Effect of high-dose dexamethasone on perioperative lactate levels and glucose control: A randomized controlled trial

Introduction: Blood lactate levels are increasingly used to monitor patients. Steroids are frequently administered to critically ill patients. However, the effect of steroids on lactate levels has not been adequately investigated. We studied the effect of a single intraoperative high dose of dexamethasone on lactate and glucose levels in patients undergoing cardiac surgery. Methods: The Dexamethasone for Cardiac Surgery (DECS) trial was a multicenter randomized trial on the effect of dexamethasone 1 mg/kg versus placebo on clinical outcomes after cardiac surgery in adults. Here we report a pre-planned secondary analysis of data from DECS trial participants included at the University Medical Center Groningen. The use of a computer-assisted glucose regulation protocol-Glucose Regulation for Intensive care Patients (GRIP

Intraoperative high-dose dexamethasone for cardiac surgery

__Context:__ Prophylactic corticosteroids are often administered during cardiac surgery to attenuate the inflammatory response to cardiopulmonary bypass and surgical trauma; however, evidence that routine corticosteroid use can prevent major adverse events is lacking. __Objective:__ To quantify the effect of intraoperative high-dose dexamethasone on the incidence of major adverse events in patients undergoing cardiac surgery. __Design, Setting, and Participants:__ A multicenter, randomized, double-blind, placebocontrolled trial of 4494 patients aged 18 years or older undergoing cardiac surgery with cardiopulmonary bypass at 8 cardiac surgical centers in the Netherlands enrolled between April 13, 2006, and November 23, 2011. __Intervention:__ Patients were randomly assigned to receive a single intraoperative dose of 1 mg/kg dexamethasone (n=2239) or placebo (n=2255). __Main Outcome Measures:__ A composite of death, myocardial infarction, stroke, renal failure, or respiratory failure, within 30 days of randomization. __Results:__ Of the 4494 patients who underwent randomization, 4482 (99.7%) could be evaluated for the primary outcome. A total of 157 patients (7.0%) in the dexamethasone group and 191 patients (8.5%) in the placebo group reached the primary study end point (relative risk, 0.83; 95% CI, 0.67-1.01; absolute risk reduction, -1.5%; 95% CI, -3.0% to 0.1%; P=.07). Dexamethasone was associated with reductions in postoperative infection, duration of postoperative mechanical ventilation, and lengths of intensive care unit and hospital stays. In contrast, dexamethasone was associated with higher postoperative glucose levels. __Conclusion:__ In our trial of adults undergoing cardiac surgery, the use of intraoperative dexamethasone did not reduce the 30-day incidence of major adverse events compared with placebo

Long-term outcomes and cost effectiveness of high-dose dexamethasone for cardiac surgery: a randomised trial

Prophylactic intra-operative administration of dexamethasone may improve short-term clinical outcomes in cardiac surgical patients. The purpose of this study was to evaluate long-term clinical outcomes and cost effectiveness of dexamethasone versus placebo. Patients included in the multicentre, randomised, double-blind, placebo-controlled DExamethasone for Cardiac Surgery (DECS) trial were followed up for 12 months after their cardiac surgical procedure. In the DECS trial, patients received a sing

Preoperative anaemia and outcome after elective cardiac surgery: a Dutch national registry analysis

Background: Previous studies have shown that preoperative anaemia in patients undergoing cardiac surgery is associated with adverse outcomes. However, most of these studies were retrospective, had a relatively small sample size, and were from a single centre. The aim of this study was to analyse the relationship between the severity of preoperative anaemia and short- and long-term mortality and morbidity in a large multicentre national cohort of patients undergoing cardiac surgery. Methods: A nationwide, prospective, multicentre registry (Netherlands Heart Registration) of patients undergoing elective cardiac surgery between January 2013 and January 2019 was used for this observational study. Anaemia was defined according to the WHO criteria, and the main study endpoint was 120-day mortality. The association was investigated using multivariable logistic regression analysis. Results: In total, 35 484 patients were studied, of whom 6802 (19.2%) were anaemic. Preoperative anaemia was associated with an increased risk of 120-day mortality (adjusted odds ratio [aOR] 1.7; 95% confidence interval [CI]: 1.4–1.9; P<0.001). The risk of 120-day mortality increased with anaemia severity (mild anaemia aOR 1.6; 95% CI: 1.3–1.9; P<0.001; and moderate-to-severe anaemia aOR 1.8; 95% CI: 1.4–2.4; P<0.001). Preoperative anaemia was associated with red blood cell transfusion and postoperative morbidity, the causes of which included renal failure, pneumonia, and myocardial infarction. Conclusions: Preoperative anaemia was associated with mortality and morbidity after cardiac surgery. The risk of adverse outcomes increased with anaemia severity. Preoperative anaemia is a potential target for treatment to improve postoperative outcomes
