ScvO 2 gap

OBJECTIVE: The objective of this study was to verify whether any parameter among those used as the target for haemodynamic optimisation (e.g., mean arterial pressure, central venous oxygen saturation, systolic or diastolic dysfunction, CO2 gap, lactates, right ventricular dysfunction, and PvaCO2 /CavO2 ratio) is correlated with mortality in an undifferentiated population with sepsis or septic shock. METHODS: An umbrella review, searching MEDLINE, the Cochrane Database of Systematic Reviews, Health Technology Assessment Database, and the JBI Database of Systematic Reviews and Implementation Reports, was performed...

OBJECTIVE: Strategies for red blood cell (RBC) transfusion in patients undergoing cardiac surgery have been traditionally anchored to hemoglobin (Hb) targets. A more physiologic approach would consider markers of organ hypoperfusion. DESIGN: The authors conducted a systematic review and meta-analysis with trial sequential analysis of randomized controlled trials (RCTs). SETTING: Cardiac surgery. PARTICIPANTS: Adult patients...

BACKGROUND: To observe the correlation of central venous oxygen saturation (ScvO2 ), serum lactate, standard base excess (SBE), and anion gap (AG) in septic and septic shock patients resuscitated with early goal-directed therapy (EGDT). MATERIALS AND METHODS: A review was made of 130 severe septic shock patients (15-65 years) according to the consensus conference criteria admitted in intensive care unit. Blood samples were obtained from arterial and central venous line for ScvO2, serum lactate, SBE, and AG on admission and after achieving all aims of EGDT i...

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)...
