    Evaluation of hemodynamic effects of xenon in dogs undergoing hemorrhagic shock
    (2013) FRANCESCHI, Ruben C.; MALBOUISSON, Luiz; YOSHINAGA, Eduardo; AULER JR., Jose Otavio Costa; FIGUEIREDO, Luiz Francisco Poli de; CARMONA, Maria Jose C.
    OBJECTIVES: The anesthetic gas xenon is reported to preserve hemodynamic stability during general anesthesia. However, the effects of the gas during shock are unclear. The objective of this study was to evaluate the effect of Xe on hemodynamic stability and tissue perfusion in a canine model of hemorrhagic shock. METHOD: Twenty-six dogs, mechanically ventilated with a fraction of inspired oxygen of 21% and anesthetized with etomidate and vecuronium, were randomized into Xenon (Xe; n = 13) or Control (C; n = 13) groups. Following hemodynamic monitoring, a pressure-driven shock was induced to reach an arterial pressure of 40 mmHg. Hemodynamic data and blood samples were collected prior to bleeding, immediately after bleeding and 5, 20 and 40 minutes following shock. The Xe group was treated with 79% Xe diluted in ambient air, inhaled for 20 minutes after shock. RESULT: The mean bleeding volume was 44 mL.kg(-1) in the C group and 40 mL.kg(-1) in the Xe group. Hemorrhage promoted a decrease in both the cardiac index (p<0.001) and mean arterial pressure (p<0.001). These changes were associated with an increase in lactate levels and worsening of oxygen transport variables in both groups (p<0.05). Inhalation of xenon did not cause further worsening of hemodynamics or tissue perfusion markers. CONCLUSIONS: Xenon did not alter hemodynamic stability or tissue perfusion in an experimentally controlled hemorrhagic shock model. However, further studies are necessary to validate this drug in other contexts.

    TREATMENT WITH HUMAN UMBILICAL CORD-DERIVED MESENCHYMAL STEM CELLS IN A PIG MODEL OF SEPSIS-INDUCED ACUTE KIDNEY INJURY: EFFECTS ON MICROVASCULAR ENDOTHELIAL CELLS AND TUBULAR CELLS IN THE KIDNEY
    (2023) MAIA, Debora Rothstein Ramos; OTSUKI, Denise Aya; RODRIGUES, Camila Eleuterio; ZBORIL, Sabrina; SANCHES, Talita Rojas; NETO, Amaro Nunes Duarte; ANDRADE, Lucia; AULER, Jose Otavio Costa
    Background: Approximately 50% of patients with sepsis develop acute kidney injury (AKI), which is predictive of poor outcomes, with mortality rates of up to 70%. The endothelium is a major target for treatments aimed at preventing the complications of sepsis. We hypothesized that human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) could attenuate tubular and endothelial injury in a porcine model of sepsis-induced AKI. Methods: Anesthetized pigs were induced to fecal peritonitis, resulting in septic shock, and were randomized to treatment with fluids, vasopressors, and antibiotics (sepsis group; n = 11) or to that same treatment plus infusion of 1 x 106 cells/kg of hUC-MSCs (sepsis+MSC group; n = 11). Results: At 24 h after sepsis induction, changes in serum creatinine and mean arterial pressure were comparable between the two groups, as was mortality. However, the sepsis+MSC group showed some significant differences in comparison with the sepsis group: lower fractional excretions of sodium and potassium; greater epithelial sodium channel protein expression; and lower protein expression of the Na-K-2Cl cotransporter and aquaporin 2 in the renal medulla. Expression of P-selectin, thrombomodulin, and vascular endothelial growth factor was significantly lower in the sepsis+MSC group than in the sepsis group, whereas that of Toll-like receptor 4 (TLR4) and nuclear factor-kappa B (NF-kappa B) was lower in the former. Conclusion: Treatment with hUC-MSCs seems to protect endothelial and tubular cells in sepsis-induced AKI, possibly via the TLR4/NF-kappa B signaling pathway. Therefore, it might be an effective treatment for sepsis-induced AKI.

