Pseudocholinesterase deficiency is an inherited blood plasma enzyme abnormality in which the body's production of butyrylcholinesterase (BCHE; pseudocholinesterase) is impaired. People who have this abnormality may be sensitive to certain anesthetic drugs, including the muscle relaxants succinylcholine and mivacurium as well as other ester local anesthetics.
