This report describes the onset of respiratory paralysis 2 hours after retrograde pyelography with a contrast material containing 2.5% neomycin. Although calcium has been described as more effective in treatment of neomycininduced neuromuscular blockade, the condition responded promptly to intravenous neostigmine and positive-pressure respiration.
