Sometimes progress is hard to see, when looking at the big picture, because there is very little of it. But sometimes progress is hard to see because the big picture is out of focus. When perioperative deaths ascribed to anaesthesia are in the order of 1 in 20,000 operations and even changes in major morbidity require massive sample sizes to detect, neuroanaesthesia's most emphatic yardstick of progress is too crude to measure advances that have occurred over the most recent decade. ⋯ Of course, this measurement problem plagues anaesthesiology generally, and we need to attend to it in general. Meanwhile, saying where we are relative to the recent past and the near future involves a lot of guesswork. What follows is my guess-work about progress in neurosurgical anaesthesiology.
