Learning Objective 1: The learner will be able to understand the body of knowledge on pH and hydration of cord and skin of high-risk neonates.
Learning Objective 2: The learner will be able to understand the pH and hydration factors in cord and skin care of high-risk infants in terms of infection control.
Methods: After IRB approval and obtaining the informed consent from parents, the pH and hydration of cord and dorsal hand of neonates was measured at 1st, 2nd, 3rd, 5th and 7th day of life using ph meter (HI 99181, HANNA) and hydration meter (National DM-R2, Japan).
Results: The results showed the significant changes in pH (F=199.662, p<.001) and hydration (F=9.460, p=.002) between two sites. The patterns of the changes in pH between two sites significantly differ across 7 days for pH (F=8.804, p<.001), while no interaction in changes in hydration between sites and 7 days of life (F=0.878, p=.478). Small positive relationships were observed in cord (r=.196) and hand (r=.098) between pH and gestation while fairly moderate negative relationships in cord (r=-.330) and hand (r=-.436) between hydration and gestation in high-risk neonates.
Conclusion: The formation of acid mantle at both cord and skin may take more than 7 days of life for high-risk infants. Hydration level differs between cord and skin whil little changes on hydration itself for 7 days per each site. Further analysis is needed to explore the factors on pH and hydration of cord and skin in respect to cord detachment and cord care.
