ReviewAnesthesia management for electroconvulsive therapy: hemodynamic and respiratory management.
Recent guidelines have stated that anesthesia for electroconvulsive therapy (ECT) should be administered by a specially trained anesthesiologist, and that anesthesiologists have overall responsibility, not only for anesthesia itself, but also for cardiopulmonary management and emergency care. Accordingly, anesthesiologists who administer anesthesia for ECT should have sufficient knowledge regarding the physiologically and pharmacologically unique effects of ECT. Electrical current during ECT stimulates the autonomic nervous system and provokes unique hemodynamic changes in systemic and cerebral circulation. ⋯ Reports of serious complications of this therapy are not frequent; however, patients with ischemic heart disease or cerebrovascular problems must be managed with special care to prevent myocardial infarction or neurological disorders. Safe physical management by anesthesiologists greatly contributes to the establishment of ECT under muscle relaxation. To maintain social confidence and to refine the therapy, anesthesiologists should play an essential role both in clinical activities and in laboratory research.

ReviewDrugs to facilitate recovery of neuromuscular blockade and muscle strength.
Several drugs that quicken recovery from neuromuscular blockade caused by vecuronium in anesthetized patients are reviewed. Ulinastatin, a protease inhibitor, is thought to promote the release of acetylcholine at the neuromuscular junction and increases hepatic blood flow and urine volume. For this reason, ulinastatin quickens recovery from neuromuscular blockade in anesthetized patients receiving vecuronium. ⋯ Therefore, recovery from neuromuscular blockade is hastened. Nicorandil enhances membrane K+ conductance in skeletal muscle and increases contraction of the skeletal muscle. Thus, nicorandil quickens recovery from neuromuscular blockade.
