Post Tetanic Count and Single Twitch Height at the Onset of Reflex Movement After Administration of Vecronium Under Total Intravenous Anesthesia

Abstract

We have studied post tetanic count (PTC) and single twitch height at the onset of reflex movement to carinal stimulation after administration of vecronium to 10 female patients under total intravenous anesthesia. During spontaneous recovery from vecronium-induced neuromuscular block, the carina was stimulated at every 120s. It took 18.7±5.5 minutes before reflex movement started, T1% was 1.9±2.2%, and PTC was 11.59±5.3 counts. In 5 cases, T1% did not appear at the onset of reflex movement.
