[Changes of pressure within the middle ear during various kinds of anaesthesia (author's transl)]

Measurements of the middle ear pressure were taken during anaesthesia in 18 patients. Using nitrous oxide the middle ear pressure increased considerably. Other anaesthetics (i.e. anaesthesia with neuroleptics) did not show this remarkable change in middle ear pressure. To avoid complications by middle ear operations (tympanoplasty) we combine both methods of anaesthesia.
