The effect of neostigmine on suxamethonium induced neuromuscular block in the dog.
The effects of neostigmine on suxamethonium induced neuromuscular block were investigated in the intact, anaesthetised dog using the train-of-four twitch to record neuromuscular activity. Marked antagonism of the block was observed when the train-of-four ratio was 0.38 and less. To avoid potentiating the block, the use of neostigmine is not recommended without first determining the state of neuromuscular activity with a peripheral nerve stimulator using train-of-four stimulation.
