Abstract/OtherAbstract:
Postmature infants calm less when presented with sucrose solutions than term infants. To further assess the influence of postmaturity on sucrose responsivity, several motoric responses were examined in healthy term neonates and chronically stressed postmature (> or = 288 days gestational age (GA) e.g., > 41 weeks) neonates with Clifford's Syndrome tested between 5-91 h of age. Following baseline observations, each subject was presented with 0.1 ml of a 14% sucrose solution for 10 s each min for 5 min, and observations were continued for 5 min following stimulation. During sucrose stimulation and poststimulation phases, postmature infants showed more tremors during quiet state than term infants. Across conditions, postmature infants exhibited increased finger sucking, rhythmic sucking, but less mouth opening and arm movements than healthy, term infants. Sequence analysis revealed that short-latency mouthing, repetitive movements of the upper and lower lips, followed sucrose infusion reliably in postmature infants, but not term infants. These results suggest that postmaturity is associated with: 1. Increased oral behaviors associated with arousal and self soothing; and 2. Increased sucrose reactivity, as indicated by contingent mouthing and increased tremors.
