BackgroundTo investigate if intra-arterial lidocaine administrated immediately after the embolisation endpoint reduces the pain.MethodsForty patients were randomised and 36 completed the study for purposes of analysis. In one group, the patients got 1% 10 ml lidocaine (100 mg) administered into each uterine artery immediately after embolisation with microspheres. The other group was embolised without supplementary lidocaine. The patients scored their pain on a visual analogue scale (VAS) 2 h, 4 h, 7 h, 10 h and 24 h after embolisation, and the total amount of used morphine was noted. Three-month follow-up MRI control was scheduled for all the patients to investigate the infarction rate.ResultsEmbolisation was performed without any complications and with embolisation of both uterine arteries in all cases. Intra-arterial lidocaine was administered in all 20 patients without complications, and 20 patients in a control group did not receive lidocaine intra-arterial. VAS schemes showed a significant reduction in pain experience 2 h after UFE where mean pain score in the lidocaine group was 42.7 ± 21.4 compared with the control group in which the mean pain score was 61.1 ± 20.4 (p < 0.02). There was no significant difference in pain score 4 h, 7 h, 10 h and 24 h after UFE. In the lidocaine group, the mean amount of used morphine was significantly less with 11.2 mg compared with 20.2 mg in the control group (p < 0.03). Three months of MR follow-up control showed no significant difference in the grade of fibroid infarction.ConclusionIntra-arterial Lidocaine administration after embolisation is safe and effective in reducing post-procedural pain in the early hours and opioid usage in the first 24 h following UAE.
