title: Effect of plasma-cholinesterase preparation on the phase II block of succinylcholine chloride in man.
abstract: The effect of enriched human plasma-cholinesterase preparation on the phase II block of succinylcholine chloride was studied in man during anesthesia and surgery. Intravenous administration of 8 esterase units/kg of plasma-cholinesterase did not show any discernible effect on the phase II block of succinylcholine chloride, while edorphonium 10 mg clearly antagonized the block. The finding of the present study suggests that the preparation may be ineffective for patients with a prolonged apnea following the administration of succinylcholine chloride.
