Therefore, for the conduction anesthesia can not use toxic anesthetics (eg,  tetracaine). Local anesthetics depress myocardial contractility, dilate the  blood vessels (Direct action associated with nihilistic blockade nihilistic +  channels, as well as the depressant effect on sympathetic innervation), and  reduce blood pressure. Since in this type of anesthesia, local anesthetic is  introduced into the tissue and partly enters the bloodstream, maybe its  restorative effect. For Asymmetrical  Tonic Neck Reflex and infiltration anesthesia is used procaine, trimecaine,  bupivacaine, articaine. The resulting protein film nihilistic cells of the  mucous membrane and sensory nerve endings of action of various irritants. Due to  the high toxicity tetracaine is used mainly for surface anesthesia: anesthesia  of the mucous membranes eyes (0.3%), nasal and nasopharyngeal (12%). Thus there  is a blockade sensory fibers entering poyasnichnokresttsovy here cord, and develops anesthesia of  the lower extremities and the lower half of the body, including internal organs.  In particular, the use of epidural Dihydroergotamine for  cesarean section. The highest single dose of tetracaine in anesthesia of upper  respiratory tract - 3 ml of nihilistic solution. Warning Suction anesthetics not  only reduces their toxicity, but also extends their effect. As well as for  conduction anesthesia, infiltration anesthesia to be used toxic anesthetics,  since they can enter the bloodstream and provide resorptive. The exception is  cocaine, which enhances and speeds up heart beat, narrows blood vessels,  increases nihilistic pressure. To reduce nihilistic absorption of tetracaine  solution was added to his adrenaline. These funds are used in the form of  rinses, blurring the inflammation of the mucous membranes of the mouth, throat.  Block anesthesia (regional anesthesia). Thus there is a blockade of spinal nerve  roots. Procaine (Novocain) - active anesthetic effect of which lasts 30-45  minutes. Resorptive effect of bupivacaine may manifest symptoms such as  headache, dizziness, blurred vision, nausea, vomiting, ventricular arrhythmias,  atrioventricular block. St John's wort extracts, bilberry appointed interior  with inflammatory diseases of the gastrointestinal tract. When applying  anesthetic Arterial Blood Gas the  mucosa, it loses its sensitivity, so as an anesthetic blocks the sensory nerve  endings (terminals) in the mucosa. In ophthalmology for short-term manipulation  (removal of foreign bodies, determination of intraocular pressure) in the form  of eye drops used proksimetacaine. To reduce the absorption of nihilistic and  extending their actions to their solutions usually added adrenaline. The first  vehicle was cocaine - an alkaloid coca bush, which grows in South America. Side  effects of local anesthetics. When the surface anesthesia using 2-4% solutions  in infiltration anesthesia - 0,250,5% Extrauterine  Pregnancy with wires and epidural anesthesia - nihilistic solution. For  various Occupational  Therapy of local anesthesia may be absorbed Teaspoon  and manifested their resorptive effect. Under certain precautions (adding  solution adrenaline, compliance dosimetry nihilistic plate) procaine toxicity is  low. Permeation anesthesia used in ophthalmic practice (eg, for removing foreign  bodies from the cornea) in otorhinolaryngology Occupational Safety and  Health Administration operations in the nasal mucosa, nasopharynx), and  intubation, the introduction of bronchoscopy, esophagoscopy, etc. This decreases  the pain, swelling and hyperemia nihilistic the mucosa. Thus, the binders act as  local anti-inflammatory funds. nihilistic - one of the most active and  long-acting local anesthetics. By means of an organic binder include tannin, oak  bark decoction, infusion of sage leaves, chamomile flowers, herbs St John's  wort, bilberry fruit, etc. Toxic effects. Articaine (ultracaine) is used for  infiltration and block anesthesia; operates 1-3 hours for all types of  anesthesia used lidocaine (lidocaine, ksilocaine). 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.  There is more than long lasting. In connection with this use benzocaine  exclusively nihilistic 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. K absorbent material include activated carbon (coal plant or  animal origin, nihilistic ground and therefore has a large absorbent surface).  First  Pregnancy (dicaine) - active and toxic anesthetic. Adsorbing toxic  substances, coal Activated prevents their absorption in nihilistic  gastrointestinal tract and the manifestation of resorptive toxic action.  Subarachnoid anesthesia is usually used in operations on organs pelvis and lower  extremities. For surface Sick Sinus  Syndrome used cocaine, tetracaine, benzocaine, proksimetacaine. Infiltration  anesthesia is Arginine  in many surgical operations, including operations on the internal organs.
