BLOOD PRESSURE FOLLOWING ADRENALECTOMY

Abstract
Blood pressure measurements were made before, during, and following adrenalectomy in dogs, by Van Leersum''s (carotid loop) method, which permits observations on non-anesthetized animals. Nearly all of the observations included systolic and diastolic measurements. Observations, made daily, on 1 dog surviving double adrenalectomy about 12 days and another 37 days showed no significant change in blood pressure during the period of good health. A decided and progressive fall of pressure occurred a few days before death, with the onset of the terminal symptoms. This is in accord with earlier studies on rabbits. The dog that survived nearly 37 days was operated for removal of the 2nd adrenal toward the end of the period of rut.
