There are many cases of peripheral nerve injury by patient position during perioperative period. It is thought to occur by compression or traction and ischemia of nerves. We had an experience that injury of common peroneal nerve below fibular head occurred by lithotomy positon during operation for urethral stricture under spinal anesthesia. Because the nerve injury can be reduced by some caution, it is important to be well-informed about and predict the risk of peripheral neuropathy during lithotomy position.

This is the case report of a 58-year-old man who developed acute severe hypoglycemia after a spinal block. He had a history of injecting insulin combined with 50% dextrose for hyperkalemia control. After the spinal block, he presented with hypo-glycemic symptoms and went into convulsions. Following injection of midazolam and 10 ml of 50% dextrose, his mental state returned to alert. We recommend careful monitoring of blood sugar level of chronic kidney disease patients who under-go neuraxial block.
