Abstract

Massive quantities of cerebrospinal fluid obtained at the time of the insufflation of air into the lumbar subarachnoid space may or may not show variations in the commonly analyzed elements when they are subjected to fractional examination. The variations noted are limited almost entirely to the cell content. The results of analysis for the other fluid constituents were relatively uniform. Because of the constant, rapidly appearing headache, stiff neck and fairly frequent subsequent nausea, vomiting and fever in persons who have submitted to encephalography, air is considered to be irritating to the meninges. Herrmann¹tended to substantiate this idea by observing a marked pleocytosis (chiefly polymorphonuclear leukocytes) and a high albumin content in cerebrospinal fluid obtained as early as fourteen hours after spinal inflations were performed on three psychotic patients. Friedman, Snow and Kasanin²reported a similar cellular increase in the fluid from three of forty-seven patients who
