Morbidity and mortality rates in this population remain high despite significant medical progress. We aimed to evaluate the morbidity and mortality rate in preterm neonates weighing&lt;750g and to evaluate their outcome at 2 years&#8217; corrected age (CA).<\/p>\n\n\n\n<p><strong>Methods:&nbsp;<\/strong>This was a retrospective monocentric study including babies born between May 2011 and April 2013 who were preterm and weighed&lt;750g. We evaluated mortality and morbidity in the neonatal period. At 2 years&#8217; CA, we focused on developmental quotient (DQ) with the Brunet-L\u00e9zine test, on neurosensory assessment (sleeping\/behavior), and growth evaluation.<\/p>\n\n\n\n<p><strong>Results:&nbsp;<\/strong>Among the 107 infants included, 29 (27%) died in the neonatal period. Mean gestational age was 25.6 weeks&#8217; gestation. Female sex and higher birth weight were independent predictors of survival. A total of 61 (78.2%) infants showed extra-uterine growth retardation at 36 weeks&#8217; postmenstrual age. At 2 years&#8217; CA, 57 children were followed up; 38 were evaluated using the Brunet-L\u00e9zine test, 20 (52.6%) had a DQc&lt;85, and none had a severe developmental delay (DQc&lt;50). Six (10%) children had cerebral palsy and 22 of 56 (39.2%) showed language delay. Growth retardation persisted in 15 of 52 (28.8%) children.<\/p>\n\n\n\n<p><strong>Conclusion:&nbsp;<\/strong>Our results confirm the acute fragility of extremely low-birth-weight babies with a high rate of morbidity and mortality. At 2 years&#8217; CA, this population still shows a considerable rate of mild difficulties, whose long-term evolution needs to be followed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Arch Pediatr. 2020 May;27(4):227-232. doi: 10.1016\/j.arcped.2020.02.003.
