Maturational changes in physiologic and behavioral responses of preterm neonates to pain.
PURPOSE: To identify physiologic and behavioral responses of preterm infants to a routinely administered painful stimulus (heelstick) to determine how postconceptional age (PCA) may influence pain responses.SUBJECTS: Nonprobability convenience sample of I I preterm infants born at 24-26 weeks PCA.DE...

Additionally, the Premature Infant Pain Profle (PIPP) was used as a composite measure to assess pain.PRINCIPAL RESULTS: Heart rate increased, whereas oxygen saturation and respiratory rate decreased during the most invasive phase of the procedure for infants between 27-32 weeks PCA. Increased PIPP scores and increased brow bulge and eye squeeze were also noted during the stick/squeeze phase. Finger splay increased significantly in magnitude of occurrence between 27-32 weeks PCA, whereas other NIDCAP variables, physiologic measures, facial variables, and PIPP scores were not sensitive to differences in PCA.CONCLUSIONS: Former 24- to 26-week preterm infants who are between 27-32 weeks PCA are capable of expressing pain through physiologic measures and facial actions in a manner similar to more mature preterm and healthy term infants. The PIPP is a valid instrument for assessing pain in infants as young as 27-32 weeks PCA. pubtype: Academic Journal doctype: research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
