    General Discussion
    Pseudocholinesterase deficiency is an uncommon genetic disorder that makes an affected person very sensitive to any of several anesthetic agents, especially those derived from the drug known as choline. When anesthetic drugs such as succinylcholine or mivacurium are administered to a susceptible person, the muscles that work the lungs may become paralyzed. Mechanical ventilation is essential until the excess anesthetic agent is metabolized and normal breathing is resumed.
