BEDSIDE ACTION BOX
- Start PN from day 1 in VLBW/ELBW infants and any neonate who won't reach adequate enteral intake soon — early amino acids and lipids prevent the catabolic nutrient deficit.
- Use standardised (starter/concentrated) PN bags where available to enable immediate, safe day-1 nutrition.
- Provide glucose at an appropriate glucose infusion rate; advance amino acids and lipids to target over the first days while watching triglycerides and glucose.
- Give PN (especially concentrated glucose/calcium) via a central line; peripheral PN must be dilute to avoid extravasation injury.
- Advance enteral feeds in parallel and wean PN as feeds increase; stop PN once feeds are established, per policy.
1. Overview
Overview
Parenteral nutrition delivers intravenous macronutrients (amino acids, lipids, glucose), electrolytes, minerals, vitamins, and trace elements to infants who cannot be fed enterally in sufficient quantity. In preterm infants the priority is to start early — ideally on day 1 — to prevent the rapid accumulation of a protein and energy deficit that impairs growth and neurodevelopment, then to transition to enteral feeding as soon as the gut allows.
Why This Topic Matters
Early amino acids and lipids improve growth and reduce postnatal growth failure; conversely, prolonged PN carries real risks — sepsis (line-related), cholestasis (PN-associated liver disease), metabolic derangement, and refeeding-type disturbances. Getting initiation, targets, and timely weaning right matters.
2. Who This Guideline Applies To
Scope
- Preterm/VLBW/ELBW infants and any neonate who will not achieve adequate enteral nutrition within a short period (e.g., gut surgery, NEC, severe illness).
- Infants being weaned from PN as enteral feeds advance.
- Cross-references: fluids & electrolytes (7.1), enteral nutrition (7.3), VLBW care (2.1), NEC, and line infection (8.2).
3. Key Definitions
| Term | Definition |
|---|
| PN | Parenteral (intravenous) nutrition. |
| GIR | Glucose infusion rate (mg/kg/min) — the standard measure of IV glucose delivery. |
| Standardised PN | Pre-formulated "starter"/concentrated bags enabling immediate day-1 nutrition. |
| PNALD / IFALD | PN-associated / intestinal-failure-associated liver disease (cholestasis). |
| Refeeding syndrome | Electrolyte shifts (low phosphate/potassium/magnesium) on reintroducing nutrition, relevant in growth-restricted infants. |
4. Initiation
Start Early — Day 1
- Begin PN on day 1 in VLBW/ELBW infants using standardised starter bags where available (avoids delay while individualised PN is prepared).
- Start amino acids and lipids from the outset (not glucose alone) — early protein prevents negative nitrogen balance.
- Coordinate the PN volume with the total fluid intake plan (7.1); as enteral feeds start, reduce PN to keep the total on target.
5. Macronutrient Targets
Default Preterm PN Targets (Baylor Ed. 33, Table 14-1)
Start on admission and reach goal quickly; starting orders, advancement rules and the lipid start table are in section 6+.
| Component | Start → goal | Notes |
|---|
| Amino acids | 2–3 → 3.5–4 g/kg/day preterm (2–3 term; up to 4 with GI disease, surgery, protein loss or long-term PN) | Add cysteine 30–40 mg per g of amino acid; monitor urea. |
| Lipids | 0.5–2 g/kg/day by birth weight → 3 g/kg/day | Advance only while TG <250 mg/dL. Intralipid first line except with, or at risk of, IFALD (section 8+). |
| Glucose (GIR) | 5–7 (some ELBW infants tolerate only 3.5–4.5) → 10–11 mg/kg/min | Advance by 1–2 while glucose <130–150 mg/dL; if >280–300 mg/dL, reduce GIR to 3.5 before insulin. |
| Energy | 42–57 → 90–100 kcal/kg/day | Balance protein:energy for lean growth. |
| Fluid | Most requirements are met at 130 mL/kg/day of PN | Integrate PN volume with total intake (7.1). |
Other sources: ESPGHAN-based ranges start amino acids at about 1.5–2.5 g/kg/day, lipids at 1–2 (target 3–4) and GIR at 4–8 (advancing to 8–12) mg/kg/min, allow up to about 120 kcal/kg/day, and prefer composite (SMOF-type) emulsions. Use one protocol consistently.
