title: Atracurium use in a patient with familial periodic paralysis.
abstract: We describe a patient with the hypokalemic type of familial periodic paralysis (FPP) who received atracurium for muscle relaxation as required for diagnostic laparoscopy. Electrocardiographic (EKG) T-wave changes suggestive of hypokalemia were not supported by blood determinations. Arterial blood measurements of potassium (K+), pH, and arterial carbon dioxide tension (PaCO2) and the patient's esophageal temperature were maintained within normal limits. The degree of muscle relaxation was closely monitored by a peripheral nerve stimulator and train-of-four (TOF) measurement of muscle twitch height. At the conclusion of the surgical procedure, no reversal to the muscle relaxant was needed or given. The patient regained preoperative muscle strength, and her postoperative course was uneventful.
