Weight at weaning of preterm infants from incubator to bassinet: a randomized clinical trial.

Objective: To evaluate thermal responses, weight gain, and resting energy expenditure (REE) in preterm infants weaned from an infant incubator to a warming bassinet after reaching a body weight of either 1,500 or 1,600 g, respectively.

Methods: Preterm infants weighing ≤ 1,500 g were randomly allocated for weaning from a convective incubator after reaching 1,500 g body weight (study group) or 1,600 g (controls). Postweaning body temperature was recorded at short intervals.