6. Electrolytes, Minerals, Vitamins & Trace Elements
Key Points
- Provide sodium, potassium (timed as in 7.1), and generous calcium and phosphate (and magnesium) for bone mineralisation — monitor for metabolic bone disease of prematurity.
- Add vitamins (fat- and water-soluble) and trace elements per policy; consider phosphate/potassium needs in growth-restricted infants (refeeding risk).
- Be alert to calcium–phosphate compatibility limits in the PN solution (pharmacy-guided).
6+. Starting, Advancing and Stopping PN — Default Protocol (Baylor Ed. 33)
The first hours
- Initial IV fluid after delivery: 10% dextrose at 65–80 mL/kg/day, which gives a GIR of 4.5–5.5 mg/kg/min.
- Start PN on admission for: <1500 g; major congenital heart disease (any infant on prostaglandin or vasopressors); congenital bowel anomalies such as gastroschisis or omphalocele. Consider it for preterm infants ≥1500 g and/or ≥29 weeks expected to need 5–10 days to reach 120 mL/kg/day of feeds.
- Standard starter solution (glucose, 3% amino acids, calcium and water, plus heparin 1 unit/mL; no phosphorus, cysteine, vitamins or trace elements, and it cannot be modified) bridges the gap until custom PN can be compounded. Cap it at 100 mL/kg/day to avoid excess protein, and give any extra fluid as a piggyback. For infants ≤1000 g, run the 10% dextrose starter at 80 mL/kg/day or the 5% dextrose starter at 100 mL/kg/day.
- Custom PN at 0–24 hours: GIR 5–7 mg/kg/min, amino acids 2–3 g/kg/day, calcium and phosphorus 1–1.2 mmol/kg/day, magnesium 0.5 mEq/kg. Include phosphorus within the first 24 hours. Sodium or potassium comes with the phosphate salt; extra NaCl and KCl are generally not needed. Start lipid with PN or within 24 hours — protein and fat alongside glucose help glucose control.
| Nutrient (Baylor Table 14-1) | At initiation | Goal for growth |
|---|
| Energy | 42–57 kcal/kg | 90–100 kcal/kg |
| Protein | 2–3 g/kg | 3.5–4 g/kg preterm; 2–3 g/kg term (up to 4 g/kg with GI disease, surgery, protein loss or long-term PN) |
| Fat | 0.5–2 g/kg | 3 g/kg |
| Glucose | 5–7 mg/kg/min | 10–11 mg/kg/min |
| Calcium / phosphorus | 1–1.2 mmol/kg each | 1.5–2 mmol/kg each, 1:1 molar ratio |
| Sodium / potassium | 0 (arrives with phosphate) | 2–4 mEq/kg each |
Calculations (Table 14-2): GIR (mg/kg/min) = dextrose % × volume (mL/kg/day) ÷ 144 — for example, D10 at 80 mL/kg/day gives 5.6 mg/kg/min. Baylor prints the divisor as 1.44, which is correct only if the concentration is entered as a decimal (0.10 for 10%). Entering the whole-number percentage with ÷1.44 overstates the GIR 100-fold. Energy: dextrose 3.4 kcal/g, protein 4 kcal/g, 20% lipid 2 kcal/mL (5 mL = 1 g fat). Conversions (Table 14-3): calcium 1 mmol = 2 mEq = 40 mg; phosphorus 1 mmol = 31 mg; sodium 23 mg, potassium 39 mg, chloride 35 mg per mmol; magnesium 1 mmol = 2 mEq = 24 mg. Most requirements are met at 130 mL/kg/day of PN; above that, adjust nutrient concentrations to avoid toxicity. When medications take up much of the volume, concentrate the PN.
Advancing each component
- Dextrose: start at a GIR of 5–7 mg/kg/min (some ELBW infants tolerate only 3.5–4.5 at first). Advance by 1–2 mg/kg/min while glucose is below 130–150 mg/dL, to a goal of 10–11. If glucose stays above 280–300 mg/dL, reduce the GIR to 3.5 before starting insulin. Peripheral lines: dextrose no higher than 12.5%. Do not add carbohydrate on its own to push calories for slow growth.
