About
Postoperative cognitive dysfunction(POCD). is a central nervous system complication in cancer patients with a 8.9-46.1% incidence. It is mainly manifested as impaired memory, descending information handling ability and decline or damage of attention, perception, abstract thinking, executive, language, and body movement. However, it is difficult to identify and it can last for months or years or even become a dementia state, which can severely affect patients' postoperative recovery, prolong the hospitalization time, reduce the quality of life, increase the mortality and the consumption of family and social medical resources, and intensifies the national economic and social burden.
Transcutaneous electrical acupoint stimulation (TEAS) is a new type of acupoint stimulation therapy that inputs low-frequency pulse current into human acupoints through electrodes pasted on the skin surface to achieve therapeutic purposes, which combined the preponderances of both acupuncture and transcutaneous electrical nerve stimulation (TENS). TEAS is non-invasive, easy to operate and acceptable to patients. Study showed that TEAS treatment can reduce the consumption of intraoperative anesthetic and improve postoperative nausea and vomiting (PONV) and postoperative recovery.
Also, studies have shown that TEAS treatment may improve the cognitive function of geriatric patients. Most studies have shown that TEAS treatment 10~30 minutes before operation or from entering the operating room to the end of operation can reduce the incidence of POCD in elderly patients. Some studies showed that preoperative combined with postoperative or simple postoperative TEAS treatment can significantly improve patients' postoperative cognitive function. Our previous research showed that perioperative TEAS treatment can reduce the postoperative inflammatory response and increased the postoperative cognitive function score and decrease the incidence of POCD in geriatric patients with gastrointestinal tumor. Moreover, studies showed that long-term electroacupuncture treatment is easy to cause "tolerance effect', leading to the activation of the negative feedback mechanism of the body, and reduction of the number of receptors, and the weakening of the treatment effect. So, what is the best time period for TEAS to improve POCD and reduce the use of resources? Therefore, the objective of this study is to discuss different time of TEAS on POCD in geriatric patients with gastrointestinal tumor.
