Two studies assessed initiatives to improve the quality and the cost-effectiveness of cardiac surgery. The first evaluated a system for access and stabilization (SAS), with coronary stabilization, and a clinical effectiveness quality initiative (CEQI) in off-pump coronary artery bypass grafting. The SAS + CEQI cohort showed significantly lower mortality, a lower percentage of patients requiring prolonged ventilation, and a shorter mean postoperative length of hospital stay than the pre-SAS cohort who underwent on-pump coronary artery bypass grafting. The second study assessed the potential for noninvasive cerebral oximetry to reduce strokes related to all cardiac surgery by optimizing cerebral oxygen delivery. The incidence of permanent stroke was significantly lower in the cerebral oximetry group than in an earlier control group in which cerebral oximetry was not used, despite the fact that the study group had a significantly greater number of patients in New York Heart Association classes III and IV. The proportion of patients requiring prolonged ventilation was significantly lower, and the length of postoperative hospital stay was significantly shorter in the study group than in the control group. The incidence of cerebrovascular accident in the study group was 0.97%, compared with 2.03% in the controls. This translated to a potential avoidance of 12 cerebrovascular accidents and approximately $254 214 in direct costs and more than $425000 in total costs. The results show that specific measures can improve outcomes and reduce costs in cardiac surgery. Therefore, the use of a clinical effectiveness quality initiative and cerebral oximetry in all cardiac surgery, with the SAS system for off-pump surgery, should be advocated.

Abstract Background Cerebral oximetry has been widely used to measure regional oxygen saturation in brain tissue, especially during cardiac surgery. Despite its popularity, there have been inconsistent results on the use of cerebral oximetry during cardiac surgery, and few studies have evaluated cerebral oximetry during off pump coronary artery bypass graft surgery (OPCAB). Methods To evaluate the relationship between intraoperative cerebral oximetry and postoperative delirium in patients who underwent OPCAB, we included 1439 patients who underwent OPCAB between October 2004 and December 2016 and among them, 815 patients with sufficient data on regional cerebral oxygen saturation (rSO2) were enrolled in this study. We retrospectively analyzed perioperative variables and the reduction in rSO2 below cut-off values of 75, 70, 65, 60, 55, 50, 45, 40, and 35%. Furthermore, we evaluated the relationship between the reduction in rSO2 and postoperative delirium. Results Delirium occurred in 105 of 815 patients. In both univariable and multivariable analyses, the duration of rSO2 reduction was significantly longer in patients with delirium at cut-offs of < 50 and 45% (for every 5 min, adjusted odds ratio (OR) 1.007 [95% Confidence interval (CI) 1.001 to 1.014] and adjusted OR 1.012 [1.003 to 1.021]; p = 0.024 and 0.011, respectively). The proportion of patients with a rSO2 reduction < 45% was significantly higher among those with delirium (adjusted OR 1.737[1.064 to 2.836], p = 0.027). Conclusions In patients undergoing OPCAB, intraoperative rSO2 reduction was associated with postoperative delirium. Duration of rSO2 less than 50% was 40% longer in the patients with postoperative delirium. The cut-off value of intraoperative rSO2 that associated with postoperative delirium was 50% for the total patient population and 55% for the patients younger than 68 years.

Background: An intra-aortic balloon pump (IABP) is the most commonly used circulatory assist device in cardiac surgery. We hypothesized that prophylactic application of an IABP improves early clinical outcome of high-risk patients undergoing scheduled off-pump coronary artery bypass grafting (OPCABG). Methods: From January 2010 to December 2013, hemodynamically stable, high-risk patients undergoing scheduled OPCABG with preincision use of an IABP were recruited to the IABP group. Using the propensity score-matching method, every patient in the IABP group was matched with another patient (the control group) with a similar propensity score who received an IABP on an as-needed basis during or after OPCABG. Surgical mortality and major morbidity rates were compared between groups. Results: A total of 116 patient pairs were included in this study. In patients in the IABP group, postoperative low cardiac output and respiratory as well as renal failure were less frequent, intensive care unit stay was shorter, and surgical mortality was lower compared to patients in the control group. In multivariate logistic regression, timing of IABP implantation, as an independent risk factor, was associated with postoperative low cardiac output (OR = 2.02, 95% CI 1.28-5.76), respiratory failure (OR = 1.86, 95% CI 1.19-4.27), renal failure (OR = 2.96, 95% CI 1.51-6.63) and surgical mortality (OR = 2.45, 95% CI 1.42-6.07). Conclusions: Prophylactic application of an IABP improves postoperative cardiac performance, reduces respiratory and renal complications, and consequently lowers surgical mortality in high-risk patients undergoing scheduled OPCABG.

Background: Intensive post-operative physiotherapy after cardiac surgery helps to reduce the number of complications, accelerating convalescence and decreasing peri-operative mortality. Cardiac rehabilitation is aimed at regaining lost function and sustaining the effect of cardiac surgery. The aim of this study was to compare the efficacy of inpatient and home-based phase II physiotherapy following coronary artery bypass grafting, and inpatient phase II post-operative physiotherapy based on the analysis of the spirometry results. Methods: A prospective observational study included 104 adult patients of both sexes undergoing planned coronary artery bypass grafting and were randomized to one of the two groups—inpatients (InPhysio) and home-based (HomePhysio) at a 1:1 ratio. All patients had undergone spirometry testing prior to surgery (S1) and on the fifth day after the operation (S2), i.e., on the day of completion of the first phase (PI) of physiotherapy. Both the study group (InPhysio) and the control group (HomePhysio) performed the same set of exercises in the second phase (PII) of cardiac physiotherapy, either in the hospital or at home, respectively, according to the program obtained in the hospital. Both groups have undergone spirometry testing (S3) at 30 days after the operation. Results: The demographic and peri-operative data for both groups were comparable and showed no statistically significant differences. An analysis of gradients between the results of spirometry tests before surgery and at 30 days after the surgery showed a smaller decrease in forced vital capacity (FVC) in the study group than in the control group (p < 0.001). The results at five and 30 days after the surgery showed a greater increase in FVC in the study group than in the control group (680 mL vs. 450 mL, p = 0.009). There were no statistically significant differences in other parameters studied. Conclusions: The advantage of inpatient over home-based physiotherapy was evidenced by much smaller decreases in FVC between the initial and final tests, and greater increases between the fifth day after surgery and the final test. Our analysis showed greater efficacy of inpatient physiotherapy as compared with home-based exercises and raises concerns about patient adherence.
