Objective: To investigate the prognostic significance of central venous-to-arterial carbon dioxide difference (cv-art CO 2 gap) during septic shock in patients with and without impaired cardiac function. Methods: We performed a prospective cohort study in 10 French intensive care units. Patients suffering from septic shock were assigned to the impaired cardiac function group ('cardiac group', n =123) if they had atrial fibrillation (AF) and/or left ventricular ejection fraction (LVEF) <50% at study entry and to the non-cardiac group ( n =240) otherwise...

OBJECTIVE: To determine whether central venous-to-arterial carbon dioxide tension difference (Pcv-aCO(2)) could still be used as a goal of fluid resuscitation in septic patients who already had ScvO2 greater than 70% after early resuscitation. METHODS: A prospective observational study was performed on 56 septic patients admitted to the Intensive Care Unit (ICU) in a single University Hospital, who already had ScvO2 greater than 70% after early resuscitation. They were divided into two groups, based on whether the patients' initial Pcv-aCO2 was less than 6 mmHg (low gap group) or greater than or equal to 6 mmHg (high gap group)...

OBJECTIVE: It has been argued that venous oxygen saturation from a central venous catheter (ScvO(2)) could be an inexpensive alternative to mixed venous oxygen saturation (SvO(2)). The aim was to evaluate whether ScvO(2) measurements could replace SvO(2) readings after cardiac surgery and to analyze factors influencing any differences found. DESIGN: A prospective observational study. SETTING: A university hospital. PARTICIPANTS: Twenty patients scheduled for elective cardiac surgery...

OBJECTIVE: To test the hypothesis that, in resuscitated septic shock patients, central venous-to-arterial carbon dioxide difference [P(cv-a)CO(2)] may serve as a global index of tissue perfusion when the central venous oxygen saturation (ScvO(2)) goal value has already been reached. DESIGN: Prospective observational study. SETTING: A 22-bed intensive care unit (ICU). PATIENTS: After early resuscitation in the emergency unit, 50 consecutive septic shock patients with ScvO(2) > 70% were included immediately after their admission into the ICU (T0)...
