Comparison Of Analgesic And Gastrointestinal Function Recovery Effect Of Different Teas Stimulation Time During Perioperative Period On Patients Received Laparoscopic Radical Gastrectomy

Objective To compare the effects of different transcutaneous electrical acupoint stimulation(TEAS)on the analgesia and gastrointestinal function recovery after laparoscopic radical gastrectomy for gastric cancer.Methods A total of 150 gastric cancer patients undergoing laparoscopic radical gastrectomy were randomly assigned into the long duration TEAS(L-TEAS)group,the short duration TEAS(S-TEAS)group,or the placebo-control(C-TEAS)group.All the 3 groups were routinely induced.For the S-TEAS group TEAS was maintained from anesthetic induction to the end of the operation.For the S-TEAS group TEAS was maintained from 0.5 h before anesthetic induction to 0.5 h after the operation,and TEAS was performed for 0.5 h per 8 h within 2 d after the operation.Stimulation sites included bilateral Zusanli(ST 36)and Neiguan(PC 6).Postoperatively,the patients received patientcontrolled intravenous analgesia(PCIA).The consumption of analgesics as well as the scores of the visual analogue scale(VAS)and Ramsay Sedation Scale(RSS)at 4 h(T1),8 h(T2),16 h(T3),24 h(T4)and 36 h(T5)were observed and recorded after the operation in the 2 groups.The duration of first bowel sounds,flatus and defecation were recorded after the operation.The incidence of postoperative nausea and vomiting(PONV)as well as patient satisfaction was recorded.Results The consumption of analgesics at 4 h and 8 h after operation in the short TEAS group and the long TEAS group was significantly lower than that in the control group(P<0.05).The consumption of analgesics at 4 h after operation in the long TEAS group was significantly lower than that in the short TEAS group(P<0.05).VAS at 4 h 8 h and 24 h after operation in the long TEAS group reduced evidently as compared with the control group(P<0.05).The duration of first bowel sounds in the short TEAS group and the long TEAS group was shortened apparently compared with the control group(P<0.05).Compared with other 2 groups,the duration of defecation in the long TEAS group was significantly shorter(P<0.05).The duration of first anus exhaust in the L-TEAS group was shortened apparently compared with the C-TEAS group(P<0.05).The incidence of PONV in the LTEAS group was significantly lower than that in the control group(P<0.05).The rate of satisfaction in the L-TEAS group and the C-TEAS group was higher than for that in the CTEAS group,and for very satisfied,the L-TEAS group was higher than that in the S-TEAS group(P<0.05).No significant difference was observed with respect to RSS among the three groups(P>0.05).Conclusion TEAS combined with general anesthesia can reduce the consumption of analgesics,and shorten the duration of first bowel sounds after radical gastrectomy for gastric cancer.Compared with intraoperative TEAS,perioperative TEAS can more effectively reduce early postoperative pain,reduce the incidence of PONV,shorten the duration of first defecation after the operation,more effectively promote the recovery of gastrointestinal function and improving the patient satisfaction rate.Figure 6,Table 7,Reference 141...
