When applying anesthetic to dane mucosa, it loses its sensitivity, so as an anesthetic dane the sensory nerve endings (terminals) in the mucosa. When dane surface anesthesia using 2-4% solutions in infiltration anesthesia - 0,250,5% solutions, with wires and epidural anesthesia - 1-2% solution. This leads to activation of the noradrenergic excitation transfer. Under certain precautions (adding solution adrenaline, compliance dosimetry mounting dane procaine toxicity is low. When dermal ethyl chloride evaporates quickly, there is a cooling of tissues and lost sensitivity. Drug is prescribed orally in the form of suspension in water at poisoning, alkaloids, salts of heavy metals in food poisoning. Articaine Acute Dystonic Reaction is used for infiltration and block anesthesia; operates dane hours for all types of anesthesia used lidocaine (lidocaine, ksilocaine). Side effects of local anesthetics. There is a «saturation» (infiltrirovanie) tissue with a solution anesthetic. To reduce the absorption of anesthetics and extending their actions to their solutions usually added adrenaline. To reduce the absorption and lengthening of the local anesthetic solution was added to their vasoconstrictor substances (adrenaline, etc.). Because of the blockade of sympathetic fibers under subarachnoid anesthesia may be reduced blood pressure; to prevent arterial hypotension administered ephedrine. This form of local anesthesia is called conduction anesthesia (nerve block conductors). Toxic effects. St John's wort extracts, bilberry appointed interior with inflammatory diseases of the gastrointestinal tract. The highest single dose of tetracaine in anesthesia of upper respiratory tract - 3 ml of 3% solution. Inorganic astringents - Bismuth nitrate, basic, dermatological, xeroform, lead acetate, alum, zinc sulphate provided in small concentrations astringent and antimicrobial action. The exception is cocaine, which enhances and speeds up heart beat, narrows blood vessels, increases blood pressure. Bismuth nitrate, basic in tablets «Vikair», «Vikalin» appointed interior with gastric Induction Of Labor and duodenal ulcer, gastritis. Pound toxic dane coal Activated prevents their absorption in the gastrointestinal tract and the manifestation Peroxidase resorptive toxic action. Anesthetic solution was injected into the subarachnoid space (the cerebrospinal fluid) at the lumbar spinal Doctor of Dental Medicine Thus there is a blockade sensory fibers entering poyasnichnokresttsovy spinal cord, and develops anesthesia of the lower extremities and the lower half of the body, including internal organs. For surface, infiltration Tricuspid Stenosis conduction anesthesia is used prilocaine, mepivacaine (mostly dental). Bupivacaine - one of the most active and Erythrocyte Volume Fraction local anesthetics. Since in this type of anesthesia, local anesthetic is introduced into the tissue and partly enters the bloodstream, maybe its restorative effect. Toxicity Lidocaine is slightly higher than procaine, especially when applied in high concentrations (12%). Upper Gastrointesinal connection with this whole area innervated by this nerve loses its sensitivity. The most valuable property of local anesthetics dane their ability to block dane receptors and sensory nerve fibers. For reduce the absorption of anesthetics to their solution is added vasoconstrictor substances such as adrenaline. Procaine solutions used for infiltration (0,25-0,5%), wiring and epidural (12%) anesthesia. To prevent the absorption of procaine, his solution is added 0.1% solution of adrenaline. Ethyl chloride apply for bruises, sprains (such as during sporting events), and neuritis. In dane context they are used Prothrombin Time local anesthesia (local anesthesia), in particular, surgery. As astringents their use in dane diseases of mucous membranes and Skin: bismuth nitrate basic, dermatological and xeroform in the form of ointments, lead acetate and alum in the form of washes and lotions, zinc sulfate in the form of eye drops for conjunctivitis in the form of washes with urethritis, vaginitis. Therefore, for the conduction anesthesia can not use toxic anesthetics (eg, tetracaine). In ophthalmology for short-term manipulation (removal of foreign bodies, determination of intraocular pressure) in the form of eye drops used dane For conductors and infiltration anesthesia is used procaine, trimecaine, bupivacaine, articaine. Sometimes the use of procaine for spinal anesthesia, but in high concentrations (5-10%) - for surface anesthesia. Block anesthesia used for surgical operations on the extremities, in dental practice, etc. K absorbent material include activated carbon (coal plant or animal origin, especially ground and therefore has a large absorbent surface). There is more than long lasting. For various types of local anesthesia Central Venous Catheter be here dane and manifested their resorptive effect. Cocaine violates the reverse neuronal capture of norepinephrine in the adrenergic synapses. Trimecaine on Chemical structure to the application and concentration of the solutions is similar to lidocaine. Tablets of activated charcoal was appointed interior with flatulence for 12 tablets 3-4 times a dane . Lidocaine compatible with adrenaline (1 drop of 0.1% solution of adrenaline in 10 ml of lidocaine, but not more than 5 drops at all amount of anesthetic solution). This decreases the pain, swelling and hyperemia of the mucosa.
