Abstract：Objective To investigate the effect of normal saline on skin wiping before cephalosporin antibiotic allergy test. Methods A total of 500 patients who underwent cephalosporin antibiotic allergy test in the Department of Lower Extremities of Sichuan Provincial Orthopaedic Hospital from September 2016 to March 2017 were randomly divided into experimental group and control group, with 250 cases in each group. The experimental group was cleaned with physiological saline before the cephalosporin antibiotic allergy test; the control group was directly disinfected with 75% alcohol. The cephalosporin antibiotic allergy test results and bacteriological test results of the two groups of patients were compared. Results The false positive rate of the experimental group was significantly lower than that of the control group, and the difference was statistically significant (P < 0.05). There were no bacterial test failures in both groups, and the sterility pass rate was 100.00%. Conclusion The use of saline for skin cleansing in cephalosporin antibiotic allergy tests can effectively reduce the incidence of false positives in cephalosporin allergy tests.
