Objective. Demonstrate that the rate of growth in preterm infants are at a particular time period is greater in nest temperature in relation to the incubator. Material and methods. Clinical trial of simple randomization. The study was conducted in intermediate care facilities and minima of the Neonatology Service, Hospital Materno Infantil of the city of La Paz. Participants in the study 26 patients with a diagnosis of prematurity, 14 patients accepted into the group A (nest temperature) and 12 in group B (incubator), of which 5 were excluded due to bacterial sepsis. The 21 remaining patients, 12 belonging to the group of nest temperature and 9 incubator group were subdivided according to the weight of study entry into two sub-groups: 1: RN weighing between 1200-1500 g. and 2: RN weighing over 1500 g. Once you made the measurement of baseline, patients were divided into two groups by simple randomization, then the protocol is followed according to the flowchart of the study. Measurements were made of weight gain, height, increased head circumference and arm. Results: Patients in Group A subgroup 1 reached its high (1,800 g in weight) by an average of 26.16 days, patients in group B subgroup 1 by an average of 26 days. Patients in group A subgroup 2 received the high (reaching 1800 g weight) by an average of 12 days, infants in group B subgroup 2 in an average of 17.4 days. The time of onset of weight gain in the subgroup 1tuvo a RRR of -100%, RAR - 25%, NNT - 4.The subgroup 2 had a RRR of - 150%, with RAR - 30% and NNT of - 3.3. Conclusions: This research has demonstrated the benefit of the nest temperature (not statistically significant, bias due to the number of patients) in relation to the hatchery, the ponderal weight gain in preterm infants.
