Background and Aims
Diaper weighing is used to estimate diuresis in preterm infants; however,
studies have shown that this method is not adequate because absorption
occurs in incubators with high humidity (80%) and its efficacy is
questioned. However, most of these studies evaluated open disposable
diapers, with the absorption surface exposed, not with the closed
disposable diapers, a position that would be an alternative to decrease
the absorption of the atmosphere humidity. Closed diapers for
measurement of diuresis is a routine in our service, used even with the
presence of umbilical catheters.
Aim: To asses the closed disposable diapers absorption in incubators
with humidification to 80%.
We analyzed a total of 40 diapers (without patients), in 2 groups of 20
diapers, exposed for a period of 6 hours in incubators at 37 degrees of
temperature with 80% humidification. The diapers were weighed in a
high precision scale (BG8000-Gehaka), before and after humidification,
during the same period.
Group 1) Open disposable diapers.
Group2) Closed disposable diapers.
The open disposable diapers had an average absorption of 2.52 grams and the
closed disposable diapers had an average absorption of 0.48 grams, difference
with significant clinical.
When the incubator is humidified at 80%, closed diapers are a good instrument for measuring diuresis in premature babies, presenting lower absorption rate than open diapers.
