課本整段字句:
The fourth means of promoting hemostasis is by placing vasoconstrictive substances such as epinephrine in the wound or by applying procoagulants such as commercial thrombin or collagen on the wound.
Epinephrine serves as a vasoconstrictor most effectively when placed in the site of desired vasoconstriction at least 7 minutes before surgery begins. Epinephrine is ineffective for promoting local hemostasis if administered after bleeding has started.
