Toute intervention chirurgicale dans la bouche de nos patients est douloureuse. Il est de notre devoir, en tant que v\u00e9t\u00e9rinaires, d’utiliser toutes les ressources que la m\u00e9decine moderne met \u00e0 notre disposition pour \u00e9viter la douleur et la souffrance.<\/p>\n

Les blocs anesth\u00e9siques sont des techniques d’anesth\u00e9sie r\u00e9gionale qui emp\u00eachent la propagation du stimulus nociceptif aff\u00e9rent des nerfs p\u00e9riph\u00e9riques vers le syst\u00e8me nerveux central, bloquant ainsi la sensation de douleur.<\/p>\n

Il est n\u00e9cessaire de garder \u00e0 l’esprit que l’animal n’a pas besoin d’\u00eatre conscient pour que cette sensation se produise. En d’autres termes, l’anesth\u00e9sie g\u00e9n\u00e9rale d’un patient ne dispense pas le clinicien d’appliquer des techniques analg\u00e9siques.<\/p>\n

Le nerf maxillaire est l’une des branches du nerf trijumeau (V) qui comprend des fibres aff\u00e9rentes, donc sensitives. Il innerve la r\u00e9gion maxillaire ipsilat\u00e9rale.<\/p>\n

Le nerf maxillaire \u00e9merge par le foramen rond et longe la base de l’orbite \u00e0 c\u00f4t\u00e9 de la paroi de la fosse pt\u00e9rygopalatine. Rostralement, il p\u00e9n\u00e8tre dans le canal infra-orbitaire par le foramen maxillaire. C’est dans ce canal qu’il se ramifie vers les pr\u00e9molaires et les molaires de la r\u00e9gion, ainsi que vers la canine et l’incisive ipsilat\u00e9rale via le canal incisif-canin. Le blocage de ce nerf emp\u00eache la propagation du signal nociceptif de la r\u00e9gion maxillaire ipsilat\u00e9rale, ce qui nous permet de r\u00e9aliser des interventions chirurgicales indolores dans cette r\u00e9gion.<\/p>\n

La technique repose sur l’inoculation d’un anesth\u00e9sique local dans la fosse pt\u00e9rygopalatine. La fosse pt\u00e9rygopalatine elle-m\u00eame sert de point de r\u00e9f\u00e9rence. Elle est identifi\u00e9e par palpation, la muqueuse buccale pouvant \u00eatre d\u00e9prim\u00e9e juste au niveau de la deuxi\u00e8me molaire maxillaire.<\/p>\n

L’aiguille doit \u00eatre ins\u00e9r\u00e9e \u00e0 quelques millim\u00e8tres dans la fosse et doit toujours \u00eatre aspir\u00e9e avant l’inoculation du m\u00e9dicament anesth\u00e9sique afin d’\u00e9viter l’administration intravasculaire du m\u00e9dicament. Apr\u00e8s l’administration, il convient de respecter le d\u00e9lai sp\u00e9cifique de l’anesth\u00e9sique local utilis\u00e9 avant qu’un stimulus nociceptif ne se produise.<\/p>\n
