Table 2 Comparison of serum creatinine level in the studied groups on admission, after 2 days and after 1 week of starting mechanical ventilation

From: Effect of acute kidney injury on weaning from mechanical ventilation in chronic obstructive pulmonary diseases patients with respiratory failure

Serum creatinine (mg/dl) Non AKI (no. = 42)
mean ± SD
AKI (no. = 58)
mean ± SD
Test P value
On admission 0.84 ± 0.18 0.94 ± 0.21 t = 1.79 0.08
After 48 h of MV 0.82 ± 0.15 2.0 ± 0.27 t = 17.80 < 0.001(HS)
After 1 week of MV 0.89 ± 0.17 2.05 ± 0.47 t = 10.78 < 0.001 (HS)
  1. AKI acute kidney injury, MV mechanical ventilation
