经股神经长轴髂筋膜阻滞在老年髋部骨折患者镇痛中的应用OA

Objective To explore the application effect of ultrasound-guided long axis iliac fascia block through femoral nerve for pain management in elderly patients with hip fractures.Methods A total of 60 elderly patients with hip fractures admitted to the Second Affiliated Hospital of Jiaxing University from March to June 2023 were selected,and they were divided into S group and L group according to random number table method,with 30 cases in each group.Patients in S group underwent short axis iliac fascia block through femoral nerve by ultrasound,while patients in L group underwent long axis iliac fascia block through femoral nerve by ultrasound.The static numerical rating scale(NRS)scores,dynamic NRS scores of two groups were compared before nerve block(T0),and 10min(T1),2h(T2),6h(T3)and 12h(T4)after nerve block,effective cases of nerve branch block,and occurrence of adverse events related to nerve block were compared between two groups.Results The static and dynamic NRS scores of two groups decreased first and then increased slightly with the extension of time.At time points T2 and T3,the static and dynamic NRS scores of patients in L group were significantly lower than those in S group(P<0.05).The effective cases of lateral femoral cutaneous nerve block and obturator nerve block in L group were significantly higher than those in S group(P<0.05).No adverse events such as local anesthetic poisoning,peripheral nerve injury,and analgesia covering up the disease occurred in both groups.Conclusion Ultrasound-guided long axis iliac fascia block through femoral nerve can effectively reduce early pain in elderly patients with hip fracture,and it is safe.
