“…In a similar study, Kamalakkannan showed that the number of patients with EF>45% were 60%. 7 In this study the value of blood lactate after surgery was increased compared to baseline. Blood lactate levels in patients with EF>45% were slightly higher than those with a EF≤45%.…”

“…The levels of mixed VO 2 decreased in both groups after surgery but there was no significant difference in blood lactate and VO 2 in both groups. 7 A study by Holm et al, results showed that the best cut off point for mortality during 30 day due to heart failure and venous oxygen saturation was less than 60.1%, with a sensitivity of 59.3% and a specificity of 82.4%. The negative predictive value was reported about 99.5%.…”

“…Studies have shown that by increasing the collapse of the balance, the progress towards organ defects and death is more. 7 Central venous oxygen saturation and lactate rate have been used as indicators for circulatory failure and it can be repeatedly checked by physicians as a guide to the treatment route. [8][9][10] In recent studies, the change in these data was a satisfactory indicator of the occurrence of a problem especially the problem of CABG in high risk patients.…”

Background: VO2/VCO2 ratio and blood lactate are different indices of adequacy of oxygen delivery to oxygen needs. The aim of this study was to investigate the relationship between serum lactate and VO2/VCO2 in patients undergoing CABG in Ardabil city.Methods: This descriptive-analytical study was performed on 30 patients who underwent CABG at Ardabil city hospital during 2017. Demographic data of patients including age and sex were collected. Standard monitoring included electrocardiogram, invasive arterial pressure, pulse oximetry, end tidal carbon dioxide, temperature and urine output was done. The CAB was carried out through a CPB pump at the time of grafting. Blood lactate and VO2/VCO2 were measured in 3 groups of patients based on number of grafts, EF and serum Creatinine. Collected data analyzed by statistical methods in SPSS version 19. Results: Most of patients were male (86.7%). The mean age of patients was 58.1 years. The blood lactate and VO2/VCO2 values increased after surgery. There was no statistically significant difference in two groups based on number of grafts and serum Cr but it was statistically significant based on E/F. There was a significant correlation between Blood lactate and VO2/VCO2 ratio in patients.Conclusions: The results showed that blood lactate as an indicator for patients status during CABG surgery can be replaced with VO2/VCO2.