- Amino acids: a paediatric amino acid solution designed to mimic breastfed plasma profiles; start at 2–3 g/kg/day and reach goal quickly. Add cysteine 30–40 mg per gram of amino acid to improve Ca/P solubility.
- Calcium and phosphorus: start once custom PN is available, keeping a 1:1 mmol ratio. Below 1000 g, limit calcium gluconate to 1–1.2 mmol/kg/day for the first 72 hours, and check ionized calcium and phosphate daily while advancing. An ionized calcium above 1.45 mmol/L should prompt a phosphate check, and the ratio may need to be unbalanced. Peripheral PN: Ca and P no more than 1.2 mmol/100 mL each. Never remove phosphorus for more than 48 hours without also adjusting calcium and following ionized calcium. Sodium phosphate can replace potassium phosphate mmol for mmol.
- Magnesium: leave it in unless serum Mg is above 3.9 mg/dL; resume when it falls below 3 mg/dL.
- Carnitine: 10 mg/kg/day for all infants on PN (human milk contains 3–5 mg/dL); 20 mg/kg/day on ECMO or kidney replacement therapy.
- Trace elements in renal failure: selenium and chromium accumulate — give them less often but keep zinc daily. For intestinal failure or cholestasis, monitor zinc, copper and selenium (chapter 11.8).
| Birth weight (Baylor Table 14-5) | Lipid start | Advance by (if TG <250 mg/dL) | Triglycerides |
|---|
| ≤750 g | 0.1 mL/h for 12 h (lowest pump rate) | 0.5–1 g/kg/day (2.5–5 mL/kg) | At 12 h (or with morning labs), then with every advance |
| 751–1000 g | 1 g/kg/day (5 mL/kg) | 1 g/kg/day | With every advance |
| >1000 g with SGA/IUGR, postnatal steroids or sepsis | 1 g/kg/day | 1 g/kg/day | With every advance |
| >1000 g, AGA | 2 g/kg/day (10 mL/kg) | 1 g/kg/day | Once at goal of 3 g/kg/day |
Essential fatty acids: linoleic acid must supply ≥3% of calories — met by Intralipid at 0.5–1 g/kg/day or SMOFlipid at 3 g/kg/day; EFAD has not been described with Omegaven at 1 g/kg/day. Run lipid continuously at a constant rate to a goal of 3 g/kg/day (Omegaven at 1 g/kg/day). If TG is above 250 mg/dL, cut by 0.5–1 g/kg/day and recheck in 24 h. At 251–400 mg/dL, keep Intralipid at at least 0.5 g/kg/day to prevent EFAD. A level drawn 4–6 h after pausing the infusion can show clearance. Consult the nutrition team if lipid cannot be resumed or advanced beyond 0.5 g/kg/day within 48 h, or if TG stays above 400 mg/dL. Choosing an emulsion and limiting lipids is covered in the next section.
| Volume-restricted PN (Tables 14-7a/b) | Dextrose | GIR | Protein | Ca / P | Mg | Energy (PN + lipid) |
|---|
| ECMO: 70 mL/kg + lipid 3 g/kg (15 mL/kg) | 22% | 10.7 mg/kg/min | 3.5 g/kg | 1.2 mmol/kg each | 0.4 mEq/kg | 96 kcal/kg |
| Therapeutic hypothermia: 40 mL/kg + lipid 1 g/kg (5 mL/kg) | 25% | 6.9 mg/kg/min | 1.8 g/kg | 0.5 mmol/kg each | 0.4 mEq/kg | 51 kcal/kg |
Fluid-restricted infants, slow growth, and when to stop
- Severe cardiopulmonary disease or cooling: give at least 1.8 g/kg/day of protein, aiming for 2.5–3 g/kg/day as soon as feasible. Spend the limited volume on protein rather than on more than 1 g/kg/day of lipid or high Ca/P. During cooling, check phosphorus and magnesium daily.
- Slow growth on PN: first correct non-nutritional causes — metabolic acidosis, hyponatraemia or total-body sodium depletion, work of breathing, cold stress, anaemia, steroids, infection — then confirm intake is on target.
- Stop lipid when feeds exceed 80 mL/kg/day; stop PN when feeds exceed 100 mL/kg/day, except in intestinal failure.
7. Venous Access
Central vs Peripheral
- Concentrated PN (high glucose/calcium/osmolarity) requires a central line (UVC or PICC).
