IN PREVIOUS communications1 we reported that (1) the p H of nasal secretion in situ in clinically normal nasal passages of infants and children was found to range within the levels of 5.0 to 6.7, indicating a slightly acid state of secretion, and that (2) during the act of crying and hyperventilating the establishment of an alkaline nasal p H was a dominant finding in infants and very young children. In the present investigation, an unusual opportunity to study the p H of nasal secretion in situ in a group of 13 newborn infants, ranging from 2 to 8 days in age, was provided by the nursery of a metropolitan hospital. The subjects were 7 male and 6 female infants. Although all 13 newborn infants had normal intranasal structures, 1 of the group had cerebral edema and another an occipital encephalocele. All the children were born by the vaginal route more...
