Abstract

Close
- The effects of 1 min exposure to 80% CO2 inhalation was studied in rats under light general anaesthesia with N2O. It was found that 80% CO2 gave a rapid slowing of the EEG as well as a rapid decrease of the amplitude of cortical somatosensory evoked potentials. Only minor influences upon the blood pressure and heart rate were seen. The changes were found to be transient and most of the EEG effects had disappeared about 2-3 min following the end of the CO2 exposure. The findings are related to current procedures for preslaughter anaesthesia in swine using 80% CO2. The present experiments show that 80% CO2 rapidly induces an interruption of afferent sensory transmission to the cortex as well as slowing of the EEG. Both findings indicate that 80% CO2 is an effective agent for inducing adequate anaesthesia for slaughter procedures. However, the transient nature of the CO2 effects upon the central nervous system revealed here has to be taken into account to optimize the slaughter house procedures.
