Critically ill fullterm neonates with severe respiratoryfailure \Jlo had only a 20% chance of survival are beingtreated with IDD, a new technique that provides tanporarylife support by IlffiIlS of a nndified heart-lung machine,Cannulas are surgically inserted into the jugular vein andthe right comon carotid artery in order to externallyoxygenate the infant's blood, Sioce June 1985, ::6 infantshave been treated at our hospital. 28 (7&) of whan havesurvived. Orr report concerns the neurcdeveloprentalfunctioning of these survivors during ear'ly infancy. Orrpreliminary findings indicate that in spite of the severityof their initial illness and the invasive aspect of the IDDprocedure (permanent ligation of the right camon carotidartery), for rmst of the infants early neurodeve1oprentalsequelae appear to be minor. Prognosis is poor for ~infants, however performmCe on a visual attention task wasnorrml for 68'1: of the IDD infants at the tfrre of discharge,and perfonrarce was nonral, for 8& on subsequent testingwith the Bayley Scales, The positive correlation betweenvisual attention and perfomance on the Bowley for this riskgroup raises the possibility of rmre subtle problems. Theresults of the early neurodeveloprental. assessrents of thisunique populatfon are encouraging, ~ver these infants arestill at risk for developrental problems in childhood.Detafls of neurobehavioral functioning will be updated andpresented.
