1. Background
Preterm infants are born with an immature gut and are consequently unable to digest sufficient milk to meet their nutritional requirements for at least 10-14 days post birth. They also have limited nutrient stores, so are therefore at a high risk of accumulating significant nutrient deficits and consequential poor growth which is associated with poor neurodevelopmental outcome in later life.1
Parenteral Nutrition (PN) is an important aspect of neonatal care by which the infant’s specific nutritional requirements can be met intravenously. Evidence confirms that providing optimal nutrition early can minimise growth failure and associated neuro-cognitive effects1. PN is also essential for infants who may not tolerate enteral feeds such as those with congenital or acquired gut disorders. Standardised bags maximise nutrient delivery in line with BAPM recommendations2 and
minimise the risk of errors in prescribing and compounding. Using 48 hour bags reduces the
number of times lines are accessed and thus reduces line infection rates. Standardised PN
should always be used when administering PN3, apart from in exceptional cases.
The aim of this guideline is to provide clear, evidence based guidance and procedures for using PN on the neonatal unit. This is to ensure safe and optimum management of parenterally fed infants and minimise the risks associated with this form of nutrition support.
2. Scope
This guidelines applies to neonatal units that care for and manage patients on Parenteral Nutrition within the South west Neonatal Network, this includes the following hospitals.
Royal United Hospital Bath NHS Trust - Royal United Hospital Bath North Bristol NHS Trust - Southmead Hospital, Bristol University Hospitals Bristol NHS Foundation Trust - St Michaels Hospital, Bristol Royal Devon and Exeter NHS Foundation Trust - Royal Devon and Exeter Hospital Gloucestershire Hospitals NHS Foundation Trust - Gloucester Royal Hospital Plymouth Hospitals NHS Trust - Derriford Hospital, Plymouth Great Western Hospitals NHS Foundation Trust - Great Western Hospital, Swindon Taunton and Somerset NHS Foundation Trust - Musgrove Park Hospital, Taunton Royal Cornwall Hospitals NHS Trust - Royal Cornwall Hospital, Truro
3. Indications for use2 PN should be considered in the following infants:
All infants admitted to NICU < 1.25kg or < 30/40 weeks gestation
Infants > 30/40 weeks gestation or > 1.25kg who are not anticipated to be on > 100ml/kg/day enteral feeds within 5 days

Infants with intestinal disease precluding feeding e.g. necrotising enterocolitis (NEC), gastroschisis, intestinal atresia
If indicated from birth, PN should be started within the first 24 hours of life, ideally within 6 hours of
birth or from confirmation of line placement.
4. PN availability There are 3 types of PN bags available across the region:
SW Neonatal PN Bag 1 (minimal electrolytes)
SW Neonatal PN Bag 2 (preterm maintenance)
SW Neonatal PN Bag 3 (term maintenance) N.B. bag size and availability will vary between units
5. Administration PN should be removed from the fridge at least one hour prior to use. Aqueous PN bags should not run for longer than 48 hours and should be infused via a 0.2 micron filter. Lipid syringes should not run for longer than 24 hours and should be infused over 24 hours. The PN giving set and filters must be changed every 48 and 24 hours respectively for aqueous and lipid solutions.
Restarting PN after full enteral feeds or if not starting PN at time of birth: Start on day 3 of the appropriate PN flowchart
Is the Infant < 1.25kg or
< 30/40 weeks gestation?
Start PN within 6 hours of birth
(See ‘Preterm PN’ flowchart)
Will the infant achieve
>100ml/kg/day enteral
nutrition by day 5 of life
Start enteral nutrition
according to local protocol
Start PN as soon as possible
after birth

Lines
PN should ideally be administered via a central venous catheter (for example, UVC or long line); peripheral venous catheters should be avoided for routine administration of PN where possible due to risk of extravasation injuries. This should be a short-term measure until central access is secured or PN is stopped.
If PN is to be administered via a peripheral venous cannula then lipid MUST also be administered
along the same line as the aqueous PN.
Ideally a line should be used solely for PN although this is not always possible in neonates due to difficulties in venous access. No medication should be given down the same line as the PN without checking compatibility. If in any doubt then assume that they are not compatible and contact pharmacy. Bolus medication may be given with a flush of sodium chloride 0.9% before and afterwards. Access to the line should be minimised to reduce risk of infection.

7. Monitoring Routine biochemical monitoring should take place in all infants on PN as it is crucial to prevent and
treat instabilities potentially caused by PN.
Any derangement from normal range should be discussed with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available, before prescribing. Below is a suggested schedule of monitoring however requirements may differ for individual infants and situations3.

