The Pathophysiology of Cervical and Upper Thoracic Sympathetic Surgery

Clin Auton Res. 2003 Dec;13 Suppl 1:I40-4.

Though this paper was published in 2003, most of the 55 cited studies are from many years ago. This paper is devastating in two respects. First, it documents in no uncertain terms the horror suffered by ETS victims. And secondly, it proves that the ETS surgeons have known all along what they were doing.

Here are a few excerpts from the full article, followed by the abstract and references:

"Upper dorsal sympathectomy [ETS] significantly decreases pulse rates at rest and after effort."

"[ETS] blunts the blood pressure response to exercise"

"In some cases, severe bradycardia requiring permanent pacing [a pacemaker] may result from bilateral T2sympathectomy"

"Sympathectomy produces a vasodilatatory cutaneous effect"

"The [blood] circulation in the muscles . . . may even be reduced."

"[ETS] significantly decreases pulse rate and systolic blood pressure, reduces myocardial oxygen demand, increases left ventricular ejection fraction and prolongs Q-T interval."

"A certain loss of lung volume and decrease of pulmonary diffusion capacity for CO result from sympathectomy [ETS]."

"Studies . . . in normal . . . humans have shown that sympathetic blockade invariably produces intense skin vasodilation resulting in redistribution of total limb blood flow with reduction of blood flow to muscles."

"[ETS] results in elevation of skin temperature . . ."

The abstrcact reads as follows:

Abstract.   The main effect of upper thoracic sympathectomy is sudomotor. To abolish sweating of the palms, T2 ganglionectomy (often with the addition of T3) was invariably performed. To prevent axillary sweating, additional T4 ablation was recommended. Sympathectomy produces a vasodilatatory cutaneous effect. The circulation in the muscles, however, is unaltered or may even be reduced. It also appears that improved skin blood flow is on the thermoregulatory, not nutritive level. It seems that chronic surgical sympathectomy does not cause major changes in the vascular function of the forearm. Although the exact pathophysiological mechanism of blushing is still obscure, bilateral upper dorsal sympathectomy alleviates this phenomenon. T2-T3 ganglionectomy significantly decreases pulse rate and systolic blood pressure, reduces myocardial oxygen demand, increases left ventricular ejection fraction and prolongs Q-T interval. A certain loss of lung volume and decrease of pulmonary diffusion capacity for CO result from sympathectomy. Histomorphological muscle changes and neuro-histochemical and biochemical effects have also been observed.
