title: Obstetrical medication and the human newborn: the influence of alphaprodine hydrochloride on visual behaviour.
abstract: The visual habituation of two groups of newborn infants was tested at a mean age of 2.9 days with large achromatic squares of varying luminance. Mothers of the infants in one group received no medication during labour; mothers in the second group received a single dose of the synthetic narcotic alphaprodine hydrochloride. The two groups did not differ in the number of trials to reach the criterion, but newborns in the no-medication group fixated the stimuli for much longer periods than did infants in the alphaprodine group. First-fixation times of babies in the alphaprodine group were shorter when drug-to-delivery intervals were longer. These results, although tentative, imply that babies of medicated and unmedicated mothers differ in the manner in which they respond to visual stimuli.
