Abstract

Graphic abstract

Background: We hypothesized that the expression of exosomes under general anaesthesia with an inhalational anaesthetic agent would be changed. The study was designed to confirm the effect of general anesthesia with an inhalational anaesthetic agent on the expression of exosomes in rats.

Methods: After intraperitoneal administration for the mixture of ketamine and xylazine, tracheal intubation was performed. Just before the connection to ventilator, Control group and Anaesthesia group, according to anaesthesia with isoflurane, were allocated. The expressions of exosomes were checked in bronchoalveolar lavage (BAL), the blood and the tissues from the lung and the brain. Cytokines in the blood were also assessed.

Results: The expressions of cluster of differentiation (CD)63 and CD81 as markers for the exosomes in the blood was increased after anaesthesia with isoflurane (CD63, 0.078 ± 0.057 % in Control group vs. 0.180 ± 0.036 % in Anaesthesia group, p = 0.02; CD81, 0.028 ± 0.034 % in Control group vs. 0.245 ± 0.054 % in Anaesthesia group, p < 0.01). However, the increased expression of them were not checked in BAL, and the tissues from the lung and the brain. The cytokines in the blood did not show any significant difference before and after anaesthesia with isoflurane.

Conclusion: General anaesthesia with an inhalational anaesthetic agent increased the expression of exosomes in the blood. However, the change was limited in the blood, not the alveoli and the brain.
