Question

If the patient displays increased muscle weakness, this is an adverse effect of the tubocurarine, and respiratory depression may ensue. A dopamine antagonist would not be indicated to reverse the effects of the tubocurarine. Ganglionic blockers interrupt impulse transmission through ganglia of the autonomic nervous system; they are nonselective and no longer have therapeutic uses. A neuromuscular blocking agent would increase muscle paralysis and make the condition worse.
