Anorectal manometry in premature infants.
Twenty-eight unselected premature infants were subjected to anorectal pressure studies, using an infusion manometric technique, with a view to establishing normal parameters in this age group. Satisfactory rectal and sphincter pressure readings were obtained in all but one case. In all of these there was a normal anorectal reflex. Low birth weight and prematurity do no preclude a normal anorectal reflex as measured by this technique.
