Psychomotor and intellectual development after deep hypothermia and circulatory arrest in early infancy.


Somatic, psychomotor, and intellectual development were studied in 11 patients who had total correction of congenital cardiac malformation in early infancy by the method of surface-induced deep hypothermia and circulatory arrest up to 43 minutes. Time between operation and re-evaluation ranged from 3 to 11 years (average 7 years). Somatic development was normal in all children. Psychomotor and intellectual behavior, measured by a battery of specially adapted test methods, failed to show a statistically significant difference when compared between the study group, a matched control group, and the normal population. Normal scores in psychomotor tests and normal intelligence quotients (I.Q.) were present in 8 patients; mental retardation was found in 2 patients: and unstable behavior, evident from different tests, was present in one. Except for the last case, in none of the patients was the method was found to be the primary cause of the abnormal behavior. Deep hypothermia and circulatory arrest in early infancy does not appear to have a negative influence on somatic, psychomotor, or intellectual development.
