Wolfram von Eschenbach was a medieval German poet who wrote Parzival, an epic poem that includes descriptions of battlefield medicine in the 13th century. The poem follows the stories of Parzival and Gawain across 16 books and depicts medical treatments of the time. Some key medical topics covered include hemothorax, empyema, tension pneumothorax, the mechanics of breathing, and chest tube insertion procedures.
12. Gas Exchange in Human Breathing
Negative Pressure Breathing: Change of pressure
within the lung cavity relative to the air pressure
outside.
The exchange of oxygen and carbon dioxide
between the air and the blood in the lungs.
13. Although fractured ribs are not necessary for tension pneumothorax to occur, they are
often associated with disruption of either the visceral or parietal pleura.

often fractured posteriorly (black arrows). If multiple rib fractures occur
along the mid-lateral (red arrows) or anterior chest wall (blue arrows), a flail
chest (dotted black lines) may result.
18. Tube Thorocostamy:
Palpation of the selected intercostal space
and the superior margin of its inferior rib:
A closed and locked Kelly clamp is used to enter the
chest wall into the pleural cavity. Make sure to guide
the clamp over the upper margin of the rib:
19. Tube Thoracostamy:
A finger is used to palpate the tract and feel for
adhesions before insertion of the chest tube:
The proximal end of the chest tube is held with a Kelly
clamp that is used to guide the chest tube through the
tract. The distal end of the chest tube should always be
clamped until it is connected to the drainage device:
20. Tube Thoracostamy:
Connection of the chest tube to
a drainage system:
A 0 or 1-0 silk or nylon suture is used
to secure the chest tube to the skin:
21. Apply petrolatum (eg, Vaseline)
gauze over the skin incision:
Apply support gauze dressing around the
chest tube and secure it to the chest wall
with 4-in adhesive tape:
