Background: Traditionally, physical movement has been limited for cardiac surgery patients, up to 12-weeks post-operatively. Patients are asked to use “standard sternal precautions,” restricting their arm movement, and thereby limiting stress on the healing sternum. Aim: To compare return to function, pain/discomfort, wound healing, use of pain medication and antibiotics, and post-operative length of hospital stay in cardiac surgery patients having median sternotomy who used standard sternal precautions or Keep Your Move in the Tube movement protocols post-operatively. Methods: A quasi-experimental design was used (100 standard sternal precautions and 100 Keep Your Move in the Tube patients). Patients were followed in person or by telephone over a period of 12-weeks postoperatively. Outcomes were measured at day 7, as well as weeks 4, 8, and 12 weeks. Results: The majority of participants (77% in each group) were male and had coronary artery bypass graft surgery (66% standard sternal precautions and 72% Keep Your Move in the Tube). Univariate analysis revealed the standard sternal precautions group had lesser ability to return to functional activities than the Keep Your Move in the Tube group ( p<0.0001) over time. This difference was minimized however, by week 12. Multivariate analysis revealed that increasing age, body mass index, and female sex were associated with greater functional impairment over time, but no difference between standard sternal precautions and Keep Your Move in the Tube groups. Conclusions: Keep Your Move in the Tube, a novel patient-oriented movement protocol, has potential for cardiac surgery patients to be more confident and comfortable in their recovery.

Introduction Multivessel coronary artery bypass graft (CABG) with bilateral internal thoracic arteries (BITA) has only been uncommon and technically demanding. We describe our experience with BITA only CABGs requiring ≥ 4 anastomoses. Material and Methods The department's database was queried for patients undergoing isolated CABG with ≥ 4 anastomoses. The surgical technique included systematically a right internal thoracic artery (ITA) of left ITA Y graft. The multivariate model included variables with a p < 0.3 at univariate analysis. Results Between January 2006 and December 2009, 251 consecutive patients (71 ± 10 years) (on-pump: 130, off-pump: 121) had CABG with ≥ 4 anastomoses, representing 21% of total isolated CABGs for the same period; all patients received a totally arterial BITA only revascularization. Follow-up was 4.9 ± 1.6 years. Overall and cardiac cumulative survivals were 78 and 92%, respectively, at 5 years. The occurrence of any major postoperative complication was associated with overall and cardiac mortality (odds ratio [OR]: 3.6, 95% confidence interval [CI]: 1.3–9.9 and OR: 5.4, 95% CI: 1.3–21.9, respectively). Major sternal wound complication requiring surgical revision was not associated with impaired glucose control (n = 9; diabetics: 6/82, 7.3%; nondiabetics: 3/169, 1.8%, p = 0.06). Preoperative kidney failure was associated with incomplete revascularization (OR: 6.2; 95% CI: 1.2–33.5), that was unfailingly due to ungraftable right coronary artery targets. Discussion BITA only revascularization was a valuable and safe procedure, with favorable results in terms of morbidity and mortality at a 5 years' follow-up.

Abstract Background Recent experimental evidence shows that sevoflurane can reduce the inflammatory response during cardiac surgery with cardiopulmonary bypass. However, this observation so far has not been assessed in an adequately powered randomized controlled trial. Methods We plan to include one hundred patients undergoing elective coronary artery bypass graft with cardiopulmonary bypass who will be randomized to receive either volatile anesthetics during cardiopulmonary bypass or total intravenous anesthesia. The primary endpoint of the study is to assess the inflammatory response during cardiopulmonary bypass by measuring PMN-elastase serum levels. Secondary endpoints include serum levels of other pro-inflammatory markers (IL-1β, IL-6, IL-8, TNFα), anti-inflammatory cytokines (TGFβ and IL-10), and microRNA expression in peripheral blood to achieve possible epigenetic mechanisms in this process. In addition clinical endpoints such as presence of major complications in the postoperative period and length of hospital and intensive care unit stay will be assessed. Discussion The trial may determine whether adding volatile anesthetic during cardiopulmonary bypass will attenuate the inflammatory response. Trial registration ClinicalTrials.gov NCT02672345.