*Special Considerations Blood Glucose
Measure blood glucose levels (BGL) 6-12 hourly whilst increasing PN and 12-24 hourly when on full PN and stable
Follow the unit guidelines for the management of hyperglycaemia. A BGL >11mmol/l is currently the classification of hyperglycaemia in a neonate.
Triglyceride monitoring
For infants <26/40 CGA, or those that are severely septic, then triglycerides should be monitored once they are receiving 10ml/kg/day lipid (1.5g/kg/day), and then again at 20ml/kg/day (3g/kg/day). From then on it should be routinely on a Sunday.
All other infants should have triglycerides measured weekly on a Sunday. More frequent monitoring may be required in certain circumstances, for example if an infant has
had previously high triglyceride levels, is septic, catabolic or critically ill, or has severe and unexplained thrombocytopenia.
Urinary Electrolytes Sodium is thought to be critical to growth and measuring urinary sodium can be a useful
indicator of whole body sodium status. Checking this regularly, particularly in surgical infants who are at higher risk of sodium
depletion, is important. There is no nationally agreed reference range but the surgical team at BRHC advise
supplementing sodium if the urinary sodium level is below 20mmol/L. There should be a urinary sodium to potassium ratio of approximately 2:1.
If an infant requires supplementation, urinary sodium should be checked weekly until it is above 20mmol/L.
Long term PN and Trace elements Infants receiving PN long term i.e. >3 weeks and have minimal or no enteral feeds should also
have the following monitored on a monthly basis. o Trace element status to include copper, manganese, selenium and zinc o Fat soluble vitamin status
Trace elements should also be monitored in infants with pre-existing imbalances or who have a reduced excretion of bile e.g. in cholestasis, renal failure or hepatic disease. This should happen irrespective of length of time on PN.
8. Managing Metabolic Complications See Appendix One for information regarding managing metabolic complications.
9. Weaning TPN 1. As enteral feeds increase, wean all glucose infusions (5% and 10%) to zero. 2. Once enteral feeds at 30ml/kg/day, wean lipid infusion down to 15ml/kg/day and then titrate
aqueous phase to total fluid allowance. 3. As enteral feeds increase to 60ml/kg/day, wean lipid infusion down to 10ml/kg/day and then
titrate aqueous phase to total fluid allowance.

4. As enteral feeds increase to 90ml/kg/day, wean lipid infusion down to zero (unless running peripherally, in which case keep lipid at 10ml/kg/day) and then titrate aqueous phase to total fluid allowance.
5. PN can be stopped once tolerating 120ml/kg/day enteral feeds, or continued at 30ml/kg/day and weaned until tolerating 150ml/kg/day enteral feeds.
When Enteral feeds reach Wean Lipid infusion to Titrate Aqueous phase to
30ml/kg/day 15ml/kg/day total fluid allowance
As Enteral feeds increase to Wean Lipid infusion to Titrate Aqueous phase to
60ml/kg/day 10ml/kg/day total fluid allowance
90ml/kg/day Zero* (unless peripheral) total fluid allowance
120ml/kg/day Zero* (unless peripheral) total fluid allowance
*Unless running peripherally, in which case keep at 10ml/kg/day
NOTE – some high risk infants may continue on a small amount of aqueous PN and lipid to support
growth

Appendix One
The management of metabolic complications
Hyperglycaemia If blood glucose level (BGL) >11mmol/L, which has been confirmed with a capillary/venous sample (1
sample has to be peripheral in case of contamination from central fluids), then treat for
hyperglycaemia.
1) Ensure all additional glucose infusions are reduced to 5% glucose, including the diluent for drug infusions, if compatible
2) If still hyperglycaemic, decrease aqueous PN rate by 30ml/kg/day and supplement volume with 5% glucose
3) If still hyperglycaemic, consider insulin (see insulin guideline) (Ensure minimum glucose infusion rate is no less than 6mg/kg/min)
Hypoglycaemia 1) Increase the concentration of all additional glucose infusions in a step wise manner from 10% to
15% to 20%. Ensure all drug infusions are in 10% glucose if compatible. 2) If still hypoglycaemic, decrease aqueous PN by 30ml/kg/day and supplement with 20% glucose 3) If still hypoglycaemic, stop PN and replace fluid volume with glucose 20% with electrolytes,
where required
Hypernatremia 1) Assess fluid balance, weight and hydration status. 2) Ensure arterial line is kept patent with heparinised 0.45% sodium chloride (not 0.9%), where
available 3) For immediate action, consider changing aqueous PN to SW Neonatal PN Bag 1. If true sodium
over supplementation discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available
Hyponatraemia 1) Assess fluid balance, weight and hydration status.
Water overload must be considered before supplementation of sodium is prescribed. In these cases fluid restriction is usually required and can be achieved by reducing the supplementary glucose 10% infusion rate.
2) If it is felt there is a true sodium deficit and this is not being corrected by the current PN regimen (ensure aqueous PN is not sodium free) then sodium losses should be calculated and replaced by using the standard sodium concentrations in the table below, to supplement sodium.
3) Ensure arterial line is kept patent with heparinised 0.9% sodium chloride (not 0.45%), where available
There are 5 standard sodium concentrations made up in glucose 10%. For central use only These supplementary sodium infusions allow replacement of sodium in addition to the sodium prescribed in the PN.

