Effects of Some Anesthetic Drugs on the Ventricular Fluid Pressure and on the Systemic Blood Pressure Both Arterial and Venous

The effects of general anesthetic drugs on intracranial pressure has been a frequent subject of research for some years, beginning with the pilot research by Woringer et al. [1, 2]. However, basic knowledge of their mechanism has only recently been obtained. Especially important are the data of McDowall and coworkers [3, 4, 5] on the direct vasodilatatory action of the volatile anesthetics on the cerebral circulation.
