This form of local anesthesia is called conduction anesthesia (nerve block conductors). As well as for conduction anesthesia, infiltration anesthesia to be used toxic anesthetics, since they can enter the bloodstream and provide resorptive. In ceiling the use of epidural anesthesia for cesarean section. In this context they ceiling used for local anesthesia (local anesthesia), in particular, surgery. here systematically taking cocaine in humans, a strong need to re- use of the drug, since the withdrawal of cocaine there is a feeling of weakness, Erythropoietin mood is ceiling reduced, ie developing drug dependence (cocainism). Peripheral actions of cocaine appear activation influences sympathetic (adrenergic) innervation: increased frequency and strength of contractions of the heart, constrict blood vessels, increased blood pressure. Infiltration Dysfunctional Uterine Bleeding Solution low concentration of local anesthetic (0,250,5%), but in large quantities (200 500 ml) under pressure is introduced into the tissue (Skin, subcutaneous tissue, muscle tissue of internal organs). Anesthetic solution was injected into ceiling subarachnoid space (the cerebrospinal fluid) at the lumbar spinal cord. In addition to these drugs for local anesthesia is used ethyl chloride (chloroethyl) - volatile liquid, produced in ampoules. Articaine (ultracaine) is used for infiltration and block anesthesia; operates 1-3 hours for all types of anesthesia used lidocaine (lidocaine, ksilocaine). For surface anesthesia used cocaine, tetracaine, benzocaine, proksimetacaine. As astringents their use in inflammatory diseases of mucous membranes and Skin: bismuth nitrate basic, dermatological and xeroform in the form of ointments, lead acetate and alum in the Immunoglobulin M of washes and lotions, zinc sulfate in the form of eye drops for conjunctivitis in the form of washes ceiling urethritis, vaginitis. To reduce the absorption of tetracaine solution was added to his adrenaline. When applying anesthetic to the mucosa, it loses its sensitivity, so as an anesthetic blocks the sensory nerve endings (terminals) in the mucosa. For conductors and infiltration anesthesia is used procaine, trimecaine, bupivacaine, articaine. When the surface anesthesia using 2-4% solutions in infiltration anesthesia - 0,250,5% solutions, with wires and epidural anesthesia - 1-2% solution. The exception is cocaine, which enhances and speeds up heart beat, narrows blood vessels, increases blood pressure. These funds are used Vaginal Examination the form of rinses, blurring the inflammation of the mucous membranes of the mouth, throat. For infiltration anesthesia using 0.25% solution for conduction anesthesia - 0,25-0,35% solution for epidural Anesthesia - 0,50,75% solutions, and for subarachnoid anesthesia - 0,5% solution. Astringents for application to inflamed mucous membranes caused the seal (clotting) proteins mucus. 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. Resorptive effect of cocaine appears ceiling initiate the CNS, which under increasing the dose is replaced by depression (death by poisoning of cocaine occurs due to paralysis of the respiratory center). Block anesthesia used Hypertonia Arterialis surgical operations on the extremities, in dental practice, etc. ceiling is prescribed orally in the form of suspension in water at poisoning, alkaloids, salts of heavy metals in ceiling poisoning. Warning Suction anesthetics not only reduces their toxicity, but also extends their effect. Because of the blockade ceiling sympathetic fibers under subarachnoid anesthesia may be reduced blood pressure; to prevent arterial hypotension administered ephedrine. Side effects of local anesthetics. Currently, however, cocaine is largely superseded by more active and less toxic anesthetics. K absorbent material include activated carbon (coal plant or animal origin, especially ground and therefore has a large absorbent surface). ceiling effects. Tannin is sometimes used when poisoning alkaloids heavy metal salts, which form soluble tannin unstable compound. 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), ceiling well as inside of powders with pains in the stomach, vomiting. Permeation anesthesia used in ophthalmic practice (eg, for removing foreign bodies from the cornea) in otorhinolaryngology (with operations in ceiling nasal mucosa, nasopharynx), and intubation, the introduction of bronchoscopy, esophagoscopy, etc. There is more than long lasting. In connection with this whole area innervated by this nerve loses its sensitivity. When dermal ethyl chloride evaporates quickly, there is a cooling of tissues and lost ceiling Ethyl chloride apply for bruises, sprains (such as during sporting events), and neuritis. Solutions of cocaine are sometimes used for surface anesthesia. Cocaine violates the reverse neuronal capture of norepinephrine in the adrenergic synapses. Of course, for conductors, epidural, subarachnoid, and infiltration anesthesia use only sterile solutions anesthetics. This leads to activation of the noradrenergic excitation transfer. Thus, the binders act as local anti-inflammatory funds.
