Effect of Percutaneous Electrical Stimulation at Neiguan,Zusanli and Hegu Points on Recovery of Gastrointestinal Function in Elderly Patients After Surgery for Gastric Cancer
Abstract: Objective: To observe the effect of percutaneous electrical stimulation at Neiguan point (PC6), Zusanli point (ST36) and Hegu point (LI4) on the recovery of gastrointestinal function in elderly patients after surgery for gastric cancer. Methods: A total of 180 elderly patients after surgery for gastric cancer were selected and divided into the conventional group and the electrical stimulation group according to random number table method,with 90 cases in each group. The two groups were given rehabilitation treatment; the electrical stimulation group was given percutaneous electrical stimulation at authentic Neiguan, Zusanli and Hegu points, and the conventional group was given percutaneous electrical stimulation at false Neiguan, Zusanli and Hegu points. The clinical effects and gastrointestinal function recovery, including time of bowel sound returning to normal, first anal farting time and first defecation time, were observed in the two groups. The changes of values of excitatory gastrointestinal hormones, including motilin (MTL), gastrin (GAS) and substance P (SP), and inhibitory gastrointestinal hormones, including vasoactive intestinal peptide (VIP),somatostatin (SS) and cholecystokinin (CCK),were compared between the two groups 2 days before surgery and 3 days after surgery. Results:The total effective rate was 68.89% in the electrical stimulation group and 53.33% in the control group, the difference being significant (P<0.05). The time of bowel sound returning to normal,first anal farting time and first defecation time in the electrical stimulation group were shorter than those in the conventional group (P<0.05). Three days after surgery,the MTL and GAS levels in the two groups were decreased when compared with those before surgery (P<0.05), and SP levels were increased when compared with those before surgery (P< 0.05); the levels of MTL, GAS and SP in the electrical stimulation group were higher than those in the conventional group (P<0.05). Three days after surgery,the levels of VIP and SS in the two groups were decreased when compared with those before surgery (P<0.05), and the levels of CCK were increased when compared with those before surgery (P<0.05);the VIP level in the electrical stimulation group was lower than that in the conventional group (P<0.05),and the SS and CCK levels were higher than those in the conventional group (P<0.05). Conclusion:The percutaneous electrical stimulation at Neiguan,Zusanli and Hegu points can promote the recovery of gastrointestinal function and inhibit gastrointestinal hormone in elderly patients after surgery for gastric cancer.
