Succinylcholine chloride

Succinylcholine Chloride is the chloride salt form of succinylcholine, a quaternary ammonium compound and depolarizing agent with short-term muscle relaxant properties.Succinylcholine chloride binds to nicotinic receptors at the neuromuscular junction and opening the ligand-gated channels in the same way as acetylcholine, resulting in depolarization and inhibition of neuromuscular transmission. Neuromuscular blockers in surgery and intensive care, part 2.

Blood testing for cholinesterase function can be performed.Deliberate induction of conscious apnea using this drug led to its use as a form of There are two phases to the blocking effect of suxamethonium. Bethesda, MD: American Society of Health-System Pharmacists; 2013:1057-60.The easiest way to lookup drug information, identify pills, check interactions and set up your own personal medication records. Bethesda, MD: American Society of Health-System Pharmacists; 2018.c. The former is a major point of consideration in the context of trauma care, where endotracheal intubation may need to be completed very quickly. The multi-dose vials are stable for up to 14 days at room temperature without significant loss of potency.The side effect of high blood potassium may occur because the acetylcholine Severely high blood levels of potassium will cause changes in Susceptibility to malignant hyperthermia is often inherited as an The normal short duration of action of suxamethonium is due to the rapid metabolism of the drug by non-specific plasma cholinesterases. We comply with the HONcode standard for trustworthy health information - Rocuronium versus succinylcholine for rapid sequence induction intubation. Genetically, ninety six percent of the population have a normal (Eu:Eu) genotype and block duration; however, some people have atypical genes (Ea, Es, Ef) which can be found in varying combinations with the Eu gene, or other atypical genes (see If unrecognized by a clinician it could lead to awareness if anesthesia is discontinued whilst still paralyzed or hypoxemia (and potentially fatal consequences) if artificial ventilation is not maintained.

Synthetic, ultrashort-acting depolarizing neuromuscular blocking agent with high affinity for acetylcholine (ACh) receptor sites. McManus MC. The latter means that, should attempts at endotracheal intubation fail and the person cannot be ventilated, there is a When studying the drug, animals were given It is available in German-speaking countries under the trade name Lysthenon among others.[Cl-]. McEvoy GK, ed. 423. Murray MJ, DeBlock H, Erstad B et al. Clinical practice guidelines for sustained neuromuscular blockade in the adult critically ill patient. Its medical uses are limited to short-term muscle relaxation in anesthesia and intensive care, usually for facilitation of endotracheal intubation. Succinylcholine chloride dehydrate was used to study the mechanism of gating of Cys loop receptors in Xenopus laevis. Clinical Practice Guidelines for Sustained Neuromuscular Blockade in the Adult Critically Ill Patient. It is popular in emergency medicine due to its rapid onset and brief duration of action. Normal treatment is to maintain sedation and ventilate the patient on an intensive care unit until muscle function has returned. Risk of acute rhabdomyolysis with hyperkalemia followed by ventricular arrhythmias, cardiac arrest, and death in apparently healthy children and adolescents who subsequently were found to have undiagnosed skeletal muscle myopathy (e.g., Duchenne’s muscular dystrophy).Use in children and adolescents should be reserved for those undergoing emergency intubation, those in whom an airway should be secured immediately (e.g., patients with laryngospasm, difficult airway, or full stomach), or those in whom a suitable vein is not accessible and IM administration is needed.Should be administered only by individuals experienced in the use of neuromuscular blocking agents.Production of skeletal muscle relaxation during procedures of short duration (e.g., endotracheal intubation) after general anesthesia has been induced;Because of serious adverse effects, restrict use in pediatric population.Facilities and personnel necessary for intubation, administration of oxygen, and respiratory support should be immediately available.Take special precautions (e.g., segregate storage, limit access, affix warning labels to storage containers and final administration containers) to ensure that the drug is not administered without adequate respiratory support.To avoid patient distress, generally administer only after unconsciousness has been induced; however, may administer before sedative administered in emergency situations.To evaluate patient’s ability to metabolize succinylcholine and to determine individual patient sensitivity and recovery time, a test dose may be administered to spontaneously breathing patient after anesthesia has been induced.Assess neuromuscular blockade and recovery in patients undergoing anesthesia;For specific procedures and techniques of administration, consult specialized references.For solution and drug