    PEEP-ZEEP technique: cardiorespiratory repercussions in mechanically ventilated patients submitted to a coronary artery bypass graft surgery
    (2011) HERBST-RODRIGUES, Marcus Vinicius; CARVALHO, Vitor Oliveira; AULER JR., Jose Otavio Costa; FELTRIM, Maria Ignez Zanetti
    Background: The PEEP-ZEEP technique is previously described as a lung inflation through a positive pressure enhancement at the end of expiration (PEEP), followed by rapid lung deflation with an abrupt reduction in the PEEP to 0 cmH(2)O (ZEEP), associated to a manual bilateral thoracic compression. Aim: To analyze PEEP-ZEEP technique's repercussions on the cardio-respiratory system in immediate postoperative artery graft bypass patients. Methods: 15 patients submitted to a coronary artery bypass graft surgery (CABG) were enrolled prospectively, before, 10 minutes and 30 minutes after the technique. Patients were curarized, intubated, and mechanically ventilated. To perform PEEP-ZEEP technique, saline solution was instilled into their orotracheal tube than the patient was reconnected to the ventilator. Afterwards, the PEEP was increased to 15 cmH(2)O throughout 5 ventilatory cycles and than the PEEP was rapidly reduced to 0 cmH(2)O along with manual bilateral thoracic compression. At the end of the procedure, tracheal suction was accomplished. Results: The inspiratory peak and plateau pressures increased during the procedure (p < 0.001) compared with other pressures during the assessment periods; however, they were within lung safe limits. The expiratory flow before the procedure were 33 +/- 7.87 L/min, increasing significantly during the procedure to 60 +/- 6.54 L/min (p < 0.001), diminishing to 35 +/- 8.17 L/min at 10 minutes and to 36 +/- 8.48 L/min at 30 minutes. Hemodynamic and oxygenation variables were not altered. Conclusion: The PEEP-ZEEP technique seems to be safe, without alterations on hemodynamic variables, produces elevated expiratory flow and seems to be an alternative technique for the removal of bronchial secretions in patients submitted to a CABG.

    Comparison of Inhaled Nitric Oxide Versus Oxygen on Hemodynamics in Patients With Mitral Stenosis and Severe Pulmonary Hypertension After Mitral Valve Surgery
    (2011) FERNANDES, Juliano L.; SAMPAIO, Roney O.; BRANDAO, Carlos M.; ACCORSI, Tarso Augusto D.; CARDOSO, Luiz F.; SPINA, Guilherme S.; TARASOUTCHI, Flavio; POMERANTZEFF, Pablo; AULER JR., Jose O.; GRINBERG, Max
    Pulmonary hypertension represents an important cause of morbidity and mortality in patients with mitral stenosis who undergo cardiac surgery, especially in the postoperative period. The aim of this study was to test the hypothesis that inhaled nitric oxide (iNO) would improve the hemodynamic effects and short-term clinical outcomes of patients with mitral stenosis and severe pulmonary hypertension who undergo cardiac surgery in a randomized, controlled study. Twenty-nine patients (4 men, 25 women; mean age 46 2 years) were randomly allocated to receive iNO (n = 14) or oxygen (n = 15) for 48 hours immediately after surgery. Hemodynamic data, the use of vasoactive drugs, duration of stay, and short-term complications were assessed. No differences in baseline characteristics were observed between the groups. After 24 and 48 hours, patients receiving iNO had a significantly greater increase in cardiac index compared to patients receiving oxygen (p < 0.0001). Pulmonary vascular resistance was also more significantly reduced in patients receiving iNO versus oxygen (-117 dyne/s/cm(5), 95% confidence interval 34 to 200, vs 40 dyne/s/cm5, 95% confidence interval 34 to 100, p = 0.005) at 48 hours. Patients in the iNO group used fewer systemic vasoactive drugs.(mean 2.1 +/- 0.14 vs 2.6 +/- 0.16, p = 0.046) and had a shorter intensive care unit stay (median 2 days, interquartile range 0.25, vs median 3 days, interquartile range 7, p = 0.02). In conclusion, iNO immediately after surgery in patients with mitral stenosis and severe pulmonary hypertension improves hemodynamics and may have short-term clinical benefits.

