Detaljeret beskrivelse
The clinical determination of the intravascular volume can be extremely difficult in critically ill patients. Although hemodynamic maximization was proposed, this approach was associated with a risk of fluid overload and excessive inotropic support. Therefore, fluid optimization was seen as a significant step forward and has been shown to decrease complications. Significant effort has been devoted to defining and developing simple means for predicting fluid responsiveness, i.e. whether the patient will benefit from fluid administration. Passive leg raising (PLR), a bedside performed test, could be used to accurately predict fluid responsiveness in most conditions.
However, most parameters that provide information about fluid responsiveness during volume expansion and PLR are invasive and time-consuming. A completely noninvasive and atraumatic parameter to predict fluid responsiveness might be need urgently. Transcutaneous partial pressure of oxygen (PtcO2), a measure to detect tissue ischemia or inadequate perfusion, might reflect the change in cardiac output, thus predict fluid responsiveness. The purpose of this study was to study the feasibility of predicting fluid responsiveness by transcutaneous partial pressure of oxygen in the critically ill patients.
