- W1995505792 abstract "CBFV were studied in the internal carotid arteries with a pulsed Doppler in 23 infants (mean BW=1500 ± 144g) before & after SURF. The Mean (MFV), Mean Bystolic (SFV) & Mean Diastolic (DFV) time averaged CBFV were calculated, CBFV, blood pressures (BP), ABGs, & FiO2 were measured before & after 10 minutes instillation of SURF. MFV increased after SURF in 11 infants & dropped in 12. Three infants developed reverse DFV. Before SURF, the 12 infante who drop the MFV had a lower pH than the other 11 infanta (p=.04). The 11 infants who increaaed the MFV had a drop in the pH (p=.045) during SURF. Incidence of IVH was 30% (5 gr I–II & 2 gr III). Two infants enlarged previous IVH & 4 had new IVH. These 6 infanta were in the group who dropped the MFV. The risk of IVH was higher in the 12 infants who dropped the MFV than in the 11 who increased the MFV (p=.02). Before SURF, the 6 infants who bled had a lower pH (p=.05), a lower BW (p=.05) & a higher FiO2 (p=.04) than infants who did not bleed. Infants who bled had a higher % drop in the BP & in all the CBFV (p=.0l, both). SURF is associated with profound changes in the CBFV depending on pre-existing clinical conditions. Infants who drop the MFV shortly after SURF have a higher risk for developing IVH or increasing previous IVH within 2 days after SURF." @default.
