OBJECTIVE:

To provide the reader with ample and sufficient information about this syndrome, with emphasis on the recognition of fetal multiorgan damage, to provide tools to establish a timely diagnosis and reduce fetal and neonatal morbidity and mortality.

METHODOLOGY:

Retrospective study based on the search in PubMed, EBSCO and Ovid databases from 2016 to 2021 of review articles, original research, practice guidelines and protocols. In addition, classic articles and those corresponding to manual searches to achieve contextualization of the points discussed.

RESULTS:

When infection reaches the fetus, a proinflammatory response with cytokine secretion unfolds, which are the basis for the diagnosis of fetal inflammatory response syndrome. When this response to infection is deregulated, it ends up generating multiorgan damage that can be recognized by means of noninvasive tools, such as advanced fetal ultrasound. This recognition allows initiating timely care in order to reduce perinatal morbidity and mortality rates.

CONCLUSION:

Microbial infection of the amniotic cavity and fetus, with subsequent generation of fetal inflammatory response syndrome, is associated with multiorgan damage that can be recognized on advanced ultrasound and achieve optimal care and better perinatal outcomes.
