Table 2. Protein and phospholipid content of bronchoalveolar lavages.

Mean ± SEM protein and phospholipid values (µg/ml) in pre- and post-surfactant treatment bronchoalveolar lavage (BAL) fluids.

SMB-nCPAP	358 ± 96	1,796 ± 431*	45 ± 22	357 ± 147*
SMB-MV	296 ± 42	1,394 ± 259*	9 ± 1	437 ± 100*
BC-nCPAP	368 ± 58	1,731 ± 283*	33 ± 18	1,281 ± 172*,**
BC-MV	354 ± 54	1,092 ± 139*	34 ± 13	1,061 ± 157*,**

Notes.

^*p < 0.001 vs pre-treatment values.

^**p < 0.02 vs post-treatment SMB surfactant.
