بلوک گانگلیون ریشه پشتی کمری به عنوان یک ابزار پیش آگهی قبل از رادیو اکتیو پالس: مطالعات تصادفی، آینده نگر و مقایسه ای در مورد هزینه-اثربخشی

In this comparative cost-effectiveness study, the application of diagnostic DRG blocks before DRG-PRF did not have a significant impact on patient satisfaction, pain index score, or pain medication reduction. Furthermore, the application of diagnostic DRG blocks resulted in overall greater medical costs. These findings suggest that DRG-PRF without screening by DRG block is more cost-effective and less invasive.
