  • Retrospective cohort study
  • single-centre

Authors' conclusion

Greater postnatal exposure to opioids was associated with worse neurodevelopmental outcomes across cognitive, language, and motor domains, independent of other less modifiable factors.

Study context

Population
Infants undergoing congenital heart surgery32% STS-EACTS category 4 or 5
Participants
526 infants
Exposure
Cumulative opioid exposure over the first year of life
Outcome
Bayley-III/IV cognitive, language and motor scores
Follow-up
2 years

Main finding

As reported in the abstract

Bayley-III/IV scores per log-transformed morphine mg equivalents (adjusted)

Cognitive: β per log-transformed morphine mg equivalents

−1.0, P = 0.04

Language: β

−1.2, P = 0.04

Motor: β

−1.1, P = 0.02

Observational data: associations, not effects.

Further findings

Unadjusted analyses

Higher opioid exposure associated with worse scores in all 3 Bayley-III/IV domains
all P < 0.05

Other factors associated with Bayley-III/IV scores

Total hospital length of stay, prematurity, genetic syndromes and worse neighborhood socioeconomic status associated with worse scores across all domains
all P < 0.05