    Effect of a Perioperative Intra-Aortic Balloon Pump in High-Risk Cardiac Surgery Patients: A Randomized Clinical Trial
    (2018) FERREIRA, Graziela Santos Rocha; ALMEIDA, Juliano Pinheiro de; LANDONI, Giovanni; VINCENT, Jean Louis; FOMINSKIY, Evgeny; GALAS, Filomena Regina Barbosa Gomes; GAIOTTO, Fabio A.; DALLAN, Luis Oliveira; FRANCO, Rafael Alves; LISBOA, Luiz Augusto; DALLAN, Luis Roberto Palma; FUKUSHIMA, Julia Tizue; RIZK, Stephanie Itala; PARK, Clarice Lee; STRABELLI, Tania Mara; LAGE, Silvia Helena Gelas; CAMARA, Ligia; ZEFERINO, Suely; JARDIM, Jaquelline; ARITA, Elisandra Cristina Trevisan Calvo; RIBEIRO, Juliana Caldas; AYUB-FERREIRA, Silvia Moreira; AULER JR., Jose Otavio Costa; KALIL FILHO, Roberto; JATENE, Fabio Biscegli; HAJJAR, Ludhmila Abrahao
    Objectives: The aim of this study was to evaluate the efficacy of perioperative intra-aortic balloon pump use in high-risk cardiac surgery patients. Design: A single-center randomized controlled trial and a meta-analysis of randomized controlled trials. Setting: Heart Institute of SAo Paulo University. Patients: High-risk patients undergoing elective coronary artery bypass surgery. Intervention: Patients were randomized to receive preskin incision intra-aortic balloon pump insertion after anesthesia induction versus no intra-aortic balloon pump use. Measurements and Main Results: The primary outcome was a composite endpoint of 30-day mortality and major morbidity (cardiogenic shock, stroke, acute renal failure, mediastinitis, prolonged mechanical ventilation, and a need for reoperation). A total of 181 patients (mean [sd] age 65.4 [9.4] yr; 32% female) were randomized. The primary outcome was observed in 43 patients (47.8%) in the intra-aortic balloon pump group and 42 patients (46.2%) in the control group (p = 0.46). The median duration of inotrope use (51hr [interquartile range, 32-94 hr] vs 39hr [interquartile range, 25-66 hr]; p = 0.007) and the ICU length of stay (5 d [interquartile range, 3-8 d] vs 4 d [interquartile range, 3-6 d]; p = 0.035) were longer in the intra-aortic balloon pump group than in the control group. A meta-analysis of 11 randomized controlled trials confirmed a lack of survival improvement in high-risk cardiac surgery patients with perioperative intra-aortic balloon pump use. Conclusions: In high-risk patients undergoing cardiac surgery, the perioperative use of an intra-aortic balloon pump did not reduce the occurrence of a composite outcome of 30-day mortality and major complications compared with usual care alone.

    A pragmatic multi-center trial of goal-directed fluid management based on pulse pressure variation monitoring during high-risk surgery
    (2017) MALBOUISSON, Luiz Marcelo Sa; SILVA JR., Joao Manoel; CARMONA, Maria Jose Carvalho; LOPES, Marcel Rezende; ASSUNCAO, Murilo Santucci; VALIATTI, Jorge Luis dos Santos; SIMOES, Claudia Marques; AULER JR., Jose Otavio Costa
    Background: Intraoperative fluid therapy guided by mechanical ventilation-induced pulse-pressure variation (PPV) may improve outcomes after major surgery. We tested this hypothesis in a multi-center study. Methods: The patients were included in two periods: a first control period (control group; n = 147) in which intraoperative fluids were given according to clinical judgment. After a training period, intraoperative fluid management was titrated to maintain PPV < 10% in 109 surgical patients (PPV group). We performed 1:1 propensity score matching to ensure the groups were comparable with regard to age, weight, duration of surgery, and type of operation. The primary endpoint was postoperative hospital length of stay. Results: After matching, 84 patients remained in each group. Baseline characteristics, surgical procedure duration and physiological parameters evaluated at the start of surgery were similar between the groups. The volume of crystalloids (4500 mL [3200-6500 mL] versus 5000 mL [3750-8862 mL]; P = 0.01), the number of blood units infused during the surgery (1.7 U [0.9-2.0 U] versus 2.0 U [1.7-2.6 U]; P = 0.01), the fraction of patients transfused (13.1% versus 32.1%; P = 0.003) and the number of patients receiving mechanical ventilation at 24 h (3.2% versus 9.7%; P = 0.027) were smaller postoperatively in PPV group. Intraoperative PPV-based improved the composite outcome of postoperative complications OR 0.59 [95% CI 0.35-0.99] and reduced the postoperative hospital length of stay (8 days [6-14 days] versus 11 days [7-18 days]; P = 0.01). Conclusions: In high-risk surgeries, PPV-directed volume loading improved postoperative outcomes and decreased the postoperative hospital length of stay.

