ReviewPerioperative respiratory management of pediatric patients with neuromuscular disease.
Patients with neuromuscular disorders undergoing general anesthesia present a special set of respiratory problems for perioperative management. While there are disease-specific concerns, there are many common themes in the respiratory management of patients with neuromuscular disorders. ⋯ Such common perioperative concerns include upper airway obstruction, chest wall restriction, postoperative hypoventilation, inadequate airway clearance, and chronic lower airway disease. Each of these challenges has an effective management approach, and careful planning can help avoid perioperative respiratory complications.

ReviewCore myopathies and malignant hyperthermia susceptibility: a review.
The core myopathies are a subset of myopathies that present in infancy with hypotonia and muscle weakness. They were formerly considered a rare type of congenital myopathy but are now recognized as being more prevalent. Due to their genetic linkage to mutations in the ryanodine receptor gene (RYR1), core myopathies (in particular, central core disease) carry a high risk of malignant hyperthermia susceptibility. ⋯ We also review the level of suspicion a clinician should exhibit with a child who has a possible core myopathy or other congenital myopathy presenting for an anesthetic prior to a definitive genetic analysis. For this review article, we performed literature searches using the key words anesthesiology, core myopathies, pediatric neurology, malignant hyperthermia, genetics, ryanodine receptor, and molecular biology. We also relied on literature accumulated by the two authors, who served as hotline consultants for the Malignant Hyperthermia Hotline of the Malignant Hyperthermia Association of the United States (MHAUS) for the past 12 years.

ReviewPerioperative temperature elevation: not all hyperthermia is malignant hyperthermia.
The objective of this review is to assist the readers, anesthesiologists, intensivists, and emergency physicians in making a more accurate diagnosis of perioperative fever or hyperthermia and subsequently choose the proper course of treatment. ⋯ A literature search was performed which identified many possible common and uncommon sources of fever. Some of these sources are quite relevant to the anesthesiologist. Other sources had potential relevance in obscure cases.
