ABSTRACT We sought to establish the efficacy and safety of prophylactic steroids in adult patients undergoing cardiopulmonary bypass (CPB). We performed a meta-analysis of randomized trials reporting the effects of prophylactic steroids on clinical outcomes after CPB. Outcomes examined were mortality, myocardial infarction, neurological events, new onset atrial fibrillation, transfusion requirements, postoperative bleeding, duration of ventilation, intensive care unit (ICU) stay, hospital stay, wound complications, gastrointestinal complications, and infectious complications. We included 44 trials randomizing 3205 patients. Steroids reduced new onset atrial fibrillation [relative risk (RR) 0.71, 95% confidence interval (CI) 0.59 to 0.87], postoperative bleeding [weighted mean difference (WMD) -99.6 mL, 95% CI -149.8 to -49.3], and duration of ICU stay (WMD -0.23 days, 95% CI -0.40 to -0.07). Length of hospital stay was also reduced (WMD -0.59 days, 95% CI -1.17 to -0.02), but this result was less robust. A trend towards reduction in mortality was observed (RR 0.73, 95% CI 0.45 to 1.18). Randomized trials suggest that perioperative steroids have significant clinical benefit in CPB patients by decreasing the risk of new onset atrial fibrillation, while results are encouraging for reducing bleeding, length of stay, and mortality. These data do not raise major safety concerns, however, a sufficiently powered trial is warranted to confirm or refute these findings.

    • "Ulinastatin also significantly decreased the postoperative levels of cTnI. Normally, it has been shown that surgical procedures as well as CPB during cardiac surgery induce a systemic acute inflammatory response and regional myocardial I/R injury leading to increased endothelial permeability and free radical damage to vessels and parenchyma with coincident myocardial damage [63]. Both cTnI and CK-MB are predictive factors which reflect myocardial injury where cTnI is the most sensitive indicator of minor myocardial damage with superior cardiac specificity when compared with CK-MB [64] [65] [66].

    ABSTRACT: Introduction. The systematic meta-analysis of randomized controlled trials (RCTs) evaluated the effects of intraoperative ulinastatin on early-postoperative recovery in patients undergoing cardiac surgery. Methods. RCTs comparing intraoperative ulinastatin with placebo in cardiac surgery were searched through PubMed, Cochrane databases, Medline, SinoMed, and the China National Knowledge Infrastructure (1966 to May 20th, 2013). The primary endpoints included hospital mortality, postoperative complication rate, length of stay in intensive care unit, and extubation time. The physiological and biochemical parameters illustrating postoperative cardiac and pulmonary function as well as inflammation response were considered as secondary endpoints. Results. Fifteen RCTs (509 patients) met the inclusion criteria. Ulinastatin did not affect hospital mortality, postoperative complication rate, or ICU length of stay but reduced extubation time. Ulinastatin also increased the oxygenation index on postoperative day 1 and reduced the plasma level of cardiac troponin-I. Additionally, ulinastatin inhibited the increased level of tumor necrosis factor-alpha, polymorphonuclear neutrophil elastase, interleukin-6, and interleukin-8 associated with cardiac surgery. Conclusion. Ulinastatin may be of value for the inhibition of postoperative increased inflammatory agents and most likely provided pulmonary protective effects in cardiac surgery. However, larger adequately powered RCTs are required to define the clinical effect of ulinastatin on postoperative outcomes in cardiac surgery.

    • "Indeed, the non-physiological perfusion during CPB and the blood contact with the non-endothelial synthetic surfaces of the CPB equipment activates the coagulation cascade, alters the vascular endothelial layer, and promotes the expression of leukocyte adhesion molecules, which may lead to post-bypass end-organ damage [1]. Approaches focused on manipulating the inflammatory process associated with CPB include corticosteroids, miniaturized CPB, or specific inhibition of inflammatory mediators [2] [3] [4]. "

    ABSTRACT: BACKGROUND: Perioperative administration of enoximone has been shown to improve hemodynamics, organ function, and inflammatory response. Aim of the present study is to evaluate the impact of enoximone on postoperative renal function after on-pump cardiac surgery. METHODS: A total of 3727 patients undergoing cardiac surgery at one Institution between May 2004 and November 2010 were reviewed. A propensity score was built and a 1:1 perfect matching was performed, providing two fairly comparable cohorts of 712 patients each, receiving or not enoximone after surgery. Renal function was evaluated by lower glomerular filtration rate (GFR) value reached postoperatively. RESULTS: Overall 30-day mortality rate was 4.3% (62/1424). Cumulative incidence of postoperative renal failure (RF) was 157/1424(11%), of which 99/1424(7%) needed renal replacement therapy. Mean lower postoperative GFR in patients who received or not enoximone was 63±30.1 and 53.5±26.1ml/min/1.73m(2) (p<0.0001), respectively. At multivariable analysis age (OR2.75, p=0.0004), diabetes (OR1.82, p=0.006), preoperative GFR (OR3.81, p<0.0001), preoperative cardiogenic shock (OR1.65, p=0.004), previous cardiac surgery (OR2.12, p=0.0002), type of intervention (OR1.96, p=0.005), and enoximone (OR0.38, p=0.001) were found to be independently associated with postoperative RF. Logistic regression analysis showed that the administration of enoximone (OR0.41, p=0.0001), and of no inotropes (OR0.27, p<0.0001) were protective vs. the occurrence of postoperative RF. CONCLUSION: Patients perioperatively receiving enoximone showed a statistically significant better renal function after cardiac surgery.

    • "Steroid prophylaxis during CPB on inflammation and clinical postoperative recovery has been investigated in different studies with opposite results, that is, beneficial versus irrelevant effects. These discrepancies may be related to the age of patients enrolled in these studies and to dosage, timing and the type of steroid administered [3] [4] [5] [6] [7] [8] [9]. PTX3 was found to be increased also in control patients not receiving dexamethasone. "

    ABSTRACT: Glucocorticoid administration before cardiopulmonary bypass (CPB) can reduce the systemic inflammatory response and improve clinical outcome. Long pentraxin PTX3 is a novel inflammatory parameter that could play a protective cardiovascular role by regulating inflammation. Twenty-nine children undergoing open heart surgery were enrolled in the study. Fourteen received dexamethasone (1st dose 1.5  mg/Kg i.v. or i.m. the evening before surgery; 2nd dose 1.5  mg/kg i.v. before starting bypass) and fifteen children served as control. Blood PTX3, short pentraxin C-reactive protein (CRP), interleukin-1 receptor II (IL-1RII), fibrinogen and partial thromboplastin time (PTT) were assayed at different times. PTX3 levels significantly increased during CPB in dexamethasone-treated (+D) and dexamethasone-untreated (-D) subjects, but were significantly higher in +D than -D patients. CRP levels significantly increased both in +D and -D patients in the postoperative days, with values significantly higher in -D than +D patients. Fibrinogen and PTT values were significantly higher in -D than +D patients in the 1st postoperative day. IL-1RII plasma levels increased in the postoperative period in both groups. Dexamethasone prophylaxis in pediatric patients undergoing CPB for cardiac surgery is associated with a significant increase of blood PTX3 that could contribute to decreasing inflammatory parameters and improving patient clinical outcome.
