Abstract Background Neutrophil–lymphocyte ratio (NLR) is a valuable indicator for evaluating inflammation and adverse outcomes after cardiac surgery. The objective of this study was to evaluate the association of perioperative NLR with clinical outcomes in infants undergoing congenital heart surgery with cardiopulmonary bypass. Methods We performed a retrospective review of 424 consecutive infants (≤ 1 year) undergoing cardiac surgery between January 2019 and September 2019. Neonates (≤ 28 days) and patients with incomplete NLR data were excluded. The study endpoint was a composite of poor outcomes after surgery. We assess the correlation between perioperative NLR and clinical outcomes. A receiver operating characteristic curve and multivariable logistic regression were applied to identify the prognosis performance of postoperative NLR for poor outcomes. Results A total of 68 (16%) infants experienced at least one of the poor outcomes. Postoperative NLR on the third day after the surgery showed the best prognostic significance (AUC = 0.763, 95%CI 0.700–0.826) among perioperative period, with a cut-off value of 2.05. Postoperative NLR was also strongly correlated with mechanical ventilation time, length of ICU and hospital stay (p < 0.001). Multivariable logistic regression revealed that elevated postoperative NLR (OR 3.722, 95%CI 1.895–7.309, p < 0.001) was an independent risk factor for poor outcomes in infants after cardiac surgery. Conclusions Postoperative NLR was correlated with increased mechanical ventilation time, length of ICU and hospital stay. Elevated postoperative NLR was an independent predictor for poor outcomes after cardiac surgery in infants.

Abstract Abstract Background : The use of dexmedetomidine for sedation post-cardiac surgery is controversial compared to the use of propofol. Methods : A computerized search on Medline, EMBASE, Web of Science, and Agency for Healthcare Research and Quality databases was performed for up to July 2019. Trials evaluating the efficacy of dexmedetomidine versus propofol in the postoperative sedation of cardiac surgery patients were selected. Primary study outcomes were classified as time-dependent (mechanical ventilation time; time to extubation; length of stay in the intensive care unit and the hospital) and non-time dependent (delirium, bradycardia, and hypotension). Results : Our final analysis included 11 RCTs published between 2003 and 2019 and involved a total of 1184 patients. Time to extubation was significantly reduced in the dexmedetomidine group (Standardized Mean Difference (SMD) = -0.61, 95% Confidence Interval (CI): -1.06 to -0.16, p=0.008), however no difference in mechanical ventilation time was observed (SMD= -0.72, 95% CI: -1.60 to 0.15, N.S.). Moreover, the dexmedetomidine group showed a significant reduction in Intensive Care Unit length of stay (SMD= -0.70, 95% CI: -0.98 to -0.42, p=0.0005) this did not translate into a reduced hospital length of stay (SMD= -1.13, 95% CI: -2.43 to 0.16, N.S). For non-time dependent factors: incidence of delirium was unaffected between groups (OR: 0.68, 95% CI: 0.43 to 1.06, N.S.), while the propofol group of patients had higher rates of bradycardia (OR: 3.39, 95% CI: 1.20 to 9.55, p=0.020) and hypotension (OR: 1.68, 95% CI: 1.09 to 2.58, p=0.017). Conclusion : Despite the ICU time advantages afforded by dexmedetomidine over propofol, the former does not contribute to an overall reduction in hospital length of stay or an overall improvement in postoperative outcomes for heart valve surgery and CABG patients. Time-dependent outcomes confounded by several factors including variability in staff, site-protocols, and complication rates between individual surgical cases.

Abstract Purpose: To evaluate the effect of low-dose exogenous surfactant therapy on infants suffering acute respiratory distress syndrome (ARDS) after cardiac surgery. Materials and methods: We conducted a retrospective case-control study of the archive data of infants diagnosed with ARDS after cardiac surgery and admitted to pediatric cardiac surgical intensive care unit (PICU). A case was defined as a patient that received surfactant and standard therapy; a control was defined as a patient that underwent standard therapy. Controls were identified by matching patients based on age(±30d), weight(±3kg), risk adjustment congenital heart surgery-1 (RACHS-1), and initial ratio of partial pressure of oxygen/fraction of inspired oxygen (PaO2/FiO2) (±10). Outcome variables namely oxygenation indices (OI), ventilation index (VI), mechanical ventilation time and PICU time were compared.Results: Forty-four patients, 22 who received surfactant (surfactant group) and 22 who did not (control group) were analyzed. Surfactant group obtained a significant improvement on OI (13.9 vs 5.62; p=0.000) and VI (42.0 vs 22.4; p=0.000) in 6 hours, while control group got no improvement on OI (13.2 vs 11.5; p=0.065) and VI (40.2 vs 36.4; p=0.100). Compared with control group, surfactant group had shorter ventilation time (133.6h vs 218.4h; p=0.000) and PICU time (10.7d vs 17.5d; p=0.001). Infants in surfactant group under 3 months benefit more from OI and VI than infants over 3 months.Conclusions: In congenital heart disease infants with post-surgery ARDS, low-dose exogenous surfactant treatment could prominently improve oxygenation and reduced mechanical ventilation time and PICU time. And the improvement of oxygenation is more effective for infants under 3 months.

