- Blood transfusion in cardiac surgery is a risk factor for increased hospital length of stay in adult patients(2013) GALAS, Filomena R. B. G.; ALMEIDA, Juliano P.; FUKUSHIMA, Julia T.; OSAWA, Eduardo A.; NAKAMURA, Rosana E.; SILVA, Carolina M. P. D. C.; ALMEIDA, Elisangela Pinto Marinho de; AULER JR., Jose Otavio Costa; VINCENT, Jean-Louis; HAJJAR, Ludhmila A.Background: Allogeneic red blood cell (RBC) transfusion has been proposed as a negative indicator of quality in cardiac surgery. Hospital length of stay (LOS) may be a surrogate of poor outcome in transfused patients. Methods: Data from 502 patients included in Transfusion Requirements After Cardiac Surgery (TRACS) study were analyzed to assess the relationship between RBC transfusion and hospital LOS in patients undergoing cardiac surgery and enrolled in the TRACS study. Results: According to the status of RBC transfusion, patients were categorized into the following three groups: 1) 199 patients (40%) who did not receive RBC, 2) 241 patients (48%) who received 3 RBC units or fewer (low transfusion requirement group), and 3) 62 patients (12%) who received more than 3 RBC units (high transfusion requirement group). In a multivariable Cox proportional hazards model, the following factors were predictive of a prolonged hospital length of stay: age higher than 65 years, EuroSCORE, valvular surgery, combined procedure, LVEF lower than 40% and RBC transfusion of >3 units. Conclusion: RBC transfusion is an independent risk factor for increased LOS in patients undergoing cardiac surgery. This finding highlights the adequacy of a restrictive transfusion therapy in patients undergoing cardiac surgery.
- Lactated Ringer's Versus 4% Albumin on Lactated Ringer's in Early Sepsis Therapy in Cancer Patients: A Pilot Single-Center Randomized Trial(2019) PARK, Clarice Hyesuk Lee; ALMEIDA, Juliano Pinheiro de; OLIVEIRA, Gisele Queiroz de; RIZK, Stephanie Itala; FUKUSHIMA, Julia Tizue; NAKAMURA, Rosana Ely; MOURAO, Matheus Moraes; GALAS, Filomena Regina Barbosa Gomes; ABDALA, Edson; FREIRE, Maristela Pinheiro; KALIL FILHO, Roberto; JR, Jose Otavio Costa Auler; NARDELLI, Pasquale; MARTIN, Greg S.; LANDONI, Giovanni; HAJJAR, Ludhmila AbrahaoObjective: To investigate the effects of the administration of 4% albumin on lactated Ringer's, when compared with lactated Ringer's alone, in the early phase of sepsis in cancer patients. Design: Single-center, randomized, double-blind, controlled-parallel trial. Setting: A tertiary care university cancer hospital. Patients: Cancer patients with severe sepsis or septic shock. Interventions: Between October 2014 and December 2016, patients were randomly assigned to receive either bolus of albumin in a lactated Ringer's solution or lactated Ringer's solution alone during the first 6 hours of fluid resuscitation after intensive care medicine (ICU) admission. Primary outcome was defined as death from any cause at 7 days. Secondary outcomes were defined as death from any cause within 28 days, change in Sequence Organ Failure Assessment scores from baseline to day 7, days alive and free of mechanical ventilation, days alive and free of vasopressor, renal replacement therapy during ICU stay, and length of ICU and hospital stay. Measurements and Main Results: A total of 360 patients were enrolled in the trial. At 7 days, 46 of 180 patients (26%) died in the albumin group and 40 of 180 (22%) died in the lactated Ringer's group (p = 0.5). At 28 days, 96 of 180 patients (53%) died in the albumin group and 83 of 180 (46%) died in the lactated Ringer's group (p = 0.2). No significant differences in secondary outcomes were observed. Conclusions: Adding albumin to early standard resuscitation with lactated Ringer's in cancer patients with sepsis did not improve 7-day survival.
- Liberal Versus Restrictive Transfusion Strategy in Critically Ill Oncologic Patients: The Transfusion Requirements in Critically Ill Oncologic Patients Randomized Controlled Trial(2017) BERGAMIN, Fabricio S.; ALMEIDA, Juliano P.; LANDONI, Giovanni; GALAS, Filomena R. B. G.; FUKUSHIMA, Julia T.; FOMINSKIY, Evgeny; PARK, Clarice H. L.; OSAWA, Eduardo A.; DIZ, Maria P. E.; OLIVEIRA, Gisele Q.; FRANCO, Rafael A.; NAKAMURA, Rosana E.; ALMEIDA, Elisangela M.; ABDALA, Edson; FREIRE, Maristela P.; FILHO, Roberto K.; AULER JR., Jose Otavio C.; HAJJAR, Ludhmila A.Objective: To assess whether a restrictive strategy of RBC transfusion reduces 28-day mortality when compared with a liberal strategy in cancer patients with septic shock. Design: Single center, randomized, double-blind controlled trial. Setting: Teaching hospital. Patients: Adult cancer patients with septic shock in the first 6 hours of ICU admission. Interventions: Patients were randomized to the liberal (hemoglobin threshold, < 9 g/dL) or to the restrictive strategy (hemoglobin threshold, < 7 g/dL) of RBC transfusion during ICU stay. Measurements and Main Results: Patients were randomized to the liberal (n = 149) or to the restrictive transfusion strategy (n = 151) group. Patients in the liberal group received more RBC units than patients in the restrictive group (1 [0-3] vs 0 [0-2] unit; p<0.001). At 28 days after randomization, mortality rate in the liberal group (primary endpoint of the study) was 45% (67 patients) versus 56% (84 patients) in the restrictive group (hazard ratio, 0.74; 95% CI, 0.53-1.04; p = 0.08) with no differences in ICU and hospital length of stay. At 90 days after randomization, mortality rate in the liberal group was lower (59% vs 70%) than in the restrictive group (hazard ratio, 0.72; 95% CI, 0.53-0.97; p = 0.03). Conclusions: We observed a survival trend favoring a liberal transfusion strategy in patients with septic shock when compared with the restrictive strategy. These results went in the opposite direction of the a priori hypothesis and of other trials in the field and need to be confirmed.
- Transfusion Requirements in Surgical Oncology Patients A Prospective, Randomized Controlled Trial(2015) ALMEIDA, Juliano Pinheiro de; VINCENT, Jean-Louis; GALAS, Filomena Regina Barbosa Gomes; ALMEIDA, Elisangela Pinto Marinho de; FUKUSHIMA, Julia T.; OSAWA, Eduardo A.; BERGAMIN, Fabricio; PARK, Clarice Lee; NAKAMURA, Rosana Ely; FONSECA, Silvia M. R.; CUTAIT, Guilherme; ALVES, Joseane Inacio; BAZAN, Mellik; VIEIRA, Silvia; SANDRINI, Ana C. Vieira; PALOMBA, Henrique; RIBEIRO JR., Ulysses; CRIPPA, Alexandre; DALLOGLIO, Marcos; DIZ, Maria del Pilar Estevez; KALIL FILHO, Roberto; AULER JR., Jose Otavio Costa; RHODES, Andrew; HAJJAR, Ludhmila AbrahaoBackground: 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.
