Stimulation at acupoints could be of beneficial effects during the perioperative period. In this study the investigators tend to verify the effect of dual acupoints stimulation on pulmonary complications after abdominal surgery in aged patients.
Postoperative pulmonary complications contributes to the high morbidity of aged patients. The incidence could be as high as 30\~50% in those undergoing abdominal surgery. Stimulation at acupoints have been to alleviate inflammatory response,improve pain management and decrease consumption of opioids, indicating a beneficial effect on pulmonary complications. In this study the investigators tend to verify the effect of dual acupoints stimulation on pulmonary complications after abdominal surgery in aged patients.
