Background It remains unknown how single‐shot anesthesia influences physical parameters, especially respiratory function and blood oxygen level of common marmosets ( Callithrix jacchus ) which came to be used for laboratory research. Methods We measured blood oxygen levels, both before and after oxygenation, in 13 common marmosets under two single‐shot anesthesia conditions: ketamine/xylazine/atropine and alphaxalone. Results and Conclusions We found that SpO 2 values decreased to about 80% in the ketamine/xylazine/atropine protocol and fell just below 90% in the alphaxalone protocol. We observed a clear decrease in PaO 2 values under the anesthetized condition compared to the awake condition. Our data indicate that single‐shot anesthesia may cause hypoxemia in marmosets. Previous studies on other non‐human primate have reported no SpO 2 decrease and hypoxemia; thus, our experiment suggests that marmosets may have a more fragile respiratory system and require intensive veterinary care during anesthesia.
