We describe a practical video-assisted thoracoscopic surgery (VATS) technique for the en bloc resection of the thymoma, thymus, and bilateral mediastinum lipid based on mediastinal pleura guidance. By taking advantage of single-lumen endotracheal tube (SLET) anesthesia and artificial pneumothorax, we acquired excellent exposure of the anterior mediastinum operative field. In addition, our limited data showed that this surgical approach might have a potential tendency on reducing the blood loss and the operative times...

Myasthenia gravis (MG) is an autoimmune disease characterized by the production of antibodies against the acetylcholine receptor, muscle-specific kinase (MuSK), or other proteins at the neuromuscular junction. MG with antibodies against MuSK (MuSK-MG) has been described recently. Here, we report the first case of anesthetic management of a patient with MuSK-MG undergoing an open cholecystectomy. In our case, propofol and remifentanil-based anesthesia were used for successful management without using muscle relaxants...

INTRODUCTION: Sugammadex is the first clinical representative of a class of drugs called steroidal muscle relaxant encapsulators. Due to its 1:1 binding of rocuronium or vecuronium, sugammadex can reverse any depth of neuromuscular block and has therefore revolutionized the way anesthetists think about drug reversal. AREAS COVERED: This review gives an overview of the clinical pharmacology and efficacy of sugammadex in healthy patients as well as in patients with pre-existing diseases...

Myasthenia gravis causes weakness and fatigue of the skeletal muscles, including respiratory muscles. When immobile surgical fields are needed, neuromuscular blocking agents (NMBAs) are often administered to block muscle activity, leading to an immobile surgical field and respiratory arrest. Acetylcholinesterase inhibitors are administered to reverse the muscle block, promoting spontaneous respiration for patient recovery. If immobile surgical fields are required in myasthenic patient operations, NMBAs should be administered...

A 58-year-old man developed cough, sputum, and low-grade fever during immunosuppressive treatment with corticosteroids and cyclosporine for myasthenia gravis with recurrent thymoma. Since chest CT revealed diffuse nodular opacities in both lung fields, he was referred to our department. Mycobacterium abscessus was repeatedly cultured from his sputum, and he was diagnosed with pulmonary M. abscessus infection. Although both chest radiological findings and clinical symptoms were mild, he required treatment with immunosuppressive agents and systemic anesthesia for resection of the recurrent thymoma...

UNLABELLED: Adequate preoperative evaluation and preparation for surgery are required to prevent prolonged mechanical ventilation after thymectomy, and facilitate the recovery of patients with myasthenia gravis (MG). The objective of this study was to identify the preoperative risk factors for extubation failure after thymectomy in patients with MG. METHODS: A retrospective study was conducted on 61 patients with MG who underwent extended thymectomy. Several factors were evaluated including patients' demographic data, preoperative medical therapies, medical history, and comorbidities...

Myasthenia gravis, a disorder of neuromuscular transmission, presents a unique challenge to the perioperative anesthetic management of morbidly obese patients. This report describes the case of a 27-year-old morbidly obese woman with a past medical history significant for myasthenia gravis and fatty liver disease undergoing bariatric surgery. Anesthesia was induced with intravenous agents and maintained with an inhalational and balanced intravenous technique. The nondepolarizing neuromuscular blocker Cisatracurium was chosen so that no reversal agents were given...

Nowadays, even hazardous cardiac surgery can be performed on patients with autoimmune diseases like myasthenia gravis. It requires a sensitive perioperative anesthetic approach especially in relation to nondepolarizing muscle relaxant administration. Myasthenic patients produce antibodies against the end-plate acetylcholine receptors causing muscle weakness and sensitivity to nondepolarizing muscle relaxants that could lead to respiratory failure. Perioperative nurse care is critical for uncomplicated course of treatment; therefore, apprehension of surgical procedure should be helpful on an everyday basis...

