	Counsel parents before birth about high risk of death despite active treatment; prepare intubation, ECG, transillumination, thoracentesis, and senior airway support.	Response to ventilation may be limited by lung size rather than technique.
Bradycardia or apnea at birth	Follow NRP but move early to a secure airway; use small pressure increments while watching for pneumothorax.	Very high pressures can cause air leak in hypoplastic lungs.
Persistent severe hypoxemia	Consider HFOV, iNO, urgent tertiary/ECMO discussion where appropriate and consistent with goals.	ECMO candidacy varies by center and by pulmonary/renal prognosis.
Postnatal renal risk	Monitor urine output/stream, weight, potassium, bicarbonate/base deficit, creatinine; obtain renal/bladder ultrasound and urology consultation when obstruction suspected.	Hyperkalemia, acidosis, or anuria needs urgent escalation.

6.6 Neural Tube Defect / Myelomeningocele

Red Flags in Open Neural Tube Defect

Never place the infant directly supine on the lesion unless no other position is possible for life-saving resuscitation.
Avoid latex exposure from the delivery room onward.
Keep the lesion protected, moist, non-adherent, and free from stool/urine contamination.
Do not delay urgent neurosurgical consultation for imaging if the lesion is open and closure is needed.

Step	Action	Why
Position	Prone or lateral positioning; use a doughnut/offloading support only if temporary supine resuscitation is required.	Prevents pressure injury to neural elements.
Cover lesion	Use non-adherent sterile interface plus saline-moistened sterile gauze and protective wrap per local neurosurgical protocol.	Reduces drying, tearing, CSF leak, and infection.
Infection prevention	Begin antibiotics according to open lesion/local early-onset sepsis pathway; give vitamin K.	Open lesion is a route for infection and surgery is likely.
Hydrocephalus surveillance	Baseline cranial ultrasound, daily head circumference and fontanelle assessment until definitive plan.	Hydrocephalus may be present or evolve rapidly.
Urologic pathway	Confirm urine and stool passage; renal ultrasound and urology/urodynamic follow-up as indicated.	Neurogenic bladder/bowel may affect renal outcome.

6.7 Periviable Infant: 22+0 to 23+6 Weeks

Core Principles for Periviable Delivery

Use joint obstetric-neonatal counselling and document the plan before birth whenever possible.
Avoid using gestational age alone; include estimated weight, sex, singleton/multiple status, antenatal steroids, fetal growth restriction, infection, anomalies, and parental goals.
A trial of intensive care should include reassessment points and compassionate communication if the infant does not respond.
Comfort-focused care is active care: warmth, privacy, analgesia/comfort, memory-making, and family support.

If Survival-Focused Care is Chosen	Practical Stabilization Approach
Thermoregulation	Pre-warm room/warmer; use plastic wrap/bag without drying body; hat; thermal mattress; warmed/humidified gases when available.
Cord management	Consider delayed cord clamping 30–60 seconds if consistent with maternal/baby stability and the plan; do not allow cord management to delay essential resuscitation.
Ventilation	Use the lowest pressures that produce chest movement and rising HR; initial PIP ~20 cm H2O and PEEP ~5 cm H2O may be adequate but must be individualized.
Airway/surfactant	If poor response, intubate gently with experienced operator; give surfactant after confirming tube position when intubated for RDS/extreme prematurity per policy.
Vascular access	Minimize skin trauma; use umbilical lines early if proceeding with intensive care; begin dextrose fluids promptly.
Handling	Use minimal stimulation, clustered care, neutral head position, and careful documentation of response.

