[Bulbar hypertension in eye surgery]

Perfusion althesin, pentazocin and an association of halothane was used in more than 500 eye operations. A number of parameters (left humerus arterial pressure, heart rate, CVP, IOT) were measured and assesed statistically in 21 selected patients and a pathogenetic interpretation of observed bulbar hypotonia attempted. The important bulbar hypotonizing action brought on by this anaesthetic procedure, and the favourable course of surgery with the technique are confirmed.
