Changes in blood and interstitial fluid resulting from surgical operation and ether

Much attention has been given in the past to the study of changes in the blood produced by hemorrhage. Considerably less study has been devoted to changes in body fluid resulting from ether anesthesia, though such findings as elevation of blood sugar, increase in hydrogen ion concen-tration of the blood, and reduction in plasma bi-carbonate, have been well established. The present work presents measurements of changes in quan-tity, as well as concentration, of certain compo-nents of body fluid as found in 16 patients sub-jected to the traumatizing factors of major surgi-cal operations and to ether anesthesia. The time chosen for obtaining data to compare with the preoperative normal values was just at the en
