RESUMO

Objetivo: Identificar las patologías o condiciones neonatales que influyen en la prolongación de la estancia hospitalaria en una Unidad de Cuidados Intensivos Neonatales (UCIN). Materiales y métodos: Se realizó un estudio observacional, retrospectivo, de casos y controles; en neonatos hospitalizados de la UCIN, durante el periodo 2015 - 2019, considerando sus diagnósticos perinatales y posnatales como factores a evaluar, así como la estancia hospitalaria. Se dividieron dos grupos: casos (estancia prolongada) y controles (estancia no prolongada). Los datos recolectados fueron procesados en el programa SPSS v.23 obteniendo el OR y la Regresión Logística Binaria. Resultados: Se incluyeron 361 neonatos (91 casos y 270 controles), encontrándose significancia en factores perinatales (p<0.05): Peso al nacer (1000g a <1500g, ORa 8.2: IC3.1 - 21.2) y edad gestacional (28 a 31 sem., ORa 18.6: IC4.8-71.4; 32-33 sem, ORa 8.1: IC3.5 - 18.4); y factores posnatales (p<0.05): Síndrome de distrés respiratorio (ORa 10.3:IC 4.8-22.2), Hipertensión pulmonar persistente (OR 32.2:IC 1.8-559.0), sepsis (ORa 7.1: IC 3.1-16.0), Malnutrición neonatal (ORa 10.2:IC 4.7-22.1) y anemia del prematuro (ORa 8.3:IC 2.4-28.1). No alcanzaron significancia: asfixia, taquipnea transitoria del recién nacido, neumonía, neumotórax, displasia broncopulmonar, síndrome de aspiración meconial, conducto arterioso persistente, cardiopatía congénita, hiperbilirrubinemia, hipoglicemia, enterocolitis necrotizante y apnea del prematuro. Conclusiones: El peso al nacer, edad gestacional, Síndrome de distrés respiratorio, Hipertensión pulmonar persistente, sepsis, malnutrición neonatal y anemia del prematuro son factores de riesgo para estancia hospitalaria prolongada.

Objective: Identify neonatal pathologies or conditions that influence the prolongation of hospital stay in a Neonatal Intensive Care Unit (NICU). Materials and methods: An observational, retrospective, case-control study was carried out; in neonates hospitalized in the NICU, during the period 2015-2019, considering their perinatal and postnatal diagnoses as factors to be evaluated, as well as hospital stay. Two groups were divided: cases (prolonged stay) and controls (non-prolonged stay). The collected data were processed in the SPSS v.23 program, obtaining the OR and the Binary Logistic Regression. Results: 361 neonates (91 cases and 270 controls) were included, finding significance in perinatal factors (p<0.05): Birth weight (1000g to <1500g, ORa 8.2: CI3.1 - 21.2) and gestational age (28 to 31 weeks , ORa 18.6: CI4.8-71.4; 32-33 weeks, ORa 8.1: CI3.5 - 18.4); and postnatal factors (p<0.05): RDS (ORa 10.3: CI 4.8-22.2), PHT (OR 32.2: CI 1.8-559.0), sepsis (ORa 7.1: CI 3.1-16.0), Neonatal malnutrition (ORa 10.2: CI 4.7 -22.1) and anemia of prematurity (aOR 8.3: CI 2.4-28.1). The following did not reach significance: asphyxia, transient tachypnea of ​​the newborn, pneumonia, pneumothorax, bronchopulmonary dysplasia, meconium aspiration syndrome, patent ductus arteriosus, congenital heart disease, hyperbilirubinemia, hypoglycemia, necrotizing enterocolitis, and apnea of ​​prematurity. Conclusions: Birth weight, gestational age, RDS, PHPT, sepsis, neonatal malnutrition and anemia of prematurity are risk factors for prolonged hospital stay.