- Peripheral PN must be dilute (lower glucose/osmolarity) to avoid extravasation and tissue injury; inspect cannula sites frequently.
- Apply central-line insertion/maintenance bundles — PN is a major CLABSI risk (see 8.2).
8. PN Management Algorithm
1
Identify who needs PN
VLBW/ELBW or any neonate not reaching adequate enteral feeds soon → start day 1.
2
Start (standardised bag)
Amino acids + lipids + glucose from day 1; set volume within the TFI plan (7.1); appropriate access.
3
Advance to target
Increase amino acids, lipids, and GIR over the first days per policy; watch glucose and triglycerides.
4
Monitor & adjust
Track electrolytes, glucose, triglycerides, LFTs/bilirubin (cholestasis), and growth; adjust additives (Ca/PO₄, phosphate for refeeding).
5
Advance feeds & wean PN
Increase enteral feeds (7.3); reduce PN proportionally; stop when enteral intake is adequate.
6
⚠ Do-not-miss
Line sepsis, PN-associated cholestasis, hypertriglyceridaemia, hyperglycaemia, refeeding electrolyte shifts, and calcium–phosphate precipitation.
8+. Choosing a Lipid Injectable Emulsion (Baylor Ed. 33)
Three emulsions, three jobs: soybean-only for most infants, the multi-component emulsion to prevent liver disease in those at risk, and the fish-oil emulsion to treat it once cholestasis is established.
| Emulsion | When to use it | Oil composition |
|---|
Intralipid
(2 kcal/mL) |
- First line in all infants except those with, or at risk of, IFALD.
- When lipid dosing must be restricted for an extended period, to prevent essential fatty acid deficiency.
- In congenital diaphragmatic hernia and congenital heart disease before repair, and while on ECMO.
| 100% soybean |
SMOFlipid
(2 kcal/mL) |
- Surgical gastrointestinal conditions — gastroschisis, omphalocele, spontaneous intestinal perforation, NEC stage 2 or greater.
- Enteral nutrition below 50 mL/kg/day at 14 days of age with an expected prolonged need for PN.
- In CDH: after repair, and after ECMO.
| 30% soybean · 30% MCT (coconut) · 25% olive · 15% fish |
Omegaven
(1.1 kcal/mL) | Conjugated bilirubin ≥2 mg/dL and age ≥14 days — that is, established IFALD. | 100% fish oil |
Lipid limiting is not the answer
Restricting Intralipid to 1 g/kg/day once conjugated bilirubin reaches 1.5 mg/dL is a strategy that has proved suboptimal at preventing IFALD and is now practised only rarely. Limiting SMOFlipid is strongly discouraged — it causes essential fatty acid deficiency and there are no safety or efficacy data for restricting it (very low certainty evidence, strong recommendation). Where limiting a lipid emulsion genuinely is warranted — hypertriglyceridaemia, fluid restriction, CDH pre-operatively or on ECMO with a high conjugated bilirubin, cholestasis within 14 days of birth — consult the nutrition team for a safe way to do it.
Omegaven in practice
- Exclude infants whose cholestasis is primarily from viral hepatitis or primary liver disease, and those with clinically severe bleeding requiring blood products.
- Stop Intralipid or SMOFlipid and start Omegaven at 1 g/kg/day by continuous infusion over 24 hours — 16–22 hours a day if PN is being cycled before discharge. More than 1 g/kg/day is not encouraged by the FDA under this indication. Central or peripheral line both acceptable.
- Because the lipid supplies only 1 g/kg/day, the glucose infusion rate may need to rise to 14–17 mg/kg/min as tolerated to supply enough calories for growth.
- Expect the conjugated bilirubin to rise over the first week, then decline gradually, with complete resolution over about 7 ± 2 weeks. Cholestasis counts as resolved at CB below 2 mg/dL, typically after 6–10 weeks of therapy.
- Continue until enteral nutrition is tolerated at 80 mL/kg/day or more, even if the cholestasis clears sooner. There is no evidence for continuing after enteral autonomy.
- An infant who had Omegaven before and returns to PN may resume it even with CB below 2 mg/dL — liver function tests can stay abnormal for months after the bilirubin normalizes.
