07口腔局部麻醉（07 partial oral anesthesia） A definition Oral local anesthesia: refers to the use of drugs temporarily blocking a certain parts of the body sensory nerve conduction, that part of the pain disappeared, to undergo surgery in completely painless cases. Two, the commonly used anesthetic drugs 1, Liddle Kain: amides, quick effect, wide dispersion, strong penetrability, no stimulation of the organization 2, procaine esters, side effects of small, weak penetration, not suitable for surface anesthesia 3, Bbu Be Kain: amide, 4, tetracaine esters, high toxicity, mainly for mucosal surface anesthesia, 1~3 minutes of onset, for 20~40 minutes. 5, Compound Articaine Hydrochloride Injection: Primacaine, mucosal infiltration of local injection, but also can be used for anesthesia Three, the oral local anesthesia method 1, surface anesthesia: anesthetic injection in the operation area or coating surface, and the anesthetic absorbed peripheral nerve palsy, in order to achieve the effect of pain disappeared. For incision and drainage of superficial submucosal abscess, loosening the primary or permanent removal, tongue, soft palate, pharynx, surface anesthesia before tracheal intubation 2, anesthesia is a local anesthetic injection in the organization, to block the application site of nerve conduction anesthesia analgesia (Pichugin injection, supraperiosteal infiltration method, periodontal membrane injection) For oral and maxillofacial surgery and within the scope of the teeth and alveolar surgery 3: Department of anesthesia, the anesthesia was injected into the nerve around 1000 Jing, the conduction is blocked, make area of the nerve, all lose pain. General anesthesia Regional anesthesia indication sign note injection injection method After the alveolar nerve block anesthesia (tuberosity injection) In addition to the first molars and the ipsilateral molars, alveolar bone, periosteum, buccal gingival. Maxillary molar extraction; corresponding buccal gingival mucosa, and maxil
