Benzocaine hydrochloride is the hydrochloride form of the local anesthetic Benzocaine. Its pharmacological action is the same as that of Benzocaine and its anesthetic effect is weaker than that of procaine.Local absorption is slow and long-lasting.Because insoluble in water, can not be used as infiltration anesthesia, analgesic, antipruritic effect, drugs usually made of powder or oil paste, clinical for the treatment of wounds, ulcers, burns, skin abrasions and hemorrhoids, etc. Benzocaine also known as aminobenzoate ethyl ester, sinecetine.The precipitates from water are colorless or white rhombic needle-like crystals or crystalline powder, and the precipitates from ether are square crystals.Odorless.Has a bitter taste.The molecular weight is 165.19.Melting point is 92 ℃.Boiling point 310℃, 183 ~ 184℃(1.87×103Pa).Insoluble in water, soluble in ethanol, ether and chloroform, but also soluble in almond oil, olive oil and dilute acids.Stable in the air. Taking p-nitrotoluene as raw material, in sulfuric acid, with sodium dichromate oxidation, p-nitrobenzoic acid, ethanol esterification reaction, separation, p- nitrobenzoic acid ethyl ester in acetic acid solution, iron powder at 85 ~ 95℃ reduction, benzocaine crude product.After separation, washing with water, and then recrystallization in ethanol refining.

At room temperature, procaine hydrochloride is a fine white needle-like crystal or crystalline powder, odorless, slightly bitter and tingling, easily soluble in water, soluble in ethanol, slightly soluble in chloroform, almost insoluble in ether.In the structure of procaine hydrochloride, the ester bond can be hydrolyzed to form p-aminobenzoic acid and diethylaminoethanol. Under certain conditions, p-aminobenzoic acid can be further decarboxylated to form toxic aniline.The structure of procaine hydrochloride has aromatic amino group, which is easy to oxidize and change color. The oxidation and change color can be accelerated by pH value, temperature, ultraviolet light, oxygen and metal ions. Hydrochloric acid procaine is a local anesthetic, can temporarily block the conduction of nerve fibers and has an anesthetic effect, strong effect, low toxicity, and no addiction, but on the skin, mucous membrane penetration is weak, not suitable for surface anesthesia, clinical mainly used for infiltration, spine and conduction anesthesia. The aqueous solution of this product is stable in pH3.0 ~ 5.0.Therefore, when preparing procaine hydrochloride injection, it is generally necessary to add acid to adjust pH3.3 ~ 5.5, and strictly control the sterilization temperature and time. It is advisable to circulate steam for sterilization at 100℃ for 30min, and attention should be paid to shading and airtight preservation.This product structure of the aromatic amino in dilute hydrochloric acid, with sodium nitrite to generate diazo salt, coupled with basic β-naphthol reaction, the generation of scarlet azo compounds.

In the past few decades, polypectomy has been very helpful in reducing the incidence and mortality of cancer, and has become the cornerstone of the prevention of cancers occured in digestive tract in the future. Endoscopic polypectomy includes high-frequency electrocoagulation, Esophageal polypectomy, nylon wire ligation, argon ion coagulation, and microwave cauterization. Among them, high-frequency electrocoagulation resection is currently the most widely used treatment method. Advantages of Polypectomy With ESD knifes, it can achieve curative resection of superficial gastrointestinal lesions Compared with traditional EMR, it has the advantage of being able to excise the lesion larger than 2cm in diameter in one piece, thereby avoiding local recurrence Effectively prevent gastrointestinal cancer Less bleeding and low risk of perforation Operation Steps of Polypectomy Operation Steps of Polypectomy As for polypectomy, the high-frequency electrocoagulation resection can be adopted. Take the high-frequency electrocoagulation resection for example, its general steps of are as follows: The Sterile Hot Snare covers the tumor and electrocautes, after it was cut off, use biopsy forceps or grasping forceps to clamp it and take out the specimen through the gastroscope. The specimen is sent for pathological examination. Micro-Tech is a professional gastroenterology products supplier. We provide EUS, Hemostasis, eus gastroscopy, eus endoscopic ultrasonography, lung endoscopy and so on. Want to know about micro tech china? Please contact us.
