Mivacurium chloride and myotonic dystrophy
British Journal of Anaesthesia
|October 1, 1995
Summary
Mivacurium, a neuromuscular blocking agent, was safely used in a patient with myotonic dystrophy. The patient showed increased sensitivity and prolonged recovery, avoiding reversal agents.
Area of Science:
- Anesthesiology
- Neuromuscular Disorders
Background:
- Myotonic dystrophy presents unique challenges for anesthesia management.
- Non-depolarizing neuromuscular blocking agents require careful titration in these patients.
Observation:
- A patient with myotonic dystrophy received mivacurium, a short-acting neuromuscular blocker.
- Train-of-four monitoring indicated increased sensitivity to the drug.
Findings:
- A single dose of mivacurium provided adequate neuromuscular block for 90 minutes of surgery.
- Spontaneous recovery was prolonged, with a recovery index of 10 minutes and recovery time of 30 minutes.
- Reversal and anticholinergic agents were not required.
Implications:
- Mivacurium can be used cautiously in myotonic dystrophy patients.
- Close neuromuscular monitoring is crucial for dose adjustment and recovery assessment.
- Avoiding reversal agents may be possible, simplifying anesthetic management.

01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

01:17Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

01:28Depolarizing Blockers: Mechanism of Action
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because succinylcholine...

01:26Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...

01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