Hyperkalaemia 1) Ensure that the hyperkalaemia result is true, i.e. not haemolysed. 2) Stop any additional potassium infusions 3) For immediate action, consider changing aqueous PN to SW Neonatal PN Bag 1. If true potassium
over supplementation discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available
Hypokalaemia (<3mmol/L) 1) Ensure aqueous PN bag contains potassium 2) Replace deficit by using supplementary potassium infusion. Aim to correct over 24 hours.
For central use only 3) Magnesium levels should also be checked and corrected if required
Add 10mmol Potassium Chloride (5ml of 15% Potassium Chloride) to 45ml glucose 10% to make
up 50ml infusion containing 0.2mmol/ml of Potassium Chloride.
Infusion rate 0.1mmol/kg/hr (0.5ml/kg/hr) gives potassium supplementation of 2.4mmol/kg/day
Occasionally, larger potassium requirements are needed (eg stoma losses, diuretics). These should be met by using the standard solution above and increasing the RATE of infusion as described below.
Infusion rate 0.2mmol/kg/hr (1ml/kg/hr) gives potassium supplementation of 4.8mmol/kg/day
Infusion rate 0.3mmol/kg/hr (1.5ml/kg/hr) gives potassium supplementation of 7.2mmol/kg/day
NB: glucose 5% can be used as the diluent in cases of hyperglycaemia
Hypercalcaemia (corrected calcium >3mmol/l) 1) Check serum phosphate levels. Hypercalcaemia may be secondary to hypophosphataemia
particularly if the latter is severe or persistent. The treatment in these cases is to supplement phosphate.
2) If the phosphate level is within range then any infusion containing calcium may need to be stopped, including PN. NB: all SW Neonatal PN bags contain calcium
3) Discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available
Hypocalcaemia (corrected calcium <1.5mmol/l, or ionised calcium <1mmol/L) 1) Check acid-base balance as metabolic alkalosis decreases ionised calcium levels. 2) Magnesium levels should also be checked and corrected if required 3) Change to SW Neonatal PN Bag 2 (if not already prescribed, and suitable for the patient), as it
contains more calcium than the SW Neonatal PN Bags 1 and 3, and optimise rates if possible. 4) If serum calcium level is still low, then administer 2ml/kg calcium gluconate 10% (0.46mmol/kg)
intravenously over 10minutes. Do NOT administer down the same intravenous line as the PN. 5) If higher amounts of calcium are required, then discuss with Consultant, Neonatal Pharmacist and
Neonatal Dietitian, where available.
Hyperphosphataemia 1) Calcium levels should also be checked and corrected if required 2) If true hyperphosphataemia and immediate action is required then stop aqueous PN and change
to SW Neonatal PN Bag 1. 3) Discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available. Hypophosphataemia (<1.5mmol/L)

1) Potassium levels should be checked and corrected if required 2) Check acid-base balance as metabolic acidosis increases urinary excretion of phosphate 3) Change to SW Neonatal PN Bag 2 (if not already prescribed and suitable for the patient), as it
contains more phosphate than the SW Neonatal PN Bags 1 and 3, and optimise rates if possible. 4) Discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available. 5) If infant tolerating more than half enteral feeds then consider enteral phosphate
supplementation. Hypermagnesaemia 1) If immediate action is required then stop aqueous PN and change to SW Neonatal PN Bag 1.
2) Discuss with Consultant, Neonatal Pharmacist and Neonatal Dietitian, where available.
Hypomagnesaemia 1) Ensure potassium and calcium serum levels are within the normal range
2) Change to SW Neonatal PN Bag 2 or 3 (if not already prescribed, and suitable for the patient), as it contains more magnesium than SW Neonatal PN Bag 1, and optimise rates if possible.
3) Consider magnesium supplementation with 0.4mmol/kg magnesium sulphate intravenously over
10minutes.
Hyperlipidaemia (>2.8mmol/L) For infants <26/40 CGA, or those that are severely septic, then triglycerides should be monitored once they are receiving 10ml/kg/day lipid (1.5g/kg/day), and then again at 20ml/kg/day (3g/kg/day). From then on it should be routinely on a Sunday. All other infants should have triglycerides measured weekly on a Sunday.
More frequent monitoring may be required in certain circumstances, for example if an infant has had previously high triglyceride levels, is septic, catabolic or critically ill, or has severe and unexplained thrombocytopenia. If infant is severely septic consider stopping the lipid infusion and discuss with Consultant, Neonatal
Pharmacist and Neonatal Dietitian, where available.
Triglyceride level
(mmol/L)
Action required When to re-measure
triglyceride
< 2.8mmol/L None Weekly on a Sunday
2.9-3.5mmol/L Reduce lipid infusion by 5ml/kg/day In 3 days
3.64mmol/L Reduce lipid infusion by 10ml/kg/day In 2 days
>4mmol/L Reduce lipid infusion to 5ml/kg/day or
consider stopping
In 2 days
Once repeat triglyceride measurement is <2.8mmol/L increase lipid infusion rate by 5ml/kg/day and repeat measurement every 2 days until target lipid infusion rate is reached. If the level >2.8mmol/L on a repeated test then repeat according to the table above then reduce the rate.
