Drawback: the techniques were blind and limited to those that could be performed without entering the cardiac chamber. Need: better operating conditions and direct visualization of internal cardiac anatomy and pathology. EARLY EXPERIMENTS : EARLY EXPERIMENTS Original open heart surgeries and techniques developed at the university of Minnesota : Original open heart surgeries and techniques developed at the university of Minnesota John Heysham Gibbon and Mary Hopkinson : John Heysham Gibbon and Mary Hopkinson Gibbon's Research : Gibbon's Research An American surgeon named John H. Gibbon Jr. (1903-1974). In 1931 he began pursuing the goal of total artificial circulation after a young female patient died of blocked lung circulation. Gibbon realized that it was necessary to keep oxygenated blood circulating without use of the heart, especially to the brain, to carry out careful operations on the heart under direct vision. De Bakey roller pump. : De Bakey roller pump. Gibbon moved to Jefferson medical college, built a heart lung machine using 2 roller pumps designed by Michall de Bakey in 1934. Had sufficient capacity to replace the heart and lungs of expt. Cats, but was too small to serve for dogs & humans. Slide 13: In 1946 Thomas Watson, chairman of IBM financed & supported gibbon’s research. New heart lung machine To minimize hemolysis& prevent air bubble from entering the circulation. Extra corporeal circuit enclosed within a cabinet kept at body temperature & blood flow controlled to make constant blood volume. Slide 14: On May 6, 1953- first successfully human open heart surgery was performed. 18-year-old Cecilia Bavolek, for ASD. Slide 15: Disadvantages- massive, complicated, and difficult to manage. It damaged blood elements and caused bleeding problems and severe consumption of red blood cells. Because of its ability to permit corrective operations to be performed inside the human heart for the first time, however, these drawbacks of heart-lung bypass were considered acceptable. The era of open heart surgery had begun. Open Heart Surgeries with total CPB : Open Heart Surgeries with total CPB Controlled Cross-Circulation for CPB : Controlled Cross-Circulation for CPB A: pt. with AV cannulations. B:donor with AV cannulation.(sup. Femoral & Great Saphenous) C: single sigmamotor pump- reciprocal exchange of blood. D: pt’s heart with vena caval catheter. Arterial blood from the donor circulated to the pt’s body through the lft. Subclavian artery cannula. “Many are the trysts I’ve had with the mortals here.Their bodies offered to my trust,to cut and sew and maybe CURE!!” : “Many are the trysts I’ve had with the mortals here.Their bodies offered to my trust,to cut and sew and maybe CURE!!” JOHN HEYSHAM GIBBON,Jr. 1960.
