[Hazards and complications of pneumoencephalography in children].

In a series of 1334 consecutive pneumoencephalographies in children 0-15 years, there were 2 deaths, 3 severe apneas and 1 pneumomediastinum. Respiratory insufficiency, due to contention of the patient with resulting impairment of the motion of thoracic muscles was an important mechanism and pneumoencephalography is contra-indicated in children with respiratory difficulties prior to the examination. In 90 consecutive patients submitted to pneymoencephalography CSF changes and fundus oculi abnormalities were studied prospectively. Aseptic meningitis of a mild degree is common following the examination, whereas significant meningeal haemorrhage is rare. Haemorrhages in the fundi were noted in 10% of the patients. The general tolerance of the examination was good.
