Prevalance of peri-anesthesia allergy and its related risk factor: a retrospective survey from 2012-2017 / 北京大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the incidence of peri-anesthesia allergy in a tertiary teaching hospital.@*METHODS@#This was a retrospective cohort study. Patients who received anesthesia in operation rooms at Peking University First Hospital from January 2012 to April 2017 were enrolled. Researchers reviewed all the patients' electronic records and screened suspect allergy cases. Allergy was diagnosed according to the definition in Consensus on Management of Perioperative Allergy (China) and Scandinavian Clinical Practice Guidelines on the Diagnosis, Management and Follow-up of Anaphylaxis during Anesthesia. After obtaining the electronic records, two researchers began to screen and supplement missing data according medical records independently, then they checked out each other's data. The final data were reviewed by another two researchers. We collected the patients' basic characteristics, surgery type, anesthesia type, peri-anesthesia use of drugs, prognosis and other data. Univariate logistic regression was employed to screen potential factors of allergy. Factors with statistical significance (P<0.05) in univariate Logistic regression were entered into multivariate Logistic regression to identify independent risk factors of allergy.@*RESULTS@#In the study, 106 074 patients entered final statistic analysis. The incidence of peri-anesthesia allergy was about 1.5/1 000 (156/106 074). The incidence of Grades I, II and III allergy was 64.1% (100/156), 30.1% (47/156), and 5.8% (9/156) respectively. Multivariate logistic regression showed 5 independent risk factors of allergy including history of allergy (OR=6.836, 95%CI 4.461-10.474, P<0.001), intraoperative use of sufentanil (OR=1.993, 95%CI 1.228-3.232, P=0.005), intraoperative use of cis-atracuronium (OR=2.495, 95%CI 1.599-3.893, P<0.001), intraoperative infusion of antibiotics (OR=2.005, 95%CI 1.375-2.924, P<0.001) and frozen fresh plasma (OR=3.055, 95%CI 1.842-5.068, P<0.001).@*CONCLUSION@#The incidence of peri-anesthesia allergy is high and further attempt is needed to establish standard operation process of diagnosis and treatment of allergy.
