Results The recovery time of bowel sound was 8-112 h (M=28 h) in the treated group and 16-24 h (M=46 h) in the control group, with a significant difference P=(0.0001. The time of anal exsufflation in the treated group was 2-116 h (M=56 h), and 24-147 h (M=82 h) in the control group, with a significant difference (P=0.0001). The electroenterogram revealed that control activity, continuous response activity and contractive electrical complex were significantly stronger in the treated group than in the control group.