compatibility information, see Compatibility under Stability.For prolonged procedures, may administer by continuous IV infusion (preferably) or intermittent IV injection.Multiple fractional doses generally should not be used; repeated fractional doses and, to a lesser extent, continuous infusion, may lead to tachyphylaxis.For continuous IV infusion, dilute succinylcholine chloride to the desired concentration (usually 1–2 mg/mL) in a compatible IV solution (e.g., 5% dextrose injection, 0.9% sodium chloride injection).May administer by IM injection if IV access not available.Available as succinylcholine chloride; dosage expressed in terms of the salt.Carefully adjust dosage according to individual requirements and response.Continuous IV infusions considered unsafe in neonates and children.Infants and older children: If IM administration necessary, a dose of up to 3–4 mg/kg (maximum 150 mg) may be given.To evaluate sensitivity to succinylcholine in patients with reduced plasma cholinesterase activity, administer test dose of 5–10 mg or cautiously administer a 1-mg/mL solution by slow IV infusion.For short procedures, usual dose is 0.6 mg/kg (range 0.3–1.1 mg/kg).For prolonged procedures, usual dosage is 2.5–4.3 mg/minute by continuous IV infusion; adjust rate (range: 0.5–10 mg/minute) depending on patient’s response and requirements.For rapid sequence intubation, usual dose is 1.5 mg/kg; generally produces onset of effect within 45 seconds and duration of paralysis of about 10 minutes.If IM administration necessary, a dose of up to 3–4 mg/kg (maximum 150 mg) may be given.Careful dosage selection recommended due to possible age-related decrease in hepatic, renal, and/or cardiac function and concomitant disease and drug therapy; initiate therapy at low end of dosage range.Administer small test dose (5–10 mg) or cautiously administer 1-mg/mL solution by slow IV infusion.Personal or familial history of malignant hyperthermia.Upper motor neuron injury, multiple trauma, extensive or severe burns, extensive denervation of skeletal muscle because of CNS disease or injury.Known hypersensitivity to succinylcholine or any ingredient in the formulation.Potential for acute rhabdomyolysis with hyperkalemia.Possible severe hyperkalemia resulting in serious cardiac arrhythmias or cardiac arrest in patients with upper motor neuron injury, multiple trauma, extensive or severe burns, or extensive denervation of skeletal muscle because of CNS disease or injury; use is contraindicated in these patients.Use with extreme caution in patients with preexisting hyperkalemia or those at increased risk of hyperkalemia (e.g., those with paraplegia, chronic abdominal infection, tetanus, subarachnoid hemorrhage, degenerative or dystrophic neuromuscular disease, or conditions that may cause degeneration of central and peripheral nervous systems).Use with extreme caution in patients receiving quinidine or cardiac glycosides or those with suspected cardiac glycoside toxicity (due to potential for hyperkalemia).Serious hypersensitivity reactions, including anaphylaxis, reported rarely.Take appropriate precautions; emergency treatment for anaphylaxis should be immediately available.Because of the potential for severely compromised respiratory function and other complications, take special precautions during administration.Possible fatal malignant hyperthermia; manifested by a rapid, profound elevation in body temperature and sometimes extreme muscular rigidity.If malignant hyperthermia occurs, discontinue all anesthetic agents and initiate IV dantrolene therapy in conjunction with supportive measures (e.g., administering oxygen, treating metabolic acidosis, instituting cooling procedures); maintain urinary output and monitor serum electrolytes.Possible profound bradycardia resulting from vagal stimulation and accompanied by hypotension and cardiac arrhythmias (e.g., nodal rhythms, extrasystoles, bigeminy, AV block, cardiac arrest).Occurs most commonly with repeated administration and in childrenPrior administration of atropine may inhibit vagal stimulation and reduce occurrence of bradycardia.Use with extreme caution in patients with electrolyte disturbances, those receiving quinidine or cardiac glycosides, or those with suspected cardiac glycoside toxicity.Possible tachyphylaxis with repeated administration;Possible prolonged neuromuscular blockade due to change of the characteristic depolarizing neuromuscular block (phase I block) to a phase II block.To reverse phase II block, may administer a cholinesterase inhibitor (e.g., neostigmine, pyridostigmine, edrophonium), in conjunction with an antimuscarinic (e.g., atropine, glycopyrrolate) to prevent disturbances in cardiac rhythm.To ensure complete hydrolysis of succinylcholine by plasma pseudocholinesterase prior to administration of cholinesterase inhibitor, do not attempt reversal unless spontaneous recovery of muscle twitch has been observed for ≥20 minutes and has plateaued, with further recovery from neuromuscular blockade occurring slowly.Possible slight, transient increase in intracranial pressure.Possible increased intragastric pressure