Uso de oxigênio puro e shunt veno-arterial nos oxigenadores de membrana

Abstract: Cinqüenta pacientes (32 masculinos e 18 femininos) com idade variando entre 31 e 82 anos, peso entre 43 e 98 kg foram submetidos a perfusão normotérmica (34°C a 36°C) e hemodiluição, com o oxigenador de membrana (DMG). Empregou-se um shunt entre a linha arterial e venosa de modo que só uma porcentagem do sangue venoso passou pelo oxigenador. O volume do shunt foi controlado por torniquete graduado e o fluxo constantemente medido por um fluxômetro eletrônico (Biopump). Também a saturação arterial e venosa de he… Show more

“…First-generation Brazilian cardiac surgeons were not just spectators [ 1 ] , but participants in the development of surgical procedures in the treatment of coronary artery disease [ 2 , 3 ] , heart failure [ 4 , 5 ] , valvular heart surgery [ 6 , 7 ] , congenital heart surgery [ 8 - 10 ] and many others [ 11 , 12 ] . In addition, they developed expertise in the manufacture of medical equipment in Brazil, such as heart lung machine [ 13 , 14 ] , oxygenators [ 15 , 16 ] , pacemakers [ 17 ] , valves [ 18 - 20 ] , stents [ 21 ] and many others [ 1 ] .…”

“…The mixing of oxygenated and non-oxygenated blood with SaO 2 = 62% in the thoracic aorta is sufficient for the fetus because their metabolic needs are reduced [36]. Moraes [37] published a comparative where he noted that there was less bleeding and a lesser need for transfusions in the group using veno-arterial shunts.…”

“…Professor Domingos was always very creative, and in 1997 he published in the Brazilian Journal of Cardiovascular Surgery (BJCVS) an article [1] with a new concept in the extracorporeal circulation. The article’s title was ‘Use of pure oxygen and venous-arterial shunt in membrane oxygenators’.…”
