Transient Hypothyroxinemia of Prematurity (THOP)
Study of Thyroid Hormones in Prematures
The investigators hypothesize that continuous infusion of 4 µg/Kg/day T4 with 30 µg/Kg/day oral potassium iodide (KI) for 42 days from birth will reduce by 30% or more (from an estimated 30% to 21%) the proportion of extremely…

Transient Hypothyroxinemia of Prematurity
Neurodevelopmental Impact of Treatment in Hypothyroxinaemia of Prematurity.
Nowadays, taking care of preterm birth is associated with an important increase in survival. This increased survival comes with impairment in neurodevelopmental outcomes in long term evaluation.

- Testing
- L-thyroxine at a dose of 7.5 µg/kg/d for THOP, THOP without treatment, NoTHOP
