A Review on the Anesthetic Management of Patients with Neuromuscular Diseases.

CONTEXT: Neuromuscular diseases (NMDs) are regarded as a clinically and genetically heterogeneous group of diseases characterized by weakening muscle strength and dystrophic changes in the muscle. Due to the nature of these diseases, it can be challenging for anesthesiologists to provide appropriate pain medications, symptom management, and other necessary techniques that are implemented to anesthetize the patient properly.

EVIDENCE ACQUISITION: This study was based on the available literature and the authors' experience. The current study aimed to review the available anesthesia for patients suffering from NMDs. The search process resulted in the detection of relevant articles using valid keywords on electronic databases, including Embase, PubMed, Scopus, Web of Science, and Cochrane Library. Subsequently, 19 articles published between 2009 to 2022 were identified as eligible for this review.

RESULTS

When anesthetizing a patient with NMD, special attention should be paid to preoperative evaluation, medical-history taking, risk of difficult intubation or cardiac incidents, respiratory insufficiency, and frequent pulmonary infections. It is also necessary to keep in mind that these patients are at risk of prolonged paralysis, hyperkalemia, rigidity, malignant hyperthermia, cardiac arrest, rhabdomyolysis, or even death.

CONCLUSIONS

Problems of anesthesia in patients with NMDs arise from the nature of the condition itself and the interaction of anesthetics and muscle relaxants with anticholinesterase drugs used in therapy. Each patient's individual risk should be assessed before anesthesia. Therefore, it is important (and even necessary before major surgery) to perform a thorough preoperative examination to not only determine perioperative risk but also to ensure optimal perioperative follow-up.
