    (2015) HAJJAR, Ludhmila Abrahao; FUKUSHIMA, Julia Tizue; ALMEIDA, Juliano Pinheiro de; OSAWA, Eduardo Atsushi; GALAS, Filomena Regina Barbosa Gomes
    Purpose of review Anemia has been demonstrated to be detrimental in several populations such as high-surgical-risk patients, critically ill elderly, and cardiac patients. Red blood cell transfusion is the most commonly prescribed therapy for anemia. Despite being life-saving, it carries a risk that ranges from mild complications to death. The aim of this review is to discuss the risks of anemia and blood transfusion, and to describe recent developments in the strategies to reduce allogeneic blood transfusion. Recent findings In the past decades, clinical studies comparing transfusion strategies in different populations were conducted. Despite the challenges imposed by the development of such studies, evidence-based medicine on transfusion medicine in critically ill patients is being created. Different results arising from these studies reflect population heterogeneity, specific circumstances, and difficulties in measuring the impact of anemia and transfusion in a clinical trial. Summary An adequate judgment of a clinical condition associated with proper application of the available literature is the cornerstone in the management of transfusion in critical care. Apart from this individualized strategy, the institution of a patient blood management program allows goal-directed approach through preoperative recognition of anemia, surgical efforts to minimize blood loss, and continuous assessment of the coagulation status.

    Diaphragmatic pacing stimulation in spinal cord injury: anesthetic and perioperative management
    (2012) TEDDE, Miguel L.; VASCONCELOS FILHO, Paulo; HAJJAR, Ludhmila Abrahao; ALMEIDA, Juliano Pinheiro de; FLORA, Gustavo Fagundes; OKUMURA, Erica Mie; OSAWA, Eduardo A.; FUKUSHIMA, Julia Tizue; TEIXEIRA, Manoel Jacobsen; GALAS, Filomena Regina Barbosa Gomes; JATENE, Fabio Biscegli; AULER JR., Jose Otavio Costa
    OBJECTIVE: The standard therapy for patients with high-level spinal cord injury is long-term mechanical ventilation through a tracheostomy. However, in some cases, this approach results in death or disability. The aim of this study is to highlight the anesthetics and perioperative aspects of patients undergoing insertion of a diaphragmatic pacemaker. METHODS: Five patients with quadriplegia following high cervical traumatic spinal cord injury and ventilator-dependent chronic respiratory failure were implanted with a laparoscopic diaphragmatic pacemaker after preoperative assessments of their phrenic nerve function and diaphragm contractility through transcutaneous nerve stimulation. ClinicalTrials.gov:NCT01385384. RESULTS: The diaphragmatic pacemaker placement was successful in all of the patients. Two patients presented with capnothorax during the perioperative period, which resolved without consequences. After six months, three patients achieved continuous use of the diaphragm pacing system, and one patient could be removed from mechanical ventilation for more than 4 hours per day. CONCLUSIONS: The implantation of a diaphragmatic phrenic system is a new and safe technique with potential to improve the quality of life of patients who are dependent on mechanical ventilation because of spinal cord injuries. Appropriate indication and adequate perioperative care are fundamental to achieving better results.

    (2018) SARDO, Salvatore; OSAWA, Eduardo Atsushi; FINCO, Gabriele; GALAS, Filomena Regina Barbosa Gomes; ALMEIDA, Juliano Pinheiro de; CUTULI, Salvatore Lucio; FRASSANITO, Claudia; LANDONI, Giovanni; HAJJAR, Ludhmila Abrahao
    Objectives: To investigate the efficacy and safety of perioperative administration of nitric oxide in cardiac surgery. Design: Meta-analysis of randomized controlled trials (RCTs). Participants: Cardiac surgery patients. Interventions: A search of Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and MEDLINE for RCTs that compared nitric oxide with placebo or other comparators. Measurements and Main Results: The primary outcome was intensive care unit (ICU) stay, and secondary outcomes were mortality, duration of mechanical ventilation, and reduction of mean pulmonary artery pressure. The study included 18 RCTs comprising 958 patients. The authors calculated the pooled odds ratio (OR) and the mean difference (MD) with random-effects model. Quantitative synthesis of data demonstrated a clinically negligible reduction in the length of ICU stay (MD -0.38 days, confidence interval CI [-0.65 to -0.11]; p = 0.005) and mechanical ventilation duration (MD -4.81 hours, CI [-7.79 to -1.83]; p = 0.002) compared with all control interventions with no benefit on mortality. Conclusions: Perioperative delivery of inhaled nitric oxide resulted to be of no or minimal benefit in patients with pulmonary hypertension undergoing cardiac surgery. Large, randomized trials are needed to further assess its effect on major clinical outcomes and its cost-effectiveness.

