Abstract

Myoclonic Epilepsy with Ragged Red Fibers (MERRF) represents a complex and multifaceted mitochondrial disorder characterized by myoclonus, seizures, ataxia, and skeletal muscle involvement. The intricacies of anaesthetic management in this unique patient population necessitate a thorough understanding of the underlying pathophysiological mechanisms associated with mitochondrial dysfunction. As MERRF results from mutations in mitochondrial DNA, particularly within the mitochondrial genes associated with oxidative phosphorylation, it profoundly impacts neuromuscular function, thus necessitating tailored anaesthetic protocols. This paper aims to elucidate the anaesthetic challenges inherent in patients with MERRF, focusing on the implications of mitochondrial dysfunction on neuromuscular responses to anaesthetic agents and the subsequent perioperative management considerations.

In patients with MERRF, the propensity for lactic acidosis due to impaired mitochondrial energy metabolism complicates anaesthetic management. The accumulation of lactate during surgical interventions poses significant risks, particularly in the context of volatile anaesthetic agents, which can exacerbate mitochondrial dysfunction and precipitate neuromuscular weakness. The sensitivity to these agents necessitates meticulous dosing and monitoring to mitigate the risk of respiratory depression and other related complications. Furthermore, the role of neuromuscular blockade agents must be carefully considered, as the presence of underlying muscle weakness can lead to unpredictable neuromuscular responses and prolonged recovery times.

In addressing these anaesthetic challenges, this study offers a comprehensive framework for developing personalized anaesthetic protocols that prioritize patient safety and optimize surgical outcomes. Key components of this framework include the careful selection of anaesthetic agents, individualized titration based on the patient’s specific neuromuscular and mitochondrial status, and robust perioperative monitoring to swiftly identify and address potential complications. Emphasis is placed on the integration of multi-disciplinary approaches, wherein collaboration between anaesthesiologists, neurologists, and other healthcare providers is paramount to ensuring comprehensive perioperative care.

In addition to surgical management, this research underscores the importance of seizure control in the perioperative setting. MERRF patients are at an elevated risk for seizure activity due to inherent central nervous system involvement. Consequently, appropriate antiepileptic medications must be administered preoperatively, with careful consideration of potential drug interactions with anaesthetic agents. The aim is to maintain optimal seizure control while minimizing the risk of respiratory depression and hemodynamic instability during the perioperative period.

This study also addresses the importance of patient education and informed consent, emphasizing the need for clear communication regarding the anaesthetic risks associated with MERRF. Patients and their families must be well-informed about the unique challenges posed by the disorder, the potential for complications, and the strategies employed to mitigate these risks during surgical interventions. The inclusion of preoperative counselling as part of the anaesthetic management plan serves to empower patients and enhance their overall experience.
