A 2-year-old boy died from morphine toxicity approximately 35 hours after suspected ingestion of up to 7 Kapanol (slow-release morphine) capsules accessed from his father's medication left unguarded in the home. Hospital care was appropriate, with nurses performing regular observations and showing good clinical vigilance. However, there was a critical transition point: detailed neurological observations (which had been half-hourly) ceased abruptly when the day shift commenced, before medical review occurred. Early signs of morphine toxicity (pupil constriction, respiratory depression) were identified overnight and managed conservatively pending possible deterioration. The child appeared clinically well on the morning of day 2, leading to discharge of siblings and continued routine management. Death occurred unexpectedly that night. The coroner found no criticism of clinical care, but highlighted that standard pharmacokinetic assumptions about morphine peak effects (3-12 hours) did not apply in this case, warranting caution in very young children with opioid ingestion.

Coroner's recommendations
The Minister for Health should consider the introduction of appropriate standards in South Australia for child-proofing of blister packaging for hazardous pharmaceuticals, with reference to existing standards in other countries and evidence that two-year-old children can access medications in current blister packs.
The Child Death and Serious Injury Review Committee should conduct a review pursuant to section 52S(3)(e) of the Children's Protection Act 1993 into the death of Ian Myles Smith, including consideration of the Department for Families and Communities' role.
