Hepatic Trauma: A 21-year Experience [trauma Hepático: Uma Experiência De 21 Anos]
No full textObjective: To evaluate the epidemiological aspects, behavior, morbidity and treatment outcomes for liver trauma. Methods: We conducted a retrospective study of patients over 13 years of age admitted to a university hospital from 1990 to 2010, submitted to surgery or nonoperative management (NOM). Results: 748 patients were admitted with liver trauma. The most common mechanism of injury was penetrating trauma (461 cases, 61.6%), blunt trauma occurring in 287 patients (38.4%). According to the degree of liver injury (AAST-OIS) in blunt trauma we predominantly observed Grades I and II and in penetrating trauma, Grade III. NOM was performed in 25.7% of patients with blunt injury. As for surgical procedures, suturing was performed more frequently (41.2%). The liver-related morbidity was 16.7%. The survival rate for patients with liver trauma was 73.5% for blunt and 84.2% for penetrating trauma. Mortality in complex trauma was 45.9%. Conclusion: trauma remains more common in younger populations and in males. There was a reduction of penetrating liver trauma. NOM proved safe and effective, and often has been used to treat patients with penetrating liver trauma. Morbidity was high and mortality was higher in victims of blunt trauma and complex liver injuries.404318322Talving, P., Beckman, M., Häggmark, T., Iselius, L., Epidemiology of liver injuries (2003) Scand J Surg., 92 (3), pp. 192-194Diorio, A.C., Fraga, G.P., Dutra Jr., I., Joaquim, J.L., Mantovani, M., Predictive factors of morbidity and mortality in hepatic trauma (2008) Rev Col Bras Cir., 35 (6), pp. 397-405Smaniotto, B., von Bahten, L.C., Nogueira Filho, D.C., Tano, A.L., Thomaz Júnior, L., Fayad, O., Hepatic trauma: Analysis of the treatment with intrahepatic balloon in a university hospital of Curitiba (2009) Rev Col Bras Cir., 36 (3), pp. 217-222Croce, M.A., Fabian, T.C., Menke, P.G., Waddle-Smith, L., Minard, G., Kudsk, K.A., Nonoperative management of blunt hepatic trauma is the treatment of choice for hemodynamically stable patients.

Evaluatierapport “Powered by you”: Ontwikkeling Sustainable Energy Floor- energieopwekkende vloer
No full textOp weg naar rendabele energieopwekking door lopen. Er was een voorsprong in kennis en ervaring aangaande de techniek die nodig was een energie genererende loopvloer (de Sustainable Energy Floor – SEF) te realiseren. Specifieke aanpassingen moesten echter ontwikkeld worden in verband met de andere bewegingsvorm, de schaal die vele malen groter is en de andere installatie- en logistieke eisen. Het doel was om een pilot te doen op één of meer aansprekende locaties. Het project moest een belangrijke stap zijn op weg naar rendabele energieopwekking door lopen. Samen met de TU Delft, faculteit Industrieel Ontwerpen en Rinnic Vaude is onderzoek gedaan naar de haalbaarheid van het ontwikkelen van SEF, zijn prototypes en een pilotvloer gerealiseerd, tests gedaan en presentaties en demonstraties gegeven aan vele partijen en een breed publiek in Delft en Rotterdam. Vanwege technische knelpunten gedurende het project en de praktische haalbaarheid is er niet één grote pilot voor een langere periode gedaan, maar zijn er meerdere kortdurende pilots en tests gedaan. Het voordeel hiervan was dat we op basis van de analyses, tests en de feedback van gebruikers op verschillende versies prototypes, het ontwerp steeds verder konden verbeteren. Tenslotte heeft dit geresulteerd in het bouwen van de pilotvloer, waarmee de eindtest in De Kuip is uitgevoerd naar tevredenheid van alle betrokken partijen. Het project is succesvol afgerond en de doelstellingen zijn gehaald binnen het gestelde budget. Het project is uitgevoerd met steun van het programma Kansen voor West, wat valt onder het Europese Fonds voor Regionale Ontwikkeling.Industrial Design Engineerin
Decay of turbulence at high Reynolds numbers
No full textUsing the unique capabilities of the Variable Density Turbulence Tunnel at the Max Planck Institute for Dynamics and Self-Organization, we investigated virtually homogeneous and isotropic grid turbulence over a wide range of Reynolds numbers, , between and . The choice of pressurizable Sulfur Hexafluoride as a working gas makes it possible to reach extremely high Reynolds numbers without changing boundary conditions. Indeed, the Reynolds number we reached were higher than any previous classical grid wind-tunnel experiment. In this talk, we focus on the fundamental question of how fast turbulent energy decays once it has been created, and show that the Reynolds number plays no important role in setting the decay rate if it is high enough
Wall to wall optimal transport
