The prognosis of near-drowned children.

Thirty children were treated for near-drowning in the Children's Hospital, University of Helsinki during 1971--1976. The patients were divided into 3 groups according to the prognosis: group I included 13 children (43%) with a favourable prognosis, group II four children (13%) with a less favourable prognosis who developed severe sequelae, and group III 13 children with poor prognosis and in whom the subsequent outcome proved fatal. The surviving children underwent neurological, neurophysiological and psychological examination 6--58 months after the accident. The children in group I had slight neurological or psychological signs, some children presented a lowered intellectual functioning level. The children in group II were tetraplegic, unable to speak and had convulsions. The following factors were important in affecting prognosis: the longer the immersion time, the worse the prognosis. However, prognosis could still be favourable with an immersion-time of 11-20 min. Prognosis was bad if the first pH value was less than 7.00. The arterial oxygen pressure values measured during the treatment did not correlate with the prognosis but a low rectal temperature on admission was usually associated with a bad prognosis. The degree of EEG-disturbance had a prognostic value. However, the follow-up recording correlated better with the prognosis than the recordings during the first 24 hours, after which worsening of the EEG sometimes showed a progressive brain lesion.
