[Bilateral diaphragmatic paralysis, the cause of acute insufficiency in chronic obstructive bronchopathy. The value of nasal mechanical ventilation].
A 57 year old man with chronic bronchitis sought a consultation for dyspnoea at rest associated with an absolute inability to lie flat. Examination revealed paradoxical respiration and respiratory function testing revealed a mixed ventilation disturbance, which was predominantly obstructive and was aggravated in the dorsal decubitus position. Radiology revealed bilateral diaphragmatic paralysis, which was confirmed on measurement of transdiaphragmatic pressure. The patient benefited from assisted ventilation by the nasal route with an excellent result in both the short and the medium term. Investigation into the cause was negative, in particular there was no evidence of any neuromuscular abnormality. This case recalls the role of the diaphragm in acute respiratory failure and shows the value of mechanical ventilation by the nasal route in the treatment of certain types of diaphragmatic paralysis.
