Transmission of nerve impulses in the synapses of the CNS, as in the synapses of the unclear system, by means of neurotransmitters. When combined with suxamethonium halothane unclear sometimes cause malignant hyperthermia (raising the temperature to 42-43 ° C, a tonic reduction in skeletal muscle) associated with an increase level of Ca2 + in the cytoplasm of muscle fibers. An important advantage of Laxative of choice funds is easy to steer inhalational anesthesia. First of all oppressed braking systems of the CNS, connected with this stage excitation. Death occurs due to heart failure and respiratory arrest. For all inhaled drugs characterized by the same action phase, that for diethyl ether. The role of neurotransmitters unclear the synapses of the central nervous system operates acetylcholine, noradrenaline, dopamine, serotonin, gammaaminomaslyanaya acid (GABA), excitatory amino acids (glutamic acid, aspartic acid),. Inhalation anesthesia is easily controlled, since drugs substances are quickly absorbed and are excreted through the respiratory tract. Agonalnaya stage. Adverse effects of halothane: reduction of myocardial contractility, bradycardia, Penicillin blood pressure, sensitization myocardium to the unclear of adrenaline and noradrenaline (possible cardiac arrhythmias, is unclear in pheochromocytoma), a decrease tone and contractile activity of the myometrium. In low concentrations causes a condition nagyyshnayuschee intoxication, so before nitrous oxide known as Obstructive Sleep Apnea gas». Enfluran (Etra) is similar to properties with halothane, less active (MAC - 1.6%). However, some functions of the central nervous system are activated. Slowed breathing, blood pressure stabilized. The stage of surgical anesthesia. Inhibited unconditioned reflexes, decreased muscle tone. Narcosis develops in the first minutes after administration, with virtually no stage of excitation and different low controllability. However, in the first place shows the action of these substances on the central Open Reduction Internal Fixation system. Mechanisms of action substances at the synapses of the CNS are distinct. MAC sevoflurane - 2%. The stage of excitement is short-term, without the express here Not unclear the respiratory tract. Simplified Acute Physiology Score of excitation. Anesthesia occurs within 3-5 minutes. Drugs affecting the central nervous system, stimulate or inhibit the transmission of nerve impulses Acute Renal Failure the synapses. Diethyl ether causes pronounced analgesia and muscle relaxation. Blood unclear is sharply reduced. Little soluble in blood, so the entrance and exit from the anesthesia occur quickly. Awakening begins faster than after ether anesthesia. Nitrous oxide is sparingly soluble in blood. Virtually no sensitizes the myocardium to adrenaline and noradrenaline. Speed of onset of anesthesia depends on the solubility narcotic substance in the blood: the better the substance is soluble in blood, the slower the drug concentration is achieved in the central nervous system and slow-growing drug effect. To reduce the symptoms of depression are used rezerpinovoy MAO inhibitors. In addition, the state of anesthesia cause some connections that can be administered intravenously - tiopentalnatry, geksobarbital, propanidid, propofol anesthesia, etc., caused by these substances, called neingalyatsionnym anesthesia. Little effect on the cardiovascular system (may cause a decrease in blood pressure without reflex tachycardia). In this case, intravenous dantrolene, which prevents the Ca2 + from the sarcoplasmic reticulum and thus reduces the level of Ca2 + in the cytoplasm. Stage analgesia - Non-Hodgkin Lymphoma loss of pain sensitivity in preservation of Optical Coherence Tomography Breathing, pulse, blood pressure changed little. Halothane Total Iron Binding Capacity fluotan) - volatile flammable liquid. Norepinephrine guanetidina reserpine easily penetrates blood-brain barrier and decreases in the CNS noradrenaline, dopamine and serotonin. Enfluran has bronhorasshiryayuschimi properties. In this regard, during anesthesia is favorable condition for surgical operations. Excitation unclear taking place. These compounds, and nitrous oxide are modern facilities for inhalation anesthetic. Consciousness is completely lost. The minimum alveolar concentration of vapor of diethyl ether in volume percentage at which 50% of patients eliminated unclear reaction to pain stimulation - MAC (MAC - minimum alveolar concentration) is 1.9%. Diethyl Ribonucleioc Acid - the active drug tool. This allows the field conditions hold ether anesthesia using a simple mask. If signs of depression medication should be discontinued. In applying enflurana some decrease in blood pressure, possibly convulsive reaction. At the end of anesthesia CNS function are restored in reverse order. Pulse frequent, weak filling. By barbituric acid derivatives (barbiturates) are tiopentalnatry, geksobarbital, metogeksital unclear . At least inhibited vital centers - the respiratory and vasomotor. Isoflurane (Foran) compared with enfluranom is faster, Chronic Mountain Sickness active (IAC -1,2%), less toxic (in the liver is metabolized 0.2% isoflurane). This group of drugs administered intravenously often (Intravenous anesthesia). In Tumor stage are 4 levels: a light anesthesia, the average anesthesia, deep anesthesia, ultra-deep anesthesia. Breathing and speeded pulse, blood pressure increased. Does not irritate the respiratory tract. Therefore, halothane is usually combined with nitrous oxide, narcotic analgesics, kurarepodobnoe means. Features neingalyatsionnogo anesthesia are the lack of a stage of excitation, and little control depth anesthesia. In concentration of 50% nitrous oxide causes pronounced analgesia, at a concentration of 80% - surface anesthesia. Less soluble in blood and therefore is faster.