    (2017) LEME, Alcino Costa; HAJJAR, Ludhmila Abrahao; VOLPE, Marcia S.; FUKUSHIMA, Julia Tizue; SANTIAGO, Roberta Ribeiro De Santis; OSAWA, Eduardo A.; ALMEIDA, Juliano Pinheiro de; GERENT, Aline Muller; FRANCO, Rafael Alves; FELTRIM, Maria Ignez Zanetti; NOZAWA, Emilia; COIMBRA, Vera Regina de Moraes; IANOTTI, Rafael de Moraes; HASHIZUME, Clarice Shiguemi; KALIL FILHO, Roberto; AULER JR., Jose Otavio Costa; JATENE, Fabio Biscegli; GALAS, Filomena Regina Barbosa Gomes; AMATO, Marcelo Britto Passos
    IMPORTANCE Perioperative lung-protective ventilation has been recommended to reduce pulmonary complications after cardiac surgery. The protective role of a small tidal volume (VT) has been established, whereas the added protection afforded by alveolar recruiting strategies remains controversial. OBJECTIVE To determine whether an intensive alveolar recruitment strategy could reduce postoperative pulmonary complications, when added to a protective ventilation with small VT. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of patients with hypoxemia after cardiac surgery at a single ICU in Brazil (December 2011-2014). INTERVENTIONS Intensive recruitment strategy (n=157) or moderate recruitment strategy (n=163) plus protective ventilation with small VT. MAIN OUTCOMES AND MEASURES Severity of postoperative pulmonary complications computed until hospital discharge, analyzed with a common odds ratio (OR) to detect ordinal shift in distribution of pulmonary complication severity score (0-to-5 scale, 0, no complications; 5, death). Prespecified secondary outcomes were length of stay in the ICU and hospital, incidence of barotrauma, and hospital mortality. RESULTS All 320 patients (median age, 62 years; IQR, 56-69 years; 125 women [39%]) completed the trial. The intensive recruitment strategy group had a mean 1.8 (95% CI, 1.7 to 2.0) and a median 1.7 (IQR, 1.0-2.0) pulmonary complications score vs 2.1 (95% CI, 2.0-2.3) and 2.0 (IQR, 1.5-3.0) for the moderate strategy group. Overall, the distribution of primary outcome scores shifted consistently in favor of the intensive strategy, with a common OR for lower scores of 1.86 (95% CI, 1.22 to 2.83; P =.003). The mean hospital stay for the moderate group was 12.4 days vs 10.9 days in the intensive group (absolute difference, -1.5 days; 95% CI, -3.1 to -0.3; P =.04). The mean ICU stay for the moderate group was 4.8 days vs 3.8 days for the intensive group (absolute difference, -1.0 days; 95% CI, -1.6 to -0.2; P =.01). Hospital mortality (2.5% in the intensive group vs 4.9% in the moderate group; absolute difference, -2.4%, 95% CI, -7.1% to 2.2%) and barotrauma incidence (0% in the intensive group vs 0.6% in the moderate group; absolute difference, -0.6%; 95% CI, -1.8% to 0.6%; P =.51) did not differ significantly between groups. CONCLUSIONS AND RELEVANCE Among patients with hypoxemia after cardiac surgery, the use of an intensive vs a moderate alveolar recruitment strategy resulted in less severe pulmonary complications while in the hospital.

