title: Sepsis in critical care.
abstract: Sepsis is a syndrome produced by the accelerated activity of the inflammatory immune response, the clotting cascade, and endothelial damage. It is a systematic process that can progress easily into septic shock and MODS. The chemical mediators or cytokines produce a complex self-perpetuating process that impacts all body systems. It is critical for the nurse first to identify patients at risk for developing sepsis and to assess patients who have SIRS and sepsis continually for signs and symptoms of organ involvement and organ dysfunction. Once sepsis has been diagnosed, evidence-based practice indicates initiation of fluid resuscitation. Vasopressor therapy, positive inotropic support, and appropriate antibiotic therapy should be started within the first hour. Within a 6-hour timeframe the goal is stabilization of the CVP, MAP, and UOP to prevent further organ damage. The challenge for nurses caring for septic patients is to support the treatment goals, to prevent added complications including stress ulcers, DVTs, aspiration pneumonia, and the progression to MODS, and to address the patient's and the family's psychosocial needs. As complex as the pathophysiology of sepsis is, the nursing care is equally complex but also rewarding. Patients who previously might have died now recover as vigilant nursing care combines forces with new drug therapies and evidence-based practice guidelines.
