Generic Name and Formulations:
Succinylcholine chloride 20mg/mL, 100mg/mL; soln for IM or IV inj.
Indications for QUELICIN:
Adjunct to general anesthesia to facilitate tracheal intubation, and to provide skeletal muscle relaxation during surgery or mechanical ventilation.
Individualize. Patients homozygous for atypical plasma cholinesterase gene: give test dose of 5–10mg (1mg/mL solution) by slow IV infusion. Short surgical (tracheal intubation): usual dose: 0.6mg/kg IV; range: 0.3–1.1mg/kg IV. Long surgical: (1–2mg/mL solution) by continuous infusion given at a rate of 2.5–4.3mg/min; alternatively by intermittent IV inj: initially 0.3–1.1mg/kg, followed by 0.04–0.07mg/kg. If suitable vein is inaccessible, may give by IM inj: up to 3–4mg/kg, max 150mg total dose.
See literature. Emergency tracheal intubation: infants and small children: 2mg/kg IV; older pediatric patients and adolescents: 1mg/kg IV. If suitable vein is inaccessible, may give by IM inj: up to 3–4mg/kg, max 150mg total dose.
History of malignant hyperthermia or skeletal muscle myopathies. Acute phase of injury following major burns, multiple trauma, extensive denervation of skeletal muscle, or upper motor neuron injury.
To be administered only by those skilled in management of artificial respiration. Have intubation, adequate ventilation, oxygen therapy available. Should not be administered prior to induction of unconsciousness (unless emergency). Pretreatment with anticholinergic agents (eg, atropine) may reduce occurence of bradyarrythmias. Caution in patients with reduced plasma cholinesterase activity in presence of gene abnormalities (eg, heterozygous or homozygous for atypical plasma cholinesterase gene), pregnancy, severe hepatic or renal disease, malignant tumors, infections, burns, anemia, heart disease, peptic ulcer, myxedema, or drugs affecting cholinesterase activity (see Interactions). Electrolyte abnormalities, digitalis toxicity, acute phase of injury (see Contraindications), chronic abdominal infection, subarachnoid hemorrhage, or conditions causing degeneration of central and peripheral nervous systems: increased risk of hyperkalemia. Hypokalemia or hypocalcemia (neuromuscular blockade may be prolonged). Monitor for possible transition into Phase II block (see literature). Glaucoma or eye injury. Bone fractures or muscle spasm. Children with skeletal muscle myopathy. Elderly. Pregnancy (Cat. C). Labor & delivery. Nursing mothers.
Potentiated by promazine, oxytocin, aprotinin, certain non-penicillin antibiotics, quinidine, β-adrenergic blockers, procainamide, lidocaine, trimethaphan, lithium carbonate, magnesium salts, quinine, chloroquine, diethyl ether, isoflurane, desflurane, metoclopramide, terbutaline, chronically administered oral contraceptives, glucocorticoids, certain MAOIs, organophosphates, ecothiophate, and certain antineoplastics. Antagonized by anticholinergics.
Skeletal muscle relaxant (depolarizing).
Respiratory depression or apnea (may be prolonged), cardiac arrest, malignant hyperthermia, arrhythmias, bradycardia, tachycardia, hyper- or hypotension, hyperkalemia, increased intraocular pressure, increased intragastric pressure, muscle fasciculation, jaw rigidity, post-op muscle pain, rhabdomyolysis with possible myoglobinuric acute renal failure, excessive salivation, rash, hypersensitivity reactions; children: acute rhabdomyolysis with hyperkalemia, ventricular dysrhythmias and cardiac arrest (rare).
