1781 The Predictive Factors in the Progress of Transient Tachypnea of the Newborn

Aim To determine the clinical risk factors to predict the progress of TTN in late-preterm and term infants. Methods The infants with the diagnosis of TTN were evaluated retrospectively. Patients were divided into two groups according to the intensity of respiratory support. Group-1 received any ventilatory support, where group-2 only oxygen. Clinical findings, Richardson and Silverman scores were compared. Results One-hundred-six (19.1%) infants were evaluated (68 in group-1, 38 in group-2). Mean gestational age and birth weight were lower in group-2. The C/S and male gender rates were similar. Richardson scores, Silverman scores, peak-respiratory rates (pRR) and oxygen need (FiO2) in the first 24-hours were higher, duration of respiratory support and hospitalization were longer in group-1. The cut-off for Richardson score was 3, and patients whose score higher than 3 had a 6.98-fold-risk, the cut-off for Silverman score was 5 and whose score higher than 5 had a 7.46-fold risk, and the cut-off for pRR in first 24-hours was 75/min and whose pRR was higher than 75/min in first 24-hours had a 1.10-fold risk of receiving ventilatory support (95%CI: 2.30–21.18, 2.54–21.89, and 1.035–1.17, p
