Use of lung ultrasound in neonates during the COVID-19 pandemic.

In the current pandemic, caused by infection with severe acute respiratory syndrome coronavirus 2, ultrasound has played a fundamental role in patients who develop the resulting disease, designated coronavirus disease 2019 (COVID-19). In this study we present ultrasound images of the lungs of neonates with a suspected or confirmed diagnosis of COVID-19, distinguishing between the changes related to COVID-19 and those unrelated to the disease. Ultrasound examinations were performed by a pediatric sonographer.

Characterization of the motor performance of newborns in a neonatal unit of tertiary level.

Objective:: To characterize the motor performance of newborns in a neonatal unit of tertiary level and compare the results to the values recommended by the Test of Infant Motor Performance (TIMP).

Method:: Newborns between 34 and 416/7 weeks of corrected gestational age, breathing spontaneously and presenting state of consciousness 4 or 5, according to Brazelton, were included. TIMP was used to evaluate the motor performance.

Effects of manual hyperinflation in preterm newborns under mechanical ventilation.

Objective: To assess the effects of manual hyperinflation, performed with a manual resuscitator with and without the positive end-expiratory pressure valve, on the respiratory function of preterm newborns under mechanical ventilation.

Methods: Cross-sectional study of hemodynamically stable preterm newborns with gestational age of less than 32 weeks, under mechanical ventilation and dependent on it at 28 days of life. Manual hyperinflation was applied randomly, alternating the use or not of the positive end-expiratory pressure valve, followed by tracheal aspiration for ending the maneuver.
