Influence of auricular point sticking on incidence of nausea and vomiting and analgesia effect after gynecological laparoscopy / 中国针灸

<p><b>OBJECTIVE</b>To observe the influence of auricular point sticking on incidence of nausea and vomiting and analgesia effect after gynecological laparoscopy, and provide evidence for clinical application of auricular point sticking.</p><p><b>METHODS</b>One hundred and twenty cases of selective gynecological laparoscopy under general anesthesia were randomly divided into an auricular point sticking group and a placebo group, 60 cases in each group. In the auricular point sticking group, the auricular point sticking with vaccaria seeds was applied at Shenmen (TF 4), Wei (CO 4) and Jiaogan (AH 6a) before the operation and 1, 5, 9, 23 h after the operation, which were pressed 5 min each point each time. The two ears were proceeded at the same time. In the placebo group, the same point selection, sticking paste was used as the auricular point sticking group, but no sticking or pressing with vaccaria seeds was adopted. The incidence of nausea and vomiting, the usage rate of tropisetron and morphine within 24 hours of the operation, as well as the score of visual analogue scale (VAS) and other adverse reactions at 2, 6, 10, 24 h after the operation were observed respectively.</p><p><b>RESULTS</b>Compared with the placebo group, the incidence of nausea and vomiting [31.7% (19/60), 16.7% (10/60) vs 58.3% (35/60), 35.0% (21/60)], the usage rate of tropisetron [21.7% (13/60) vs 48.3% (29/60)] and morphine [18.3% (11/60) vs 38.3% (23/60)], the VAS scores at all different time points in the auricular point sticking group were all decreased (all P < 0.05), and no adverse reaction was observed.</p><p><b>CONCLUSION</b>The auricular point sticking could significantly decrease the incidence of nausea and vomiting in patients of gynecological laparoscopy and has positive analgesic effect.</p>

Efficacy and safety of patient-controlled sedation with transcutaneous electrical stimulation of auricular Shenmen (TF4) in cesarean section / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the efficacy and safety of patient-controlled sedation with transcutaneous electrical stimulation of auricular Shenmen (TF4) in cesarean section.</p><p><b>METHODS</b>A randomized controlled clinical trail was conducted on 180 singleton primiparas (SAS > 30) undergoing selective cesarean section. They were randomly assigned to three groups, i. e., the patient-controlled sedation with transcutaneous electrical stimulation of auricular Shenmen (TF4) group (Group A, 60 cases), the patient-controlled sedation with transcutaneous electrical stimulation of auricular eye point group (Group B, 60 cases), and the control group (Group C, 60 cases). Patients in Group A received patient-controlled sedation with transcutaneous electrical stimulation of auricular Shenmen (TF4) in the operating room. The strength was controlled by patients themselves. The stimulation lasted for 30 min before the epidural puncture till ending the surgery. Patients in Group B received stimulation of auricular eye point. Patients in Group C received pressurization with the same connected line as Group A, but without electric stimulation. The following indices were observed: (1) the bispectral index (BIS), heart rate (HR), mean arterial pressure (MAP), Ramsay sedation score when the women entered the operating room (T0), 30 min after stimulation (T1), at the time after removing the fetus (T2), and by the end of surgery (T3); (2) the concentrations of plasma angiotensin II (AngII) and cortisone (Cor) at the aforesaid time points; (3) the use rates of oxytocin, atropine, and ephedrine; the hemorrhage amount, and the neonatal Apgar score.</p><p><b>RESULTS</b>Compared with Group A, the BIS, the plasma concentrations of AngII and Cor increased at T1, T2, and T3 (P < 0.05), and the Ramsay sedation score decreased (P < 0.05). The HR and MAP increased at T1 (P < 0.05) in Group B and Group C. Compared with T0, the BIS, HR, MAP, and Ramsay sedation score, the plasma concentrations of AnglI and Cor were lowered in Group A at T1 (P < 0.05). There was no statistical difference in the use rates of oxytocin, atropine, and ephedrine; the hemorrhage amount, and the neonatal Apgar score (P > 0.05).</p><p><b>CONCLUSIONS</b>Patient-controlled sedation with transcutaneous electrical stimulation of auricular Shenmen (TF4) in cesarean section had obvious sedative effects. It had no adverse effects on puerperal or neonates.</p>
