Sauerbruch chamber

First Operating chamber used by Mikulicz and Sauerbruch

A Sauerbruch chamber, is a hermetically sealed chamber where surgical operations of the thorax are carried out, preventing complication by elevating or reducing air pressure.^[1]

History

Until the beginning of this century Thoracic surgery did not seem possible because a reduced-pressure-atmosphere prevails in the body cavity, hence the lungs collapse when the body cavity is opened resulting in Pneumothorax, causing death. Surgeon Ferdinand Sauerbruch realized this problem, concluding that altered external pressure might render Thoracic surgery possible. He issued the construction of a glas-chamber for experiments.

First Experiments on animals

After a series of tests on rabbits and dogs, Sauerbruch proudly presented his apparatus to Felix von Mikulicz-Radecki, the head of his clinic at the University of Breslau - but the presentation failed because of material error. Mikulicz-Radecki grew disappointed and discharged Sauerbruch from his hospital. But after continuing his research in a private hospital, Sauerbruch contacted Mikulicz-Radecki again and gained his approval for human trials.^[2]

Operation on Humans

On 6 April 1904 Sauerbruch and Prof. Mikulicz presented an operation on the open thorax in a vacuum chamber, growing famous after succeeding, although the first patien an old woman soon died. Nevertheless the second operation, performed on an opera singer, proved Sauerbruch´s methods viable.^[3]

The chamber was soon called "Sauerbruch chamber".^[4][5] Sauerbruch went to Greifswald and Marburg after the death of Professor Mikulicz and used this opportunities to further develop his method. As head of clinics in Zurich and later Munich, he built his final vacuum chamber after the First World War.

Function

In the Sauerbruch Chamber the patient's head is elided, sticking out of the glas-chamber. The surgical team works inside the chamber that hermetically seales the body of the patient. To start the operation on the thorax a vacuum of 1/10 Bar is generated, preventing the patient's lungs from colapsing upon opening the thorax.

Replacement

Since the introduction of Tracheal intubation, this effect is achieved by positive pressure ventilation. In the treatment of esophagus cancer, tumors of the mediastinum, or lung tumors, an overpressure in the ventilation of the operated is generated, a process which is more practical and more successful.