- Monitoring: conjugated bilirubin and triglycerides immediately before starting, triglycerides again within 48 hours, then both weekly until it is stopped; AST, ALT and GGT every other week.
SMOFlipid in practice
- Exclude infants with CDH or congenital heart disease before repair and while on ECMO — they stay on Intralipid.
- Starting at birth: 1 g/kg/day on day 1, 2 g/kg/day on day 2, 3 g/kg/day on day 3. Replacing Intralipid: match the existing dose, usually 3 g/kg/day. Before transitioning, confirm the infant can tolerate 3 g/kg/day to meet minimum essential fatty acid requirements.
- Monitoring: conjugated bilirubin and triglycerides before starting, then weekly; AST, ALT and GGT every other week.
- Honest appraisal: the better biochemical profile has not translated into matching clinical benefit — the effect on preventing and treating cholestasis is modest, long-term neurodevelopmental data are sparse, and use during ECMO or anticoagulation has not been studied. Compatibility data for SMOFlipid and Omegaven with other medications are lacking; Intralipid compatibility data are used in the interim.
Trace elements and recognizing end-stage liver disease
- In infants with significant secretory zinc losses — gastrointestinal disease, an ostomy, surgery — give additional zinc at 400 mcg/kg/day (preterm) or 100–250 mcg/kg/day (term).
- Monitor copper, zinc and selenium every four weeks, or as blood volume allows, in infants with cholestasis on PN.
- Call the liver team early for a preterm infant with hepatomegaly, splenomegaly, a raised liver panel or impaired synthetic function. Worsening conjugated hyperbilirubinaemia, rising PT, glucose instability, growing hepatosplenomegaly, caput medusae, ascites or GI bleeding from portal hypertension point to irreversible liver disease and a possible liver or intestinal transplant assessment.
9. Complications
| Complication | Watch for | Action |
|---|
| Line-related sepsis (CLABSI) | Instability, positive cultures | Line bundles; treat/remove line (see 8.2). |
| PN-associated cholestasis (PNALD/IFALD) | Rising conjugated bilirubin with prolonged PN | Minimise PN duration; advance enteral feeds; composite lipids; specialist input. |
| Hypertriglyceridaemia | High triglycerides on lipid advancement | Reduce lipid rate; recheck. |
| Hyper-/hypoglycaemia | Glucose out of range | Adjust GIR (before insulin); treat hypoglycaemia. |
| Metabolic bone disease | Low phosphate, high ALP | Ensure Ca/PO₄/vitamin D; monitor. |
| Refeeding syndrome | Low PO₄/K/Mg in growth-restricted infants | Provide phosphate; monitor and replace. |
10. Transition to Enteral Feeding
Wean as the Gut Takes Over
- Start trophic feeds early (7.3) even while on PN; advance enteral volumes as tolerated.
- Reduce PN in step with rising enteral feeds to keep total intake on target; stop PN once enteral nutrition is adequate.
- Prioritising enteral (especially human-milk) feeding shortens PN duration and reduces cholestasis and line infection.
11. Monitoring
| Parameter | Frequency | Why |
|---|
| Glucose | Frequent on changes, then per stability | Hyper/hypoglycaemia; titrate GIR. |
| Electrolytes (incl. Ca, PO₄, Mg) | Regular | Balance; refeeding; bone health. |
| Triglycerides | With lipid advancement | Detect hypertriglyceridaemia. |
| LFTs / conjugated bilirubin | Periodic on prolonged PN | PN-associated cholestasis. |
| Growth (weight/length/head) | Regular on preterm charts | Nutritional adequacy. |
| Line site / signs of sepsis | Continuous | CLABSI prevention. |
Baylor Ed. 33 laboratory schedule on PN (Table 14-14)
| Test | When |
|---|
| Conjugated bilirubin | All infants in the first 24 hours; then weekly on PN after 14 days of PN |
| Ionized calcium and glucose (at-risk NICU admissions: IDM, SGA, IUGR, preterm) | At 24 hours of age |
| Glucose on any IV dextrose | Daily or more often until stable; every 6–12 h in ELBW, stressed or septic infants; up to hourly on insulin |
