Lower deep venous thrombosis (DVT) is one of the major complications of patients with tumors or patients undergoing major surgery. Electrical acupoint stimulation, an established technique of traditional Chinese medicine, can be well combined with Western medicine to reduce the incidence of postoperative DVT, especially in elderly patients1. Purpose: The purpose of the study was to determine the effect of electrical acupoint stimulation on blood viscosity of patients undergoing colorectal tumor surgery. Subjects and Methods: Thirty patients who had malignant colorectal tumor stage A ,B,C and D undergoing elective surgery for that tumor selected randomly and divided into two equal groups. Group 1 include 15 patients that received standard traditional physical therapy postoperative care from the first day after surgery for 1 week. Group 2 include 15 patients who received the same treatment as group1 plus electrical acupoint stimulation from the first day after surgery for 1 week. Blood viscosity in both groups were assessed using platelet count, prothrombine concentration and color duplex study of the blood flow velocity in the veins of lower limbs. Results: The results of this study showed significant decrease in the blood viscosity of lower limb veins in the group 2 that used electrical acupoint stimulation over group 1(P value < 0.001) . Conclusion: It was concluded that electrical acupoint stimulation is an effective method to increase blood viscosity and hence decrease the incidence of DVT after colorectal tumor surgery.
