Anaesthesia for Paramyotonia Congenita: A Narrative Review

Area of Science:

• Anesthesiology
• Neuromuscular Disorders
• Medical Genetics

Background:

• Paramyotonia congenita (PMC) is a rare, non-progressive neuromuscular disorder.
• Characterized by muscle stiffness and delayed relaxation after contraction or stimulation.
• Rarity poses anesthetic management challenges due to infrequent clinical encounters.

Purpose of the Study:

• To synthesize literature on anesthetic management for patients with Paramyotonia congenita.
• To provide anesthesiologists with a focused understanding of PMC's perioperative considerations.
• To highlight choice of anesthetic agents and reported outcomes for safe practice.

Main Methods:

• Narrative review of existing literature.
• Synthesis of studies focusing on anesthetic management in PMC patients.
• Identification of recurring management principles and reported outcomes.

Main Results:

• Anesthetic techniques for PMC patients vary.
• Key management principles include avoiding stiffness triggers and maintaining careful temperature control.
• Readiness to manage potential complications is crucial.

Conclusions:

• While no single optimal anesthetic approach exists for PMC.
• Current literature suggests safe anesthesia is achievable with planning and vigilance.
• Perioperative care requires specific attention to PMC's unique characteristics.
