[Acid-base equilibrium and blood and cerebrospinal fluid oxygenation during angiography and pneumoencephalography]

Acid-base equilibrium changes were analyzed in the blood and cerebrospinal fluid (CSF) by gasometric methods in 86 patients during cerebral angiography and 26 during pneumoencephalography. The observed changes of the parameters of this equilibrium indicate the usefulness of this analysis before diagnostic procedures for avoiding complications developing in patients with disturbances or acid-base equilibrium.
