IV BOLUS/LOADING DOSE
Neonates < 1 kg
Using 100 microgram/2 mL injection draw up 1 mL (50 microgram fentanyl)) and add 24 mL sodium chloride 0.9% to make a final volume of 25 mL with a concentration of 2 microgram/mL.
Neonates ≥ 1 kg
Using 100 microgram/2 mL injection draw up 1 mL (50 microgram fentanyl)) and add 9 mL sodium chloride 0.9% to make a final volume of 10 mL with a concentration of 5 microgram/mL.
PRE-MEDICATION FOR INTUBATION
As above for IV bolus.
|
Administration
|
IV slow push over 3−5 minutes
IV infusion via syringe pump
|
Monitoring
|
Care should be taken in using fentanyl in neonates with hepatic or renal dysfunction.
Full cardiorespiratory monitoring is required.
Monitor for urinary retention.
|
Contraindications
|
Known hypersensitivity to fentanyl.
|
Precautions
|
Tolerance can occur with use >5−7 days.
Withdrawal has been reported in patients who have received continuous infusions for >5days.
Chest wall rigidity can occur at higher doses.
May cause respiratory depression.
May cause urinary retention.
May decrease intestinal motility.
|
Drug Interactions
|
Ketoconazole and erythromycin are potent inhibitors of fentanyl metabolism.
When given in combination with amiodarone can cause profound bradycardia, sinus arrest and hypotension.
|
Adverse Reactions
|
Nausea and/or vomiting
Muscle/chest wall rigidity (usually naloxone responsive). Naloxone 0.01−0.04 mg/kg reversed muscle rigidity immediately allowing resuscitation in a case series of 8 patients.
At high doses can cause neuro-excitation and rarely seizure like activity/myoclonic movements.
Respiratory depression.
Bradycardia (usually atropine responsive).
Urinary retention.

Special Comments
|
In comparison to morphine, fentanyl has a quicker onset of action (3 minutes), shorter duration (90 minutes) of action and less haemodynamic instability. Fentanyl is 50–100 times more potent than morphine.
It blocks endocrine stress responses.
It causes less histamine release than morphine.
It decreases pain-induced increases in pulmonary vascular resistance.

Evidence summary
|
Efficacy
Opioids are to be used selectively based on clinical judgment and evaluation of pain indicators, although there are limitations to pain measurement in newborns1 (LOE 1 GOR B).
A short course of low dose fentanyl by infusion reduces behavioural sedation scores, O2 desaturations and neuroendocrine stress responses in preterm ventilated infants2 (LOE II, GOR B).
Continuous infusion of fentanyl in the post-operative period achieves acceptable pain control but there may be increased need for ventilator support￼ (LOE II, GOR C). (LOE II, GOR C).
In very preterm infants on mechanical ventilation, continuous fentanyl infusion plus boluses of fentanyl reduces acute pain and increases side effects but does not reduce prolonged pain compared with boluses of fentanyl alone￼ (LOE II GOR B). (LOE II GOR B).
Safety
Respiratory depression occurs when anaesthetic doses (greater than 5 microg/kg/min) are used and may also occur unexpectedly because of redistribution. Chest wall rigidity has occurred in 4% of neonates who received doses of 2.2 to 6.5 microg/kg, occasionally associated with laryngospasm5 (LOE IV GOR D). This was reversible with administration of naloxone.
When controlling for other variables, the cumulative fentanyl dose did not correlate with neurodevelopmental outcomes in very low birth weight infants￼ (LOE III GOR C). (LOE III GOR C).
Tolerance may develop to analgesic doses7.
Significant withdrawal symptoms have been reported in patients treated with continuous infusion for 5 days and longer (LOE IV GOR D).
Pharmacokinetics
Fentanyl is metabolised in the liver (CYP3A4) and excreted in the urine. There is wide variability in apparent volume of distribution and serum half-life can be up to 15 hours. There is significant correlation between postnatal age and total body clearance8.
