Objective To explore the use of agkistrodon halys antivenin, and the influence of its infusion time on the coagulation function of the patient bitten by agkistrodon halys. Methods We retrospectively analyzed the clinical data of patients suffering from pit viper bites and first diagnosed and treated in the emergency department of our hospital between April 1 and November 30, 2013. According to the allergy test results, patients were divided into two groups: negative and positive. Based on the infusion time, the negative patients were divided into ≤1.5 hours and >1.5 hours groups, and the positive patients were divided into ≤3 hours and >3 hours groups. All patients' gender, age, infusion time, and PT, APTT, TT, FIB, D-DIMER before and after infusion of antivenomous serum were recorded, and blood coagulation indicators before and after infusion of antivenomous serum and the impact of infusion time were compared among different groups. Results For both the negative and positive groups, PT, APTT, TT, FIB, and D-DIMER were statistically improved after infusion of antivenomous serum. The blood coagulation indicators of infusion time ≤1.5 hours group and ≤3 hours group were significantly better than those of infusion time >1.5 hours and >3 hours groups. Conclusion Antivenomous serum can correct coagulation and the faster infusion rate, the more obvious the effect is.
