INTRODUCTION: Sepsis is a systemic inflammatory response related to high mortality rates in the hospital environment. Delayed etiological diagnosis and inadequate antimicrobial therapy are associated with treatment failures. Molecular tests based on polymerase chain reaction are regarded as faster and more accurate procedures than culture techniques for microbial identification, providing a higher rate of therapeutic success. OBJECTIVE: To develop a panel of primers for DNA fragments of sepsis-related microorganisms. METHODS: Primers for amplification of Enterobacter spp., Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Candida spp. were designed and tested for sensitivity and specificity on the basis of their respective standard strains. RESULTS: The intended specificity was obtained for P. aeruginosa, S. aureus and Candida spp primers. Sensitivity tests showed a threshold for detection from 5 ng to 500 fg in blood samples contaminated with microbial DNA. CONCLUSIONS: The molecular panel presented offers the advantage of a flexible 'open' system when compared to other multiplex detection methods.

Sepsis is a very frequent condition and causes high mortality rates and healthcare costs; it is the main cause of death in intensive care units. Clear, improved prognosis was shown for early diagnosed and treated patients. Treatment guidelines are fundamental for appropriate therapy. It is clear that hypoperfusion patients should be hemodynamically optimized; therefore, recognition of hypoperfusion signs is one of the main therapeutic steps. This guideline discusses the current literature and available data regarding the evaluation of hemodynamic parameters.
