Objective investigate the clinical effect of the bracial plexus of the block of anesthesia conducted by B-ultrasound. Methods from November 2020 to March 2022, 80 patients treated at the hospitals orthopedic ministry were selected as an research subject for this experiment. They were randomly divided into two groups: reference group (n = 40) and research group (n = 40). Two groups were intervened with different treatment methods. The reference group is conducted by standard surgery, and the study group is conducted by B-ultrasound. The onset and duration of anesthesia, analgesic effects, complication incidence, median arterial pressure and heart rate are compared between two groups. Results After intervention, the start of an anesthesia in the study group is (4.18 ± 1.05), the duration of anesthesia is (528.15 ± 22.05), an effective rate of anesthesia is (89.5%), greater than that in the reference group (72.1%), the incidence of complications is (2.15%) lower than that in the reference group (12.1%). The arterial pressure and heart rate were less than those in the reference group. Conclusion The clinical anesthetic effect of the Brazilian plexus block of anesthesia led by B-ultrasound is ideal. The position of anesthesia can be clearly found by ultrasound, suitable for anaesthetic surgery, decreased the start of anesthesia, continued anesthesia, played an important role in the operation process and can maintain the index of arterial pressure and heart rate, reduced complications is worth promoting.
