Objective To investigate the anesthetic effect of ropivacaine nerve block under general anesthesia combined with B-ultrasound guidance in patients undergoing lower limb fracture surgery. Methods The study selected a control form and selected 56 patients treated in our hospital as the subjects of this study. All subjects were from lower limb fracture surgery patients registered between May 2024 and May 2025. According to the random number table method, the 56 patients were divided into two groups with different anesthesia methods. The control group of 28 patients only received general anesthesia, while the observation group of 28 patients received general anesthesia combined with B-ultrasound guided ropivacaine nerve block. The postoperative pain, time indicators, incidence of adverse reactions, and satisfaction scores of the two groups of patients were compared. Results In the observation group, the use of general anesthesia combined with B-ultrasound guided ropivacaine nerve block can effectively shorten various time indicators (P<0.05); The pain relief of the observation group patients was faster at various time points after surgery (P<0.05); General anesthesia combined with B-ultrasound guided ropivacaine nerve block can effectively reduce the incidence of adverse reactions (P<0.05); Patients in the observation group were more satisfied with the combination of general anesthesia and B-ultrasound guided ropivacaine nerve block (P<0.05). Conclusion The combination of general anesthesia and B-ultrasound guided ropivacaine nerve block has a significant anesthetic effect in patients undergoing lower limb fracture surgery. It can effectively shorten the patient's recovery time, extubation time, and directional force recovery time, reduce the incidence of adverse reactions and postoperative pain at various time periods. Moreover, patients are more satisfied with this surgical method, which is worthy of clinical promotion and use.
