Abstract
Seven patients underwent microwave ablation of hepatic tumors; during ablation, a hepatic nerve plexus block was used for pain control. The mean visual analog scale (VAS) score for pain (scale, 0-10) was 0.3 ± 0.5 (SD) at baseline and 2.5 ± 1.4, 2.6 ± 1.4, and 2.3 ± 0.9 at 1, 5, and 10 minutes during ablation. Two patients reported a VAS score of 4 or greater during ablation, which improved in both patients to a VAS score of 3 after one rescue sedation dose. The remaining patients required no additional sedation. No major complication occurred. No patient required conversion to general anesthesia.