No full textThe calculus of variations is employed to find steady divergence-free velocity fields that maximize transport of a tracer between two parallel walls held at fixed concentration for one of two constraints on flow strength: a fixed value of the kinetic energy or a fixed value of the enstrophy (the mean square rate of strain in this situation). The optimizing flows realize upper limits on convective transport in this scenario. We interpret the results in the context of buoyancy-driven Rayleigh–Bénard convection problems that satisfy the flow intensity constraints, enabling us to investigate how optimal transport scalings compare with upper bounds on Nu expressed as a function of the Rayleigh number Ra
Experiments and DNS of a round jet with turbulent inlet
No full textExperimental and Direct Numerical Simulation data of a turbulent round jet fed by a turbulent pipe are compared in the near field. The Reynolds number achieved in both the experiment and the simulation, Re = 16000, allows a direct comparison of both the average and the fluctuating velocity statistics. In the experiments the jet is fed with olive oil droplets with a Stokes number St ' 1 whose dynamics is compared against the corresponding DNS simulation to asses the ability of particles to reproduce high order turbulence statistics and to asses the accumulation properties of inertial particles in the near field
Evaluation Of Gasometric Parameters In Trauma Patients During Mobile Prehospital Care [avaliação Dos Parâmetros Gasométricos Dos Traumatizados Durante O Atendimento Pré-hospitalar Móvel]
No full textObjective: To evaluate gasometric differences of severe trauma patients requiring intubation in prehospital care. Methods: Patients requiring airway management were submitted to collection of arterial blood samples at the beginning of pre-hospital care and at arrival at the Emergency Room. We analyzed: Glasgow Coma Scale, respiratory rate, arterial pH, arterial partial pressure of CO2 (PaCO2), arterial partial pressure of O2 (PaO2), base excess (BE), hemoglobin O2 saturation (SpO2) and the relation of PaO2 and inspired O2 (PaO2/FiO2). Results: There was statistical significance of the mean differences between the data collected at the site of the accident and at the entrance of the ER as for respiratory rate (p = 0.0181), Glasgow Coma Scale (p = 0.0084), PaO2 (p <0.0001) and SpO2 (p = 0.0018). Conclusion: tracheal intubation changes the parameters PaO2 and SpO2. There was no difference in metabolic parameters (pH, bicarbonate and base excess). In the analysis of blood gas parameters between survivors and non-survivors there was statistical difference between PaO2, hemoglobin oxygen saturation and base excess.404293299Gonsaga, R.A., Brugugnolli, I.D., Fraga, G.P., Comparison between two mobile pre-hospital care services for trauma patients (2012) Word J Emerg Surg., 7 (SUPPL. 1), pp. S6Pereira Júnior, G.A., Carvalho, J.B., Ponte Filho, A.D., Malzone, D.A., Pedersoli, C.E., Transporte intra-hospitalar do paciente crítico (2007) Medicina., 40 (4), pp. 500-508Kue, R., Brown, P., Ness, C., Scheulen, J., Adverse clinical events during intrahospital transport by a specialized team: A preliminary report (2011) Am J Crit Care., 20 (2), pp. 153-161Lima Junior, N.A., Bacelar, S.C., Japiassú, A.M., Cader, S.A., Lima, R.C.F., Dantas, E.H.M., Gasometria arterial em dois diferentes métodos de transporte intra-hospitalar no pós-operatório imediato de cirurgia cardíaca (2012) Rev bras ter intensiva., 24 (2), pp. 162-166Waydhas, C., Schneck, G., Duswald, K.H., Deterioration of respiratory function after intra-hospital transport of critically ill surgical patients (1995) Intensive Care Med., 21 (10), pp. 784-789Zuchelo, L.T.S., Chiavone, P.A., Transporte intra-hospitalar de pacientes sob ventilação invasiva: Repercussões cardiorrespiratórias e eventos adversos (2009) J bras pneumol., 35 (4), pp. 367-374Gervais, H.W., Eberle, B., Konietzke, D., Hennes, H.J., Dick, W., Comparison of blood gases of ventilated patients during transport (1987) Crit Care Med., 15 (8), pp. 761-763Wildner, G., Pauker, N., Archan, S., Gemes, G., Rigaud, M., Pocivalnik, M., Arterial line in prehospital emergency settings-A feasibility study in four physician-staffed emergency medical systems (2011) Resuscitation., 82 (9), pp. 1198-1201Schmelzer, T.M., Perron, A.D., Thomason, M.H., Sing, R.F., A comparison of central venous and arterial base deficit as a predictor of survival in acute trauma (2008) Am J Emerg Med., 26 (2), pp. 119-123Bilello, J.F., Davis, J.W., Lemaster, D., Townsend, R.N., Parks, S.N., Sue, L.P., Prehospital hypotension in blunt trauma: Identifying the "crump factor" (2011) J Trauma., 70 (5), pp. 1038-1042(2012) Atendimento pré-hospitalar ao traumatizado, PHTLS / NAEMT, , Tradução do original Prehospital trauma life support, por Renata Scavone, et al. 7a ed.
