[Analysis of Injection of Xuesaitong (lyophilized) in 30097 cases in real world].

To investigate the extensive application of Injection of Xuesaitong(lyophilized) in clinical real world study, and provide basis for clinical guidance on rational drug use and improvement of drug instructions. A prospective, multi-center, large-sample hospital centralized monitoring method was adopted to collect the general information and medication information of all patients who received Injection of Xuesaitong(lyophilized) during the study period in the respective monitoring units. Data analysis was performed using SAS 9.1 software. This study included 79 hospitals, with 30 097 patients being recruited. The patients who met the indications for stroke and hemiplegia accounted for 31.18%, those who experienced indications of chest pain and heartache accounted for 23.15%, and patients with central retinal vein occlusion indication accounted for 0.53%. The minimum single dose of Injection of Xuesaitong(lyophilized) was 20 mg, the maximum single dose was 1 000 mg, and the average single dose was(383.31±78.10) mg. 69.96% of the patients used 0.9% sodium chloride as the menstruum, 28.78% of the patients used 5% glucose as the menstruum, and 0.19% of the patients used 10% glucose as the menstruum. The minimum time for Injection of Xuesaitong(lyophilized) to dissolve is 0 min, 120 min maximally, and(14.26±13.73) min on an average basis. Patients using Injection of Xuesaitong(lyophilized) by intravenous drip accounted for 99.93%, with a slowest drip rate of 10 drops per min, fastest drip rate of 80 drops per min, and an average of(43.91±10.77) drops per min. Injection of Xuesaitong(lyophilized) was used for a minimum of 1 day and a maximum of 80 days, with an average of(8.22±5.12) days. Combined use with other injections accounted for 80.67%, 47.14% of them flushed the tube and 3.31% of them replaced infusion sets. The study found 40 cases of adverse reactions in patients with Injection of Xuesaitong(lyophilized), with an overall incidence of 0.13%(0.09% to 0.17%) for adverse reactions. In the real world application, the usage of Injection of Xuesaitong(lyophilized) basically meets the requirement of drug instructions in terms of indications, dosages, and methods of administration. However, it still needs to be improved in standardizing the selection of the menstruum, drip rate, course of treatment, and the combined usage of medicine.