Background Propofol is increasingly used for cardiac anesthesia and for perioperative sedation. Because pharmacokinetic parameters vary among distinct patient populations, rational drug dosing in the cardiac surgery patient is dependent on characterization of the drug's pharmacokinetic parameters in patients actually undergoing cardiac procedures and cardiopulmonary bypass (CPB). In this study, the pharmacokinetics of propofol was characterized in adult patients undergoing coronary revascularization. Methods Anesthesia was induced and maintained by computer-controlled infusions of propofol and alfentanil, or sufentanil, in 41 adult patients undergoing coronary artery bypass graft surgery. Blood samples for determination of plasma propofol concentrations were collected during the predefined study periods and assayed by high-pressure liquid chromatography. Three-compartment model pharmacokinetic parameters were determined by nonlinear extended least-squares regression of pooled data from patients receiving propofol throughout the perioperative period. The effect of CPB on propofol pharmacokinetics was modeled by allowing the parameters to change with the institution and completion of extracorporeal circulation and selecting the optimal model on the basis of the logarithm of the likelihood. Predicted propofol concentrations were calculated by convolving the infusion rates with unit disposition functions using the estimated parameters. The predictive accuracy of the parameters was evaluated by cross-validation and by a prospective comparison of predicted and measured levels in a subset of patients. Results Optimal pharmacokinetic parameters were: central compartment volume = 6.0 l; second compartment volume = 49.5 l; third compartment volume = 429.3 l; Cl1 (elimination clearance) = 0.68 l/min; Cl2 (distribution clearance) = 1.97 l/min1; and Cl3 (distribution clearance) = 0.70 l/min. The effects of CPB were optimally modeled by step changes in V1 and Cl1 to values of 15.9 and 1.95, respectively, with the institution of CPB. Median absolute prediction error was 18% in the cross-validation assessment and 19% in the prospective evaluation. There was no evidence for nonlinear kinetics. Previously published propofol pharmacokinetic parameter sets poorly predicted the observed concentrations in cardiac surgical patients. Conclusions The pharmacokinetics of propofol in adult patients undergoing cardiac surgery with CPB are dissimilar from those reported for other adult patient populations. The effect of CPB was best modeled by an increase in V1 and Cl1. Predictive accuracy of the derived pharmacokinetic parameters was excellent as measured by cross-validation and a prospective test.

AbstractOnly sparse epidemiological data are available regarding the risk of ischemic stroke (IS) after coronary artery bypass surgery (CABG). Here we aimed to describe the incidence and predictors of IS associated with CABG performed after acute myocardial infarction (AMI), as well as trends over time. We analyzed data for 248,925 unselected AMI patients. We separately analyzed groups of patients who underwent CABG early or late after the index infarction. IS incidence rates per year at risk were 15.8% (95% confidence interval, 14.5–17.1) and 10.9% (10.6–11.2), respectively, among patients with and without CABG in the early cohort, and 4.0% (3.5–4.5) and 2.3% (2.2–2.3), respectively, among patients with and without CABG in the late cohort. Predictors of post-AMI IS included prior IS, CABG, prior atrial fibrillation, prior hemorrhagic stroke, heart failure during hospitalization, older age, diabetes mellitus, and hypertension. Reduced IS risk was associated with use of statins and P2Y12 inhibitors. IS incidence markedly decreased among patients who did not undergo CABG, while no such reduction over time occurred among those who underwent CABG. This emphasizes the need to optimize modifiable risk factors and to consistently use treatments that may reduce IS risk among CABG patients.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Research into major bleeding during cardiac surgery is challenging due to variability in how it is scored. Two consensus-based clinical scores for major bleeding: the Universal definition of perioperative bleeding and the European Coronary Artery Bypass Graft (E-CABG) bleeding severity grade, were compared in this substudy of the Transfusion Avoidance in Cardiac Surgery (TACS) trial. Methods As part of TACS, 7,402 patients underwent cardiac surgery at 12 hospitals from 2014 to 2015. We examined content validity by comparing scored items, construct validity by examining associations with redo and complex procedures, and criterion validity by examining 28-day in-hospital mortality risk across bleeding severity categories. Hierarchical logistic regression models were constructed that incorporated important predictors and categories of bleeding. Results E-CABG and Universal scores were correlated (Spearman ρ = 0.78, P &lt; 0.0001), but E-CABG classified 910 (12.4%) patients as having more severe bleeding, whereas the Universal score classified 1,729 (23.8%) as more severe. Higher E-CABG and Universal scores were observed in redo and complex procedures. Increasing E-CABG and Universal scores were associated with increased mortality in unadjusted and adjusted analyses. Regression model discrimination based on predictors of perioperative mortality increased with additional inclusion of the Universal score (c-statistic increase from 0.83 to 0.91) or E-CABG (c-statistic increase from 0.83 to 0.92). When other major postoperative complications were added to these models, the association between Universal or E-CABG bleeding with mortality remained. Conclusions Although each offers different advantages, both the Universal score and E-CABG performed well in the validity assessments, supporting their use as outcome measures in clinical trials.
