- W4307014799 abstract "Oxygen saturation and lactate are markers of tissue hypoxia; they are obtained from central venous and mixed venous sample of the pulmonary artery. The simultaneous behavior of these parameters in the postoperative period of cardiac surgery is unknown.To characterize the lactate and oxygen saturation of the venous-arterial circuit of the postoperative patient from cardiac surgery.Design: Analytical cross-sectional. In consecutive patients after cardiac surgery, serum lactate and oxygen saturation of the venous-arterial circuit were obtained. The variables were reported with median (25.75 percentiles). They were analyzed with Kruskal-Wallis ANOVA and respective adjustment, Spearman correlation, the descriptive Bland-Altman statistic and intraclass correlation coefficient (95% confidence interval). A p < 0.05 was considered significant.244 blood samples from 61 patients were studied. Women 30 (49%). (Oxygen saturation) [lactate] were: arterial 98 (95.3, 99.4%) and 1.7 (1.1, 2.1); peripheral venous 85 (75.4, 94%) and [1.9 (1.35, 2.3)]; central venous 68.8 (58.74, 70.2%) and 1.8 (1.3, 2.3); mixed central venous 66.8 (61.2, 73.1%) and 1.8 (1.3, 2.2), p < 0.05. The best intraclass correlation coefficient for oxygen saturation were from central vein to mixed central vein 0.856 (0.760,0.914); and lactate: 0.954 (0.923, 0.972).The oxygen saturation differs in the venous-arterial circuit unlike lactate where they are similar. The best values of the intraclass correlation coefficient for lactate and oxygen saturation were those obtained in central vein and mixed central vein.La saturación de oxígeno y el lactato son marcadores de hipoxia tisular, se obtienen de muestra venosa mezclada en arteria pulmonar o venosa central. Se desconoce el comportamiento simultáneo de estos parámetros en el postoperatorio de cirugía cardiaca.Caracterizar la saturación de oxígeno y lactato del circuito venoso-arterial del paciente postoperado de cirugía cardiaca.Diseño transversal analítico. En pacientes consecutivos postoperados de cirugía cardiaca se obtuvieron lactato sérico y saturación de oxígeno del circuito venoso-arterial. Las variables se informaron con mediana (percentiles 25 y 75). Se analizaron con ANOVA de Kruskal-Wallis y ajuste respectivo, correlación de Spearman, el estadístico descriptivo de Bland-Altman y coeficiente de correlación intraclase (intervalo de confianza al 95%). Una p < 0.05 se consideró significativa.Se estudiaron 244 muestras sanguíneas de 61 pacientes. Mujeres 30 (49%). Saturación de oxígeno y lactato fueron: arterial 98 (95.3, 99.4)% y 1.7 (1,1, 2.1); venosa periférica 85 (75.4, 94)% y 1.9 (1.35, 2.3); venosa central 68.8 (58.74, 70.2)% y 1.8 (1.3, 2.3); venosa central mezclada 66.8 (61.2, 73.1)% y 1.8 (1.3, 2.2), p < 0.05. El mejor coeficiente de correlación intraclase para la saturación de oxígeno fue de vena central a vena central mezclada: 0.856 (0.760, 0.914); del lactato: 0.954 (0.923, 0.972).La saturación de oxígeno difiere en el circuito venoso-arterial a diferencia del lactato, donde son similares. Los mejores valores del coeficiente de correlación intraclase para el lactato y la saturación de oxígeno fueron los obtenidos en vena central y vena central mezclada." @default.
