antibiotic therapy in septic shock

Bochud PY, Bonten M, Marchetti O, Calandra T. Antimicrobial therapy for patients with severe sepsis and septic shock: an evidence-based review. Empiric antibiotic treatment reduces mortality in severe sepsis and septic shock from the first hour: results from a guideline-based performance improvement program. Early broad-spectrum antimicrobial therapy is necessary within the ‘golden hour’ in septic shock and, as a milestone, reduces mortality. Chest 2010;38:1773–85. After culture results are known, the antibiotic regimen should be narrowed to cover the specific infecting microorganism using the least expensive, least toxic antibiotic available. (e.g., broader antibiotics are generally warranted in critically ill patients, such as those with septic shock or respiratory failure); and each hospital’s local antibiogram and pharmacy formularies. The advent of modern antimicrobial therapy following the discovery of penicillin during the 1940s yielded remarkable improvements in the case fatality rates of serious infections, including septic shock. Organized antibiotic order sets have been shown to significantly improve timely appropriate antibiotic administration in septic patients. No studies to date have exclusively targeted septic oncologic patients without hypotension. Infections with gram-negative bacteria appear to be associated with septic shock more than any other etiologic agent; therefore, antibiotic selection must include those drugs with superior gram-negative coverage.

Sepsis is one of the major health problems of the 21 st century. Combined antibiotic therapy is widely used in clinical practice and is aimed at widening the spectrum of activity of antimicrobial therapy, increasing bactericidal activity, and preventing the development of resistance. Antibiotic therapy for gram-negative bacteremia. Initial antimicrobial therapy in septic shock should begin with the maximum recommended dose taking into account any increased predisposition to toxicity in a given critically ill patient. In patients with ongoing sepsis or septic shock an early and appropriate empirical antibiotic therapy has a significant impact on the outcome, independently by the site of infection.

Otherwise, appropriate empiric therapy of culture-negative infections leading to septic shock was based on the recommendations listed in the “Clinical Approach to Initial Choice of Antimicrobial Therapy” in the Sanford Guide to Antimicrobial Therapy 2004 (34th edition). This study demonstrated that initial combination antibiotics for septic shock increased 28-day survival (P = 0.0002) along with pressor free and ventilator free days in the ICU.
