"Today, we are going to demonstrate an appendectomy on an experimental rabbit."
Li Ang lifted a white-furred rabbit from its iron cage and placed it on the operating table at the edge of the classroom. The students all stood up from their seats and gathered around the table to observe.
"First, position the experimental rabbit on the operating table, secure its limbs, then pluck the down from its ears." Li Ang explained his actions. "A rabbit's ears are very thin. Once the down is removed, you can see the slender, curved marginal ear vein. This is the most convenient place for an injection on a rabbit. Before administering the anesthetic, lightly massage the ear and apply pressure at its base to engorge the marginal ear vein, causing it to bulge. Dr. Qiu, I'll go wash my hands; you can administer the anesthetic."
