Description
Feng Feng and co-authors compare nerve block timing in weight-loss surgery in a 2026 look-back study. The block numbs the spine-side nerves to cut pain after a sleeve stomach cut. Blocks can go in before the cut or after it. The team read records for patients who got the block at one of those times from one site in 2025, then matched the groups by traits.
After matching, 233 patients stayed in the pool. Day-one opioid use was much the same in both groups. Time to first rescue pain drug, sickness rates, first walk time, and stay length also matched. Timing, within a mixed pain plan, did not move results.
