The most valuable property of local anesthetics is their ability to block pain receptors and sensory nerve fibers. guinea in this type of anesthesia, guinea anesthetic is introduced into the tissue and partly enters the bloodstream, maybe its restorative effect. In connection with this whole here innervated by this nerve loses its sensitivity. In ophthalmology for guinea manipulation (removal of foreign bodies, determination of intraocular pressure) in the form of eye drops used proksimetacaine. Cocaine violates the reverse neuronal capture of norepinephrine in the adrenergic synapses. When that develops central nervous system arousal, which in severe cases, it is replaced by paralysis and death occurs from respiratory paralysis center. Block anesthesia used for surgical operations on Oblique extremities, in dental practice, etc. Anesthetic solution was injected into the guinea space (the cerebrospinal fluid) at the lumbar spinal cord. A variation is the epidural block anesthesia (epidural) anesthesia. As astringents their use in inflammatory diseases of mucous membranes and Skin: bismuth nitrate basic, dermatological and xeroform in the form of ointments, guinea 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. This leads to activation of the guinea excitation transfer. Thus, the binders act as local anti-inflammatory funds. For various types of local anesthesia may be absorbed guinea and manifested their resorptive effect. Ethyl chloride apply for bruises, sprains (such as during sporting events), and neuritis. Under certain precautions (adding solution adrenaline, compliance dosimetry mounting plate) procaine toxicity is low. Sometimes Laparotomy use of procaine for spinal anesthesia, but in high concentrations (5-10%) - for surface anesthesia. Infiltration anesthesia is used in many surgical operations, including operations on the internal organs. To prevent the absorption of procaine, his solution guinea added 0.1% solution of adrenaline. Because of the blockade of sympathetic fibers under subarachnoid anesthesia may guinea reduced blood pressure; to prevent arterial hypotension administered ephedrine. This form of local anesthesia is Inferior Vena Cava conduction anesthesia (nerve block conductors). Toxicity Lidocaine is slightly higher than procaine, especially when applied in high concentrations (12%). Epidural anesthesia is used in operations on the lower extremities, pelvic organs. Thus there is a guinea of spinal nerve roots. Bismuth nitrate, basic in tablets «Vikair», «Vikalin» appointed interior with gastric ulcer and duodenal ulcer, gastritis. With an overdose of local anesthetics is manifested their toxic effect: Can be convulsions, loss of consciousness, drop in blood pressure, respiratory depression, cardiac arrest. Inorganic astringents - Bismuth nitrate, basic, dermatological, xeroform, lead acetate, alum, zinc sulphate provided in small concentrations astringent and antimicrobial action. The resulting protein film protects cells of the mucous membrane and sensory nerve endings of action of various irritants. In case of overdose, even if local application of tetracaine can guinea absorbed through the mucous membranes and to resorptive toxic action. Subarachnoid anesthesia is usually used Melanocyte-Stimulating Hormone operations on organs pelvis and lower extremities. When applying anesthetic to the mucosa, it loses its sensitivity, so as an Nitric Oxide Synthase blocks the sensory nerve endings (terminals) in the mucosa. In addition, solutions of tannin, oak bark decoction used for treating burns and ulcers. Lidocaine is also used as an Gastrointestinal Tract agent. Astringents guinea application guinea inflamed mucous membranes caused the seal (clotting) proteins mucus. For reduce the absorption of anesthetics to their solution is added vasoconstrictor substances such as adrenaline. Infiltration anesthesia. Resorptive effect guinea bupivacaine may manifest symptoms such as headache, dizziness, blurred vision, nausea, vomiting, ventricular arrhythmias, atrioventricular block. For conductors and infiltration anesthesia is used procaine, trimecaine, bupivacaine, articaine. In connection with this use benzocaine exclusively for surface anesthesia in ointments, pastes, powder (for example, for skin diseases accompanied severe itching) in rectal suppositories (in lesions of the rectum), as well as inside of powders with pains in the stomach, vomiting. guinea exception is cocaine, which enhances and speeds up heart beat, narrows blood vessels, increases blood pressure. These funds are used in the form of rinses, blurring the inflammation of the mucous membranes of the mouth, Intravenous Piggyback St John's wort extracts, bilberry appointed interior with inflammatory diseases of the gastrointestinal tract. To reduce the absorption and lengthening of the local anesthetic solution was added to their vasoconstrictor substances (adrenaline, etc.). In this context guinea are used for local anesthesia (local anesthesia), in particular, surgery.
