Sickle Cell Disease (SCD) pain crises are the leading cause of hospitalization for affected children, causing excruciating vaso-occlusive episodes where misshapen blood cells block oxygen flow to tissues. For decades, the standard treatment has been high-dose opioids, but this often leads to tolerance, inadequate relief, and the dangerous paradox of opioid-induced hyperalgesia—where the treatment actually makes the nervous system more sensitive to pain.In this episode, we analyze a massive cross-sectional study from 44 U.S. children’s hospitals involving over 74,000 admissions. The study asks a critical question: Can ketamine, an NMDA receptor antagonist that "turns down the volume" on central sensitization, break the cycle of pain where opioids fail?The findings reveal a slow but steady rise in ketamine use (doubling from 2.3% in 2016 to 5.7% in 2023), mostly reserved for older children with severe disease markers like chronic pain or hydroxyurea use. But the most stunning insight is about timing. The study found that when ketamine was administered early (within the first 3 days of admission), it cut the median hospital Length of Stay (LOS) in half—from 12 days to just 6 days—and drastically reduced the days patients needed IV opioids.Despite these compelling results, huge gaps in care remain, with some hospitals using ketamine in 20% of cases and others in 0%. We discuss the institutional barriers, stigma, and red tape that prevent clinicians from using this powerful tool when it matters most: early in the crisis.Reference:Jenkins, A.
