Abstract/OtherAbstract:
Aims:  To document the effect of position on oxygen saturation and changes in oxygen requirement in convalescent preterm infants. Methods:  Twelve infants born ≥ 24 and ≤ 32 weeks gestation, extubated and without congenital anomaly were studied using nap polysomnography in prone and supine, two-weekly until discharge. Mean oxygen saturation (SpO(2) ), minimum SpO(2) , mean minimum SpO(2) and time with SpO(2) < 90% were measured in Active Sleep. Results:  Eight male and four female infants (median gestation 28 (24-31) weeks and median birthweight 1059 (715-1840) grams) had 39 studies. For 21/39 studies the infant was on respiratory support. Four infants had chronic lung disease. SpO(2) varied with postmenstrual age (p=0.003) but not position (p=0.36) and postmenstrual age did not influence the effect of position on SpO(2) (p=0.19). SpO(2) was lower for those with chronic lung disease (p<0.0001) and those on respiratory support (p<0.001) but there was no effect of position (p=0.97 and p=0.67 respectively). From 36 weeks postmenstrual age, a change to supine did not increase oxygen requirement. Conclusions:  In very preterm infants postmenstrual age and residual respiratory disease have greater effects on oxygenation than position. A supine sleep position is not disadvantageous for preterm infants at discharge.
