During general anesthesia for some specific surgical cases which need to lower blood pressure

hypotension induced lower blood-perfusion of tissues and the subsequent blood pressure-raising and reperfusion may induce an imbalance between tissue perfusion and oxygen metabolism

probably leading to different degrees of injury of the brain

heart

liver

gastrointestinal tract

etc..Nowadays

simple acupuncture anesthesia has been become into compound anesthesia of acupuncture and drugs

and transcutaneous electrical acupoint stimulation(TEAS)has been already used as one principal measure for acupuncture anesthesia.It has been demonstrated that acupuncture stimulation has a protective effect on the important organs as brain

heart

liver

kidney

etc.

and there exists a central dependability between acupuncture analgesia and blood pressure regulation.In addition

it has been found that during controlled lowering of blood pressure by TEAS in combination with isoflurane general anesthesia

both oxygen metabolism in tissues and performance of the circulation system are rather stable.Along with the increasing of cranial operation and major-arthroplasty

TEAS which possesses important organ protective effect during controlled-blood pressure lowering under general anesthesia has a good applicable prospect.
