Feedback during patient-controlled analgesia using a speech synthesizer.
Patients who use on-demand analgesia prefer voice feedback rather than buzzer tones to indicate operation of the apparatus. Twenty-four patients had experience of a patient-controlled analgesia apparatus which incorporated a sophisticated feedback of buzzer tones and a speech synthesizer. Of those who expressed a preference, fifteen preferred the speech synthesizer and only one preferred the buzzer tones. The speech synthesizer is a reliable, inexpensive and simple method of supplying feedback to patients when such apparatus is used.
