Abstract: HTML Purpose: To evaluate the effectiveness of intra-arterial infusion of dilute lidocaine for providing pain relief during UFE. Methods and Materials: 87 patients underwent UFE. 58 were given a diluted Lidocaine solution with 40mg in 6.0 ml and 29 patients(control group) received a saline solution 5.0 ml through the catheter after polyvinyl alcohol (PVA) embolization and before injection of 1 to 3 gelfoam sticks. All of the patients were hospitalized for at least 3 days after the procedure. A questionares was collected by the attending residents to record the vasospasm, patient pain numeric rating scale score from the beginning of the procedure through three days after procedure. The acute post-operative pain and other symptoms were recorded and compared. The patients were followed-up by a contrast CT scan after 6 months. Results: Compared with control group, local intra-arterial anesthesia protocol with dilute lidocaine for UFE yielded good results for pain relief during and after the procedure. No interfering side effect was observed during the procedure. The patients in the lidocaine group experienced slight pain after UFE and no morphine was required. In the pain scale statistical results, there is a siginificant difference between two groups (p<0.01). Menorrhagia and bulk symptoms improved equally in both groups and the fibroid and uterine size were lessened in a 6 month follow-up in all of the patients. Conclusion: Intra-arterial use of diluted Lidocaine solution in UFE, can dramatically relieve the pain during and after the procedure. This improved UFE protocol is a simple approach to prevent the post-operative pain with good results.     Questions about this event email: zhansonghua@sina.com.cn
