    Reprinted Jrom The Lancet, September 15, 1900. A NOTE ON THROMBOSIS IN THE VEINS OF THE PELVIS AND LOWER EXTREMITIES AFTER OPERATIONS. By K. G. LENNANDER, Hon. F.R.C S. Eng., PROFESSOR OF SURGERY IN THE UNIVERSITY OF UPSALA. (Translated from, the Swedish by I. Walker Hall, M.B. Viet., Senior Demonstrator of Physiology, Owens College, Manchester.) Some remarks of mine upon this subject appeared in the Upsala Lakare Forenivgs Forhandlingar of January, 1899, and in the Centralblatt fur Chirurgie, 1899. The results obtained during 18 months following July, 1897, led me to suggest that after every herniotomy or abdominal opera- tion the patient’s bed should be raised at its lower end some 10 to 50 centimetres (from 4 to 19 inches) in order mechanically to assist the venous blood flowing from the lower extremities towards the heart, and so preventing thrombosis. This could be best accomplished by placing square pieces of wood under the feet. By such means the change in the position of the body caused the blood to flow along a plane inclined towards the inferior vena cava, and if the shoulders were not raised equally so towards the right auricle. Such a raising of the bed must therefore also make the flow of the blood from the veins in the true pelvis and from the exterior genitals more rapid than in the horizontal position. When the blood-stream has reached the inferior vena cava it will certainly be impelled /towards the heart by the negative pressure in the thorax at every inspiration. Since January, 1899, this procedure has been adopted up to date in my practice and no case of thrombosis in the pelvic or lower extremity veins has
