Succinylcholine apnea is identified by a blood test. There is a genetic defect that causes a lack of the enzyme that breaks down succinylcholine, a type of anesthesia. When succinylcholine is given to a person with this defect, it continues to suppress breathing long after the general anesthesia has worn off. For treatment the person is put on a ventilator and given fresh frozen plasma. Family members should be tested and have genetic counseling. Anyone who lacks this enzyme is at lifelong risk with succinylcholine. They should wear some type of identifying tag, such as a bracelet or necklace, with this information.
