[Clinical experience of Ethrane inhalation anaesthesia compared with halothane inhalation anaesthesia in dogs (author's transl)].
Anaesthesia was carried out in fourteen cases as part of the present study, ethrane being used in eight and halothane in six cases. Each group included an experimental dog in which surgery was not performed. The others were patients which had to undergo a surgical procedure. In addition to clinical impressions, the following parameters were recorded: the pulse and heart rates, the electrocardiogram, the systolic pressure and the capnogram. In view of the small number of and marked variation in patients, only cautious conclusions could be drawn. Attention is drawn to the fact that cardiovascular complications may occur when large doses of the anaesthestics are administered. These large doses were constantly required to maintain a sufficiently deep anaesthesia when ethrane was used. The amount of ethrane utilized therefore was definitely larger than was that of halothane. Ethrane had the advantage that recovery from anaesthesia was mor rapid and smoother. Personal experience showed that satisfactory anaesthesia may be produced by either anaesthetic. Secondary considerations may therefore be an important factor in making a choice between the two agents.