Abstract BackgroundPerioperative diabetes insipidus (DI) is a serious complication occurring in patients undergoing off-pump coronary artery bypass grafting (OPCABG). MethodsThis was a retrospective study of 199 patients who underwent OPCABG surgery in Anzhen hospital, Beijing, China, between January 2019 to December 2019. Patients were divided into a DI(+) group and a DI(-) group according to perioperative urine condition. The incidence of perioperative DI in patients undergoing OPCABG surgery was calculated as the main outcome. Multivariable binary logistic regression analysis was used to identify independent prognostic factors of DI.ResultsPerioperative DI occurred in 43.2% (86/199) of these patients. Mean patient age was 62.5 ± 9.0 years, and 156 (78.4%) were male. Multivariable logistic regression analysis showed a correlation between BMI(OR=0.772, 95%CI[0.670-0.890], P＜0.001), Crystal quantity(OR=1.001, 95%CI[1.000-1.001], P=0.008), perioperative Cr(OR=0.965, 95%CI[0.937-0.993], P=0.016). The DI(+) group had a significantly higher imbalance postoperative PH condition(41.9% vs 28.3%, P<0.05), higher median mechanical ventilation time than the DI(-) group (22.0 vs. 20.5, P<0.01) and higher median of ICU stay hours(27.0 vs 31.0, P=0.041).ConclusionCoronary artery disease(CAD) patients underwent OPCABG surgery were easy to have perioperative DI, which had a higher ICU stay and mechanical ventilation time than those without DI. BMI, Crystal quantity, perioperative creatinine was associated with the presence of DI. Prospective studies are needed to validate these findings.

Abstract Introduction: Patients submitted to cardiovascular surgery present motor and respiratory complications mainly due to high surgery manipulation and the use of mechanical ventilation. Reducing the weaning start time and disconnecting patient's ventilation system prematurely can decrease the pulmonary complications and hospitalization time. Motor complications are the most relevant as they have a direct effect on functional independence provoked by immobility time. Objectives : Identify if mechanical ventilation time has an impact on functional capacity on patients submitted to cardiac surgery in order to contribute to the establishment of reliable evidence to practice through this patient's profile. Materials and methods : Original articles were analyzed, published between 2000 and 2014, which focused on the influence of mechanical ventilation time concerning the functional independence on patients submitted to cardiac surgery, contained in the following electronic database: Scielo, BIREME (LILACS), PubMed e CAPES. Results : It was observed that the length of stay in the intensive care unit in cardiac surgery was influenced directly by CPB, VM and pulmonary dysfunction. Functional independence was compromised in patients with longer duration of mechanical ventilation, postoperative pain and prolonged bed rest. It was also found that there is no consensus on the protocol for improved functional capacity. Conclusion : There is a functional decline in patients undergoing cardiac surgery, especially those at increased length of stay in mechanical ventilation, reflecting a direct and negative impact on their functional independence and quality of life.

