Abstract
As part of the Journal’s 60 anniversary Diamond Jubilee Celebration, a number of seminal articles from the Journal archives are highlighted in the Journal’s 61 printed volume and online at: www.springer.com/12630. The following article was selected on the basis of its novelty at the time of publication, its scientific merit, and its overall importance to clinical practice: Keeri-Szanto M. Apparatus for demand analgesia. Can Anaesth Soc J 1971 18: 581-2. In this article Dr. John Penning presents expert commentary on a prototype patient-controlled analgesia apparatus described by Dr. Keeri-Szanto in the legacy Canadian Anaesthetists’ Society Journal, published in 1971. The prototype utilized a compact, relatively inexpensive syringe driven motor mechanism a system that could be employed with safety, for the first time, on surgical wards.
