Abstract
Venoarterial carbon dioxide gradient utility as a criterion for blood transfusion at the intensive care unit
Highlights
To analyze de utility of the venoarterial carbon dioxide gradient (V-a PC02) to detect those patients who will respond with a rise of Sv02 to blood transfusion
Receiver Operating Characteristic (ROC) curve analysis were performed resulting in an area under the curve of 0.82 (p < 0.01; CI 0.73-0.91) with a pre transfusion V-a PC02 cutoff value of ≥6 showing a sensibility 66% of and a specificity of 84% for predicting those patients who will not respond with a rise greater than 5% in the post transfusion Sv02
V-a PC02 >6 mmHg identifies those patients that will no show a rise of the Sv02 as a response to blood transfusion
Summary
JL Navarro1*, A Sanchez-Calzada, R Gastelum, L Delgado, O Torres, P Romano, E Monares, C Gilberto, J Franco. Intr Currently there is controversy about criteria for blood transfusion in critically ill patients by a level of hemoglobin and specially as a strategy to raise the venous oxygen saturation (Sv02)
