 To date, no studies have attempted to answer this important question by comparing standard doses to renally adjusted doses of empiric antibiotics in patients with both septic shock and renal dysfunction during the initial resuscitative period. Currently there is no uniform practice among clinicians with respect to antibiotic dosing, which reflects the paucity of evidence in this area. Some clinicians currently use full dosing of antibiotics in the setting of septic shock with acute renal failure while others adjust the dose based on renal function. Well designed, prospective, randomized controlled trials are urgently needed to clarify the role of antibiotic adjustment during the resuscitative period of septic shock.
