Sickle Cell Crisis in the Field
Objective: Treat sickle cell pain as real. Screen for stroke, acute chest syndrome, and infection. Do not delay care because you suspect drug seeking, and do not put a non-rebreather on a talking patient with a normal saturation.
Why this matters
The patient wants pain medicine, and a crew member may treat that request as the whole call. The pain is still real. Sickled cells block small vessels. First, treat the pain as real and screen for stroke, acute chest syndrome, and infection. Do not delay care because you suspect drug seeking. Acute chest syndrome, stroke, and splenic sequestration need a short scene.
- Ask how this crisis compares with their usual one. New one-sided weakness is a stroke until proven otherwise.
- Give oxygen if they are hypoxic. Do not put a non-rebreather on a talking patient with a normal saturation.
- Treat fever plus sickle cell disease as infection until the hospital says it is not.
Clinical sequence
- Compare this episode with their usual crisis. A new focal deficit is a stroke pathway.
- Give oxygen for hypoxia or distress. Do not put a non-rebreather on a talking patient whose saturation is normal.
- Treat fever plus sickle cell disease as infection until proven otherwise, and transport.
- Treat pain per protocol. This page has no opioid dose. Screen for acute chest syndrome: chest pain and hypoxia can be acute chest syndrome, and fever may be present. Do not withhold pain medicine because of stigma.
Teaching points
- Vaso-occlusive pain. The pain comes from blocked small vessels. Give analgesia per protocol. Do not withhold it because of a drug-seeking label. Do not invent an opioid dose.
- Acute chest syndrome. Chest pain, fever, hypoxia, and later a new infiltrate. In the field, chest pain and hypoxia in sickle cell disease are the clue. Treat hypoxia and transport.
- Stroke. Children with sickle cell disease have strokes. Use your stroke pathway.
- Other emergencies. Priapism, and splenic sequestration in a child who is pale, has a large spleen, and is in shock, are destination problems.
Common errors
- Do not let a drug-seeking label delay care.
- Do not skip the neurologic exam.
- Do not withhold oxygen from a hypoxic patient in chest crisis.
Practice
One-minute check
A 16-year-old with sickle cell disease has new right-arm weakness. Say whether this is a pain-only call or a stroke pathway, and say why.

- NASEMSO National Model EMS Clinical Guidelines (2022) — U.S. EMS model language; your protocol still decides care
- NHLBI sickle cell disease — pain is real; watch for acute chest and stroke
- ACEP Emergency Department Sickle Cell Care Coalition — pain is real; do not delay analgesia for stigma
