Dynamics of blood gas parameters among preterm infants with complications.
| Blood Gas Parameters | 1st Day | 3rd Day | Stat (p-Value) |
|---|---|---|---|
| FiO2 (n = 24) | 40.00 b (35.00 to 42.50) | 25.00 b (24.50 to 30.00) | 3.74 (0.0002) |
| pH (n = 24) | 7.30 b (7.30 to 7.34) | 7.35 b (7.32 to 7.35) | 2.84 (0.0046) |
| pCO2 (n = 24) | 38.00 b (35.00 to 40.50) | 35.00 b (30.90 to 40.00) | 1.48 (0.1396) |
| pO2 (n = 24) | 49.75 b (45.00 to 50.55) | 55.00 b (55.00 to 58.15) | 2.94 (0.0033) |
| SaO2 (n = 24) | 80.00 b (80.00 to 90.00) | 90.00 b (85.75 to 93.50) | 3.68 (0.0002) |
| HD (n = 24) | 43.75 b (39.95 to 52.28) | 49.10 b (44.83 to 56.09) | 2.39 (0.0170) |
b median (Q1–Q3), Q1 = first quartile, Q3 = third quartile; Wilcoxon matched test; FiO2 = oxygen %; pH = blood gas status; pCO2 = CO2 pressure; pO2 = oxygen pressure; SaO2 = oxygen saturation; HD = hydrogen donor
