1. Anesthesia for renal transplantation in patients with dilated cardiomyopathy: a retrospective study of 31 cases
Resumo Justificativa e objetivos A cardiomiopatia dilatada é um estado de aumento progressivo das câmaras cardíacas, principalmente do ventrículo esquerdo, que leva à diminuição do débito cardíaco e, por fim, à insuficiência cardíaca. Embora tenha etiologia multifatorial, é bastante comum em pacientes com doença renal terminal que precisam de

2. Effects of experimental pulmonary hemodynamic overload on cardiovascular system and pulmonary structural and function / Efeitos da sobrecarga hemodinâmica pulmonar experimental no sistema cardiovascular e na estrutura e função pulmonar
INTRODUCTION: The pulmonary hemodynamic overload (PHO) is associates to high mortality and morbidity clinical entities as: postpneumonectomy pulmonary edema, pulmonary thromboembolism, lung transplantation and physiological situations as physical exercise. Some pathophysiological aspects related to PHO are not elucidated. OBJECTIVES: To study pulmonary and c

3. Induction of apoptosis in A549 pulmonary cells by two Paracoccidioides brasiliensis samples
Paracoccidioidomycosis presents a variety of clinical manifestations and Paracoccidioides brasiliensis can reach many tissues, most importantly the lungs. The ability of the pathogen to interact with host surface structures is essential to its virulence. The interaction between P. brasiliensis and epithelial cells has been studied, with particular emphasis o

4. Effects of different peep levels on mesenteric leukocyte-endothelial interactions in rats during mechanical ventilation
INTRODUCTION: Mechanical ventilation with positive end expiratory pressure (PEEP) improves oxygenation and treats acute pulmonary failure. However, increased intrathoracic pressure may cause regional blood flow alterations that may contribute to mesenteric ischemia and gastrointestinal failure. We investigated the effects of different PEEP levels on mesenter

5. Effects of pressure controlled ventilation and volume controlled ventilation on pulmonary function in cardiac surgery patients with cardiopulmonary bypass / Efeitos do suporte ventilatorio com pressão controlada e volume controlado na função pulmonar dos pacientes submetidos a cirurgia cardiaca com circulação extra-corporea
Postoperative lung injury after cardiac surgery with cardiopulmonary bypass (CPB) is usually related to the systemic inflammatory response syndrome (SIRS). Many patients undergoing this procedure develop acute lung injury (ALI), and some of them acute respiratory distress syndrome (ARDS). Many factors can be directly or indirectly related to the postoperativ

6. Effects of noninvasive ventilation with continuous positive pressure on the airways of oncologic patients / Efeito da ventilação não invasiva com pressão positiva contínua nas vias aéreas de pacientes oncológicos
INTRODUCTION: Respiratory failure is a common situation among cancer patients leading to high rates of mortality. Noninvasive ventilation (NIV) can help its management, but its effects are still unknown regarding the pulmonary defense mechanisms. OBJECTIVES: Observe the effect of NIV with facial mask using a flow generator with continuous positive pressure (

7. Evaluation of experimental model of isolated chronic right ventricle failure / Avaliação de modelo experimental de falência crônica isolada do ventrículo direito
Isolated chronic right ventricle (RV) dysfunction is difficult to achieve in experimental models, and sometimes very expensive. Some models require complex surgical procedures, with a high mortality rate and low reproducibility. In order to simulate the clinical status of RV failure, we have developed an experimental model of chronic RV failure by injecting

8. Avaliação in vitro e ex vivo de oxigenador de membrana de baixa resistência para o uso ECMO sem auxílio de bomba.
Introduction: Extracorporeal pulmonary assistance has been proposed as an invasive alternative to the conventional treatment when adequate oxygenation becomes impossible by mechanical ventilation. Extracorporeal membrane oxygenation (ECMO) attained using assisted circulation may cause hemolysis, coagulation disorders, an inflammatory response and complicatio

9. Circulating endothelin in children with congenital heart disease.
OBJECTIVE--To evaluate whether circulating endothelin, a peptide that is thought to play a part in mediating vascular tone, might be high in pulmonary hypertensive congenital heart disease. DESIGN--A prospective study with a radioimmunoassay technique to estimate urinary and plasma endothelin concentrations. SETTING--A supraregional referral centre for patie

10. Preoperative measurement of pulmonary vascular resistance in complete transposition of the great arteries.
Transposition of the great arteries is frequently complicated by the early onset of pulmonary vascular disease. It is difficult to measure pulmonary blood flow by the Fick principle because the pulmonary arteriovenous oxygen content difference is small and bronchial blood flow is increased in this condition. In eight patients (mean age 7.7 years, range 3 mon

11. Pulmonary blood flow distribution after banding of pulmonary artery.
Radioisotope lung scanning was used to investigate the distribution of pulmonary blood flow after banding of the pulmonary artery in children with a left-to-right shunt and pulmonary hypertension. An abnormal distribution of blood flow in the lung on the side of the operation approach was observed in all patients in the first three weeks following surgery. A
