Abstract
AIM: This study aimed to identify the clinical features of infants who were healthy at birth, but developed sudden unexpected collapse and were then diagnosed with cerebral palsy before 5 years of age. METHODS: We retrospectively analysed 1182 records from the no-fault Japan Obstetric Compensation System for Cerebral Palsy database up to 2016. This identified 45 subjects (3.8%) who were subsequently diagnosed with severe cerebral palsy due to sudden unexpected postnatal collapse (SUPC). They were all healthy at birth, based on the criteria of five-minute Apgar scores of seven or more, with normal umbilical cord blood gases and no need for neonatal resuscitation within five minutes of birth. RESULTS: The median birth weight of the 45 subjects (26 males) was 2770 g (range 2006-3695 g). Of these, 10 developed SUPC during early skin-to-skin contact (SSC). Medical personnel were not present in all 10 cases: nine were being breastfed at the time and eight of the mothers did not notice their infant's abnormal condition until medical staff alerted them. CONCLUSION: This national study of children with cerebral palsy who appeared healthy at birth found that unsupervised breastfeeding was a common factor in cases of SUPC during early SSC.
