| Research Abstract |
(1) Stress during Surgery and Immunological Reaction
Immuno-suppressive changes occured on the patients anesthetized with inhalation anesthesia itself or NLA during major surgery. General anesthesia with epidural block or splanchnic nerve block inhibit this changes.
(2) Stress during Surgery and Plasma Cortisol Concentration
General anesthesia with epidural block never depressed the increase of plasma cortisol concentration during upper abdominal surgery. The planchnic nerve block depressed the increase of plasma cortisol concentration significantly.
(3) Sympathetic Nerve System
Some kinds of stress including surgical stress and pain stress influence Sympathetic Nerve System.
Quantitative analysis of pain can be evaluated by monitoring changes in the blood flow and sweating. We utilized this method and evaluated the sympathetic nerve system responce to noxious stimulation.
(4) Reflex Sympathetic Dystrophy (RSD)
Our data suggest that the autonomic disturbance in incurable RSD are due to supersensitivity to sympathetic neurotransmitters rather than due to sympathetic overactivity.
(5) Laser
We evaluated the effect of low-reactive level laser by irradiateing to stellate ganglion.
(6) Cytokine
To examine the role of spleen under the surgical stress, we investigated the changes of plasma cytokine levels in the splenic vein blood and the arterial blood. The data suggested that the spleen produces intensively IL-6 under surgical stress.
