- PEDIATRIC HEART TRANSPLANTATION PROGRAM: SINGLE CENTER EXPERIENCE OF 20 YEARS(2013) AZEKA, Estela; GALAS, Filomena; TANAMATI, Carla; PENHA, Juliano; FERNANDES, Marcos; SENAHA, Luciano; XAVIER, Johnny; DELGADO, Ana Beatriz Romani; KAJITA, Luiz; AIELLO, Vera; BENVENUTI, Luiz; MIURA, Nana; AULER JUNIOR, Jose Otavio Costa; JATENE, MarceloOBJECTIVE: Heart transplantation has been the treatment of choice for children with refractory to conventional therapy. To report the experience with heart transplantation in a single center. MATERIAL AND METHODS: To report the single center experience of hearttransplantation. Data analysis was demographic characteristics, clinical outcome and survival Kaplan Meier curve. RESULTS: From October 30, 1992 to October 2nd, 2012, 120 transplants were performed and 115 patients were submitted to heart transplantation at Heart Institute (InCor) University of Sao Paulo Medical School, Sao Paulo, Brazil. The causes of indication for transplantation were: cardiomyopathies (76%) and congenital heart disease (24%). Five patients were submitted to re-transplantation. Three of them were re-transplanted on the early postoperative period with high mortality (66.6%). One patient was submitted to simultaneous re-transplantation and kidney transplantation after 13.9 yrs of follow-up and one of patient was successful re-transplanted after 10 yr of follow-up. The post-operative immunosuppression regimen was double immunosuppression and polyclonal anti-thymocyte serum induction therapy. The actuarial survival was 80%, 71%, and 61% at 1, 5, and 10 yr, respectively. CONCLUSION: Heart transplantation has been a promising option for children. The use of double immunosuppression with polyclonal anti-thymocyte serum induction therapy combined with surveillance of acute rejection with non-invasive tests may provide favorable clinical outcome.

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 CostaBackground: 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.
- Bleeding and damage control surgery(2016) RODRIGUES, Roseny R.; CARMONA, Maria Jose C.; JUNIOR, Jose Otavio C. A.Purpose of review Bleeding is still a major cause of death in trauma patients. Damage control surgery is a strategy that aims to control bleeding and avoid secondary contamination of the cavity. This article checks the principles and indications of damage control surgery, bleeding management, and the role of the anesthesiologist in trauma context. The efficient treatment of severe trauma and exsanguinated patients includes a surgical approach to the patient performed as quickly as possible. Volemic resuscitation, hemostatic transfusion, prevention and/or treatment of coagulopathy, hypothermia, and acidosis are strategies that reduce bleeding, as well as permissive hypotension. Recent findings Specialized literature shows us that the adoption of all of these principles along with reduced surgical time has led to a broader concept called damage control resuscitation. Damage control resuscitation is a treatment strategy in which the recovery of physiological variables is initially prioritized over anatomical variables and can be required in severe trauma patients.
- 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 ZanettiBackground: 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.
