[Circulatory pattern under electro-stimulation-analgesia and neurolept-anaesthesia in the same patient. A comparative...

The present paper reports a comparative study on circulatory conditions of patients who underwent both electro-stimulation- and neurolept anaesthesia. Investigations were carried out in 20 patients who had operations on the retina or vitreous body, either under neurolept or electro-stimulation anaesthesia, and who had to undergo a second of those, so that both types of anaesthesia were administered in each patient. 50% of the patients were showing polymorbidity which is often observed in elderly persons; 5 of the cases were patients suffering from hypertonia which had previously been treated unsatisfactory. As measure for judging the circulatory conditions under either anaesthetic method, the plain measurable values of systolic and diastolic pressure and heart rate were registered. A statistical evaluation of the anaesthetic records was carried out with special consideration of circulatory stability and each method of anaesthesia in the individual group of patients. Concerning circulatory changes, significant variations on 1%- level were found.
