[Perilymphatic perfusion of the cochlea (guinea pig) with fluorocarbon emulsion (author's transl)].

Because oxygen is at least ten times as soluble in fluorocarbon liquids as in plasma or saline, we investigated the principle possibility of perilymphatic perfusion of the cochlea with perfluortributylamin. Our experiments show that fluorocarbons in spite of the excellent O2-solubility in it are not suitable for the perilymphatic perfusion due to their physical properties (density 1.91 g/ml, non-solubility in water, necessity and difficulties of emulsification).
