Abstract
The effects were studied of a standardised general anaesthesia on mean arterial blood pressure, central venous pressure, blood gas values and the course of cataract operations. The material consisted of 20 unselected senile cataract operations, the mean age of the patients being 71.3 years. The arterial blood pressure was continuously checked, using an intra-arterial cannula. In order to avoid vitreous loss, the blood pressure was successfully kept optimally low during the extraction of the lens. No vitreous problems were noted. The oxygenation and ventilation of the patients were sufficient during anaesthesia and immediately postoperatively.
