    Description / Table of Contents: Summary Neurological respiratory insufficiency may be the primary cause of admission to an intensive care unit or may develop during care in an intensive care ward. Severe respiratory insufficiency due to nervous system causes either involves a lack of central drive or weakness of the respiration muscles. The former are induced by a wide variety of encephalopathies and the latter by diseases of anterior horn cells, peripheral nerve, the neuromuscular junction, or muscles of the chest wall or diaphragm. In an intensive care unit, it is often not possible clinically to determine whether there is a lack of central drive or a neuromuscular problem. It is now possible by electrophysiological methods to pinpoint the site of nervous system cause of respiratory insufficiency. This review will describe the various electrophysiological techniques currently available and describe how they have been successfully applied in investigating some conditions that cause severe respiratory failure.
    Notes: Zusammenfassung Die neurologisch bedingte Atemmuskelinsuffizienz kann sowohl Ursache zur Aufnahme an der Intensivstation sein als auch sekundär im Rahmen der Intensivtherapie auftreten. Das Spektrum neurologisch bedingter Atemstörungen umfaßt eine Vielzahl von Erkrankungen des zentralen und peripheren Nervensystems. Die klinische Differenzierung der Genese neurologischer Atemstörungen ist insbesondere bei Patienten der Intensivstation häufig nicht möglich. Neu entwickelte elektrophysiologische Techniken erlauben eine präzise Lokalisationsdiagnostik der Atemstörung, welche für das Management dieser Patienten nützlich ist. In dieser Übersicht werden die elektrophysiologischen Untersuchungen zur Diagnostik der Atemmuskelfunktion und deren Einsatz bei neurologisch bedingten Atemstörungen vorgestellt.

    Notes: Abstract Single-photon emission tomography (SPET) was performed during electrical median nerve stimulation and used to detect focal neuronal activation in the somatosensory pathways. Intravenously administered technetium-99m ethyl cysteinate dimer (ECD) was used as a blood flow tracer to obtain baseline and activated images in each of three subjects. After image registration, baseline images were compared voxel by voxel with the activation images. In addition, the mean summation of the activated-state images of the subjects was compared with the mean summation of the baseline-state images of ten normal subjects. Discrete brain regions occupying 0.9%–1.6% of total brain volume showed an increase in signal from 33.6% to 35.0%. For further anatomical localization of regional increases in signal, the MRI scan of each subject was registered and superimposed on the activated-state SPET image. This method may be used to localize lesions in various disorders of the central nervous system.