7. Medication Table

Medication / Fluid	Use in This Chapter	Common Dose Range	Monitoring	Important Cautions
Dinoprostone (PGE2) / Alprostadil (PGE1)	Suspected or confirmed duct-dependent systemic or pulmonary blood flow, or critical mixing lesion.	Local dosing commonly 5–50 nanogram/kg/min for PGE infusion; higher doses only with specialist guidance.	HR, BP, RR/apnea, SpO2, temperature, glucose, lactate, blood gas, IV site.	Apnea and hypotension; use reliable access and prepare for intubation if recurrent apnea or high dose.
Normal saline 0.9%	Shock, poor perfusion, suspected hypovolemia, abdominal wall defects with high fluid losses.	10 mL/kg bolus; reassess before repeating.	Perfusion, BP, lactate, urine output, sodium/chloride, edema.	Avoid repeated uncritical boluses, especially in preterm infants, CDH, and cardiac lesions.
O-negative emergency blood	Severe anemia or suspected fetal-maternal hemorrhage in hydrops/resuscitation.	Per local massive transfusion/neonatal transfusion protocol.	Hb/Hct, perfusion, calcium, glucose, temperature, potassium, acid-base.	Use CMV-negative/irradiated products when required; avoid delay in life-threatening anemia.
Morphine infusion	CDH or ventilated infant requiring analgesia/sedation after stabilization.	Often 10–20 microgram/kg/hr; use local formulary and adjust for gestation/organ function.	BP, ventilation, CO2, bowel function, neurologic exam, withdrawal if prolonged.	Avoid deep sedation and hypotension; avoid routine paralysis in initial CDH unless specialist-directed.
Surfactant	Intubated extremely preterm infant or preterm RDS; not routine for isolated CDH.	Product-specific dose; follow local formulary.	SpO2/FiO2, CO2, chest movement, CXR if needed, tube position.	Avoid over-distension; reconsider if primary problem is CDH/PPHN rather than surfactant deficiency.
Antibiotics	Open abdominal wall/NTD, suspected infection, surgical transfer, hydrops with infectious concern.	Regimen follows local EOS/surgical pathway and renal function.	Cultures, CBC/CRP where used, renal function, drug levels for aminoglycosides.	Avoid delaying urgent surgical/cardiac stabilization for antibiotics, but give promptly once access is obtained.
Vitamin K	All newborns, including surgical anomalies and preterm infants.	Dose per local neonatal policy; lower-dose policies may apply to very-low-birth-weight infants.	Bleeding risk, documentation before transfer/surgery.	Must be documented clearly before transfer.

Baylor Ch 1.2 — Delivery-Room Plans by Condition

Where early death is a real possibility, the neonatal, obstetric and family teams should agree goals of care before delivery, so that all three expectations match.

Condition	Delivery-room plan
Abdominal wall defects	Gastroschisis is usually isolated but may come with atresia or perforation; omphalocele often carries other anomalies and genetic conditions. Decompress the stomach and bowel and protect the exposed contents. Consider delayed cord clamping. Put the lower body in a sterile bowel bag; avoid positive pressure unless needed. In gastroschisis, position on the side to stop the mesentery kinking and the bowel becoming ischemic. Replogle to suction, peripheral IV, transfer.
Congenital diaphragmatic hernia	Intubate immediately — no bag-mask ventilation, which inflates bowel inside the chest. Do not delay cord clamping. Prepare the transport ventilator with monitor, intubation kit (cuffed tube after fetal tracheal occlusion) and a Replogle. Initial settings: tidal volume 4–5 mL/kg, PEEP 5–6, rate 40, inspiratory time 0.3 s, Pmax 28, FiO₂ 100%. Replogle to suction, peripheral IV, transfer.
Congenital heart disease	Review the fetal echo: what depends on ductal patency, ventricular function, chamber sizes. Have ECG leads and umbilical line equipment ready. A baby with critical disease can look vigorous at birth. Target saturations by physiology, not the NRP curve, when there is intracardiac shunting — extra oxygen can close the ductus the infant depends on, so avoid it unless needed for stabilization. Once cardiorespiratory status is stable, start prostaglandin through a peripheral or umbilical venous line.
Hydrops	Fluid in two or more compartments; mortality roughly 50–90%, and up to 90% of cases today are non-immune. Prepare parents for death in the delivery room or NICU. Have intubation supplies, ECG, and two thoracentesis and two paracentesis kits, plus extra skilled hands. Effusions or ascites can prevent lung inflation — draining them may be what finally lifts the heart rate. ECG helps when effusions muffle heart sounds. Consider surfactant in preterm infants; obtain a peripheral IV, or a sterile UVC if skin edema blocks peripheral access.
Lower urinary tract obstruction	Anhydramnios causes pulmonary hypoplasia; severity is hard to judge before birth, but longer anhydramnios and earlier gestation predict worse lungs. Have intubation supplies, ECG, a transilluminator and two thoracentesis kits ready. Move early to intubation if the heart rate is low, raising pressure in small steps — but watch for pneumothorax, auscultating or transilluminating often. Saturations may be unreachable without HFOV or iNO; if hypoplasia looks severe, ask the ECMO team early whether they would cannulate.
Neural tube defect	Consider delayed cord clamping. Position prone; if supine is needed for resuscitation, support the defect on a doughnut cushion. Check for CSF leak, or the surgical repair if closed in utero. No latex. Cover the defect with saline-soaked sterile gauze, hold it with loosely wrapped dry gauze, and use a diaper or mud flap to keep stool away, then place the lower body in a sterile bag.

