Rocuronium anaphylaxis in a 3-year-old girl with no previous exposure to neuromuscular blocking agents.

During the perioperative period, anaphylactic reactions rarely occur. Neuromuscular blocking agents (NMBAs) are responsible for 60-70% of perioperative anaphylactic reactions. This case, we report a case of rocuronium-induced anaphylaxis in a 3-year-old girl with no previous exposure to NMBAs. This case cautions and informs practitioners that an IgE-mediated anaphylactic reaction with rocuronium is possible even in young children with no previous exposure to NMBAs.
