Abstract
Summary
Stimulation of the cervical sympathetic trunk, application of local epinephrin, and injection of epinephrin intravenously has been found to produce, not only the classical picture of decreased circulation from narrowing of the vascular bed, but also what looks like blood “sludge” within the vessels.
It is suggested that this may be of interest to those studying small vessel circulation and “sludge” and may have applications in general surgery, general medicine, and psychosomatics.
The author was assisted in these studies by Drs. Robert D. O'Malley, William A. Jarrett, and Octa C. Leigh.
