Neonatal abstinence syndrome (NAS)
• Syndrome of drug withdrawal with non-specific signs in a baby following exposure to a variety of substances inutero
Queensland Clinical Guideline: Perinatal substance use: neonatal 3
Neonatal withdrawal may be caused by inutero exposure to:
• Opioids • Benzodiazepines, • Selective Serotonin Reuptake Inhibitors
(SSRIs) • Alcohol and tobacco • Amphetamines
Queensland Clinical Guideline: Perinatal substance use: neonatal 4
Resuscitation
• Usual neonatal resuscitation as required • Do not administer Naloxone
◦ In the neonatal period if baby has had inutero exposure to opioids
◦ May precipitate severe rapid onset of seizures
Queensland Clinical Guideline: Perinatal substance use: neonatal 5
Symptomatic baby
• Clinical assessment and examination • Review maternal history of licit/illicit
substances • Discuss substance use with woman
◦ May be undisclosed • Consider admission to
special care nursery
Queensland Clinical Guideline: Perinatal substance use: neonatal 6
Symptomatic baby
• Supportive care • Postnatal observations • Finnegan scores
◦ Score the average of baby’s behaviour since last scored
Queensland Clinical Guideline: Perinatal substance use: neonatal 7
Clinical signs
• Suspect NAS if baby: ◦ Unsettled ◦ Irritable ◦ Has high pitched cry ◦ Jittery or has tremors ◦ Does not feed well +/- diarrhoea
• Signs may be caused by concurrent illness
Queensland Clinical Guideline: Perinatal substance use: neonatal 8
Onset of withdrawal
• Heroin: between 24 and 72 hours of age (may be earlier)
• Methadone/Buprenorphine: between 72 hours to 7 days
• SSRI: Day 2 up to day 5–7
Queensland Clinical Guideline: Perinatal substance use: neonatal 9
Differential diagnosis
• Infection • Hypoglycaemia • Hypocalcaemia • Metabolic disorders
Queensland Clinical Guideline: Perinatal substance use: neonatal 10
Clinical examination
• Conduct a full examination • Consider concurrent illness • Review risk factors for neonatal sepsis • Investigate to exclude infection or
metabolic disturbance • Treat any identified illness
Queensland Clinical Guideline: Perinatal substance use: neonatal 11
Preterm babies
• Less severe NAS related to: ◦ Developmental immaturity of specific opiate
receptors/neurotransmitter function ◦ Reduced exposure time ◦ Reduced fatty deposits of drugs
Queensland Clinical Guideline: Perinatal substance use: neonatal 12
Inter-hospital transfer
• If appropriate, transfer the antenatal woman to a higher level facility or
• If required, transfer woman and baby after birth to higher level facility
Queensland Clinical Guideline: Perinatal substance use: neonatal 13
Management of substance withdrawal
• Use non-pharmacological management as first line treatment
• Use pharmacological treatment if withdrawal not adequately controlled
Queensland Clinical Guideline: Perinatal substance use: neonatal 14
Supportive/non-pharmacological care
• Support rooming-in • Minimise hunger─encourage breastfeeding • Early response to baby cues • Decrease environmental stimuli (e.g. light
and sound) • Cluster care─avoid over-stimulation
Queensland Clinical Guideline: Perinatal substance use: neonatal 15
• Individual risk-benefit analysis • Breastfeeding not recommended if:
◦ HIV positive ◦ Using, alcohol, amphetamines, heroin, cocaine
• Encourage/support breastfeeding where possible
• Develop feeding safety plan with woman
Feeding
Queensland Clinical Guideline: Perinatal substance use: neonatal 16
Breast milk
• Analgesic for baby • Soothes agitated baby • Helps meet higher caloric requirements • Helps reduce stress response and
increased vagal tone in woman
Queensland Clinical Guideline: Perinatal substance use: neonatal 17
Formula feeding
• May be primary source of nutrition • Usual education re:
◦ Preparation, ◦ Storage, ◦ Equipment cleaning ◦ Transport
Queensland Clinical Guideline: Perinatal substance use: neonatal 18
Finnegan tool
• Most widely used assessment of opioid withdrawal in term babies
• May be used to aid assessment of other substance withdrawal
• Requires staff training and auditing to ensure reliability and scoring consistency
• Ensure inter- and intra- observer validation of scoring
Queensland Clinical Guideline: Perinatal substance use: neonatal 19
Finnegan scoring
• Start within 2 hours of birth • Score 4–6 hourly 30–60 minutes after feeds • Assign only one score for each sign in each
of the three sections • Score reflects behaviour since previous
assessment • Do not disturb baby to assess signs • Make allowances if baby preterm

Morphine
• Opiate of choice • Less likely to have seizures • Less likely to require treatment with
second line agent • Duration of treatment may be less
Queensland Clinical Guideline: Perinatal substance use: neonatal 23
Phenobarbitone
• Use as an adjunct to Morphine when NAS not controlled
• Initial treatment where substance/s used by woman: ◦ Unknown or polysubstance ◦ Alcohol (intoxication at birth) ◦ SSRI or sedatives (Benzodiazepines)
Queensland Clinical Guideline: Perinatal substance use: neonatal 24
Paediatric review
• Early and daily consultation • When showing signs of NAS • If commencing Morphine or Phenobarbitone • When receiving maximum dose of
medication • Exclusion of other causes
not possible

Discharge planning
• Assess for safe discharge of baby • Minimum 5 days in hospital for opioid
withdrawing baby • Minimum 3 days in hospital for SSRI
exposed baby