Gestation (Baylor Table 1-2)	Approach to resuscitation
<22 0/7 weeks	Comfort care
22 0/7 – 23 6/7 weeks	Comfort care and assessment for a trial of resuscitation, offered in line with the parents’ wishes
≥24 0/7 weeks	Resuscitation recommended
This framework assumes an appropriately grown infant without major complications or multiple anomalies; multiple gestation, severe growth restriction, malformations or hydrops all change it.

Resuscitating at 22–23 weeks

Why they are fragile: immature skin, little subcutaneous fat, a large surface-to-mass ratio, weak muscles, stiff surfactant-deficient lungs, fragile cerebral vessels and almost no metabolic reserve.
Before delivery: agree goals with the obstetric team and parents; resuscitation may be offered as a trial, and chest compressions and epinephrine may reasonably be excluded as futile depending on the baby's condition at birth. Confirm antenatal steroids, the cord plan and cord blood typing.
Prepare the room: pre-warm it to 75 °F, pre-warm the radiant warmer, ready a plastic bag and an activated chemical mattress, cardiac monitor and ECG leads, intubation supplies, surfactant, umbilical lines, and a pre-warmed transport incubator and ventilator. Hold a huddle that assigns roles and emphasizes gentle handling.
At birth: delayed clamping for 30–60 s while the infant goes into the bag.
Ventilate with the T-piece at the lowest pressures that work — PIP 20, PEEP 5 — starting at FiO₂ 50%.
Intubate after stabilization, or sooner if the heart rate stays below 100 on mask ventilation: tube depth 5–6 cm, then surfactant 2.5 mL/kg once position is confirmed.
Move to the transport ventilator quickly to limit manual breaths. Skip the peripheral IV — it costs skin — and go to umbilical lines, then start dextrose as soon as they are secured.
Watch temperature throughout, and keep the parents informed.

8. Monitoring

Parameter	Frequency	Target / Concern	Action if Abnormal
Temperature	At birth, NICU admission, then per acuity	36.5–37.5°C unless therapeutic hypothermia pathway applies.	Escalate warming/cooling strategy; review ambient temperature, wrap, mattress, humidified gases.
Heart rate / ECG	Continuous during stabilization	Rising HR is the key sign of effective ventilation; arrhythmias in hydrops/CHD.	Optimize ventilation first; evaluate ECG rhythm; call cardiology if arrhythmia/PEA suspected.
Pre/postductal SpO2	Continuous for CDH, CHD, PPHN, hydrops	Use NRP targets generally; disease-specific goals for CDH/duct-dependent lesions.	Titrate oxygen carefully; evaluate ductal physiology, PPHN, ventilation, pneumothorax, and perfusion.
Blood gas + lactate	Early after stabilization and then q1–4h by acuity	pH, CO2, oxygenation, lactate trend; lactate >3–5 mmol/L suggests perfusion concern depending on context.	Review ventilation, cardiac output, anemia, duct patency, shock, sepsis, and fluids/inotropes.
Blood pressure	Continuous arterial if unstable; otherwise frequent cuff	Mean BP appropriate for GA and perfusion status.	Cautious fluid bolus, echo, inotropes/vasoactives with consultant/cardiology guidance.
Glucose	Early, then q1–6h by risk	Hypoglycemia risk in periviability, hydrops, stressed infants, prolonged resuscitation.	Bolus/infusion per NICU hypoglycemia policy; secure access.
Urine output	Hourly if catheterized/critically ill; otherwise each diaper	≥1 mL/kg/hr in many stabilized critical infants; anuria/poor stream in LUTO.	Check renal function/electrolytes; bladder scan/ultrasound; urology/nephrology consultation.
Bowel/defect perfusion	Every 15 min until surgical transfer/stability	Pink, perfused, untwisted bowel; intact sac.	Reposition/support, loosen wrap, call surgeon if dusky, twisted, or ruptured.
Neural lesion integrity	At birth then at least q4h or per neurosurgery	Moist non-adherent coverage, no soiling, no CSF leak progression.	Replace/remoisten dressing; urgent neurosurgery if soiled, leaking, or damaged.
Family updates	Initial huddle, after stabilization, before transfer, after major change	Clear, compassionate, consistent message.	Assign communicator and document discussion.

9. Practical Bedside Algorithms

Algorithm A — Universal High-Risk Delivery Adaptation

Review antenatal diagnosis, fetal echo/ultrasound findings, gestational age, weight estimate, infection risk, and parental goals of care.

