Vivien Thomas - Working With Blalock

Working With Blalock

Thomas and Blalock did groundbreaking research into the causes of hemorrhagic and traumatic shock. This work later evolved into research on Crush syndrome and saved the lives of thousands of soldiers on the battlefields of World War II. In hundreds of flawlessly executed experiments, the two disproved traditional theories which held that shock was caused by toxins in the blood. Blalock, a highly original scientific thinker and something of an iconoclast, had theorized that shock resulted from fluid loss outside the vascular bed and that the condition could be effectively treated by fluid replacement. Assisted by Thomas, he was able to provide incontrovertible proof of this theory, and in so doing, he gained wide recognition in the medical community by the mid 1930s. At this same time, Blalock and Thomas began experimental work in vascular and cardiac surgery, defying medical taboos against operating upon the heart. It was this work that laid the foundation for the revolutionary lifesaving surgery they were to perform at Johns Hopkins a decade later.

Famous quotes containing the word working:

    In most other modern societies working mothers are not put under these special and exaggerated pressures. For example, French and English mothers often prefer to breast-feed their babies, but they do not feel that their womanhood is at stake if they fail to do so. Nor does anyone else.
    Sylvia Ann Hewitt (20th century)
