Introduction:

Pulmonary surfactant administration is traditionally performed by endotracheal tube, but for years there have been less invasive techniques such as administration by laryngeal mask, aerosolization and tracheal catheterization.

Objectives:

To demonstrate the evolution of three neonates who received pulmonary surfactant via tracheal catheterization and to describe the technique used for its administration.

Case presentation:

Three very low birth weight newborns were attended and admitted to the neonatal intensive care unit of "Iván Portuondo" General Teaching Hospital, at San Antonio de los Baños municipality, with preterm respiratory distress syndrome. All were treated with exogenous pulmonary surfactant, Surfacen®, which was administered by tracheal catheterization using an umbilical catheter. This is a minimally invasive technique that was performed without difficulty and always on the first attempt. The three patients showed clinical, gasometric and radiographic improvement with this form of administration and only one of them had a complication during the procedure, which did not constitute a limitation for its performance. This method allowed maintaining non-invasive ventilation, and endotracheal intubation was unnecessary in neonates. The professionals in charge of performing this technique received previous training.

Conclusions:

Minimally invasive administration of pulmonary surfactant was an effective method that achieved total resolution of respiratory distress in neonates. The procedure used allowed rapid and safe administration of Surfacen®.
