ABSTRACT
Using three psychomotor tasks administered three times each at 2-week intervals, we studied the performances of 18 control subjects and 18 subjects who were routinely and daily exposed to trace concentrations of anesthetic gases in the course of their clinical practice. No significant differences attributable to exposure to trace concentrations of anesthetics were detected. It is concluded that laboratory studies may overestimate the degree of alteration of psychomotor skills associated with exposure to trace concentrations of inhalation anesthetics.

An acute episode of pulmonary edema may occur in association with head injury. This is due to the elevation of systemic blood pressure, to maintain cerebral circulation in the presence of increasing intracranial pressure (ICP). In these instances, the pulmonary edema arises as a pathophysiologic, neurohemodynamic response to the intracranial disease. This response has been produced experimentally, and 2 case reports described this problem clinically. If such patients with increased ICP could be treated immediately with antihypertensive drugs, pulmonary edema might be prevented and the high mortality rate decreased.
