How does succinylcholine help in preventing bronchospasm?

Show Answers

By causing a depolarizing neuromuscular blockadeThrough direct relaxation of bronchial musclesBy inducing muscle relaxation via central nervous system effectsBy exhibiting a combination of multiple mechanismsNone of the above

Explanation

Succinylcholine prevents bronchospasm primarily by producing a depolarizing block at the neuromuscular junction. This action leads to muscle relaxation by continuously stimulating the motor endplate, thereby preventing sustained muscle contraction. It does not act directly on the muscles or through central nervous system pathways.
