Anaphylactic reaction after local lidocaine infiltration for retraction of retained teeth

다국어 초록 (Multilingual Abstract)

Although allergic reactions are not rare complications in drug use, anaphylaxis or anaphylactoid reactions to some widely used drugs can embarrass clinicians because anaphylaxis is not easily diagnosed at the time of the event and treatment is unfamiliar to many. Lidocaine is a very popular drug in dental procedures and anaphylactoid reaction to it has been rarely reported. Clinicians who use lidocaine daily should, however, be aware of the possibility of anaphylaxis after its use. Once it occurs, anaphylaxis can be fatal, but if it is quickly diagnosed or suspected, treatment is simpler than most clinicians believe. An 86-year-old woman experienced an anaphylactic reaction 30 min after local infiltration of lidocaine for retraction of retained teeth. The dentist called an anesthesiologist for assistance. Fortunately, an anaphylactic reaction was quickly suspected and after subsequent rapid treatment with the administration of fluid and drug therapy, the patient recovered completely.
