Objective This study is designed to explore the indications, clinical pathway, and benefits of ultrasound-guided local anesthesia in radiofrequency endovenous obliteration (RFO) for great saphenous vein varices (GSV).Methods A total of 350 patients diagnosed with GSV were divide into observation group (n=175) and control group (n=175). Patients in the observation group underwent local anesthesia RFO, and patients in the control group underwent intravertebral anesthesia. Comparion in the visual analogue scale pain scores (VAS) when anesthesia and after surgery, operative indexes, recovery time, satisfaction, and complications were performed.Results Compared with the control group, the VAS score with anesthesia time were lower (P<0.05), while in the surgery were higher (P<0.05), as well as the operative time, the first time for underground activity, normal activity time, incidences of complication of anesthesia and urinary were shorter (P<0.05), and the satisfaction rate was higher (P<0.05). There was no difference in the pain score of 12 h and 24 h after surgery, blood loss, volume of anesthetic swelling fluid, postoperative hospitalization, incidences of urinary tract infection, incisional infection, and deep vein thrombosis (P>0.05).Conclusions The RFO is feasible and safe after local anaesthesia. It can decrease the complication of anesthesia, that will promote the patient soon to be restored to health.
