The muscular dystrophies are inherited myogenic disorders characterized by progressive muscle wasting and weakness of variable distribution and severity. They can be subdivided into several groups, including congenital forms, in accordance with the distribution of predominant muscle weakness: Duchenne/Becker; limb-girdle; Fukuyama type congenital muscular dystrophy; Emery-Dreifus; facioscapulohumeral; oculopharyngeal; myotonic dystrophy, et al. ⋯ Depolarizing neuromuscular blocking drugs that cause rhabdomyolysis are contraindicated in these patients. Recommendations are proposed for the safe anesthetic management of these patients.

Several surgical treatments can be employed for the patients with neurological disorders, such as multiple sclerosis, Guillain-Barré syndrome, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer disease and spinal cord injury. It is possible that anesthesia related complications are induced in these neurologically complicated patients in the perioperative period. Respiratory dysfunction and autonomic nervous system dysfunction are most common in this population. ⋯ Some therapeutic agents prescribed for neurological symptoms have drug interaction with anesthetic agents. Patients with motor neuron disease should be considered to be vulnerable to hyperkalemia in response to a depolarizing muscle relaxant. Although perioperative treatment guideline for most neurologic disorders has not been reported to lessen perioperative morbidity, knowledge of the clinical features and the interaction of common anesthetics with the drug therapy is important in planning intraoperative and postoperative management.

Transversus abdominis plane block (TAP block) is useful for lower abdominal operations. Recently, ultrasound guided nerve block has been performed with ultrasound scanning. ⋯ We concluded that TAP block was effective in pediatric patients receiving bone graft to the alveolar cleft.

Two principles should be kept in mind when performing preoperative evaluation of the elderly patient. First, we should suspect the disease processes commonly associated with aging. Second, we should assess the degree of functional reserve of specific, pertinent organ systems. ⋯ Especially, it is important to examine the cardiovascular and respiratory functions in the elderly patient. Further, this also includes assessment of consumed drugs, physiological function, cognitive function, competency, availability of social support, and sign of depression. Surgical risk and outcome in the elderly patient depend primarily on four factors: age, the patient's physiological status and coexisting disease, whether the surgery is elective or urgent, and the type of procedures.

Tracheal extubation and emergence procedures induce abrupt changes in hemodynamics and humoral responses. The purpose of this study was to examine the effects of different doses of landiolol on hemodynamics during emergence from anesthesia. ⋯ Landiolol could prevent the increase in heart rate but not blood pressure during emergence from anesthesia. Effects on the changes in heart rate between 0.125 and 0.06 landiolol groups were not significantly different.
