title: [High-frequency oscillating ventilation in premature infants under 1500 gram birth weight].
abstract: In 58 premature infants with a birthweight < 1500 g High-Frequency-Oscillating-Ventilation (HFOV) was initiated within the first 48 hours of life. Indications for HFOV were: no response to surfactant application (N = 41), respiratory distress syndrome without surfactant application (N = 9), pulmonary interstitial emphysema (N = 8). Mean gestational age of the enrolled patients was 27.6 weeks (24-32) and mean birthweight was 964 g (490-1450). 23 infants died, 5 from non-pulmonary causes. Of the remainder 2 had B-Strept.-septicemia, 1 lunghypoplasia, and 1 patient died on the 70th day of life from chronic lung disease. There were no statistical differences between survivors and nonsurvivors in gestational age, birthweight, umbilical pH, 1 min APGAR score or time on conventional ventilation prior to HFOV. Alveolar-arterial-O2-difference dropped in the group of surviving patients from x487 mm Hg (sd +/- 60) to 252 mm Hg (sd +/- 89) after 6 hours (p < 0.0001) and in the nonsurvivors from x517 mm Hg (sd +/- 74) to x373 mm Hg (sd +/- 106) (p = 0.002). Oxygenationindex fell from x25 (sd +/- 10) to x5 (sd +/- 1.5) in the survivors and from 25 (sd +/- 11) to x9 (sd +/- 5.5) in the nonsurvivors within 6 hours (p < 0.0001). Mean airway pressure could be lowered in survivors from x7.6 cm H2O (sd +/- 0.6) to 5.3 cm H2O (sd +/- 0.8) and in nonsurvivors from x8.6 cm H2O (sd +/- 0.6) to 5.7 cm H2O (sd +/- 0.9) (p = 0.0002). The promising results of HFOV as a rescue therapy require a controlled study for its use as a primary mode of ventilation in premature infants.
