Pierre Potain
Pierre Carl Edouard Potain ( born July 19, 1825 Paris, France; † January 8, 1901 in Paris) was a French internist.
Family
The family was traditionally prescribed to the medical profession, his father had to study medicine but not completed, but had become postmaster in Saint- Germain. His father led Potain in the woods of Saint- Germain and taught him everything he knew about grammar, literature and the natural sciences, from his mother he learned the German language.
Education and work
Since funds for education were not available, Potain learned all by itself, was accepted at the University of Paris and reached here a first successful conclusion. First, he wanted to deal with the science and mechanics, but the medicine turned to then. After graduating, he worked from 1848 in the hospitals of Paris (internal ). During the great cholera epidemic ( 1849) was Potain assistant physician at the Salpêtrière. There he fell sick with cholera, recovered, became ill again and survived.
1853 Potain doctorate at the University of Paris and then accepted a position as assistant to Jules Gabriel François Baillarder ( 1806-1891 ) in the madhouse of Ivry. In 1856 he again worked in Paris at the clinic by Jean -Baptiste Bouillaud ( 1796-1881 ) as the head physician and in other hospitals ( the Ménages, Sainte- Antoine, Hôpital Necker ). He also took over smaller teaching at the university. In 1861 Potain was admitted to all hospitals ( Doctor of hôpitaux ) and appointed associate professor of the medical faculty of the University of Paris ( Professeur agrégé ).
During the Franco-German War, he was to lead a military hospital company, but insisted to draw as a soldier in the field. Nevertheless, he provided as part of its possibility the wounded in the hospitals. In 1876 Potain was appointed to the Chair of Pathology at the University of Paris, but soon moved to the chair of clinical medicine. In 1882 he worked at the Hôpital de la Charité, where he remained until his retirement in 1900.
Performance
Potain dealt not only with methods of pulse recording, but also pointed to the close relationship of tricuspid regurgitation and circulatory disorders and liver pulsation. He distinguished between different types of cardiac gallop rhythm, explained the mechanism of the cardiac apex beat and recognized the paukende noise of the second heart sound in syphilitic aortitis.
With enthusiasm he greeted the sphygmomanometer of Basch and developed it in 1889 to a usable in clinical performance instrument further. The application of his blood pressure led him on such other findings: He showed that Bright 's disease ( nephritis parenchymatous ) is associated with hypertension, the high-pressure disease discovered in other pathological conditions and as a cause of cardiac hypertrophy in renal arteriosclerosis.
He improved a device for counting the red blood cells ( Malassez Hämatometer ) and constructed a Aspirationsapparat, who worked with a vacuum pump. In patients with extreme shortness of breath, he led a thoracentesis by, removed the liquid with his aspirator and joined to another home-built apparatus, which zuführte air gradually again.
Potain was a member of the Académie de Médecine (1883 ), the Académie des Sciences ( 1893) and Commander of the Legion of Honour (1895 ). In the 19th arrondissement of Paris, a street is named after him ( Rue du Docteur Potain ).
