DIAGNOSTIC TECHNIQUE FOR RESPIRATORY DISTRESS SYNDROME IN MATURE NEWBORN INFANTS IN FIRST MINUTES OF LIFE Russian patent published in 2015 - IPC A61M1/00 A61M25/18 

FIELD: medicine.

SUBSTANCE: biological fluid aspirate is taken from the anterior nasal cavity by placing a 7-8 mm stopper on a soft catheter by means of a mm-ruler. Air 1 ml is taken into a syringe; the catheter is inserted into the anterior nasal cavity at 7-8 mm, and the biological fluid is taken. The catheter is removed, and the biological fluid with the air is ejected from the syringe into test tube No.1. The catheter is washed with 0.85% sodium chloride 5 ml. That is followed by placing a 20 mm stopper on the soft catheter, and the air 1 ml is taken into the syringe, and the catheter is inserted into the deep nasal pharynx at 20 mm. The biological fluid is taken; the catheter is removed, and the biological fluid with the air is ejected into test tube No.2. The concentration of average-molecular peptides (AMP) is measured in test tubes No.1, No.2. If the AMP difference in test tubes No.1 and No.2 makes 0.009±0.001 absorbance units, the mature newborn infant is considered to be healthy. If the AMP difference in test tubes No.1 and No.2 makes 0.018±0.001 absorbance units, respiratory distress syndrome is diagnosed in the newborn infant.

EFFECT: technique provides the most effective diagnosing of the given pathology in the mature newborn infants, including in the meconium-contaminated amniotic fluid aspiration.