    A liberal strategy of red blood cell transfusion reduces cardiogenic shock in elderly patients undergoing cardiac surgery
    (2015) NAKAMURA, Rosana Ely; VINCENT, Jean-Louis; FUKUSHIMA, Julia Tizue; ALMEIDA, Juliano Pinheiro de; FRANCO, Rafael Alves; PARK, Clarice Lee; OSAWA, Eduardo Atsushi; SILVA, Carolina Maria Pinto; AULER JR., Jose Otavio Costa; LANDONI, Giovanni; GALAS, Filomena Regina Barbosa Gomes; KALIL FILHO, Roberto; HAJJAR, Ludhmila Abrahao
    Objective: The aim of this study was to compare outcomes in patients undergoing cardiac surgery who are aged 60 years or more or less than 60 years after implementation of a restrictive or a liberal transfusion strategy. Methods: This is a substudy of the Transfusion Requirements After Cardiac Surgery (TRACS) randomized controlled trial. In this subgroup analysis, we separated patients into those aged 60 years or more (elderly) and those aged less than 60 years randomized to a restrictive or a liberal strategy of red blood cell transfusion. The primary outcome was a composite defined as a combination of 30-day all-cause mortality and severe morbidity. Results: Of the 502 patients included in the Transfusion Requirements After Cardiac Surgery study, 260 (51.8%) were aged 60 years or more and 242 (48.2%) were aged less than 60 years and were included in this study. The primary end point occurred in 11.9% of patients in the liberal strategy group and 16.8% of patients in the restrictive strategy group (P = .254) for those aged 60 years or more and in 6.8% of patients in the liberal strategy group and 5.6% of patients in the restrictive strategy group for those aged less than 60 years (P = .714). However, in the older patients, cardiogenic shock was more frequent in patients in the restrictive transfusion group (12.8% vs 5.2%, P = .031). Thirty-day mortality, acute respiratory distress syndrome, and acute renal injury were similar in the restrictive and liberal transfusion groups in both age groups. Conclusions: Although there was no difference between groups regarding the primary outcome, a restrictive transfusion strategy may result in an increased rate of cardiogenic shock in elderly patients undergoing cardiac surgery compared with a more liberal strategy. Cardiovascular risk of anemia may be more harmful than the risk of blood transfusion in older patients.

    Background: Several studies have indicated that a restrictive erythrocyte transfusion strategy is as safe as a liberal one in critically ill patients, but there is no clear evidence to support the superiority of any perioperative transfusion strategy in patients with cancer. Methods: In a randomized, controlled, parallel-group, double-blind (patients and outcome assessors) superiority trial in the intensive care unit of a tertiary oncology hospital, the authors evaluated whether a restrictive strategy of erythrocyte transfusion (transfusion when hemoglobin concentration <7 g/dl) was superior to a liberal one (transfusion when hemoglobin concentration <9 g/dl) for reducing mortality and severe clinical complications among patients having major cancer surgery. All adult patients with cancer having major abdominal surgery who required postoperative intensive care were included and randomly allocated to treatment with the liberal or the restrictive erythrocyte transfusion strategy. The primary outcome was a composite endpoint of mortality and morbidity. Results: A total of 198 patients were included as follows: 101 in the restrictive group and 97 in the liberal group. The primary composite endpoint occurred in 19.6% (95% CI, 12.9 to 28.6%) of patients in the liberal-strategy group and in 35.6% (27.0 to 45.4%) of patients in the restrictive-strategy group (P = 0.012). Compared with the restrictive strategy, the liberal transfusion strategy was associated with an absolute risk reduction for the composite outcome of 16% (3.8 to 28.2%) and a number needed to treat of 6.2 (3.5 to 26.5). Conclusion: A liberal erythrocyte transfusion strategy with a hemoglobin trigger of 9 g/dl was associated with fewer major postoperative complications in patients having major cancer surgery compared with a restrictive strategy.

