This is probably the most extensive clinical and laboratory treatise dealing with all the medical phases that come up in the control of a diabetic state before, after and during surgery. The underlying theme of the treatment is saline solution from 10 to 20 Gm., insulin and dextrose intravenously. The point in which this differs from the American publications is the stress which the authors lay on the administration of salt in hypertonic solutions. Their experiments as well as their clinical data sound convincing. The authors cover the world literature and the book is well worth while for those who have to deal with surgery and diabetes. The author has paid close attention to detail, which is the criterion of his successful therapy.
