According to the World Allergy Organization (WAO) Anaphylaxis Guidance 2020, anaphylaxis is defined as “a serious systemic hypersensitivity reaction that is usually rapid in onset and may cause death.” 1 Severe anaphylaxis is characterized by potentially life-threatening compromise in the airway, breathing, and/or circulation. 1 Moreover, anaphylaxis may occur without typical skin features or cardiovascular shock being present. 1 The primary pathogenesis of anaphylaxis is an immediate immunoglobulin (Ig) E-mediated allergic

Life-threatening anaphylactic reactions are rare events in anesthesia. It is estimated that the incidence of allergy under anesthesia is 1:6000 to 1:20,000 but is most likely underreported in the literature with suboptimal accuracy, completeness, and varying reporting protocols. 1 – 5 It is well known that muscle paralyzers are the most commonly implicated agent with anaphylaxis under general anesthesia. 6 However, the patient is exposed to a wide variety of anesthetic, surgical, and supportive agents in the operating theater. As such, not

discharge of secretions from the previously placed orogastric tube) signs suggestive of an allergic reaction, although other cutaneous and oral signs, such as erythema, urticaria, and intraoral edema, were not observed. He was clinically diagnosed with anaphylaxis, intravenous boluses of epinephrine (initial dose 50 μg; subsequent doses 25 μg × 6 times; total dose 200 μg) were administered, and his vital signs then stabilized. Further dental treatment under general anesthesia was deferred at that time, and a subsequent blood test revealed elevated β-tryptase levels

Figure 3.; Changes in Blood Concentrations of Histamine and Tryptase After the Onset of Anaphylaxis When anaphylaxis occurs, mast cells and basophils release histamine and tryptase. To diagnose anaphylaxis, blood samples should be collected at 2 times: the onset of anaphylaxis and after 24 hours. Histamine and tryptase levels should be compared.

Changes in Blood Concentrations of Histamine and Tryptase After the Onset of Anaphylaxis

When anaphylaxis occurs, mast cells and basophils release histamine and tryptase. To diagnose anaphylaxis, blood samples should be collected at 2 times: the onset of anaphylaxis and after 24 hours. Histamine and tryptase levels should be compared.

Management of Anaphylaxis in the Dental Office

Anaphylaxis should be recognized at an early stage, epinephrine should be administered intramuscularly, and the patient should be transported immediately to a hospital.

*Implement steps 3–5 promptly and simultaneously. 1

Anaphylactic shock, a severe complication during general anesthesia, is a rapidly occurring severe allergic reaction that may be fatal. Causative agents include drugs, foods, insects, latex, and even exercise. The incidence of allergic reactions due to drugs is 1% to 3% of exposures, but the frequency of anaphylaxis is much lower. 1 The frequency of anaphylaxis during general anesthesia has been reported to be between 1:5,000 and 20,000 cases. Muscle relaxants are the most common causative drugs during general anesthesia, and it is

The mechanism was attributed to a common metabolite, desmethyldiazepam, the antigenic moiety for cross-allergenicity in benzodiazepines. 6 Years later, 1 report of diazepam allergy describes a case involving a healthy 28-year-old nurse with no significant past medical history or allergies presenting for gastroscopy. Here, a relatively brief and nonspecific case of hypersensitivity was reported including only that the patient showed signs of “generalized

In 2020, the World Allergy Organization Anaphylaxis (WAOA) Guidance document was published that updated the definition of and amended the criteria for diagnosing anaphylaxis ( Table ). The WAOA definition now reads as follows: “Anaphylaxis is a serious systemic hypersensitivity reaction that is usually rapid in onset and may cause death. Severe anaphylaxis is characterized by potentially life-threatening compromise in airway, breathing and/or the circulation, and may occur without typical skin features or circulatory shock being present.” 1

Basophil activation test (BAT) results. Activated basophil counts for the negative control (2.8%), positive control (35.2%), flomoxef (2.2%), rocuronium (3.2%), and rubber dam sheet (54.7%) challenges. Stimulation of naïve basophils with the rubber dam sheet elicited a strong positive result (1-hour contact; sample concentration, 1/1250). Evaluation criteria for activated basophils were as follows: <6% negative, 6–10% false-positive, 10–15% weakly positive, 15–20% positive, and >20% strongly positive.
