Hermann Sahli
Hermann Sahli (* May 23, 1856 in Bern, † April 28, 1933 in Bern ) was a Swiss internist.
Family
The family came from Wohlen in Canton Bern. His father was a respected lawyer, government and the Council of States, his grandfather and a well-known pastor Lichenologe ( lichen researcher). Sahli was interested at an early age for the flora of his home, for science as such and the music. In 1888 he married Olga ( Leibundgut ). The marriage produced a daughter emerged.
Education and work
He attended the Literargymnasium in Bern, his preference was particularly the natural sciences, mathematics and ancient languages . After the matriculation examination in 1874 wanted to study at the local university chemistry but chose the better here represented medicine. 1878 put Sahli from the medical state examination. His teachers were the clinicians Heinrich Quincke and Ludwig Lichtheim (1845-1928), the surgeon Theodor Kocher and Theodor Langhans (1839-1915) in pathological anatomy.
First Sahli worked as an assistant at the Children's Hospital in Bern, where he received his doctorate. He then moved to the medical clinic in Bern and soon came to Leipzig, where he worked with Julius Cohnheim experimental- pathological ( formation of pulmonary edema ) and Carl Weigert histologically ( methylene blue staining). In Leipzig he met, among others, Karl Vierordt and Adolf von Strümpell. This was followed by study trips to Vienna, where he further trained in the specialized fields Laryngology and Otology, ophthalmology and dermatology, as well as to London to William R. Gowers and John Hughlings Jackson, and according to Paris Jean- Martin Charcot.
Returning to Bern, he took his assistant career again and habilitated in 1882 for Internal Medicine. 1888 Lichtheim was called to Königsberg and Sahli joined its successor as Professor of Internal Medicine. In this position he remained until 1929.
Performance
Hermann Sahli was one of the medicine actually possessed. Sahlis work stimulated considerable progress in the field of circulatory physiology, and he worked in the long years of his teaching and research activities almost all areas of internal medicine.
He dealt with the localization of the nuclei of the small hand muscles ( Ankylostomumanämie in tunnel workers at the Gotthard ), the methylene blue - acid fuchsin double staining, accidental murmurs, annular Hautgefäßektasien ( Sahli - venous ring ) and central nervous influences on gastric secretion, led salicylic acid phenolic ester ( Salole ) in the medicine one, hit the abdominal self-massage with iron balls in chronic constipation before and published in 1888 a monograph on the pathology of infectious diseases.
He recommended in febrile diseases, the infusion of physiological saline solutions and described an infusion apparatus, spoke about appendicitis, brain surgical operations Vesikuläratmung declared correctly and infused leech secretions to prevent thrombosis.
In 1894 for the first time Sahlis masterpiece, the textbook of clinical examination methods, which made him internationally known. As a result, he dealt with the preferred diagnosis of gastric function, hematology, tuberculosis, hemodynamics and neurology.
For qualitative and quantitative assessment of gastric function, he developed methods with Glutoidkapseln (1898), Desmoidkapseln (1905 ), sample meals (soup test meal ) and gavage. In 1902 he presented a haemoglobinometer ( Sahli - Hämometer ) ago with a very tough test solution ( containing hydrochloric acid hematin ) and devoted himself extensively to the study of hemophilia (1905, 1910). Appeared in 1906 a monograph on tuberculin, tuberculosis healing and immunity.
Sahli studied for nearly two decades hemodynamic issues: He described a Taschenquecksilbermanometer with pad for ambulatory blood pressure measurement ( 1904), developed the theory of the "absolute" sphygmogram (1904 ) for determining the maximum and minimum pressure and engaged from 1907 to 1920 with the peripheral measurement of the pulse energy ( Sphygmo or Volumbolometrie ) and the construction of a Arteriometers arterial caliber measurement.
On neurological field, he led pathological- anatomical studies, examined neuroses (1922 ), believed in an anatomical substrate of hysteria and a "special form of energy of the spiritual in the physical and spiritual context " ( 1931).
He has published 178 scientific papers.