Brief the team using diagnosis-specific 'must do' and 'must avoid' statements.

Prepare thermoregulation, airway, access, medication, procedure, imaging, and transfer equipment before delivery.

At birth, maintain temperature and assess tone, breathing, and heart rate while following the agreed cord plan.

Use the safest airway route for the diagnosis: CPAP/PPV for most infants, immediate intubation for known CDH, lesion protection for NTD, and no invasive respiratory support for comfort-focused care.

Obtain early monitoring: ECG, right-hand SpO2, lower-limb SpO2 where relevant, temperature, BP, glucose, and gas/lactate.

Start first-line diagnosis-specific management: Replogle/NGT, PGE, bowel/lesion protection, drainage, surfactant, fluids/blood, or urology/neurosurgery plan as indicated.

Reassess response every few minutes in the delivery room and at NICU arrival; escalate to consultant, subspecialist, and retrieval team early.

Document objective findings, interventions, response, medication doses, family discussions, and transfer plan.

Algorithm B — CDH Stabilization

Known or strongly suspected CDH: call senior airway operator; avoid routine mask ventilation.

Intubate promptly; confirm position clinically and with ETCO2; secure tube.

Place Replogle/NGT and decompress stomach/bowel; keep on suction/free drainage per local pathway.

Start gentle ventilation with low pressures and avoid aggressive normalization of CO2.

Place preductal and postductal SpO2; obtain gas/lactate, CXR, echo when stable.

If oxygenation or perfusion worsens: check tube/NGT, pneumothorax, PPHN, RV function, lactate, BP, and call tertiary/transport/ECMO team as appropriate.

Transfer only after stabilization goals are met or with retrieval team guidance if deterioration continues.

Algorithm C — Suspected Duct-Dependent Cardiac Lesion

Recognize cyanosis with little respiratory distress, shock, weak femoral pulses, differential saturations, or abnormal fetal echo.

Attach right-hand and lower-limb SpO2, ECG, and BP; obtain gas/lactate and glucose.

Call neonatal consultant and cardiology/transport; arrange echo urgently.

If duct-dependent lesion cannot be excluded, start prostaglandin through reliable IV access per local dosing pathway.

Avoid unnecessary oxygen and hyperventilation in known balanced/cyanotic lesions; treat severe hypoxemia or shock while awaiting echo.

If apnea after PGE or severe acidosis/shock: intubate and ventilate; do not stop ductal support without cardiology advice.

Prepare for urgent cardiac intervention if restrictive atrial septum, TGA with poor mixing, or ductal shock is suspected.

10. Escalation Criteria

Escalate Immediately If…	Who to Call	Why
CDH with FiO2 >0.60 or high pressure/MAP requirement, worsening lactate/acidosis, pre/postductal split, or suspected air leak	Neonatal consultant, regional CDH/PPHN center, retrieval/ECMO team	Potential need for advanced ventilation, pulmonary vasodilator strategy, ECMO assessment, or urgent transport.
Cardiac baby with shock, lactate >3 mmol/L, base deficit >5, SpO2 <75%, weak/absent femoral pulses, or restrictive atrial septum signs	Cardiology, neonatal consultant, cardiac transport	Ductal closure or poor mixing can rapidly become fatal.
Gastroschisis bowel becomes dusky, twisted, cold, or poorly perfused	Pediatric surgeon and transport immediately	Possible mesenteric ischemia.
Open MMC is leaking, soiled, drying, or deteriorating neurologically	Neurosurgery	Risk of infection, neural injury, and hydrocephalus.
Hydrops infant cannot ventilate despite airway correction or has massive effusion/ascites	Neonatal consultant plus procedural operator; cardiology if effusion/tamponade	Drainage may be required to achieve ventilation/circulation.
Periviable infant has persistent severe bradycardia despite effective ventilation within the agreed trial	Consultant neonatologist and family communicator	Requires rapid reassessment of goals and proportionality of intervention.