Although maintaining anesthesia for myasthenia gravis (MG) with minimal muscle relaxants (MR) is common, the success rate of anesthetic management for MG without MR is not clear. We therefore retrospectively examined the success rate of anesthetic management for MG without MR among 66 consecutive cases of thymectomy for MG performed at our hospital between January 2004 and April 2010, before approval of using sugammadex. A total of 60 patients (90.9 %) were treated without MR (N group). Among the 60 cases, 17 (28...

Myasthenia gravis (MG) is an autoimmune disease affecting neuromuscular junction, which is characterized by fluctuating muscle weakness and abnormal fatigability. The use of muscle relaxants is major concern in anesthetic management for patients with MG. Muscle relaxant is a practical tool to assure immobilization during surgery under general anesthesia Anesthetic management without muscle relaxants for patients with MG is challenging, because it is difficult to assure immobilization. However, pharmacological effects of muscle relaxants can be prolonged in patients with MG, resulting in the increased incidence of postoperative respiratory support...

Terminal Schwann cells (TSCs) are key components of the mammalian neuromuscular junction (NMJ). How the TSCs sense the synaptic activity in physiological conditions remains unclear. We have taken advantage of the distinct localization of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) at the NMJ to bring out the function of different ACh receptors (AChRs). AChE is clustered by the collagen Q in the synaptic cleft and prevents the repetitive activation of muscle nicotinic AChRs. We found that BChE is anchored at the TSC by a proline-rich membrane anchor, the small transmembrane protein anchor of brain AChE...

Women with neurologic conditions present a challenge during pregnancy and in the peripartum period. Given the low prevalence of these diseases during pregnancy, most management decisions are guided by retrospective reviews and case reports. This article reviews current literature for some of the more common or complex neurologic conditions affecting pregnancy with special consideration for anesthetic management. In particular, epilepsy; multiple sclerosis; primary intracranial hypertension; secondary intracranial hypertension-Arnold-Chiari malformations and intracranial neoplasms; spinal cord injury; neuromuscular junction disorders-myasthenia gravis; and hereditary neuromuscular disorders-myotonic dystrophy and spinal muscular atrophy will be discussed...

Literature on anesthetic management of juvenile myasthenia gravis (JMG) for thymectomy is limited. Recently, use of inhalational agents and total intravenous anesthesia with propofol and remifentanyl has been reported. All these techniques individually or in combination have been tried to avoid the use of muscle relaxant. We report successful use of sevoflurane as sole anesthetic agent for intubation and in combination with thoracic epidural anesthesia for intraoperative anesthetic management in a 5-year-old child with JMG...

Myasthenia gravis is an autoimmune neuromuscular disorder that causes the destruction and overall decrease in functional acetylcholine receptors at the neuromuscular junction. The resultant respiratory and cardiovascular implications are a primary cause of mortality; therefore, a complete and comprehensive understanding of this disorder is vital for the anesthesia provider. The case presented demonstrates the anesthetic challenges involved, with a focus on the overall approach, pharmacologic considerations, physiological changes, and an emphasis on preoperative optimization...

Sugammadex is the first clinical representative of a new class of drugs called selective relaxant binding agents. It has revolutionized the way anesthesiologists think about drug reversal. Sugammadex selectively binds rocuronium or vecuronium, thereby reversing their neuromuscular blocking action. Due to its 1:1 binding of rocuronium or vecuronium, it is able to reverse any depth of neuromuscular block. So far, it has been approved for use in adult patients and for pediatric patients over 2 years. Since its approval in Europe, Japan, and Australia, further insight on its use in special patient populations and specific diseases have become available...

PURPOSE: We report on two patients with ocular myasthenia gravis who received rocuronium, followed later by sugammadex to reverse neuromuscular blockade. Recovery was monitored simultaneously at the adductor pollicis muscle (APM) and the corrugator supercilii muscle (CSM). CLINICAL FEATURES: Two patients with ocular myasthenia gravis (case 1: 74 yr-old female, 54 kg; case 2: 71 yr-old male, 72 kg) were scheduled for surgery under general anesthesia. Neuromuscular blockade was induced with rocuronium 0...