| Ionized calcium | Every 24 h for the first 3 days and while Ca/P are advanced, until stable; above 1.45 mmol/L → check phosphorus |
| Triglycerides | ≤750 g: 12 h after starting lipid and with every advance; ≥751 g: with every advance (thresholds in section 6+) |
| Electrolytes, BUN, creatinine, glucose, TG | Weekly or as indicated |
| ALT, AST, GGT, alkaline phosphatase, Ca, P, haematocrit | Every 2 weeks (after 14 days of PN) or as indicated; exclusive PN over 4 weeks follows the intestinal failure schedule (chapter 11.2) |
First-week labs for ≤28 weeks or ≤1000 g (Table 14-15)
| When | ≤24 6/7 weeks or ≤750 g | 25–28 weeks or 751–1000 g |
|---|
| Delivery room / admission | Glucose, then hourly for at least 2 h or until stable; recheck 30 min after any bolus | Glucose, then 1 h after fluids start |
| Every 12 h for the first 48 h | Electrolytes and glucose; TG 12 h after lipid starts | — |
| Every 24 h for the first 3 days | Chem-10 (Na, K, Cl, CO₂, BUN, Cr, glucose, P, Ca, Mg), TG, ionized Ca | Chem-10, TG, ionized Ca |
| At 24 h | Bilirubin panel | Bilirubin panel |
| Each lipid advance | TG | TG |
12. Contraindications & Precautions
Safety Cautions
- Do not delay PN (start day 1) — but do not run concentrated PN peripherally (extravasation injury).
- Advance lipids/glucose within limits — watch triglycerides and glucose; adjust GIR before insulin.
- Respect calcium–phosphate compatibility (pharmacy-checked) to avoid precipitation.
- Minimise PN duration and prioritise enteral feeds to reduce cholestasis and line sepsis.
- Consider refeeding risk (phosphate/potassium/magnesium) in growth-restricted infants.
- Apply strict aseptic line care (major CLABSI source).
13. Escalation & Family Support
Escalate When…
- Suspected line sepsis, worsening cholestasis, refractory hyperglycaemia/hypertriglyceridaemia, or faltering growth — senior/NICU, pharmacy, and dietetic/nutrition team.
- Prolonged PN dependence or intestinal failure — specialist gastroenterology/nutrition support.
Parent Counselling Points
- "Because your baby's gut isn't ready for full milk feeds yet, we give balanced nutrition through a drip so growth can continue from day one."
- "As your baby tolerates more milk, we reduce the drip and aim to stop it — your expressed milk helps us get there sooner and protects the gut and liver."
14. Key Pearls
High-Value Clinical Pearls
- Start PN day 1 with amino acids AND lipids (not glucose alone) — early protein prevents deficit.
- Use standardised starter bags for immediate, safe day-1 nutrition.
- Concentrated PN needs a central line; peripheral PN must be dilute.
- Adjust GIR before reaching for insulin in hyperglycaemia; monitor triglycerides on lipids.
- Minimise PN duration — advance enteral (human-milk) feeds to reduce cholestasis and line sepsis.
- Ensure Ca/PO₄/vitamin D for bone health; consider refeeding risk in growth-restricted infants.
15. Common Mistakes to Avoid
| Mistake | Why it harms | Better practice |
|---|
| Glucose-only "PN" on day 1. | Negative nitrogen balance. | Amino acids + lipids from the start. |
| Delaying PN awaiting individualised bags. | Nutrient deficit. | Use standardised starter bags. |
| Concentrated PN peripherally. | Extravasation injury. | Central line for concentrated PN. |
| Reflex insulin for hyperglycaemia. | Hypoglycaemia risk. | Adjust GIR first. |
| Prolonged PN when gut is ready. | Cholestasis, sepsis. | Advance feeds; wean PN. |
| Forgetting Ca/PO₄/refeeding. | Bone disease/refeeding shifts. | Provide minerals; monitor phosphate. |
16. Board-Style High-Yield Summary
Key Takeaways
- Start PN day 1 in VLBW/ELBW with early amino acids and lipids; standardised bags enable this.
- Typical targets (verify): amino acids to ~3.5–4, lipids to ~3–4 g/kg/day, GIR ~8–12 mg/kg/min, ~90–120 kcal/kg/day.
- Concentrated PN via central line; dilute for peripheral; strict aseptic line care.
- Monitor glucose, triglycerides, electrolytes/Ca/PO₄, LFTs/conjugated bilirubin, and growth.
