Abstract

The three traditional concentrations in which European insulins are prepared for therapeutic purposes often hinder understanding, sometimes cause accidents and occasionally disaster. When syringes other than the BS1619 are used the risks are increased. Insulin preparations containing 100 units/ml used with syringes graduated to contain one unit in one division (e.g. a tuberculin syringe) have been tested as part of a trial organized by the British Diabetic Association. Parents preferred the new system, which facilitated learning and reduced the possibility of error.
