SANDOVAL C., Alejandra et al. Antibiotics in neonatology. Part I: Dosage recommendations based on the most recent evidence in newborns Advisory Committee on Neonatal Infections, Chilean Society of Infectious Diseases. Rev. chil. infectol. [online]. 2020, vol.37, n.5, pp.490-508. ISSN 0716-1018.

Antibiotics are the most widely used medications in neonates during their first month of life in neonatal units, mainly due to the high risk they present of acquiring serious infections such as sepsis. Most of these antibiotics are used with extrapolated doses based on the suggestions in the adult population and older children, despite the fact that the pathophysiology in newborns is absolutely different. This leads to a higher risk of more adverse effects occurring, which can lead to greater toxicity and therapeutic failures, among others. In the last decade more and more pharmacokinetic studies of antibiotics have been carried out in neonates, this recent evidence has led to new dosage recommendations taking into account the weight and gestational age of the newborn, among other variables, in agreement to the antibiotic studied. Therefore, based on the need to order and summarize the most up-to-date and most evidence-based information on antibiotics in neonates, this document was prepared to facilitate and promote its correct use in neonatal units.
