What is the most common cause of an allergic reaction during general anesthesia?

The most common cause of an allergic reaction during general anesthesia is related to nondepolarizing neuromuscular blockers. These agents are widely utilized in anesthetic practice to facilitate intubation and provide muscle relaxation during surgery. While they are essential for many surgical procedures, they can also induce anaphylactic reactions in some patients due to their quaternary ammonium structure, which presents an allergic potential.

It’s crucial to recognize that allergic reactions can manifest through a variety of symptoms, ranging from mild cutaneous reactions to more severe systemic responses. The prevalence of allergic reactions associated with nondepolarizing neuromuscular blockers highlights the importance of thorough pre-anesthetic assessments and awareness of potentially sensitive individuals.

Other agents like opioids, antibiotics, and latex also pose risks for allergic reactions, but the specific incidence of reactions linked to nondepolarizing muscle relaxants is notably higher in the context of general anesthesia. This understanding underscores the significance of monitoring and managing all possible allergens during the anesthetic process.
