BEDSIDE ACTION BOX — Delivery & First Hours
- Prepare the "golden hour": warm room, pre-warmed transwarmer/incubator, polyethylene bag/wrap without drying, hat, and a servo-controlled thermal environment — aim to keep axillary temperature 36.5–37.5°C.
- Delayed cord clamping (≥60 seconds) when the infant is stable; start CPAP early and give surfactant per the respiratory pathway if intubated/for RDS.
- Use high ambient humidity in the incubator (very high transepidermal water loss); minimise handling and cluster cares.
- Establish vascular access (UAC/UVC), start maintenance fluids and early parenteral nutrition (from day 1), check glucose, and begin trophic feeds with mother's own milk as soon as feasible.
- Meticulous hand hygiene and aseptic line care from the outset — the biggest preventable harm is infection.
1. Overview
Overview
Very-low-birth-weight (VLBW, <1500 g) and extremely-low-birth-weight (ELBW, <1000 g) infants are physiologically immature across every system. Outcomes are shaped less by any single intervention than by consistent, bundled, preventive care from the first minutes onwards: thermal stability, gentle lung-protective respiratory support, careful fluid/glucose balance, early human-milk nutrition, rigorous infection prevention, and neuroprotective developmental care.
Why This Topic Matters
Admission hypothermia, hypoglycaemia, fluid/electrolyte errors, and late-onset infection each independently worsen survival and neurodevelopment. Getting the "golden hour" and the first days right — a coordinated bundle — is the highest-yield determinant of outcome in this group.
2. Who This Guideline Applies To
Scope
- All infants born <1500 g (VLBW), with particular emphasis on ELBW (<1000 g) and the most immature (<28 weeks).
- Delivery-room stabilisation and the first days to weeks of neonatal intensive care.
- Cross-references: RDS/surfactant (6.1), fluids & electrolytes (7.1), parenteral nutrition (7.2), enteral nutrition (7.3), sepsis (8.1/8.2), IVH (9.2), and jaundice (10.1).
3. Key Definitions
| Term | Definition |
|---|
| LBW / VLBW / ELBW | Birth weight <2500 g / <1500 g / <1000 g. |
| Golden hour | The first ~60 minutes — coordinated stabilisation (thermal, respiratory, glucose, access) linked to better outcomes. |
| TEWL | Transepidermal water loss — very high in immature skin; mitigated by humidity. |
| Neutral thermal environment | Ambient conditions minimising metabolic rate/oxygen use to maintain normal temperature. |
| Trophic feeds | Small-volume enteral feeds to prime the gut without meeting nutritional needs. |
4. The Golden Hour
Coordinated First-Hour Bundle
- Antenatal optimisation: steroids for lung maturity and magnesium sulfate for neuroprotection where indicated; deliver in/transfer to an appropriate unit.
- Thermal: polyethylene wrap without drying, hat, warm room, pre-warmed incubator; servo temperature control.
- Respiratory: delayed cord clamping; early CPAP; surfactant if intubated/for significant RDS; avoid hyperoxia (titrate to target saturations).
- Access & metabolic: umbilical lines, start fluids + early PN, check and maintain glucose.
- Infection & comfort: hand hygiene, aseptic technique, minimal handling, and family involvement.
5. Thermoregulation
Keep Normothermic (36.5–37.5°C)
- Immature infants lose heat rapidly (large surface area, thin skin, little fat) — admission hypothermia increases mortality.
- Use humidified, servo-controlled incubators; plastic wrap and hat in the delivery room; warmed/humidified respiratory gases; minimise cold exposure during procedures.
- Wean humidity gradually as the skin matures over the first weeks; avoid hyperthermia.
6. Respiratory Support
Gentle, Lung-Protective
- Favour early CPAP/non-invasive support to avoid intubation where possible; use surfactant for RDS per the respiratory pathway (see 6.1), including less-invasive administration (LISA) where appropriate.
- Titrate oxygen to the unit's target saturation range; avoid both hypoxia and hyperoxia (ROP/oxidative injury).
- Monitor for apnoea of prematurity (caffeine), and manage the ductus and ventilation strategies to protect the lungs.
7. Fluids & Electrolytes
Principles (full table in 7.1)
- Total fluids on days 0–1, counting PN, line fluids, drugs and flushes: 130 mL/kg/day below 750 g, 110 at 751–1000 g, 80–110 at 1001–1250 g and 80 at 1251–1500 g, reaching 150 beyond day 4. Adjust to weight, urine output and — below 1000 g especially — serum sodium.
- Expect physiological postnatal weight loss; avoid excess fluid (associated with PDA, BPD, NEC) and dehydration/hypernatraemia from high TEWL.
