All participants were preterm infants intubated in the delivery room for Infantile Respiratory Distress Syndrome (IRDS). The purpose of this research is to determine a premedication of intubation. This consists of describing a simple and effective method for premedication in the delivery room, using the umbilical vein, directly perforated through the Wharton jelly.

The umbilical vein is punctured to inject drugs efficiently. The access is simple, the umbilical vein is clearly visible, and a blood reflux can be found easily. We used the same equipment required for a peripheral venous injection: 24 gauge cannula, antisepsis, compress, and a syringe with the prepared anesthetic drugs. We report 5 cases of intubations in the delivery room using this method to administer the premedication.

Classified from bad to excellent, depending on the neonates' residual tone, vocal chords mobility, and persistence of movements while inserting the tube.

The investigators measure the time in seconds between insertion of the tube and the end of fixation.
