Estudo comparativo experimental da distribuição do fluxo arterial, em isquemia e reperfusão por circulação retrógrada, através de mapeamento dúplex

Resumo A isquemia crítica de membro inferior sem leito distal tem opções restritas para tratamento. Desviar o fluxo sanguíneo de maneira retrógrada através da circulação venosa é uma alternativa amparada em evidências de inúmeros trabalhos publicados. Comparou-se através de mapeamento dúplex...

Membrana de circulación extracorpórea en shock obstructivo secundario a enfermedad linfoproliferativa
Oxygenation with extracorporeal membrane in obstructive shock secondary to lymphoproliferative disease

Medicina (B.Aires); 79 (6), 2019
La membrana de oxigenación extracorpórea arteriovenosa se utiliza cuando ocurre falla hemodinámica y respiratoria refractaria al tratamiento convencional; brinda soporte hemodinamico transitorio, oxigenacion y remocion de CO2, y permite reposo pulmonar. Asimismo ofrece la posibilidad de realizar venti...

The effects of remifentanil used during cesarean section on oxidative stress markers in correlation with maternal hemodynamics and neonatal outcome: a randomized controlled trial

Rev. bras. anestesiol; 69 (6), 2019
Abstract Background and objective: Remifentanil is used to attenuate maternal hemodynamic response to intubation and surgical stress during Induction-Delivery period of cesarean section. The goal was to compare the effects of two remifentanil dosing regimens on oxidative stress level, in correlation wit...

Comparison of volume-controlled and pressure-controlled ventilation on respiratory mechanics in laparoscopic bariatric surgery: randomized clinical trial

Rev. bras. anestesiol; 69 (6), 2019
Abstract Background: It is not clear which mechanical ventilation mode should be used in bariatric surgery, one of the treatment options for patients with obesity. Objectives: To compare volume-controlled ventilation and pressure-controlled ventilation in terms of respiratory mechanics and arterial blo...

Intermittent loss of consciousness during cesarean section under spinal anesthesia: a case report

Rev. bras. anestesiol; 69 (6), 2019
Abstract Loss of consciousness during spinal anesthesia is a rare but scary complication. This complication is generally related to severe hypotension and bradycardia, but in this case, the loss of consciousness occurred in a hemodynamically stable parturient patient. We present a 31 years-old patient wh...

Impact of lung expansion therapy using positive end-expiratory pressure in mechanically ventilated patients submitted to coronary artery bypass grafting

Abstract Objective: To evaluate the impact of different levels of positive end-expiratory pressure (PEEP) on gas exchange in patients undergoing coronary artery bypass grafting (CABG). Methods: A randomized clinical trial was conducted with patients undergoing CABG surgery. Patients were randomized int...

Effect of simulated geomagnetic activity on myocardial ischemia/reperfusion injury in rats

Abstract Objective: To study the response of myocardial ischemia/reperfusion injury (MI/RI) in rats to simulated geomagnetic activity. Methods: In a simulated strong geomagnetic outbreak, the MI/RI rat models were radiated, and their area of myocardial infarction, hemodynamic parameters, creatine kinas...
