, , To evaluate the use of off-label and unlicensed medications in preterm infants hospitalized in a neonatal intensive care unit.
This nonconcurrent cohort study included preterm infants admitted to 3 neonatal intensive care units in 2016 and 2017 who were followed up during the neonatal period. The type and number of medications used were recorded for the entire period and classified based on the Anatomical Therapeutic Chemical. Descriptive and bivariate data analyses were performed to assess associations between the number of drugs used (total, off-label and unlicensed) and the explanatory variables of interest.
Four hundred preterm infants received 16,143 prescriptions for 86 different pharmaceuticals; 51.9% of these medications were classified as off-label and 23.5% as unlicensed. The most prescribed drugs were gentamicin and ampicillin (17.5% and 15.5% among off-label, respectively) and caffeine (75.5% among unlicensed). The results indicated significant associations between the use of off-label drugs and lower gestational age, low birth weight, lower 5-minute Apgar score, advanced resuscitation maneuver in the delivery room and death. The prescription of unlicensed drugs was associated with lower gestational age, low birth weight and 5-minute Apgar score below 7.
Neonates admitted to neonatal intensive care units are highly exposed to off-label and unlicensed medications. Further studies are needed to achieve greater safety and quality of drug therapy used in neonatology.

In preterm infants, the need for intubation and mechanical ventilation is associated with ventilator-induced lung injuries and subsequent bronchopulmonary dysplasia. The aim of the present review was to improve the understanding of the mechanisms of injury that involve cytokine-mediated inflammation to contribute to the development of new preventive strategies. Relevant articles were retrieved from the PubMed database using the search terms "ventilator-induced lung injury preterm", "continuous positive airway pressure", "preterm", and "bronchopulmonary dysplasia". The resulting data and other relevant information were divided into several topics to ensure a thorough, critical view of ventilation-induced lung injury and its consequences in preterm infants. The role of pro-inflammatory cytokines (particularly interleukins 6 and 8 and tumor necrosis factor alpha) as mediators of lung injury was assessed. Evidence from studies conducted with animals and human newborns is described. This evidence shows that brief periods of mechanical ventilation is sufficient to induce the release of pro-inflammatory cytokines. Other forms of mechanical and non-invasive ventilation were also analyzed as protective alternatives to conventional mechanical ventilation. It was concluded that non-invasive ventilation, intubation followed by early surfactant administration and quick extubation for nasal continuous positive airway pressure, and strategies that regulate tidal volume and avoid volutrauma (such as volume guarantee ventilation) protect against ventilator-induced lung injury in preterm infants.
