Sympathectomy - decreased vascular permeability

The influence of the sympathetic nervous system on capillary permeability was studied in cats. The dye penetration from the blood through the synovial membrane was tested by perfusing the two knee joints, one of which was deprived of its sympathetic nerve supply by unilateral lumbosacral sympathectomy.
Further unpublished experiments seem to support the view that increased blood supply is associated with decreased vascular permeability.

Compensatory Sweating developed in all cases

RESULTS: CS developed in all cases. After completion of ETS, mean blood flow and temperature increased respectively. Significant correlations were found between the range of PCS and increases in palmar temperature (p<0.05) and blood flow (p<0.05). CONCLUSION: Intraoperative monitoring of increases in palmar temperature and blood flow may be useful in patients with primary hyperhidrosis, to predict the range of PCS after ETS.
