Ludwig Traube

Ludwig Traube (1818 - 1876)

Ludwig Traube (1818 – 1876) was a German physician.

He was a pioneer of physiological experimentation in clinical medicine and pathology. Remembered for his introduction of clinical thermometry in 1850 and his descriptions of Traube space; Traube pulse (pulsus bigeminus); Traube sign; and Doppelton

Co-founder of Beiträge zur experimentellen Pathologie with Reinhardt and Virchow. Two issues were published in 1846 and 1847.

Medical Eponyms

Traube sign and Traube ‘double-tone’ (1867)

Traube described two distinct sounds heard over the femoral artery in a 28 year old Prussian veteran of the Schleswig-Holstein military campaign, suffering from aortic insufficiency associated with rheumatic heart disease. Traube described the Doppelton (double tone) phenomenon when applying the stethoscope lightly over the femoral artery, so that the diameter of the vessel was not modified by compression.

Traube sign is the systolic (first) sound is caused by the rapid distension of the artery and likened to that of a pistol-shot. The Traube ‘double-tone’ is the second sound associated with the rapid change of tension of the arterial wall after the quick distension.


Traube’s space (1868)

Semilunar or crescent shaped anatomical space, overlying the gas bubble in the stomach and normally tympanitic to percussion.

  • Anatomical margins: lower border of the left lung; anterior border of the spleen; left costal margin; and inferior margin of the left lobe of the liver.
  • Surface landmarks: superiorly (left 6th rib); laterally (left mid axillary line); and inferiorly (left costal margin).

In the state of the vacuous stomach, and all the organs in the region being healthy, one can ascertain in the semi-lunar space a sharp tympanism with percussion, the absence of vocal vibrations by palpation and the absence of respiratory noise with auscultation.

Jacoud 1884

Percussion in Traube’s space is usually resonant, as it overlies the gastric bubble. Traube suggested that dullness to percussion over the space was a sign of pleural effusion; Parrino (1987) suggested that dullness to percussion may indicate splenomegaly. Dullness to percussion may also occur in postprandial patients. Sensitivity 0.62; Specificity 0.72 in detecting splenomegaly (Barkun 1989)


Traube phenomenon (1871)

In the presence of peritonitis caused by perforation of the appendix, even though pain and sensitivity to pressure may not be present in the right iliac fossa, pain may be produced by palpation in the left iliac fossa. [See also: Perman-Rovsing Sign (1904, 1907)]

Original
English

…weder die Schmerzen noch die krankhafte Empfindlichkeit gegen Druck sich in der Regio iliaca dextra am stärksten bemerklich machten. Es ist schwer, über die Ursache dieser Erscheinung Rechenschaft zu geben; denn wollten wir sie davon ableiten, dass der Entzündnngsheerd wegen seiner zu grossen Entfernung von der Bauchwand der Palpation in der Regio iliaca dextra nicht recht zugängig war, so durfte noch viel weniger ein Schmerz durch Druck auf die Regio iliaca sinistra hervorgerufen werden. Doch dem sei wie ihm wolle, jedenfalls sehen wir, dass eine von Durchbohrung des Wurmfortsatzes abhängige Peritonitis recht wohl vorhanden sein kann, ohne dass die Schmerzen und die krankhafte Empfindlichkeit gegen Druck ihren Hauptsitz in der Regio iliaca dextra zu haben brauchen.

Traube 1871; I: 360-361

…neither the pain nor abnormal sensitivity to pressure was present in the right iliac region. It is difficult to account for the cause of this phenomenon. It can be deduced that the inflammatory process was not quite accessible because it was at a greater distant from the abdominal wall and therefore could not be palpated in the right iliac fossa. Pain could be produced by palpatory pressure in the left iliac fossa. However, whatever the case may be, we can see that peritonitis caused by perforation of the appendix may be present, even though the pain and the morbid sensitivity to pressure may not present in the right iliac region.

Traube 1871; I: 360-361

Traube pulse (1872)

Traube coined the term ‘pulsus bigeminus’ in his classic paper presented to the Berlin Medical Society in 1871. Pulsus bigeminus is a variant form of pulsus alternans with alternate high and low character pulses, with the low pulses closer to the end of the previous high pulse than to the subsequent high pulse. Initially recorded on animals that had been curarized; then poisoned with potassium cyanide; and with both vagus nerves sectioned. In man, associated with severe left ventricular systolic impairment, and unfavourable outcomes.

The nature of the pulsus bigeminus may be said to be this: following every two pulses which originate in the aorta, a longer pause ensues. This phenomenon is differentiated from the pulsus dicroticus by the fact that in the latter there is only one contraction of the heart for every two beats of the pulse, while in pulsus bigeminus there are two contractions of the heart, which follow one another rapidly and are separated from the preceding and succeeding contractions by a longer pause.


Key Medical Attributions

Clinical Thermometry

Investigated the pathology of fever. In 1850, Traube introduced measurement of temperature as a routine clinical examination method along with Friedrich Wilhelm Felix von Bärensprung (1822-1864), head of the department of syphilitic diseases at the Charité. In 1852 Traube produced the first graphic presentation of a fever course with simultaneous recording of pulse and respiratory frequency.


Controversies

Traube died aged 58 following repeated bouts of ‘angina pectoris’. He described/diagnosed his own perimortem condition as; “Hypertrophy and dilatation of both ventricles with arteriosclerosis and coronary sclerosis with partial fatty degeneration of the myocardia.“
