Anesthesia Safety in Duchenne Muscular Dystrophy

Anesthesia in Duchenne muscular dystrophy requires specific precautions: succinylcholine is contraindicated because of hyperkalemic cardiac-arrest risk, volatile inhalational agents are best avoided because of rhabdomyolysis risk, and pre-operative cardiac and pulmonary assessment is part of routine planning. Total intravenous anesthesia, with regional techniques where appropriate, is the standard general anesthesia approach.

Most patients with DMD will need anesthesia at some point. Dental procedures, port placements, scoliosis surgery, gastrostomy, cardiac catheterization, and even minor outpatient procedures all involve sedation or general anesthesia. The risks are different in DMD than in the general population, and the precautions are specific.

This post is a practical overview for families. The actual plan belongs to an anesthesiologist familiar with neuromuscular disease, working with the rest of the DMD care team.

Why anesthesia is different in DMD

Dystrophin-deficient muscle responds abnormally to certain anesthetic agents. The two best-described risks are hyperkalemic cardiac arrest with succinylcholine and severe rhabdomyolysis with volatile anesthetics. The mechanisms differ from classic malignant hyperthermia but the clinical picture can overlap, which historically caused confusion.

DMD also affects cardiac and respiratory function. Cardiomyopathy may be subclinical. Vital capacity may be reduced. These factors change the calculus around induction, ventilation, fluid management, and post-operative recovery.

The 2018 international care considerations include anesthesia and perioperative care as part of standard DMD management. (Birnkrant et al., Lancet Neurology 2018, Part 2)

What is contraindicated

Succinylcholine is contraindicated in DMD. Its use can trigger life-threatening hyperkalemic cardiac arrest from massive potassium release out of damaged muscle. This is an absolute precaution, not a relative one. (OrphanAnesthesia, DMD anaesthesia recommendations)

Volatile inhalational anesthetics (halothane, sevoflurane, isoflurane, desflurane) are best avoided because of the risk of acute rhabdomyolysis, which can lead to acute kidney injury, hyperkalemia, and arrest. Short, low-dose inhalational induction is sometimes accepted in specific situations (such as difficult venous access in a young child), with the team prepared to manage rhabdomyolysis if it occurs.

What is preferred

Total intravenous anesthesia (TIVA) using agents such as propofol and short-acting opioids is the standard general anesthesia approach in DMD. (Parent Project Muscular Dystrophy, Surgery and Anesthesia)

Regional anesthesia, when appropriate to the procedure, is often the safest option. Peripheral nerve blocks avoid airway manipulation and reduce systemic exposure to anesthetic drugs.

Non-depolarizing neuromuscular blockers, when needed, are used cautiously. Patients with DMD are more sensitive, with delayed onset and prolonged recovery.

Before the procedure

Pre-operative assessment in DMD is usually multidisciplinary. Typical components include cardiac evaluation with echocardiogram, baseline pulmonary function testing, review of corticosteroid status and stress-dose planning, review of bone health and recent fractures, and explicit communication of the patient’s DMD status to every clinician involved.

A practical step families can take: confirm in writing, before the procedure, that the surgical and anesthesia team know the diagnosis and the plan. A medical-alert bracelet or wallet card noting DMD and the contraindication to succinylcholine is a reasonable safeguard for emergency situations where the family is not present.

During the procedure

Anesthetic machines should be free of residual volatile agents, with a fresh disposable breathing circuit. Quantitative neuromuscular monitoring is recommended when neuromuscular blockers are used. Continuous ECG monitoring is essential.

The anesthesia team will plan for the increased risk of post-operative respiratory compromise, including possible non-invasive ventilation immediately after extubation for patients who already use it at night or who have significantly reduced vital capacity.

After the procedure

Post-operative recovery in DMD often takes longer than in the general population. Respiratory monitoring, airway clearance with cough assist if needed, pain management without excessive sedation, and early mobilization within the patient’s capacity are common elements.

Corticosteroid stress dosing is considered for patients on long-term steroids, depending on the type and length of the procedure.

What families should ask

Practical questions before any procedure involving anesthesia:

• Does the anesthesia team have experience with neuromuscular disease?
• What is the planned anesthetic, and is succinylcholine excluded?
• What pre-operative cardiac and respiratory tests are needed?
• What is the post-operative monitoring plan?
• Is non-invasive ventilation available immediately after the procedure?
• Who manages corticosteroid stress dosing?

Most pediatric centers with neuromuscular programs answer these as a matter of routine. Asking is the simplest way to confirm.

What is still uncertain

Optimal anesthetic protocols continue to be refined. A 2025 systematic review and meta-analysis catalogued the evidence and noted that high-quality randomized data is limited, with practice largely guided by case series and expert consensus.

The reasonable framing is that anesthesia in DMD is safe when planned by clinicians familiar with the disease, and dangerous when the diagnosis is missed or the precautions are not followed. The decisions belong to the anesthesia and surgical teams working with the rest of the care team.
