Introduction. Transpulmonary thermodilution using PiCCO (Pulse-induced Contour Cardiac Output) is a standard minimally invasive method used for haemodynamic monitoring. Objectives. The goal of this paper is to examine the correlation and dynamics of the ExtraVascular Lung Water Index (EVLWI) as an indicator of acute lung injury in septic patients who underwent major abdominal surgery. Two groups of patients were selected: the ones with ALI (Acute Lung Injury): ALI patient group, and the ones without ALI: non-ALI patient group. A correlation between EVLWI and other haemodynamic and respiratory data in both groups were analyzed.
Materials and methods. The study included 48 patients. Throughout the seven-day period EVLWI, GEDVI (Global End-Diastolic Volume Index), ITBVI (IntraThoracic Blood Volume Index), CI (Cardiac Index), SVRI (Systemic Vascular Resistance Index) were measured in both groups using PiCCO monitoring over 8-hour intervals as well as heart rate, mean arterial pressure, serum albumin concentration, PaCO2 (arterial partial pressure of carbon dioxide), PaO2 (arterial partial pressure of oxygen), PaO2/FiO2 (arterial partial pressure of oxygen/fraction of inspired oxygen) ratio, lung compliance, lung resistance and ScvO2 (central venous oxygen saturation). All patients were analgosedated, intubated, mechanically ventilated, in sinus cardiac rhythm. Circulatory unstable patients had vasoactive support and Sequential Organ Failure Assessment (SOFA) scores calculated. Ventilator settings and dosage of vasoactive drugs were kept constant during the study.
Results. EVLWI was significantly higher in ALI patients group compared to non-ALI patients group. In patients with ALI group 11/22 patients died (50%), in the non-ALI patients group 6/26 patients died (23%). EVLWI was significantly higher in patients that died compared to ones who survived.
Conclusion. EVLWI is a good indicator of early acute lung injury in surgical patients with sepsis.
