| Abstract |
The main effect of upper thoracic sympathectomy is sudomotor. To abolish sweating of the palms, T(2) ganglionectomy (often with the addition of T(3)) was invariably performed. To prevent axillary sweating, additional T(4) 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. T(2)-T(3) 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. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 December 2008.
All research outputs
#7,452,489
of 22,783,848 outputs
Outputs from Clinical Autonomic Research
#297
of 775 outputs
Outputs of similar age
#33,289
of 133,039 outputs
Outputs of similar age from Clinical Autonomic Research
#2
of 5 outputs
Altmetric has tracked 22,783,848 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 775 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.9. This one has gotten more attention than average, scoring higher than 50% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 133,039 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
