Comparing the Effectiveness of Betamethasone and Triamcinolone Acetonide in Multimodal Cocktail Intercostal Injection for Chest Pain After Harvesting Costal Cartilage: A Prospective, Double-Blind, Randomized Controlled Study.

Background: There has been no previous study on the availability of different glucocorticoid varieties used in the multimodal cocktail for harvesting autologous costal cartilage. This randomized controlled trial (RCT) was to compare the significance and complications of betamethasone and triamcinolone acetonide as a component of the cocktail for harvesting costal cartilage in patients.

Materials And Methods: The patients were randomized to two groups. The group A used multimodal cocktail: ropivacaine, parecoxib sodium, epinephrine, and triamcinolone acetonide; group B used multimodal cocktail: ropivacaine, parecoxib sodium, epinephrine, and betamethasone. The primary outcomes were chest pain after surgery evaluated with a visual analog scale (VAS). The secondary outcomes evaluated the quality of recovery. The tertiary outcomes included rescue analgesic consumption, the first feeding time and the time to the first ambulation, and duration of hospital stay.

Results: The VAS scores between the two groups was not considered clinically significant, but the groups achieved a VAS score of 3 or less. However, the time until the first rescue analgesia and the number were significantly longer and smaller for group A. Additionally, there were no significant differences between the two groups in the duration of hospital stay, first feeding time, the quality of recovery, and the first ambulation time.

Conclusion: Adding corticosteroids into the multimodal cocktails could improve pain relief after costal cartilage harvest. And the efficacy of Triamcinolone acetonide was better than betamethasone.
