Emergency Preparedness for Duchenne Families

The emergency room is exactly where Duchenne muscular dystrophy is most likely to be misunderstood. The staff are competent, but they are general-purpose, and DMD carries specific risks that an unprepared team can miss: adrenal crisis from interrupted steroids, dangerous reactions to certain anesthetics, and a heart that may be more fragile than the patient looks. Preparation is what turns an emergency from dangerous into manageable.

This post is a practical guide to being ready before the emergency happens.

Why DMD needs an emergency plan

A child or adult with DMD who arrives at an unfamiliar hospital presents three hidden risks at once.

First, adrenal suppression. Patients on long-term corticosteroids cannot abruptly stop them, and illness, injury, or surgery may require extra “stress dose” steroids to prevent a life-threatening adrenal crisis.

Second, anesthesia and medication risk. Succinylcholine and volatile anesthetics can trigger dangerous reactions. For more, see anesthesia safety in DMD.

Third, cardiac and respiratory fragility. Cardiomyopathy may be present even without symptoms, and reduced respiratory reserve changes how fluids, sedation, and oxygen should be managed. See heart care in DMD and respiratory care in DMD.

A staff member who does not know these facts cannot account for them. The plan exists to tell them, fast.

The emergency card

The single most useful tool is a concise emergency information card that travels with the patient. Parent Project Muscular Dystrophy and other organizations provide ready-made versions: a wallet card, a weatherproof card that clips to a wheelchair, and digital app versions. (Parent Project Muscular Dystrophy, Emergency Care)

A good emergency card states, at minimum:

• The diagnosis (Duchenne muscular dystrophy) and the patient’s current function.
• Current corticosteroid and the need for stress dosing in illness or injury.
• Anesthesia precautions: avoid succinylcholine and volatile agents.
• Cardiac status and current cardiac medications.
• Respiratory status, including any nighttime ventilation.
• Contact details for the patient’s neuromuscular team.

The card should be somewhere a stranger will find it: wallet, phone lock screen, wheelchair, and a magnet on the fridge at home.

Steroid stress dosing

This is the precaution most often missed by general emergency staff. Patients on long-term glucocorticoids may have a suppressed adrenal response and cannot mount the cortisol surge that illness or trauma demands.

The PJ Nicholoff Steroid Protocol was developed specifically to guide clinicians on recognizing adrenal crisis, giving supplemental stress-dose steroids, and tapering safely afterward in Duchenne and Becker muscular dystrophy. (PJ Nicholoff Steroid Protocol, PMC)

Families benefit from carrying a copy or a link to this protocol, because it gives the emergency team concrete, citable instructions rather than a general statement that “steroids matter.”

Signs of adrenal crisis can include severe weakness, vomiting, abdominal pain, confusion, low blood pressure, and collapse. These are an emergency and require immediate stress-dose steroids, usually hydrocortisone given by injection or IV.

Briefing a hospital that does not know your child

When you arrive, assume the team knows nothing specific about DMD. A calm, structured handover helps:

• State the diagnosis and hand over the emergency card immediately.
• Name the three priorities: steroid stress dosing, anesthesia precautions, cardiac and respiratory caution.
• Ask that the patient’s neuromuscular team or a dystrophinopathy-experienced physician be contacted. (Parent Project Muscular Dystrophy, Emergency Care)
• Mention current medications, allergies, and baseline cardiac and respiratory function.

Writing these down in advance, so they can be handed over even when the family is frightened or exhausted, is the point of preparation.

A practical go-bag

Families who have been through it often keep a prepared kit:

• Printed emergency card and a copy of the steroid protocol.
• Current medication list with doses.
• Recent cardiac and respiratory summaries if available.
• Neuromuscular team contact details.
• The patient’s own ventilation or cough-assist equipment settings, if used.
• Comfort items for what may be a long wait.

Keeping this ready removes a layer of panic from an already hard moment.

Planning ahead with the care team

Emergency preparedness is best set up during a calm clinic visit, not improvised. Families can ask the neuromuscular team to help complete an emergency card, provide a copy of the steroid protocol, document cardiac and respiratory baselines, and clarify what counts as an emergency for that specific patient.

Schools, respite carers, and extended family who spend time with the patient should know where the card is and what the three priorities are.

What is still uncertain

Emergency protocols evolve, and specifics depend on the individual patient’s steroid regimen, cardiac and respiratory status, and local hospital systems.

The reasonable framing is that most DMD emergencies are far safer when the team is briefed quickly and accurately. Preparation is the cheapest and most effective safety measure a family can put in place.
