| Abstract: | Study objectivePerioperative allergic reactions (POHs) are common and can lead to severe intraoperative instability and even mortality. In contrast to the situation in developed countries, where databases of perioperative anaphylaxis are well documented and analyzed, relevant data are lacking in China. Therefore, we aimed to conduct a national survey to explore the characteristics of perioperative allergic reactions, as well as the knowledge and attitudes toward management and reporting among anesthesiologists.DesignCross-sectional survey.SettingAnesthesia department.PatientsA nationally representative sample comprising anesthesiologists from 12 province-level regions was selected.MeasurementsA 20-item questionnaire was designed and validated using the Delphi method. Survey distribution was performed between June 2019 and January 2020 by the Chinese Society of Anesthesiology (CSA), which is the official academic society of Chinese anesthesiologists. Responses were compiled and analyzed.Main resultsWe received responses from 4389 anesthesiologists across China. The estimated rate of suspected POH was 2/1000 patients (0.2%). On average, an anesthesiologist encountered 2.1 suspected POH cases per year. Neuromuscular blocking agents (NMBAs) were perceived as the most common causative agents, followed by antibiotics and succinylated gelatin. The rates of referral and allergy consultations were very low. Institutional support, including protocol development, cognitive aids, and tool kits, was not ideal. Additionally, the management of POH varied substantially. Most anesthesiologists believed that reporting and documenting POH was necessary.ConclusionsOur survey revealed that POH is commonly encountered by Chinese anesthesiologists, but few patients are referred to allergy specialists or clinics for further investigation. A standardized recommendation based on research and data derived from Chinese patients is required. |
