PT journal article

AB As an anesthetic for long-term anesthesia, two concentrations of CO2 were used: a high concentration (PCO2 = 200, 225 or 250 mm Hg) for inducing anesthesia quickly and a low concentration (PCO2 = 100 mg Hg or 125 mm Hg) for maintaining anesthesia. Adult carp were kept in water containing the high or low concentration of CO2 for a total of 10 h; the duration of each treatment was 15 min or 30 min at the high concentration and 1 h or 9.5 h at the low concentration. The time needed for the induction of anesthesia was shortened by the use of the high partial pressure of CO2 (PCO2 = 250 mm Hg). The carp could be anesthetized or sedated for 10 h, using PCO2 = 250 mm Hg as the high concentration and PCO2 = 100 mm Hg as the low concentration of CO2.
