Contrast Induced Nephropathy..Who at risk?


  • Despite the absence of precise prevalence rates, overall trends and risk factors have been observed. Overall, the incidence of CIN is thought to be low in patients with normal renal function, but it can be much higher in patients with underlying renal disease.
    • In the general population, the incidence of CIN is estimated to be 1% to 6%. Among patients with normal baseline renal function, the incidence of CIN is estimated to be < 2%.
    • In chronic kidney disease (CKD), the incidence increases to 12% to 27%.
    • In patients with both CKD and DM, the incidence of CIN may be as high as 50%.
    • Patients with acute MI undergoing angioplasty are at higher risk of CIN than patients undergoing elective interventions. Incidence rates of 15% have been reported in patients undergoing cardiac catheterization.

    Driving Pressure in ARDS: A new concept!

    Driving Pressure and Survival in the Acute Respiratory Distress Syndrome Marcelo B.P. Amato, M.D., Maureen O. Meade, M.D., Arthur S. Slutsky, M.D., Laurent Brochard, M.D., Eduardo L.V. Costa, M.D., David A. Schoenfeld, Ph.D., Thomas E. Stewart, M.D., Matthias Briel, M.D., Daniel Talmor, M.D., M.P.H., Alain Mercat, M.D., Jean-Christophe M. Richard, M.D., Carlos R.R. Carvalho, M.D., and Roy G. Brower, M.D. N Engl J Med 2015; 372:747-755 February 19, 2015 DOI: 10.1056/NEJMsa1410639 BACKGROUND Mechanical-ventilation strategies that use lower end-inspiratory (plateau) airway pressures, lower tidal volumes (V T ), and higher positive end-expiratory pressures (PEEPs) can improve survival in patients with the acute respiratory distress syndrome (ARDS), but the relative importance of each of these components is uncertain. Because respiratory-system compliance (C RS ) is strongly related to the volume of aerated remaining functional lung during disease (termed functional lung size)...
