Glyceryl trinitrate as a hypotensive agent in middle-ear surgery.
A total of 47 patients having microsurgery of the middle-ear under general anaesthesia received an infusion of glyceryl trinitrate to produce controlled hypotension. The operating field was evaluated by the surgeon by means of a simple scoring system. Using this technique satisfactory conditions were achieved in all patients without complications.