- Delay routine sodium until the postnatal diuresis/natriuresis and initial weight loss; add potassium once urine output is established and hyperkalaemia excluded.
- Monitor electrolytes and glucose frequently in the first days.
8. Glucose
Maintain Euglycaemia
- Preterm infants have limited glycogen/fat stores — start 10% dextrose at 65–80 mL/kg/day (GIR 4.5–5.5 mg/kg/min), then PN at a GIR of 5–7 (some ELBW infants tolerate only 3.5–4.5 at first; see 7.2), and monitor closely.
- Treat hypoglycaemia promptly; watch for hyperglycaemia (common in ELBW) and adjust the infusion rather than reflexively starting insulin — if glucose stays above 280–300 mg/dL, reduce the GIR to 3.5 first.
9. Early Nutrition
Start Early — Parenteral + Enteral
- Begin parenteral nutrition from day 1 (early amino acids and lipids) to limit the postnatal nutrient deficit (see 7.2).
- Start trophic enteral feeds early with mother's own milk (or donor milk) and advance as tolerated; human milk reduces NEC and infection (see 7.3).
- Use a human-milk fortifier when indicated to meet the high protein/energy/mineral needs of growth; monitor growth against preterm charts.
- Supplement vitamins, iron (from a few weeks), and other micronutrients per policy.
10. Infection Prevention & Skin Care
Prevention Bundle
- Hand hygiene (WHO 5 moments, bare below the elbow) and aseptic central-line insertion/maintenance bundles; remove unnecessary lines (see 8.2).
- Early mother's-own-milk feeding; antimicrobial stewardship (short courses; avoid prolonged empirical antibiotics).
- Gentle skin care — immature skin is a fragile barrier; minimise adhesives/trauma; maintain humidity; protect from pressure injury.
11. Neuroprotective & Developmental Care
Protect the Developing Brain
- Minimal handling and clustered cares; midline neutral head positioning and avoidance of rapid position/BP swings in the first 72 hours to reduce IVH risk (see 9.2).
- Low light and noise, day–night cycling, supportive positioning/containment, and non-pharmacological comfort for procedures.
- Family-integrated care: skin-to-skin (kangaroo) care, parental presence and participation, and breastfeeding support.
Baylor Ch 2.1 — Admission Orders, Labs and Screening Schedule
The weight definitions, exactly
- Preterm: under 37 completed weeks (259 days).
- Low birth weight 1500 to <2500 g · very low 1000–1499 g · extremely low <1000 g.
- Small for gestational age: below the 10th percentile, or 2 SD below the mean weight for gestation.
- Growth restriction: a deviation from the growth pattern set by second-trimester fetal measurements — a trajectory, not a single number.
| Order | Baylor detail |
|---|
| Environment | A humidified convertible incubator is preferred at BW ≤1250 g or ≤32 weeks, in servo mode with the skin set point at 36.5 °C. If only a radiant warmer is available, add plastic wrap for infants ≤1250 g and always run it servo-controlled. |
| Monitoring | Cardiorespiratory monitor; saturation target 90–95% with alarms at 88–96%; arterial line (umbilical or peripheral) to the blood-pressure monitor. |
| Line keep-open rates | Heparinized saline or sodium acetate: UAC 0.3 mL/h, peripheral arterial line 0.5 mL/h, UVC 0.3 mL/h, PICC 0.5 mL/h. |
| Blood-draw ceiling | 5–10% of total blood volume (90 mL/kg) per day — the limit that keeps phlebotomy from driving anemia. Review scheduled labs on rounds and cancel what isn't needed. |
| Medications |
- Vitamin K 0.3 mg IM at <1500 g; erythromycin eye ointment.
- Caffeine citrate for BW ≤1250 g: 20 mg/kg load, then 5 mg/kg/day (up to 10), started within the first 10 days.
- Vitamin A for BW ≤1000 g where available: 5000 IU IM on Monday, Wednesday and Friday for 12 doses.
- Surfactant and antibiotics by indication.
|
| Timing | Laboratory studies (Baylor Tables 2-1 and 2-2) |
|---|
| 30 min | Glucose screen |
| Admission | Blood gas, CBC with platelets, blood culture — each if appropriate |
| First 24 h | Blood type, Rh and Coombs (confirmatory only if cord blood was sent) |
| 12–24 h | Electrolytes, glucose, BUN and creatinine, by size and metabolic stability |
| 24 and 48 h | Ionized calcium |
| 24 h | Bilirubin panel |
| 24–48 h, then 14 days | Newborn screens — first and repeat |
| Days 1–3 |
- Electrolytes, glucose, BUN, creatinine every 12–24 h.
- Full chemistry with calcium, magnesium, phosphate and ionized calcium every 24 h while on parenteral nutrition.