    Experimental Model of Non-Controlled Hemorrhagic Shock in Pigs
    (2011) CAVALCANTE, Fernanda Paula; NANI, Ricardo Souza; ROCHA FILHO, Joel Avancini; AULER JUNIOR, Jose Otavio Costa; CARMONA, Maria Jose Carvalho; MACHADO, Marcel Cerqueira Cesar
    Cavalcante FP, Nani RS, Rocha Filho JA, Auler Junior JOC, Carmona MJC, MachadoMCC - Experimental Model of Non-Controlled Hemorrhagic Shock in Pigs. Background and objectives: A better understanding of pathophysiologic changes associated to trauma and hemorrhagic shock can help the development of therapies capable of reducing trauma-related mortality. The objective of this study was to describe a model of non-controlled hemorrhagic shock in pigs. Methods: Animals received ketamine and midazolam as pre-anesthetic medications. Anesthesia was induced with propofol, and tracheal intubation was performed with the animals on spontaneous ventilation. After intubation neuromuscular blockade was performed. Animals were maintained in controlled mechanical ventilation and normocapnia. Anesthesia was maintained with propofol and fentanyl as needed. Saline was infused during the entire preparation period. Monitoring: Cardioscope, pulse oximeter, invasive blood pressure, volumetric catheter in the pulmonary artery, and urine output by cystostomy were used. Experimental model: after the initial recording of hemodynamic, metabolic, and coagulation variables, right subcostal incision and left lobe liver biopsy were performed. Anesthetic infusion was reduced while the infusion of saline was interrupted. An incision 12 cm long 2 cm deep was performed in the right liver lobe followed by digital divulsion of the wound. During the hemorrhagic phase, an aspiration probe was placed close to the wound and the volume of aspirated blood was recorded. When mean arterial pressure reached 40 mmHg and bleeding was above 700 mL the intervention phase was initiated according to the type of study. Conclusion: The development of experimental models to reduce high mortality and costs related to trauma is important.

    The effect of premedication with ketamine, alone or with diazepam, on anaesthesia with sevoflurane in parrots (Amazona aestiva)
    (2013) PAULA, Valeria Veras; OTSUKI, Denise Aya; AULER JUNIOR, Jose Otavio Costa; NUNES, Talyta Lins; AMBROSIO, Aline Magalhaes; FANTONI, Denise Tabacchi
    Background: Premedication is rarely used in avian species. The aim of this study was to evaluate the effect of premedication on the quality of sevoflurane induction and anaesthesia in parrots. We hypothesised that premedication would facilitate handling and decrease the minimum anaesthetic dose (MAD). Thirty-six adult parrots were randomly distributed in three groups: group S (n = 12) was premedicated with NaCl 0.9%; group KS (n = 12) was premedicated with 10 mg.kg(-1) ketamine; and group KDS (n = 12) was premedicated with 10 mg.kg(-1) ketamine and 0.5 mg.kg(-1) diazepam, delivered intramuscularly. After induction using 4.5% sevoflurane introduced through a facemask, the MAD was determined for each animal. The heart rate (HR), respiratory rate (RR), systolic arterial blood pressure (SAP), and cloacal temperature (CT) were recorded before premedication (T0), 15 minutes after premedication (T1), and after MAD determination (T2). Arterial blood gas analyses were performed at T0 and T2. The quality of anaesthesia was evaluated using subjective scales based on animal behaviour and handling during induction, maintenance, and recovery. Statistical analyses were performed using analysis of variance or Kruskal-Wallis tests followed by Tukey's or Dunn's tests. Results: The minimal anaesthetic doses obtained were 2.4 +/- 0.37%, 1.7 +/- 0.39%, and 1.3 +/- 0.32% for groups S, KS, and KDS, respectively. There were no differences in HR, RR, or CT among groups, but SAP was significantly lower in group S. Sedation was observed in both the premedicated S-KS and S-KDS groups. There were no differences in the quality of intubation and recovery from anaesthesia among the three groups, although the induction time was significantly shorter in the pre-medicated groups, and the KS group showed less muscle relaxation. Conclusions: Ketamine alone or the ketamine/diazepam combination decreased the MAD of sevoflurane in parrots (Amazona aestiva). Ketamine alone or in combination with diazepam promoted a good quality of sedation, which improved handling and reduced the stress of the birds. All protocols provided safe anaesthesia in this avian species.

    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.
