Neurological sequelae in children surviving mechanical ventilation in the neonatal period.

The incidence of mental defect, visual and hearing disability, major neurological handicap, and such minor neurological handicap as can be detected on examination at 2--9 years without formal intelligence testing, is presented among survivors of neonatal mechanical ventilation at Hammersmith Hospital between the years 1966--1973 inclusive. 77(21%) of 367 children survived, over three-quarters of them being born elsewhere. 3 died before the age of 6 months, 2 suddenly and unexpectedly at home, the third accidentally. 1 child was lost to follow up. 11 (15%) of the remaining 73 children had neurological sequelae as defined. In two-thirds this was moderate to severe. Spastic diplegia may no longer be the commonest form of cerebral palsy among those of low birthweight, particularly those surviving severe neonatal illness.
