Pediatric acute care nurses questioned the practice of weighing disposable infant
diapers immediately after voiding. This study asked the research question, “Does
volume of saline, diaper configuration, and/or size of diaper statistically effect
changes in diaper weights over time?” The method was an experimental, laboratory
model. Pre-set volumes of saline were added to disposable diapers that were
then left folded or unfolded. Each diaper was weighed immediately post-wetting
and re-weighed at hourly intervals for seven hours. Data were analyzed using a
repeated measures analysis of variance (RMANOVA) with balanced data (F-test).
Diaper weight changes over time were statistically significant for all time points and
for all volumes regardless of diaper size; however, the changes in weight were
small and without clinical significance. It is appropriate to weigh diapers at the end
of eight hours without risk of altering subsequent fluid management of patients in
open-air, non-humidified environments. This practice has led to more efficient use
of nurses' time with fewer interruptions for patients and families.