- Total bilirubin every 24 h, depending on size, bruising, blood group and the pattern of jaundice.
- Hematocrit and platelets every 24–48 h.
|
| Also | Follow up the maternal RPR, HIV, rubella, GBS and hepatitis results |
Screening and discharge follow-up
- Cranial ultrasound on day 7 for every infant <1500 g, and again at term or discharge to look for cystic periventricular leukomalacia. Severe IVH earns serial scans, with the interval set by how it evolves.
- ROP screening for BW ≤1500 g or ≤30 weeks, or 1500–2000 g with a course the neonatologist judges high-risk. If discharge or transfer is considered before the retina matures into zone III, or after ROP treatment, the follow-up examination must be arranged before the infant leaves.
- Hearing screen before discharge, once the infant is medically stable, >34 weeks PMA and in an open crib.
- Developmental follow-up for every infant <1500 g at 4 months adjusted age, with the consultation started before discharge; twin–twin transfusion survivors are referred too.
- Anemia surveillance paced to the infant: every 1–2 weeks in a small sick infant on support, down to monthly or less in a healthy grower. Cluster the sampling with other tests.
- Before discharge: car-seat observation for apnea, bradycardia or desaturation; CPR training offered to parents; RSV prophylaxis ordered as appropriate.
12. Monitoring & Routine Surveillance
| Parameter | Frequency | Why |
|---|
| Temperature | Continuous (servo) | Maintain 36.5–37.5°C. |
| Glucose & electrolytes | Frequent early, then per stability | Hypo/hyperglycaemia; sodium/potassium balance. |
| Weight / fluid balance / urine output | Daily | Guide fluid therapy; avoid over/under-hydration. |
| Growth (weight/length/head) | Regularly on preterm charts | Nutritional adequacy. |
| Cranial ultrasound | Per unit schedule (e.g., early + follow-up) | IVH/PVL surveillance (see 9.2). |
| ROP screening | Per national criteria | Retinopathy of prematurity. |
| Hearing & neurodevelopmental follow-up | Before/after discharge | Early detection and intervention. |
13. Contraindications & Precautions
Safety Cautions
- Do not allow admission hypothermia — it independently increases mortality; equally avoid hyperthermia.
- Avoid hyperoxia (ROP/oxidative injury) and hypoxia — titrate to the target saturation range.
- Avoid fluid overload (PDA, BPD, NEC) and dehydration/hypernatraemia; individualise volumes.
- Do not delay early nutrition (PN day 1; early trophic MOM feeds).
- Rigorous infection prevention and line stewardship; gentle skin/adhesive handling.
- Minimise handling and BP swings in the first 72 hours (IVH risk).
14. Escalation & Family Support
Escalate When…
- Persistent hypothermia, hypo/hyperglycaemia, respiratory deterioration, or signs of sepsis/NEC — senior/NICU input.
- Abnormal cranial ultrasound (IVH/PVL), haemodynamically significant PDA, or ROP requiring treatment — appropriate specialty pathways.
- Feeding intolerance or faltering growth — nutrition team review.
Parent Counselling Points
- "Very small babies need help staying warm, breathing, and feeding while they mature — we bundle this care carefully, especially in the first hour and days."
- "Your milk is powerful medicine — it protects the gut and reduces infection; we'll support you to express early and often, and to hold your baby skin-to-skin."
- "We keep handling gentle and the environment calm to protect the developing brain, and we'll arrange eye, hearing, and development checks."
15. Key Pearls
High-Value Clinical Pearls
- Outcomes hinge on bundled preventive care from the golden hour — not one intervention.
- Prevent admission hypothermia (wrap + hat + warm room + servo control); target 36.5–37.5°C.
- High humidity in the first weeks counters transepidermal water loss; wean as skin matures.
- Start PN on day 1 and early trophic mother's-own-milk feeds; fortify to meet growth needs.
- Titrate oxygen to targets (avoid hyperoxia/ROP); use early CPAP and surfactant for RDS.
- Minimal handling and BP stability in the first 72 h reduce IVH.
16. Common Mistakes to Avoid
| Mistake | Why it harms | Better practice |
|---|
| Drying an ELBW baby before wrapping. | Heat/water loss. | Plastic wrap without drying + hat. |
| Liberal fluids in the first days. | PDA, BPD, NEC. | Individualised, weight/Na-guided fluids. |
| Delaying nutrition. | Nutrient deficit, poor growth. | PN day 1 + early trophic MOM feeds. |
| High/variable oxygen. | ROP, oxidative injury. | Titrate to target saturations. |
| Frequent handling / BP swings early. | IVH. | Minimal handling; midline positioning. |
| Lax line/hand hygiene. | Late-onset sepsis. | Bundles + stewardship (see 8.2). |
