This study aimed to assess the efficacy of PRF combined with transverse abdominal plane (TAP) block for abdominal acute/subacute HZ-related pain.</p><p><strong>Methods: </strong>A total of 137 acute/sub-acute HZ patients with successful PRF treatment were recruited from the Pain Department of Wuhan No. 1 Hospital between January 2018 and January 2020. There were two groups: the transversus abdominis plane group (TAP group, n = 64) and the normal saline group (NS group, n = 60). Pain intensity, sleep quality, and quality of life were quantified using the visual analogue scale (VAS), the five-item questionnaire and scoring system, and the 36-item Short Form Health Survey (SF-36) questionnaire, respectively. Follow-up assessments were conducted at baseline, 1 day, 3 months, 6 months, and 12 months after the block therapy.</p><p><strong>Results: </strong>Compared to the NS group, the TAP group showed significantly decreased pain scores 1 day, 3 months, 6 months, and 12 months after block therapy (P < .05). The sleep quality scores were lower in the TAP group than that in the NS group at 6 months (5.0 ± 2.4 vs 6.3 ± 3.7, p = .042), and 12 months after therapy (3.1 ± 1.8 vs 4.1 ± 2.4, p = .031). For quality of life, in comparison to NS group participants, those in the TAP group exhibited significantly higher scores (p < .05) for quality of life at 3 months, 6 months, and 12 months follow-up. There was a significant decrease in the proportion of pregabalin and analgesic medications in the TAP group and NS group at 6 and 12 months after treatment compared to Baseline (p < .001). Furthermore, the results showed that there was a significant difference in VAS, sleep quality scores (SQS), and quality of life between the PRF + TAP group and pharmacological therapies group before and 12 months after treatment (p < .05).</p><p><strong>Conclusion: </strong>The TAP block is a promising complementary treatment for acute/subacute HZ patients who have undergone PRF treatment.