11. Conflicting Evidence / Areas Where Practice Varies

Clinical Question	Recommendation A	Recommendation B	Practical Interpretation
Periviable resuscitation at 22–23 weeks	Some frameworks offer comfort care or a trial of resuscitation aligned with parental goals at 22–23+6 weeks.	Some units use more conservative or more proactive thresholds depending on outcomes and resources.	Use an individualized, documented plan; local outcome data, antenatal steroids, fetal growth, sex, plurality, anomalies, and parental goals matter.
Delayed cord clamping in complex anomalies	DCC may be considered when the baby is vigorous and immediate intervention is not required.	CDH, gastroschisis, severe hydrops, and immediate resuscitation often prompt early clamping to permit urgent stabilization.	Do not let cord management delay life-saving or diagnosis-specific intervention; huddle with obstetrics.
Cord milking	Reasonable in some ≥28 week infants if DCC cannot be performed, and in nonvigorous ≥35 week infants in some guidance.	Not recommended below 28 weeks because of severe IVH concern.	Follow current AHA/AAP/NRP and local policy; avoid UCM in <28 weeks.
Initial respiratory support for extremely preterm infants	CPAP-first is standard for many spontaneously breathing preterm infants.	Some centers intubate very immature infants early for surfactant and controlled ventilation.	For 22–23 week infants, decide during pre-birth planning; prioritize gentle ventilation and avoid prolonged ineffective mask ventilation.
CDH initial ventilation mode	Gentle conventional ventilation is often preferred first.	HFOV is used when conventional ventilation cannot maintain acceptable gas exchange without unsafe pressures.	Avoid high pressures; involve a CDH/PPHN center early.

12. Common Mistakes

Common Mistake	Why It Is Harmful	Better Approach
Using the standard resuscitation script without diagnosis-specific modifications	Certain routine actions can worsen physiology or anatomy.	Start every high-risk delivery with a huddle and a 'do not do' list.
Bag-mask ventilation in known CDH	Inflates bowel in the chest and worsens ventilation/circulation.	Intubate promptly and decompress with Replogle/NGT.
Chasing normal saturations in duct-dependent cyanotic CHD	Can increase pulmonary blood flow, close ductal physiology, or worsen systemic perfusion.	Use cardiology-specific targets and monitor lactate/perfusion, not SpO2 alone.
Wrapping gastroschisis bowel tightly or failing to support the mesentery	Can compromise bowel perfusion and cause ischemia.	Keep bowel visible, moist/warm, supported, untwisted, and reassessed frequently.
Placing an MMC infant supine on the lesion	Can damage exposed neural tissue or repair site.	Prone/lateral positioning and lesion off-loading.
Delaying consultant/subspecialist calls until after deterioration	Transport, surgery, cardiology, and ECMO decisions need preparation time.	Call early from the delivery-room huddle or immediately after birth.
Over-resuscitating periviable infants beyond the agreed goals without reassessment	May prolong suffering when goals were time-limited or comfort-focused.	Use consultant-led reassessment and family updates at defined decision points.

13. Family Communication

Suggested Parent-Facing Language

Before birth: "Your baby has a condition that changes what we do in the first few minutes. We have a team ready, and we will explain what we are doing as soon as it is safe."
After stabilization: "The first goal was to help your baby breathe and keep the circulation stable. The next goal is to protect the affected organ and move safely to the NICU/specialist team."
For periviability: "We will reassess your baby's response. If treatments are helping, we continue. If they are not helping and are causing suffering, we will talk with you immediately about the most loving and appropriate care."
Before transfer: "The transfer is not because we are giving up; it is because your baby needs a specialist team/equipment that is ready to continue care."

14. Teaching Points

High-Yield Teaching Points

In high-risk fetal diagnoses, the first question is not "What does NRP say?" but "How does the diagnosis change the safest way to achieve NRP goals?"
CDH is an airway-and-gut-decompression emergency; abdominal wall defects are heat-fluid-perfusion emergencies; duct-dependent CHD is a circulation-and-ductal-patency emergency.
A rising heart rate remains the most important sign of effective ventilation, but some diagnoses require ventilation through a different route.
Right-hand SpO2, lower-limb SpO2, lactate, perfusion, and blood pressure are often more useful together than any single number.
Comfort-focused care is not absence of care; it is active, skilled care focused on warmth, comfort, family presence, and dignity.

15. High-Yield Summary

Key Takeaways

Plan before birth: diagnosis, goals, equipment, roles, consultant calls, and transfer route.
Avoid harmful routine actions: bag-mask ventilation in CDH, tight bowel wrapping, latex exposure in MMC, and indiscriminate oxygen in duct-dependent CHD.
Use disease-specific stabilization targets while maintaining universal priorities: temperature, ventilation, heart rate, perfusion, glucose, and communication.
Escalate early; unique populations deteriorate quickly and often need surgical, cardiac, neurosurgical, urologic, genetic, transport, ECMO, or palliative input.
Document the plan, the response to care, and family communication clearly.
