The Use of Tetraethylammonium Chloride as a Vasodilator in Peripheral Vascular Disease; Its Effect on Sympathectomized Extremities
The thermometric and plethysmographic response to Etamon administration was studied in 13 patients with peripheral vascular disease, comparing it with that of procaine injection into the sympathetic ganglia. The administration of Etamon caused an average temperature rise of 7 degrees F. and a pulse volume increase of 1.3 cu. mm. per 5 cc. of part. Procaine block resulted in a temperature rise of 13.5 degrees F. and a pulse volume increase of 5.5 cu. mm. Etamon was given to 11 vascular patients after sympathectomy and caused an average temperature rise of 0.5 degrees F. in the sympathectomized extremities, while the pulse volume actually decreased by an average of 0.7 cu. mm. per 5 cc. of part.
