The management of an undetected pseudocholinesterase deficiency in a parturient who underwent urgent cesarean section has been presented. After rapid sequence induction with succinylcholine, rocuronium was used for maintenance of neuromuscular block. At the end of the operation neostigmine was given to antagonize the residual block. Upon persistent prolonged neuromuscular blockade sugammadex was administered. Probable reasons, drug interactions, the importance of suspecting pseudocholinesterase deficiency and the need of neuromuscular monitoring have been argued in this case report.
