Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This study compares the effects of two different levels of incubator humidity (70%, and 80% relative humidity) on temperature control and fluid and electrolyte balance in preterm infants born at 28 weeks gestation and less.
The duration of the study is 14 days.
Intervention code [1] 903 0
None
Comparator / control treatment
80% incubator humidity
we start nursing the baby in humidity once the baby is transferred into the isolette.
The baby will be nursed in 80% incubator humidity for seven days. From day 8 onwards, we'll start to decrease the incubator humidity by 10% each day. When the humidity is down to 40% and the baby's body temperature is stable, we'll cease the incubator humidity. We'll be collecting data on the baby's body temperature for 14 days, so the total duration of the study is 14 days.

Outcomes
Primary outcome [1] 1601 0
The primary outcome is to compare the temperature variability in preterm infants nursed in 70% or 80% incubator humidity. This will be reflected by the number of documented low body temperature (<36 degree C) on each day for the first seven days after birth
Timepoint [1] 1601 0
On each day for the first seven days after birth
Secondary outcome [1] 2897 0
1) To compare the degree of evaporative water loss in preterm infants nursed in 70% or 80% incubator humidity in terms of daily fluid requirement, variability from normal serum sodium ranges, and skin integrity.
Timepoint [1] 2897 0
Daily for the first 14 days after birth.
Secondary outcome [2] 2898 0
2) To compare the incidences of positive bacterial cultures from incubators in 70% and 80% incubator humidity.
Timepoint [2] 2898 0
At the start of the study and on day 14.
Secondary outcome [3] 2899 0
3) To compare the difference of visibility of the infant nursed in the two different levels of incubator humidity.
Timepoint [3] 2899 0
Daily for the first seven days after birth.
