Improving newborn skin health: Effects of diaper care regimens on skin pH and erythema.

BACKGROUND/OBJECTIVE: Newborn infant skin is functional but immature, and diapering products can play a significant role in infant diapered skin health. Previous work demonstrated a regimen consisting of a diaper with an emollient and apertures on the inner liner (topsheet) with an acidic, pH-buffered wipe (Regimen A) lowered newborn skin pH and reduced the enzymatic activity on skin post-stool cleaning versus a regimen without these features (Regimen B). This study extends these findings to determine the impact of Regimen A on diaper area erythema severity over a 2-week use period. METHODS: This IRB-approved, blinded, randomized, crossover study enrolled newborn infants >7 days and ≤8 weeks. Participants exclusively used two unique diaper and wipe combinations, Regimen A and Regimen B (non-emollient, non-aperture containing topsheet and wipe with limited buffering capacity), each for 14 days and preceded by a 3-day washout regimen. RESULTS: Diapered skin pH was reduced during Regimen A use to values similar to that of a non-diapered control site (chest), while use of Regimen B was associated with a more alkaline skin pH. Regimen A resulted in significantly fewer severe erythema episodes. At the site of highest erythema, the perianal space, the average erythema score was significantly lower and more newborns were free of erythema while using Regimen A vs. Regimen B (P < .05). CONCLUSIONS: These findings demonstrate that diapering products can have a significant impact on newborn skin. They reinforce the need to support the physiological normalization of skin pH and protection from skin irritation and damage.

Use of an emollient-containing diaper and pH-buffered wipe regimen restores skin pH and reduces residual enzymatic activity.

BACKGROUND/OBJECTIVES: Diaper dermatitis is one of the most frequent skin conditions affecting infants and is associated with elevated skin pH, exposure to urine and feces, and increased fecal protease and lipase activity, resulting in stratum corneum barrier damage and increased risk of infection. The study aim was to determine the impact of two diaper and wipe regimens on newborn infant skin pH and residual enzyme activity after stool cleaning. METHODS: Two diaper and wipe regimens were compared in a randomized, single-blinded crossover study. Regimen A paired an emollient-containing diaper with an acidic, pH-buffered wipe. Regimen B was a non-emollient diaper and wipe with limited buffering capacity. A 3-day washout period preceded each 3-day regimen use period. Skin pH at the perianal/buttocks interface (PBI), genital region, and undiapered chest control were measured at baseline and day 3. Skin swabs were collected for residual enzyme activity after a stool cleaning event. RESULTS: Diapered skin pH at the PBI was similar to undiapered skin after 3 days of use for Regimen A, while PBI pH for Regimen B was elevated versus control. PBI pH was lower for Regimen A versus Regimen B. After a stool cleaning, PBI skin pH for Regimen A was lower immediately and had lower residual enzyme activity versus Regimen B (P < .05), and the pH-lowering effect was sustained up to 60 minutes. CONCLUSIONS: These results suggest that the use of an emollient-containing diaper with a pH-buffered wipe creates conditions favorable to optimum diapered skin health.

Characterizing Exclusively Breastfed Infant Stool via a Novel Infant Stool Scale.

Analysis of stool has long been a diagnostic tool across a number of disease states. Currently, there are two stool scales in clinical use, the Bristol Stool Scale and the Amsterdam Infant Stool Scale. However, the existing categorizations for stool may not sufficiently cover the broad range of stool output for exclusively breastfed infants. The Bristol Stool Scale is not age specific to cover children who are not toilet trained and the Amsterdam Infant Stool Scale, though developed for children who are not toilet trained, does not sufficiently cover the wide variety of consistencies of exclusively breastfed infant stools. Through a robust understanding of exclusively breastfed infant stool characteristics, a new stool scale has been developed. It is proposed that this stool scale may better assist in observing and recording exclusively breastfed infant stool in a more accurate manner, which may aid in diagnostic capabilities.

The impact of diaper design on mitigating known causes of diaper dermatitis.

BACKGROUND: Diapers play a critical role in infant health. In addition to providing sanitary methods of disposing of urine and feces, they can also directly impact skin health. Prolonged exposure to wetness and fecal matter has been shown to be a key driver of diaper dermatitis. This study sought to evaluate how diaper construction can affect absorption of stool. METHODS: Methods included laboratory testing of stool absorbency as well as an at-home diaper evaluation study, which examined a diaper's ability to keep fecal matter from the skin. Breastfed infant stool was given special consideration, as its properties make it difficult to contain. RESULTS: Laboratory results demonstrated that a meshlike aperture diaper was better able to absorb fecal matter. The at-home diaper evaluation study confirmed that a meshlike aperture diaper design resulted in fewer instances of stool being present on skin during diaper changes. CONCLUSION: Diapers with a meshlike aperture topsheet may represent a better way to mitigate known causes of diaper dermatitis through their superior ability to absorb fecal matter.

Improving Diaper Performance for Extremely Low-Birth-Weight Infants.

BACKGROUND: Extremely low-birth-weight (ELBW) infants face significant diapering challenges compared with their full-term peers, due to immature musculature, nervous system, and skin development. Advances in medical care have increased an ELBW infant's rate of survival, which creates a growing need for diapers to better serve these infants. Aim of research. The objective of this study was to identify and confirm the requirements for optimal diaper performance from the neonatal intensive care unit nurses' perspective, as well as to assess in-hospital performance to determine if new features improved key developmental care parameters. METHOD: Two surveys were shared among nurses to address study objectives. Study 1 (N = 151) was designed for neonatal intensive care unit nurses to identify key requirements for ELBW diapers and rate the performance of existing ELBW diapers. Study 2 (N = 99) assessed in-hospital performance of the test diaper compared with the usual diaper, under normal usage conditions. Findings/results. The majority of nurses agreed that ELBW diapers must fit appropriately between the legs so that hips and legs are not spread apart and that ELBW diapers need to be flexible between the legs for positioning. Of the nurses-infant pair responses, 93% ( P < .0001) preferred the test ELBW diaper over their usual diaper. CONCLUSION: Findings suggest that nurses should be included in the product design process to ensure both their needs and the needs of an infant are being met. Nurses are considering how diaper features may affect both acute and long-term medical outcomes and this information provides necessary guidance to diaper manufacturers and designers when developing better-performing diapers.
