BILANMA” is a new type of oral special anesthetic put into production by French company BILAN in recent years. “BILANMA” is the trade name, and its main components are: 4% Articaine hydrochloride and 1/100,000 epinephrine. Atiocaine and lidocaine belong to the same amide-type local anesthetics, through the clinical application, it has shown very obvious advantages, so it is soon promoted and used in the domestic dental hospitals and general hospital stomatology departments. As a new type of oral special anesthetic, “BILANMA” has particularly strong penetration, so it is generally used only for submucosal infiltration anesthesia in oral treatment, which obviously simplifies the operation and thus reduces the complications that may occur in conventional conduction block anesthesia, such as hematoma and infection. The special injection needle is very thin, only 0.3-0.5 mm, and the injection is painless, so it can be called a veritable “painless anesthesia”. It reduces the pain and fear of patients in oral treatment and is very popular among patients. Because of its strong anesthetic power, long duration, less bleeding, no clinical allergic reactions and other obvious adverse reactions, so it is the safest and most effective local anesthetic in dentistry. The local injection anesthetic “BILANMA” produced by France BILAN Company has been widely used in many dental hospitals and stomatology departments of major general hospitals in China. 1.Bilanoma is the trade name, its main components are: ativacaine hydrochloride 4%, epinephrine: 1:100,000. Articaine and lidocaine belong to the same amide class of local injection anesthetics. 2.Biram anesthesia has the characteristics of fast onset of anesthesia (about 2-3 min), strong permeability to tissues (the conventional submucosal infiltration method can be used for tooth extraction, tooth preparation and endodontic treatment of maxillary and mandibular posterior teeth), high anesthetic efficacy (a small injection can achieve the ideal anesthetic effect), and small toxic side effects. 3.If the patient has no history of allergy to lidocaine, then, he is certainly not allergic to atticaine. There is no need to do skin test for routine application of Bilaamma. 4.Bilanoma contains epinephrine 1:100,000, so it should be used with caution for hypertensive patients and the elderly, but not prohibited. The doctor can decide according to the actual situation of the user. In addition, the conventional dosage of Bilamat is small and generally adopts mucosal local infiltration injection method, so the actual amount of epinephrine injected into the body is very small. However, attention should still be paid to the slow speed of injection, with each injection taking about 1 min. 5, the use of Bilamat is usually only mucosal local infiltration injection method can be used, in the treatment of multiple teeth using a needle conduction block anesthesia method is simpler. But at this time, attention should be paid to the return of blood aspiration, to avoid the injection of Bilan marijuana into the blood vessels. Injecting speed, it takes about 1 min for each Bilaam. 6, when the mandibular posterior teeth are extracted, only the mucosal local infiltration injection method can also achieve the ideal anesthetic effect. It should be noted that clinically, there are individual patients who may experience incomplete filling of the extraction sulcus after tooth extraction, which is due to the effect of epinephrine. In this case, in order to avoid the emergence of dry sulcus, the extraction wound should be scratched after extraction to make the extraction sulcus completely filled with blood and then compressed to stop the bleeding. 7.Imported Bilamat has been inspected and qualified by the domestic drug testing institute. When purchasing, please ask the sales unit for the inspection report and the “Certificate of Registration of Imported Drugs”. 8.The specification of Bilamat is 1.7ml/pc, 50pcs/tube. Routinely, 0.8 ml for single tooth and 1.5-1.7 ml for multiple teeth can be injected locally. 9.According to the regulations of the State Price Bureau, the sales price of Bilan Ma is: retail price 455 Yuan/tube (i.e. 9.1 Yuan/pc), wholesale price 409.6 Yuan/tube (i.e. 8.192 Yuan/pc).