Background The transfusion of erythrocytes that have been stored for long periods of time can produce visceral ischemia and favor the acquisition of postsurgical infections. To estimate the role of the duration of storage of erythrocytes on morbidity in cardiac surgery, we performed an observational study. Methods All patients (n = 897) undergoing cardiac surgery during three consecutive years were included. Morbidity (main outcome measure) was evaluated by means of four surrogate measures: duration of stay in the intensive care unit longer than 4 days, mechanical ventilation time longer than 1 day, perioperative myocardial infarction rate, and severe postoperative infection rate. The mean duration of storage of all erythrocytes transfused and the duration of storage of the oldest unit transfused were used as storage variables. Results After considering multiple confounding variables related to patient severity, illness, and surgical difficulty, the duration of storage of erythrocytes was found to be associated neither with a more prolonged stay in the intensive care unit or mechanical ventilation time nor with increased rates of perioperative infarction, mediastinitis, or sepsis. However, each day of storage of the oldest unit was associated with an increment of the risk of pneumonia of 6% (95% confidence interval, 1-11; P = 0.018). The cutoff point of maximum sensitivity and specificity (54.8 and 66.9%) associated with a greater risk for pneumonia corresponded to 28 days of storage for the oldest unit (odds ratio, 2.74; 95% confidence interval, 1.18-6.36; P = 0.019). Conclusions Prolonged storage of erythrocytes does not increase morbidity in cardiac surgery. However, storage for longer than 28 days could be a risk factor for the acquisition of nosocomial pneumonia.

Abstract BACKGROUND: The efficacy and safety of dexmedetomidine in sedation for postoperative cardiac surgeries is controversial when compared to propofol. METHODS: A computerized search of Medline, Cochrane and Google Scholar databases was performed through August 2018. Studies evaluating the efficacy of dexmedetomidine versus propofol in the sedation of postoperative cardiac surgery patients were searched. The main study outcomes were divided into time dependent (mechanical ventilation time; time to extubation; length of stay in the intensive care unit and in the hospital) and non-time dependent (delirium, bradycardia, and hypotension). RESULTS: The final analysis included 15 trials with a total of 2488 patients. Time to extubation was significantly reduced in the dexmedetomidine group (Standardized Mean Difference (SMD) = -0.54, 95% Confidence Interval (CI): -0.89 to -0.18, p=0.003), as well as mechanical ventilation time (SMD= -0.71, 95% CI: -1.19 to -0.23, p=0.004). Moreover, the dexmedetomidine group showed a significant reduction in Intensive Care Unit length of stay (SMD= -0.38, 95% CI: -0.60 to -0.16, p=0.001) and hospital length of stay (SMD= -0.39, 95% CI: -0.60 to -0.19, p<0.001). However, these time dependent outcomes could have been affected by several confounding factors, thus limiting the value of these results. Incidence of delirium was reduced in the dexmedetomidine group (OR: 0.47, 95% CI: 0.29 to 0.76, p=0.002), while this group of patients had higher rates of bradycardia (OR: 2.52, 95% CI: 1.15 to 5.55, p=0.021). There was no significant difference in rates of hypotension between the two groups. CONCLUSION: Despite the apparent time advantages afforded by dexmedetomidine over propofol, the former does not show particular overall improvements in postoperative care of cardiac surgery patients. Since time dependent outcomes seems to be affected by several confounding factors, more efforts are needed to analyze factors that could affect sedation in post-cardiac surgery patients and choose unbiased outcomes.

AbstractObjectiveThe aim of the present study was to explore and compare the association between a new vasoactive score – the Total Inotrope Exposure Score – and outcome and the established Vasoactive Inotrope Score in children undergoing cardiac surgery with cardiopulmonary bypassDesignThe present study was a single-centre, retrospective study.SettingThe study was carried out at a 21-bed cardiovascular ICU in a Tertiary Children’s Hospital between September, 2010 and May, 2011MethodsThe Total Inotrope Exposure Score is a new vasoactive score that brings together cumulative vasoactive drug exposure and incorporates dose adjustments over time. The performance of these scores – average, maximum Vasoactive Inotrope Score at 24 and 48 hours, and Total Inotrope Exposure Score – to predict primary clinical outcomes – either death, cardiopulmonary resuscitation, or extra-corporeal membrane oxygenation before hospital discharge – and secondary outcomes – length of invasive mechanical ventilation, length of ICU stay, and hospital stay – was calculated.Main resultsThe study cohort included 167 children under 18 years of age, with 37 (22.2%) neonates and 65 (41.3%) infants aged between 1 month and 1 year. The Total Inotrope Exposure Score best predicted the primary outcome (six of 167 cases) with an unadjusted odds ratio for a poor outcome of 42 (4.8, 369.6). Although the area under curve was higher than other scores, this difference did not reach statistical significance. The Total Inotrope Exposure Score best predicted prolonged invasive mechanical ventilation, length of ICU stay, and hospital stay as compared with the other scores.ConclusionThe Total Inotrope Exposure Score appears to have a good association with poor postoperative outcomes and warrants prospective validation across larger numbers of patients across institutions.
