Table 1. Comparison of physiological variables between infants who later developed intraventricular haemorrhage (IVH) and those who did not (non-IVH).
| Variable | IVH (n = 7) | Non-IVH (n = 20) | p |
|---|---|---|---|
| Gestational age (weeks) | 26.8 ± 1.2 | 26.9 ± 1.8 | 0.781 |
| Birthweight (g) | 1120 ± 282 | 1029 ± 293 | 0.580 |
| Sex (% male) | 57.1 ± 49.5 | 65.0 ± 47.7 | 0.741 |
| CRIBII | 9 ± 1 | 9 ± 2 | 1.000 |
| PDA (%) | 85.7 ± 35.0 | 80.0 ± 40.0 | 0.774 |
| RDS | 1.0 ± 0.0 | 1.0 ± 0.0 | 1.000 |
| Apgar 1-min | 6 ± 1 | 6 ± 2 | 0.696 |
| Apgar 5-min | 7 ± 1 | 7 ± 1 | 0.421 |
| MAP (mmHg) | 32.5 ± 6.1 | 35.2 ± 4.7 | 0.422 |
| DBP (mmHg) | 25.0 ± 3.9 | 29.0 ± 4.6 | 0.050 |
| MAPc (mmHg) | 32.1 ± 5.6 | 35.5 ± 4.2 | 0.234 |
| DBPc (mmHg) | 24.6 ± 3.5 | 29.4 ± 4.1 | 0.019 |
Values are reported as mean ± SD. cDenotes detrended features, CRIBII is the Clinical Risk Index for Babies score II, PDA is Patent Ductus Arteriosus and RDS is Respiratory Distress Syndrome. p values are derived from a two-sided Mann-Whitney U-test where significance is defined as p < 0.05.
