A prospective study was performed on a group of 100 patients who had spinal anesthesia for transurethral resections of the prostate. On a randomized, double-blind basis one group received crystalline tetracaine and the other received tetracaine solution. Onset, duration of anesthesia, and height of block were compared. There was no observed difference in the two groups.
