Z40 Prophylactic surgical intervention

Code CAS 541-19-5


Miorelaxant of peripheral action (depolarizing). The chemical structure is a doubled molecule of acetylcholine (diacetylcholine).

White or white with a slightly yellowish tint fine crystalline powder odorless. Easily soluble in water, practically insoluble in 95% alcohol and chloroform. The melting point is 250-255 ° C. The pH of a 1% solution is 4.5-6.2.


Pharmacological action - miorelaksiruyuschee.

Depolarizing short-acting muscle relaxant. Violates the conduct of neuromuscular stimulation and causes relaxation of skeletal muscles. Competing with acetylcholine for n-holinoretseptory, causes a persistent depolarization of the terminal plate due to high affinity for cholinergic receptors and resistance to acetylcholinesterase. At first, the development of depolarization is manifested by fasciculations (generalized disorganized contraction of myofibrils) due to short-term relief of neuromuscular transmission, then the depolarized membranes cease to respond to additional impulses and the myoparalytic effect occurs (spastic paralysis occurs). After iv introduction miorelaxation develops in the following sequence: the muscles of the fingers, eyes, legs, neck, back; Then intercostal muscles and diaphragm. Causes an increase in cerebral blood flow and intracranial pressure in conditions of weak general anesthesia. After the / m introduction, the effect develops in 2-4 minutes, after iv introduction - after 54-60 seconds, the maximum effect develops in 2-3 minutes and remains in full for 3 minutes. Duration of action 5-10 minutes.

The severity of the effect depends on the dose: 0.1 mg / kg - relaxation of the skeletal muscles without a significant effect on the respiratory system, 0.2-1 mg / kg - complete relaxation of the musculature of the abdominal wall and respiratory muscles (significant restriction or complete stop of spontaneous breathing). Has a quick and short-term effect. Does not cumulate. For prolonged muscle relaxation, repeated administration is necessary. The rapid onset of the effect and the subsequent rapid recovery of neuromuscular conduction allow the creation of a controlled and controlled miorelaxation.

After intravenous administration is distributed in plasma and extracellular fluid. More than 90% is hydrolyzed by pseudocholinesterase of blood to succinic acid and choline. T1 / 2 - 90 s at a normal level of pseudocholinesterase. It is excreted by the kidneys. Does not penetrate intact GEB.


Interventions requiring miorelaxation (usually short-term): disabling of spontaneous breathing (intratracheal intubation, bronchoscopy); Complete miorelaxation (endoscopy, electroencephalography, correction of dislocations, reposition of bone fragments in fractures, gynecological, thoracic, abdominal operations); Prevention of seizures in electropulse therapy, strychnine poisoning, tetanus (symptomatic therapy).


Hypersensitivity, malignant hyperthermia (including in history, family), congenital and dystrophic myotonia, Duchenne muscular dystrophy, angle-closure glaucoma, acute liver failure, pulmonary edema, penetrating eye trauma, bronchial asthma, hyperkalemia, age under 1 year.

Restrictions on the use

Emergency surgery in patients with a "full stomach", myasthenia gravis, terminal stage of hepatic insufficiency, anemia, cachexia, prolonged fasting, chronic infections, widespread burns, trauma, postpartum period, tetanus, tuberculosis, malignant neoplasms, chronic renal failure, myxedema, collagen diseases , Conditions after a plasma transfusion, plasmapheresis, artificial circulation, acute or chronic intoxication with insecticides - cholinesterase inhibitors (if ingested) or with anticholinesterase drugs (neostigmine, physostigmine, distigmine, phospholin), concurrent administration of drugs that compete with suxamethonium for cholinesterase (eg procaine in /at). In children older than 1 year is not recommended for unscheduled operations.

pregnancy and lactation

With caution in pregnancy (passes through the placental barrier).

Side effects

From the cardiovascular system: lowering blood pressure, arrhythmia, bradycardia (more often in children, with repeated administration - in children and adults), conduction disorders, cardiogenic shock.

Allergic reactions: anaphylactic shock, bronchospasm.

Other: hyperkalaemia, increased intraocular pressure, changes in secretion of salivary glands, fever, myalgia (10-12 hours after administration), prolonged paralysis of the respiratory muscles (associated with a genetically determined violation of serum cholinesterase formation); Rarely - rhabdomyolysis with the development of myoglobinemia and myoglobinuria.


Enhances the effects of cardiac glycosides. Reduces the effectiveness of antimiasthenic drugs. Incompatible with donor blood (hydrolysis of the drug), blood preservatives, whey preservatives, with blood products, with solutions of barbiturates (a precipitate is formed) and alkaline solutions. Compatible with 0.9% solution of sodium chloride, Ringer's solution, 5% solution of fructose and 6% solution of dextran.

Strengthen and prolong the muscle relaxant effect: anticholinesterase drugs and drugs that have the potential to reduce the activity of cholinesterase (aprotinin, diphenhydramine, promethazine, estrogens, oxytocin, high-dose glucocorticosteroids, oral contraceptives), procaine, procainamide, lidocaine, verapamil, beta-blockers, Aminoglycosides, amphotericin B, clindamycin, cyclopropane, propanidide, organophosphate insecticides, magnesium and lithium salts, quinidine, quinine, chloroquine, pancuronium bromide. Compatible with other muscle relaxants, narcotic analgesics. Halogen containing drugs for general anesthesia are enhanced, and sodium thiopental and atropine reduce the undesirable effect on the cardiovascular system.


Symptoms: prolonged respiratory depression, stopping breathing.

Treatment: IVL; With a decrease in the content of cholinesterase in the blood serum - transfusion of fresh blood (high activity of cholinesterase plasma), correction of electrolyte disturbances.

Routes of administration

In / in.


With caution apply for diseases of the cardiovascular system, respiratory diseases, neuromuscular diseases, increased intraocular pressure.

Possible use in patients with myasthenia gravis. It should be remembered that patients with myasthenia gravis (they have a reduced number of functioning n-holinoretseptorov) are relatively resistant to the action of drugs, but with the development of a double block, the recovery of neuromuscular conduction slows down.

Neostigmine methyl sulfate (Proserin) or other anticholinesterase drugs are not antagonists of suxamethonium iodide, on the contrary, by suppressing cholinesterase activity, they prolong and intensify the action. Preliminary (per 1 min) administration of 3-4 mg of d-tubocurarine or 10-15 mg of diplatcin dichloride almost completely prevents fasciculation and subsequent muscle pain.

For prolonged operations, nondepolarizing muscle relaxants are usually used, which are administered after a pre-intubation of the trachea against a background of suxamethonium iodide. Applied only in the conditions of a specialized department, with the availability of equipment for ventilation and personnel who own this technique.

In large doses or with repeated administration, it can cause a "double block": if after the last administration the muscle relaxation is more than 25-30 minutes and breathing is not completely restored, IV neostigmine methylsulfate (Proserin) or galantamine - after preliminary administration of atropine (0, 5-0.7 ml of a 0.1% solution).
