[Removable electromagnetic transducer for the study of cardiac minute volume in the conscious dog]

The study aimed at evaluating the reliability of a new type of aortic flow probes to be used in conscious dogs and easy to be removed without a second surgical intervention, 48-72 hours after they have been implanted. The probes, which have been made in the Department of Human Physiology of the University of Turin, are light and thin enough to be cronically implanted around the aorta without removing the fat which surrounds the artery, and to be taken away without injuring the tissues. The records obtained 24 and 48 hours after they have been positioned, demonstrate the reliability of the probes. Histological examination of the aorta has not evidenced any tissue reaction.
