A method and solution for perioperatively inhibiting tumor cell adhesion and a variety of pain and inflammation processes at wounds from general surgical procedures including oral/dental procedures. The solution preferably includes at least one anti-tumor cell adhesion agent and multiple 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 preemptive inhibition of pain and while avoiding undesirable side effects associated with oral, intramuscular, subcutaneous or intravenous application of larger doses of the agents. One preferred solution to inhibit tumor cell adhesion, pain and inflammation includes at least one anti-tumor cell adhesion agent, a serotonin2 antagonist, a serotonin3 antagonist, a histamine antagonist, a serotonin agonist, a cyclooxygenase inhibitor, a neurokininl antagonist, a neurokinin2 antagonist, a purinoceptor antagonist, an ATP-sensitive potassium channel opener, a calcium channel antagonist, a bradykininl antagonist, a bradykinin2 antagonist and a µ-opioid agonist.

L'invention concerne une méthode et une solution permettant d'inhiber de manière périopératoire une adhésion de cellules tumorales et une palette de douleurs et de processus inflammatoires au niveau de blessures liées à des interventions chirurgicales générales, notamment des interventions orales/dentaires. La solution comprend, de préférence, au moins un agent anti-adhésion de cellules tumorales et plusieurs agents d'inhibition de douleurs et d'inflammations dans une concentration diluée dans un véhicule physiologique, tel qu'une solution saline ou de Ringer lactée. La solution est appliquée par irrigation continue d'une blessure pendant une intervention chirurgicale aux fins d'inhibition préventive de douleurs et de manière à éviter simultanément des effets secondaires non souhaités associés à l'application orale, intramusculaire, sous-cutanée ou intraveineuse de doses importantes des agents. Une solution préférée permettant d'inhiber l'adhésion de cellules tumorales, des douleurs et des inflammations comprend au moins un agent anti-adhésion de cellules tumorales, un antagoniste de la sérotonine¿2?, un antagoniste de la sérotonine¿3?, un antagoniste de l'histamine, un agoniste de la sérotonine, un inhibiteur de la cyclo-oxygénase, un antagoniste de la neurokinine¿l?, un antagoniste de la neurokinine¿2?, un antagoniste du purinocepteur, un ouvreur des canaux potassiques sensibles à ATP, un antagoniste du canal calcique, un antagoniste de la bradykinine¿l?, un antagoniste de la bradykinine¿2? et un agoniste µ-opioïde.