    High levels of B-type natriuretic peptide predict weaning failure from mechanical ventilation in adult patients after cardiac surgery
    (2013) LARA, Thiago Martins; HAJJAR, Ludhmila Abrahao; ALMEIDA, Juliano Pinheiro de; FUKUSHIMA, Julia Tizue; BARBAS, Carmem Silvia Valente; RODRIGUES, Adriano Rogerio Baldacin; NOZAWA, Emilia; FELTRIM, Maria Ignes Zanetti; ALMEIDA, Elisangela; COIMBRA, Vera; OSAWA, Eduardo; IANOTTI, Rafael de Moraes; LEME, Alcino Costa; JATENE, Fabio Biscegli; AULER- JR., Jose Otavio Costa; GALAS, Filomena Regina Barbosa Gomes
    OBJECTIVE: The failure to wean from mechanical ventilation is related to worse outcomes after cardiac surgery. The aim of this study was to evaluate whether the serum level of B-type natriuretic peptide is a predictor of weaning failure from mechanical ventilation after cardiac surgery. METHODS: We conducted a prospective, observational cohort study of 101 patients who underwent on-pump coronary artery bypass grafting. B-type natriuretic peptide was measured postoperatively after intensive care unit admission and at the end of a 60-min spontaneous breathing test. The demographic data, hemodynamic and respiratory parameters, fluid balance, need for vasopressor or inotropic support, and length of the intensive care unit and hospital stays were recorded. Weaning failure was considered as either the inability to sustain spontaneous breathing after 60 min or the need for reintubation within 48 h. RESULTS: Of the 101 patients studied, 12 patients failed the weaning trial. There were no differences between the groups in the baseline or intraoperative characteristics, including left ventricular function, EuroSCORE and lengths of the cardiac procedure and cardiopulmonary bypass. The B-type natriuretic peptide levels were significantly higher at intensive care unit admission and at the end of the breathing test in the patients with weaning failure compared with the patients who were successfully weaned. In a multivariate model, a high B-type natriuretic peptide level at the end of a spontaneous breathing trial was the only independent predictor of weaning failure from mechanical ventilation. CONCLUSIONS: A high B-type natriuretic peptide level is a predictive factor for the failure to wean from mechanical ventilation after cardiac surgery. These findings suggest that optimizing ventricular function should be a goal during the perioperative period.

    Vasopressin versus Norepinephrine in Patients with Vasoplegic Shock after Cardiac Surgery The VANCS Randomized Controlled Trial
    (2017) HAJJAR, Ludhmila Abrahao; VINCENT, Jean Louis; GALAS, Filomena Regina Barbosa Gomes; RHODES, Andrew; LANDONI, Giovanni; OSAWA, Eduardo Atsushi; MELO, Renato Rosa; SUNDIN, Marcia Rodrigues; GRANDE, Solimar Miranda; GAIOTTO, Fabio A.; POMERANTZEFF, Pablo Maria; DALLAN, Luis Oliveira; FRANCO, Rafael Alves; NAKAMURA, Rosana Ely; LISBOA, Luiz Augusto; ALMEDIA, Juliano Pinheiro de; GERENT, Aline Muller; SOUZA, Dayenne Hianae; GAIANE, Maria Alice; FUKUSHIMA, Julia Tizue; PARK, Clarice Lee; ZAMBOLIM, Cristiane; FERREIRA, Graziela Santos Rocha; STRABELLI, Tania Mara; FERNANDES, Felipe Lourenco; CAMARA, Ligia; ZEFERINO, Suely; SANTOS, Valter Garcia; PICCIONI, Marilde Albuquerque; JATENE, Fabio Biscegli; AULER JR., Jose Otavio Costa; KALIL FILHO, Roberto
    Background: Vasoplegic syndrome is a common complication after cardiac surgery and impacts negatively on patient outcomes. The objective of this study was to evaluate whether vasopressin is superior to norepinephrine in reducing postoperative complications in patients with vasoplegic syndrome. Methods: This prospective, randomized, double-blind trial was conducted at the Heart Institute, University of Sao Paulo, Sao Paulo, Brazil, between January 2012 and March 2014. Patients with vasoplegic shock (defined as mean arterial pressure less than 65 mmHg resistant to fluid challenge and cardiac index greater than 2.2 l.min(-1).m(-2)) after cardiac surgery were randomized to receive vasopressin (0.01 to 0.06 U/min) or norepinephrine (10 to 60 mu g/min) to maintain arterial pressure. The primary endpoint was a composite of mortality or severe complications (stroke, requirement for mechanical ventilation for longer than 48 h, deep sternal wound infection, reoperation, or acute renal failure) within 30 days. Results: A total of 330 patients were randomized, and 300 were infused with one of the study drugs (vasopressin, 149; norepinephrine, 151). The primary outcome occurred in 32% of the vasopressin patients and in 49% of the norepinephrine patients (unadjusted hazard ratio, 0.55; 95% CI, 0.38 to 0.80; P = 0.0014). Regarding adverse events, the authors found a lower occurrence of atrial fibrillation in the vasopressin group (63.8% vs. 82.1%; P = 0.0004) and no difference between groups in the rates of digital ischemia, mesenteric ischemia, hyponatremia, and myocardial infarction. Conclusions: The authors' results suggest that vasopressin can be used as a first-line vasopressor agent in postcardiac surgery vasoplegic shock and improves clinical outcomes.
