salicylic acid + ESP block

The name "salicylic acid + ESP block" appears to be a misinterpretation of "SA + ESP" (Spinal Anesthesia + Erector Spinae Plane block), an anesthetic regimen being studied by the Hospital for Special Surgery (HSS). In the context of the Phase 3 clinical trial NCT05483400, researchers are comparing the efficacy of an Erector Spinae Plane (ESP) block combined with either spinal anesthesia (SA) or general anesthesia (GA) for patients undergoing lumbar decompression surgeries, such as those for lumbar disc herniation, lumbar disc disease, or lumbar radiculopathy. Salicylic acid is a salicylate nonsteroidal anti-inflammatory drug (NSAID) that provides analgesia by inhibiting cyclooxygenase enzymes. The ESP block is a regional anesthetic technique where local anesthetics (such as bupivacaine or mepivacaine) are injected into the fascial plane deep to the erector spinae muscle to provide multi-dermatomal sensory blockade, aiming to improve postoperative pain management and reduce opioid consumption.
