| pubmed-article:8205951 | pubmed:abstractText | Introduction of anaesthesia with CO2/O2 (60% to 40%) is possible within 90 and 120 seconds. There are moderate to excessive excitations occurring as part of state II of anaesthesia. Anaesthesia (during castration) in CO2/O2-atmosphere produces excellent analgesia and relaxation. The duration of castration surgery is much shorter under CO2-anaesthesia than without anaesthesia. Blood cortisol levels are significantly higher after castration without CO2-anaesthesia. About 5 minutes after CO2/O2-anaesthesia and castration surgery, piglets are already awake and standing. | lld:pubmed |
