Dental Treatment Under General Anesthesia With Nasal Intubation in a Patient With Selective Immunoglobulin A Deficiency.

Immunoglobulin A (IgA) deficiency is one of the most common immune disorders characterized by increased susceptibility to infections, especially involving the respiratory tract and mucosal surfaces of the mouth, gingiva, and nasal sinus. Because dental surgery and general anesthesia may pose an increased risk for systemic infections, management of IgA-deficient patients requires caution during dental procedures and intubated general anesthesia. We report a 5-year-old female patient with IgA deficiency who underwent extraction of 18 deciduous teeth under general anesthesia. Antibiotic prophylaxis and antiseptic mouthwash were used perioperatively to reduce bacteremia risks. Nasotracheal intubation was carefully performed after applying topical disinfectants and epinephrine-containing gauze packing into the nasal cavity to minimize trauma. The patient was carefully monitored overnight in the hospital and discharged without any signs or symptoms of infection the next day. Dental anesthesia providers must be aware of the potential implications for safe practice when managing patients with IgA deficiency.
