Treatment of septic patients : fluids, blood and timing of antibiotics

Sammanfattning: Background: Fluid therapy is an important component of the treatment of septic shock. The Surviving Sepsis Campaign recommends early fluid resuscitation with at least 30 ml/kg and there is no recommendation on when to stop giving fluids. Many studies have shown an association between fluid overload and morbidity and mortality. Clinicians base fluid prescription on variables that do not reflect fluid responsiveness. Aim: The overall intention was to explore what scientific support there is for the treatment of septic patients in terms of their fluid management and the timing of antibiotics and to investigate new tools that could help the clinician decide on the amount and timing of blood and other fluids in septic shock. Overview of methods: See image in thesis pdf Summary of research results: The scientific support for how fluid management in patients with septic shock should be performed is poor. • It is safe to adopt a Hb threshold of 7 g/dl in septic ICU patients except in patients with preexisting cardiovascular disease for whom a transfusion threshold of 8 g/dl is suggested. • It is uncertain whether fluid overload is associated with mortality at a median fluid balance of 2.5 l on day three. • It has not been proven that protocolised haemodynamic management improves outcome. • It was possible to use the protocol based on a passive leg raising (PLR) test, but the recruitment rate was low. The weight gain was low in both the PLR and the control groups. • Female patients and patients with surgical sepsis were overrepresented in the group that received antibiotics after more than one hour in the emergency department. We could neither confirm nor exclude a survival benefit from early administration of antibiotics.
