Description
Boohwi Hong and co-authors test a steroid shot against rebound pain after arm nerve blocks in a 2026 study. Rebound pain, a sharp surge as a block wears off, troubles many patients after upper limb bone surgery. Records covered 1,171 patients, of whom 651, or 55.6 percent, received intravenous dexamethasone.
Rebound pain struck 7.1 percent of the steroid group against 16.9 percent without it, and onset came later, at a median of 14 hours against 11 hours in the comparison. Causal machine learning put the average benefit at a 9 percent absolute risk cut, steady across patient types with no clear subgroup differences. A single vein dose thus looks like a simple shield against a painful rebound.
