Abstract

The application of carbon dioxide anesthesia to fish has been studied in order to find a method of transport of live fish. In the continuation of this study, the levels of arterial PaO2, PaCO2 and pH were examined in carp anesthetized with carbon dioxide. In the initial stage of the anesthesia, both PaO2 and PaCO2 increased. In the following stage, PaCO2 gradually decreased. An increase or decrease in PaO2 seems to depend on the levels of PaCO2 during anesthesia. On the other hand, ECG (electrocardiogram) profiles of anesthetized carp indicate that a gradual increase in R-R interval is coupled with a gradual decline of the opercular rate.

摘要

为了找到一种活鱼运输的方法，人们对二氧化碳麻醉在鱼类中的应用进行了研究。在这项研究的后续阶段，对用二氧化碳麻醉的鲤鱼的动脉血氧分压（PaO2）、动脉血二氧化碳分压（PaCO2）和pH值水平进行了检测。在麻醉初期，PaO2和PaCO2均升高。在随后的阶段，PaCO2逐渐下降。PaO2的升高或降低似乎取决于麻醉期间的PaCO2水平。另一方面，麻醉鲤鱼的心电图（ECG）显示，R-R间期逐渐增加，同时鳃盖运动频率逐渐下降。
