Background and Aims The appearance of sudden intense pain, after a peripheral nerve block ceases, is kown as Rebound Pain (RP). The reported frequency is described as between 40-60%. To reduce its occurrence, the use of adjuvants and the use of perineural catheter have been described. Dexamethasone, both perineural and also intravenously, reduces the incidence of RP. The risk decreases to approximately 10-20%. The methodology of studies using continuous technique has not allowed us to further clarify the benefit of their use. Our objective was to measure the incidence of RP in patients undergoing shoulder rotator cuff surgery with the use of home perineural catheters in our postoperative ambulatory REDCAP registry.
Methods The study has ethics committee approval. A review of REDCAP was carried out from January 1, 2020 to December 31, 2023, extracting data from patients with a diagnosis of rotator cuff tear. Pain >7 on a scale of 0-10 was considered rebound pain.
Results 495 patients were identified. 58 were lost to post-discharge follow-up (11.7%). Among the remaining 437 patients, 81 (18.5%) reported pain >7 at least once. On first postoperative day, 26 (5.7%). On 2nd postoperative day, 33 patients (7,8%) At the end of the infusion, 5,8% of patients reported rebound pain according to the work definition.
Conclusions These results are lower (not staistacally comparable) than those described with a single injection after 24 hours with or without adjuvants. It is interesting to know that the phenomenon can also occur after 48 and a60 hours when the blockade ends.
