Abstract:
A method and solution for perioperatively inhibiting a variety of pain and inflammation processes during arthroscopic procedures. The solution preferably includes a vasoconstrictor that demonstrates substantial agonist activity at alpha adrenergic receptors and that is selected for peripheral (local) vasoconstriction and one or more additional pain and inflammation inhibitory agents at dilute concentration in a physiologic carrier, such as saline or lactated Ringer's solution. The solution is applied by continuous irrigation of a wound during a surgical procedure for peripheral vasoconstriction and inhibition of pain and/or inflammation while avoiding undesirable side effects associated with systemic application of larger doses of the agents.
