Determinants of dysfunction in PMV patients: underlying factors and acute insults

Underlying renal insufficiency	Acute insults
Age	Post-surgical (mostly post-CABG)
Diabetes	Cardiac arrest
Hypertension	Sepsis/MOSF
Congestive heart failure	Hypotension
Renal artery stenosis	Antibiotic toxicity
Renal allograft dysfunction	Renal allograft rejection
Glomerulonephritis	Cholesterol emboli

MOSF = multiple organ system failure; PMV=prolonged mechanical ventilation; CABG=coronary artery bypass graft.
