Anesthesia and myotonic dystrophy type 2: a case series.

Area of Science:

• Anesthesiology
• Neuromuscular Disorders
• Genetics

Background:

• Myotonic dystrophy type 2 (DM2) is a distinct genetic disorder with overlapping symptoms to myotonic dystrophy type 1 (DM1).
• Anesthetic management guidelines for DM2 patients are currently lacking.
• Understanding patient responses to anesthesia is crucial for safe surgical care.

Purpose of the Study:

• To report the anesthetic management of patients diagnosed with DM2.
• To describe the perioperative responses of DM2 patients to various anesthetic agents and techniques.

Main Methods:

• A retrospective review of medical records was conducted.
• The study identified patients with DM2 who received general, monitored anesthesia care, or regional anesthesia.
• Anesthetic techniques, medications, and postoperative outcomes were analyzed.

Main Results:

• Nineteen DM2 patients underwent 39 general anesthetics, 17 monitored anesthesia care cases, and 2 regional anesthetics.
• Patients demonstrated normal responses to succinylcholine, nondepolarizing neuromuscular blockers, neostigmine, induction agents, and volatile anesthetics.
• No serious postoperative complications directly attributable to DM2 were observed.

Conclusions:

• Commonly used anesthetics were well-tolerated by DM2 patients in this series.
• Normal neuromuscular blocker responses suggest their safe use in DM2.
• These findings support the safe application of standard anesthetic practices for DM2 patients.
