Maternal risk factors and immediate outcome of late preterms

Background: This study was conducted to analyse the immediate outcome of late preterm babies and also to evaluate the various maternal risk factors in these babies so that close monitoring of these babies for the complications is done and immediate problems can be addressed.Methods: Prospective observational study done in level 3 NICU setting for 6 months. All babies born between 34-36/7 weeks are included in the study and they constitute the cases. Term (above 36 weeks 6 days gestation) newborns babies born during the study period are controls. Maternal history is taken in detail. Risk factors during pregnancy including maternal age, gravida, mode of delivery, medical conditions and birth details. Baby details like gestational age, sex, birth weight, and neonatal morbidities are recorded. The babies are either shifted to NICU or to mother's side based depending on the baby's condition. All of them are followed up till discharge.Results: 89 late preterm babies born in the hospital during the study period are included in the study. Out of 89 babies 45are females constituting 50.6% and 44are male babies constituting 49.4%. 20 (22.5%) babies had gestational age between 34-35 weeks.29 babies (32.5 %) had gestational age between 35-36 weeks and 40 babies (45%) are between 36-37 weeks of gestation. 47 babies (52.9%) have birth weight between 1.5-2.49 kg.42 babies (47.1%) have birth weight between 2.5-3.5 kg. The number of babies born by LSCS were 48 (54%) and 41 babies 46% are born through vaginal route.42 babies constituting 48.3% are appropriate for gestational age and 43 babies (49.4%) are small for gestationalage.34 (39.1%) babies required NICU admission and 55 (60.9%) babies did not require NICU admission. Among the maternal risk factors PIH was the commonest risk factor in 22babies (24.7 %), followed by PROM13 (14.6 %), oligohydramnios 6 (6.7 %) ,twin gestation 6 (6.7 %), MSAF 3 (3.4%), IDM 3 (3.4%), Antepartum hemorrhage 3 (3.4%), eclampsia 1 (1.1%) and maternal cardiac disease 1.1%. Neonatal morbidities are 25 late preterm babies had jaundice (28.7%) followed by RDS in 15 (17.2%), sepsis in 9 (10.3%), NEC 2 (2.3%), Hypoglycemia 5 (5.6%) late preterm babies required ventilation/ CPAP constituting 5.7%. Surfactant was used in 2 late preterm babies 2.3%. 87 babies (97.8%) got discharged and mortality is 2.2%.Conclusions: Late prematurity is associated with significant neonatal morbidity.

Ductus arterioso persistente y morbilidades intrahospitalarias en Recién Nacidos de muy bajo peso al nacer

Introducción: El ductus arterioso persistente (DAP) es el defecto cardiocirculatorio más frecuente en prematuros, está inversamente relacionado con la edad gestacional y el peso al nacimiento; y se asocia a diversas complicaciones. Objetivo: Evaluar la morbilidad asociada a la presencia de ductus arterioso persistente (DAP) en Recién Nacidos de muy bajo peso al nacer (RMBPN). Materiales y Métodos: Estudio retrospectivo de casos y controles anidado en una cohorte de RMBPN admitidos en la UCIN, de enero de 2013 a diciembre de 2015. Excluidos RN con malformaciones congénitas, fallecidos en sala de parto, fallecidos el primer día de vida asociados a asfixia perinatal severa y trasladados a otras instituciones. Las características basales fueron: peso, edad gestacional, sexo, control prenatal, hipertensión materna, embarazo múltiple, restricción del crecimiento, corticoide prenatal, ruptura prolongada de membranas, tipo de parto, Apgar. Las morbilidades analizadas fueron: distres respiratorio (SDR), hemorragia pulmonar, enterocolitis necrozante (ECN), hemorragia intraventricular (HIV), sepsis, soporte respiratorio, broncodisplasia pulmonar (DBP), ruptura alveolar, retinopatía del prematuro (ROP), días de internación y muerte. Se consignaron los datos en SSPS 17 y Epi info 7.2, se aplicó la prueba X² o Fischer, t de Student o la prueba de Mann Whitney. Significancia p< 0,05 con intervalo de confianza 95%. Resultados: Se incluyeron 131 RN, con DAP 62 y sin DAP 69, cuyas características basales fueron similares, salvo el uso de corticoides prenatales para el grupo sin DAP (p 0.035) RR 0,7 (0,5-0,9). Los RN con DAP tuvieron SDR (p 0,0003) RR 1,5 (1,1-1,9), hemorragia pulmonar (p 0,024) RR 8,9 (1,1-69), ventilación mecánica (p 0,0001) RR 1,7(1,3-2,2), oxígeno a los 28 días (p 0,001) RR 2,2 (1,3-3,8), mayor duración de NPT (p 0.01), trasfusiones (p 0,01) RR 1,7(1,3-2,2), HIV (p 0,003) RR 2,1 (1,2-3,6), BDP (p 0,0001) RR 2,6(1,5-4,5), y mayor cantidad de días de internación (p 0,008). Riesgo de muerte (p 0,001) RR 3,5 (1,5-8,2). Sin asociación con ENC (p 0,195), ROP (p 0,739), Sepsis clínica (p 0,123) ni sepsis tardía (p 0,12). Conclusión: Los RMBN con DAP tuvieron mayor riesgo de muerte y morbilidades graves en comparación con los que no desarrollaron DAP.

Introduction: Patent ductus arteriosus (PDA) is the most frequent cardiocirculatory defect in preterm infants; it is inversely related to gestational age and birth weight; it is also associated with various complications. Objective: To determine the intrahospital morbidities in very low birth weight infants (VLBWI) with and without PDA. Materials and Methods: This was a retrospective study of cases and controls nested in a cohort of VLBWI admitted in the NICU, from January 2013 to December 2015. We excluded newborns with congenital malformations, who died in the delivery room, who died on the first day of life because of severe perinatal asphyxia or who were transferred to other institutions. The baseline characteristics were: weight, gestational age, sex, prenatal, maternal hypertension, multiple pregnancy, growth restriction, prenatal corticosteroids, prolonged rupture of membranes, type of delivery, and Apgar score. The morbidities analyzed were respiratory distress (RDS), pulmonary hemorrhage, necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), sepsis, respiratory support, bronchopulmonary dysplasia (BPD), alveolar rupture, retinopathy of prematurity (ROP) and death. The data were recorded in SSPS 17 and Epi info 7.2, the X² or Fischer test, Student t test and the Mann Whitney test were applied. Significance was defined as p <0.05 with a 95% confidence interval. Results: We included 131 newborns, 62 with PDA and 69 without PDA, whose baseline characteristics were similar, except for the use of prenatal corticosteroids in the group without PDA (p 0.035) RR 0.7 (0.5-0.9). Newborns with PDA had more RDS (p 0.0003) RR 1.5 (1.1-1.9), pulmonary hemorrhage (p 0.024) RR 8.9 (1,1-69), mechanical ventilation (p 0, 0001) RR 1.7 (1.3-2.2), oxygen at 28 days (p 0.001) RR 2.2 (1.3-3.8), longer duration of TPN (p 0.01), transfusions (p 0.01) RR 1.7 (1.3-2.2), IVH (p 0.003) RR 2.1 (1.2-3.6), BPD (p 0.0001) RR 2.6 1.5-4.5), more hospitalization days (p 0.008) and a risk of death (p 0.001) RR 3.5 (1.5-8.2). No association with was observed with NEC (p 0.195), ROP (p 0.739), clinical sepsis (p 0.123) or late sepsis (p0.12). Conclusion: VLBWI with PDA had a higher risk of death and severe morbidity compared to those who did not have PDA.
