Humidity in Incubators for Tiny Infants

Not Applicable
Recruiting
Conditions
Extremely Premature Infant
Interventions
Device: Incubator ambient relative humidity (RH) of 90%
Device: Incubator ambient relative humidity (RH) of 70%
Registration Number
NCT06399861
Lead Sponsor
The University of Texas Health Science Center, Houston
Brief Summary

The objective of the study is to assess 2 different initial incubator humidification protocols for infants \<25 weeks' gestation admitted to the neonatal intensive care unit (NICU). The hypothesis is that a higher starting humidity decreases dehydration and results in no difference in survival or morbidity. Higher (90%) and lower (70%) starting humidity will be compared.

Primary Outcome Measures
NameTimeMethod
Composite safety scorefrom time of admission to the NICU through hospital discharge (about 4-5 months)

A single composite safety score will be reported (mortality and 6 morbidities will be assessed to determine this score). The composite score ranges from 0 to 7, with a higher score indicating a better outcome, as listed below:

* 0 = Infant does not survive

* 1 = Infant survives, has all 6 assessed morbidities

* 2 = Infant survives, has 5 assessed morbidities

* 3 = Infant survives, has 4 assessed morbidities

* 4 = Infant survives, has 3 assessed morbidities

* 5 = Infant survives, has 2 assessed morbidities

* 6 = Infant survives, has 1 assessed morbidities

* 7 = Infant survives, has no assessed morbidities

Morbidities assessed:

* grade III-IV intraventricular hemorrhage (IVH)

* surgical necrotizing enterocolitis (NEC) or focal intestinal perforation (FIP)

* grade III bronchopulmonary dysplasia (BPD)

* treated retinopathy of prematurity (ROP)

* culture-proven late-onset sepsis (LOS)

* patent ductus arteriosus (PDA) ligation

Efficacy as assessed by percent of birth weight lostupon admission to the NICU, postnatal week 2