secondary to fasciculation of abdominal muscles; potential for regurgitation and possible aspiration of stomach contents.Possible prolonged respiratory depression and muscle relaxation in patients with reduced plasma cholinesterase activity.Plasma cholinesterase activity may be reduced in patients heterozygous or homozygous for the atypical pseudocholinesterase gene, pregnant women, and patients with severe hepatic or renal disease, malnutrition, infections, severe anemia, severe dehydration, burns, cancer, collagen diseases, myxedema, decompensated heart disease, peptic ulcer disease, or abnormal body temperature.Some clinicians recommend determining plasma pseudocholinesterase activity prior to administration.Administer with extreme caution and in reduced doses, if at all, in patients with abnormally low pseudocholinesterase concentrations.Treat apnea or prolonged muscle paralysis with controlled respiration.Possible prolonged neuromuscular blockade in patients with electrolyte disturbances (e.g., hypocalcemia, hypokalemia).Possible histamine release; manifestations associated with histamine release (e.g., flushing, erythema, pruritus, urticaria, wheal formation, wheezing, bronchospasm, hypotension) uncommon at usual dosages.Use with caution in patients with fractures, dislocations, or muscular spasms; initial muscle fasciculation may cause additional trauma.Use not recommended in patients with angle-closure glaucoma or penetrating eye injuries.Not known whether succinylcholine is distributed into milk.Possible acute rhabdomyolysis with hyperkalemia followed by ventricular arrhythmias, cardiac arrest, and death; usually occurs in males ≤8 years of age.Possible profound bradycardia or, rarely, asystole when administered by rapid IV injection.Possible risk of malignant hyperthermia; institute appropriate therapy if malignant hyperthermia occurs.Use with caution due to greater frequency of decreased hepatic, renal, and/or cardiac function and of concomitant disease and drug therapy observed in the elderly.Possible decreased plasma cholinesterase activity in patients with severe hepatic impairment;Possible decreased plasma cholinesterase activity in patients with severe renal impairment.Antiarrhythmic agents (lidocaine, procainamide, quinidine)Anti-infective agents (aminoglycosides, bacitracin, clindamycin, lincomycin, polymyxins, tetracyclines)Cholinesterase inhibitors (demecarium, isofluorophate, organophosphate insecticides)Possible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadePossible decreased plasma cholinesterase activity and increased neuromuscular blockadeFollowing IV administration, onset is rapid; complete muscle relaxation occurs within 0.5–1 minute following 10- to 30-mg dose.Following IM administration, onset occurs in about 2–3 minutes.Following IV administration, duration of action is short (about 2–3 minutes following 10- to 30-mg dose; effects gradually dissipate within 10 minutes).Following IM administration, duration of action ranges from 10–30 minutes.Duration of action is prolonged in patients with low plasma pseudocholinesterase concentrations.Rapidly hydrolyzed by plasma pseudocholinesterase to succinylmonocholine and then more slowly to succinic acid and choline.Excreted in urine as active and inactive metabolites and small amounts of unchanged drug.Severe hepatic impairment may decrease plasma pseudocholinesterase activity, resulting in increased duration of action due to reduced metabolism.In patients with renal impairment, possible decreased plasma pseudocholinesterase activity and possible accumulation of succinylmonocholine.For information on systemic interactions resulting from concomitant use, see Interactions.May be incompatible with alkaline solutions with pH >8.5 (e.g., barbiturate solutions).Dextrose–Ringer’s injection, lactated, combinationsHeparin sodium with hydrocortisone sodium succinateHetastarch in lactated electrolyte injection (Hextend)Produces skeletal muscle relaxation by causing a decreased response to acetylcholine (ACh) at the myoneural (neuromuscular) junction of skeletal muscle.Exhibits high affinity for ACh receptor sites and produces depolarization of motor end-plate at myoneural junction, resulting in transient twitching or fasciculation of skeletal muscles, followed by muscle paralysis (phase I block).Prolonged or repeated administration results in gradual and variable transition to phase II block, which resembles nondepolarizing block.Phase I block is potentiated by cholinesterase inhibitors and can be reversed by nondepolarizing neuromuscular blocking agents; fully established phase II block can be reversed by cholinesterase inhibitors and potentiated by nondepolarizing agents.Stimulates cardiac vagus and subsequently sympathetic ganglia.Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.Importance of informing clinician of existing or contemplated concomitant therapy, including prescription and OTC drugs, as well as any concomitant illnesses (e.g., cardiovascular disease, neuromuscular disease).Importance of informing patients of other important precautionary information.110.
