Web12 Nov 2024 · Using an in vivo post-tetanic potentiation method (one twitch contraction followed by a tetanic contraction—100 Hz for 1,000 ms with 0.01 ms pulses, and two post-tetanic twitch contractions), we investigated twitch torque potentiation in C57BL/6 young and old, male and female mice. WebThe post-tetanic count (PTC) has been used to assess the level of profound neuromuscular block-ade with atracurium [4]. As post-tetanic facili-tation is a presynaptic phenomenon [5] and as neuromuscular blocking drugs have different presynaptic effects [6], PTC is unlikely to relate precisely to intensity of paralysis for all agents.
