Abstract 【Objective】To explore the effect of ultrasound-guided nerve block and general anesthesia combined for elderly lower limb fracture surgery. 【Methods】A total of 268 elderly patients who underwent lower limb fracture surgery were randomly divided into an observation group (using ultrasound-guided nerve block combined with general anesthesia, 134 cases) and a control group (using general anesthesia, 134 cases). Comparisons were made between two groups in terms of anesthesia effectiveness, dosage of anesthetic drugs, awakening time, removal time of laryngeal mask, pain visual analogue scale (VAS), and adverse reactions; The average arterial pressure (MAP), heart rate (HR), prothrombin time (PT), thrombin time (TT), and activated partial thromboplastin time (APTT) levels were compared between two groups at different time points.【Result】 The excellent anesthesia rate in the observation group was higher than that in the control group (P<0.05); The observation group used less anesthesia, had shorter awakening time and removal time of the laryngeal mask, and had lower postoperative VAS scores than the control group (P<0.05); There was no statistically significant difference (P>0.05) in the MAP and HR of the observation group at the insertion (T1), incision (T2), and removal (T3) of the laryngeal mask compared to before anesthesia (T0). The MAP and HR of the control group were significantly higher at T1, T2, and T3 than at T0, while the MAP and HR of the observation group were significantly lower at T1, T2, and T3 than those of the control group (P<0.05); The PT, TT, and APTT of the observation group were significantly higher than those of the control group at time points T2 and T3 (P<0.05); The total incidence of adverse reactions in the observation group was lower than that in the control group (P<0.05).【Conclusion】 Ultrasound guided nerve block combined with general anesthesia has a relatively small impact on hemodynamics in elderly patients undergoing lower limb fracture surgery, better anesthesia effect, stable signs during surgery, and high clinical application value.
