MORILLA GUZMAN, Andrés Armando et al. Use of porcine surfactant in preterm newborns with early-onset bronchopneumonia. AMC [online]. 2015, vol.19, n.4, pp. 348-356. ISSN 1025-0255.

Background: there are disagreements about the use of surfactant in bronchopneumonia in newborns. Objective: to evaluate the behaviour of newborns with early bronchopneumonia treated with exogenous surfactant. Methods: an open, multicentric, non-randomized or controlled study was conducted in 39 preterm newborns with early bronchopneumonia treated with exogenous surfactant. The gestation age, the birth weight and the stay time in the neonatal intensive care unit, the relation PaO2/FiO2, the mechanical ventilation time, the complications of ventilatory support and the mortality according to the number of doses of exogenous surfactant and the use of prenatal steroids were studied. The absolute and relative frequencies, the average and the chi-squared test were calculated. Results: the need of administrating a greater number of doses was associated to a lower relation PaO²/FiO² (p=0,0103). Adequate values were obtained with the first and the second doses. The use of prenatal steroids was associated to a lesser time with mechanical ventilation (p=0,0474), to greater values of the relation PaO²/FiO² (p=0,0162) and to a lower mortality (p=0,0076). No statistical association was found in the complications related to ventilation. Conclusions: those patients who required a greater number of doses of surfactant had an unfavorable ventilatory response and a greater mortality. The use of prenatal steroids favoured a better ventilatory response and a lower mortality. The combination of prenatal steroids and exogenous surfactant can be beneficial in preterm newborns with early bronchopneumonia.
