Exacerbation of myasthenia gravis after tourniquet release

J Clin Anesth. 2007 Nov;19(7):543-5. doi: 10.1016/j.jclinane.2007.01.011.


By avoiding use of neuromuscular blocking agents, regional anesthesia techniques may allow safer care of patients with myasthenia gravis. We describe a patient who had myasthenic crisis after foot surgery during spinal anesthesia. Lactate released on deflation of bilateral tourniquets constituted the most likely cause of the exacerbation.
