Clinical status of PDA when various Dopller PDA patterns were initially documented during first 7 days of age
| Clinical status of PDA | PH (n=48) | Growing (n=27) | Pulsatile (n=29) | Closing (n=58) | Closed (n=66) |
|---|---|---|---|---|---|
| NS-PDA group (n=37) | 24 | 72-150 | 0** | 31 | 37 |
| S-PDA group (n=31) | 24 | 202-150 | 29** | 27 | 292-151 |
| With S-PDA | 0 | 4 | 20 | 0 | 0 |
| Subsequent S-PDA | 24 | 16 | 9 | 0 | 0 |
Values are number of infants with documented various Doppler PDA patterns.
All the closing and closed patterns in the S-PDA group were the result of treatment, and all non-clinically significant.
↵2-151 Another two infants from the S-PDA group had a closed pattern that was first documented at 8 days of age.
↵2-150 P = 0.0001; ** P < 0.0001.
