Abstract
The aim of this study was to assess the vitality and lung function of preterm lambs. Twenty seven preterm lambs were divided in four groups. Group I (n=6) preterm lambs/ control; group II (n=9) lambs born to mothers that were treated with dexamethasone antepartum; group III (n=6) lambs treated with surfactant; and group IV (n=6) lambs treated with surfactant and born to mothers that were treated with dexamethasone antepartum. The APGAR score was performed after birth (T 0 ) and 15 minutes later (T 1/4 ) to assess vitality. The vital signs, blood gas analysis, spirometry and capnometry were assessed immediately after birth and continued until 48 hours. Chest radiographs were performed at T 0 , T 24 and T 48 . Significant rectal temperature interactions occurred at T 1 and T 6 depending on the type of treatment used. All animals showed low pH values, which were associated with high pCO 2 values and HCO 3 -values that increased over time from immediately after birth to two days of age. Higher tidal volume values were observed at T 1/4 , T 1 and T 24 when the animals were not treated with surfactant. Capnometry showed significant interactions between treatments at T 0 . Premature animals showed low vitality and impaired pulmonary function.
