[Anesthesia for nuclear magnetic resonance tomography (NMR)]. / Anaesthesie bei der Kernspintomographie (KST).

The NMR-Tomography as a new imaging device is still in the experimental stage for clinical use. It has distinct advantages in comparison to other conventional methods especially when considering special indications and clinical considerations. In some cases NMR-Tomography can only be carried out when a patient is under general anesthesia. This anesthesia must be performed in accordance with the basic nature of this imaging method, i.e. one always has to remember that no ferromagnetic material can be used in the vicinity of the apparatus. With our described method a certain and safe performance of general anesthesia for NMR-Tomography is possible.

[Problems in laser surgery and anesthesia]. / Zur Problematik von Laserchirurgie und Anaesthesie.

Accidental thermal damage in case of explosion and fire caused by laser-surgery is a well-known problem and still not solved. A combination of laser beam, oxygen and inflammable substances are only one aspect. A main problem is the venturi-effect resulting from artificial ventilation under anaesthesia. An incidental observation during one case of endotracheal tube-fire led to some fundamental considerations. With a modified PEEP-ventilation hazard can not be prevented, but limited in its complications.
