Fig. 4. Effects of surgery, intestinal manipulation (IM), and electroacupuncture (EA) on intestinal slow waves. (A) Dominant frequency of slow waves in the 3 groups of rats during the 3 postoperative hours; it was reduced by IM but this reduction was normalized by EA during the third postoperative hour (*P < 0.05). (B) Dominant power of slow waves during the 3 postoperative hours in each group. A postoperative increase in dominant frequency was noted in all 3 groups (*P < 0.05). (C, D) Dominant power of intestinal slow waves in 3 groups of rats during different postoperative hours. No consistent effects were noted by surgery, IM, or EA. (E) %S-normal: the percentage of normal slow wave component distribution in the power spectrum in the 3 groups of rats during different postoperative hours. It was not altered by IM or EA. (F) %S-normal: the percentage of normal slow wave component distribution during the 3 postoperative hour in different groups of animals. A significant postoperative recovery was noted in the control and EA group but not sham-EA group, suggesting an IM-induced delay in postoperative recovery. *P < 0.05.
