AMADOR ALVAREZ, Deidad E.; GUTIERREZ CORZO, Tania  and  ROIG ALVAREZ, Tania. Morbidity and mortality of newborn conceived by in vitro fertilization. Rev Cubana Obstet Ginecol [online]. 2010, vol.36, n.2, pp. 51-61. ISSN 0138-600X.

Assisted reproduction is associated with a high risk of neonatal morbidity and mortality basically with prematurity and a low birth weight increasing markedly in newborns conceived by this procedure. OBJECTIVE: To identify the morbidity and mortality of this group and the differences in some indicators of hospital morbidity with those naturally conceived. METHODS: A transversal, prospective and descriptive study was conducted including 49 neonates conceived by in vitro fertilization (IVF) technique. RESULTS: Rate of multiple pregnancies and of cesarean section was high in those conceived by IVF compared with remainder live births (27% versus 1.4%; p < 0.000 and 97.3% versus 40.9%; p < 0.000, respectively). Most of neonates were term born (71.4%), with a good weight (61.2%) and with a eutrophication nutrition assessment (85.7%). The 28.5% showed morbidity with predominance of a severe icterus 20,4%); the 6.1% deceased (two from hyaline membrane disease and one from intraventricular hemorrhage). There was a higher ratio of prematurity, low weight, restricted intrauterine growth, hyaline membrane disease, congenital malformations and neonatal mortality in those conceived by IVF ( p < 0.05) in all of them. CONCLUSIONS: In present research was confirmed that the newborn artificially conceived have significant influence in hospital indicators related to neonatal morbidity and mortality of institutions where they are seen, thus, hospitals with this responsibility need a logistic support and differentiated health objectives.
