Abstract:Objective To analyze the adverse reactions and their risk factors associated with Xiyanping Injection in the treatment of pediatric intestinal infections.Methods A retrospective analysis was conducted on the medical records of 200 children treated with Xiyanping Injection for intestinal infections at Dazhou Integrated TCM and Western Medicine Hospital from August 2020 to August 2024. The incidence, onset time and outcome of adverse reactions were analyzed. Univariable and multivariable Logistic regression analyses were used to evaluate the related risk factors.Results Among the 200 children, 64 (32%) experienced adverse reactions. The majority of the adverse reactions occurred within 5 minutes after administration (39.06%). Among the clinical manifestations of adverse reactions, 20 cases (31.25%) involved the skin and its appendages, 15 cases (23.44%) presented with systemic disorders, 11 cases (17.19%) affected the respiratory system, 10 cases (15.63%) involved the central nervous system, 5 cases (7.81%) were related to the gastrointestinal system, and 3 cases (4.69%) involved the cardiovascular system. A higher incidence of adverse reactions was observed in children under 3 years old, those administered with excessive doses, receiving combination therapy, undergoing intravenous infusion at a rate of 80 drops/min, using 0.9% sodium chloride injection as the solvent, and those with a documented history of allergies (P < 0.05). Multivariable Logistic regression analysis revealed that age < 3 years [O^R = 3.083 (95% CI: 1.529, 6.218) ], overdose administration [O^R = 2.528 (95% CI: 1.217, 5.249) ], combination therapy [O^R = 2.654 (95% CI: 1.215, 5.797) ], intravenous infusion [O^R = 2.583 (95% CI: 1.174, 5.684) ], infusion rate of 80 drops/min [O^R = 2.037 (95% CI: 1.007, 4.121) ], use of 0.9% sodium chloride injection as the solvent [O^R = 2.114 (95% CI: 1.053, 4.247) ], and a history of allergy [O^R = 3.062 (95% CI: 1.496, 6.269) ] were risk factors for adverse reactions (P < 0.05).Conclusion Age, dosage, combination therapy, route of administration, infusion rate, solvent type and history of allergy are the major risk factors for adverse reactions in children receiving Xiyanping Injection for intestinal infections. Early assessment and monitoring should be conducted for high-risk children, and appropriate preventive measures should be taken to ensure the safe and effective use of Xiyanping Injection.
