Abstract
- <bold>Study Objective: </bold>To investigate whether optimizing individualized goal-directed therapy (GDT) based on cerebral oxygen balance in high-risk surgical patients would reduce postoperative morbidity.<bold>Design: </bold>This was a prospective, randomized, controlled study.<bold>Setting: </bold>The study was performed in the First Affiliated Hospital of Anhui Medical University, Hefei, China, from April 2017 to July 2018.<bold>Patients: </bold>146 high-risk adult patients undergoing valve replacements or coronary artery bypass surgery with cardiopulmonary bypass (CPB) were enrolled.<bold>Intervention: </bold>Patients were randomized to an individualized GDT group or usual care group. Individualized GDT was targeted to achieve the following goals: A less than 20% decline in the regional cerebral oxygen saturation (rScO2) level from baseline; a less than 20% decline in the mean arterial pressure (MAP) from baseline, as well as a bispectral index (BIS) of 45-60 before and after CPB and 40-45 during CPB.<bold>Measurements: </bold>The primary outcome was a composite endpoint of 30-day mortality and major postoperative complications.<bold>Main Results: </bold>128 completed the trial and were included in the modified intention-to-treat analysis. Early morbidity was similar between the GDT (25 [39%] of 65 patients) and usual care groups (33 [53%] of 63 patients) (relative risk 0.73, 95% CI 0.50-1.08; P = 0.15). Secondary analysis showed that 75 (59%) of 128 patients achieved individual targets (irrespective of intervention) and sustained less morbidity (relative risk 3.41, 95% CI 2.19-5.31; P < 0.001).<bold>Conclusions: </bold>In high-risk patients undergoing cardiac surgery, individualized GDT therapy did not yield better outcomes, however, the achievement of preoperative individual targets may be associated with less morbidity.<bold>Trial Registration: </bold>Clinicaltrials.gov identifier: NCT03103633. Registered on 1 April 2017. [ABSTRACT FROM AUTHOR]
