Analgesia by Single or Dual Acupoints Stimulation After Radical Mastectomy
- Conditions
- Pain
- Interventions
- Device: acupoint stimulationDevice: no stimulation
- Registration Number
- NCT02741726
- Lead Sponsor
- Zhihong LU
- Brief Summary
The purpose of this study is to compare the effects of dual acupoints and single acupoint transcutaneous electrical acupoint stimulation (TEAS) pretreatment on incidence of Post-Mastectomy Pain Syndrome(PMPS) in patients undergoing operation of breast cancer.
- Detailed Description
Patients were randomly assigned to three groups, receiving 30min TEAS before anesthesia respectively. The acupoints of dual point group are bilateral Neiguan points(PC6) combined with Danzhong point(RN17), single point group is bilateral Neiguan points(PC6), and the false stimulation group only attach electrodes without electric current. The frequency of TEAS is set to 2/15 Hz. Intraoperative anesthetic dosage of propofol and remifentanil was recorded. Three and six months after surgery, follow-up about chronic pain was made by telephone or face-to-face using the follow-up questionnaire. The adverse events were recorded.

Group Intervention Description dual acupoint stimulation acupoint stimulation The acupoints of dual point group are bilateral Neiguan points(PC6) combined with Danzhong point(RN17), electric stimulation was given through electrode attached to the acupoints. single acupoint stimulation acupoint stimulation The acupoints of single point group is bilateral Neiguan points(PC6), Electric stimulation was given through electrode attached to the acupoints. no stimulation no stimulation false stimulation group only attach electrodes without electric current.
- Primary Outcome Measures
Name Time Method Incidence of chronic pain six months after surgery six months after surgery
- Secondary Outcome Measures
Name Time Method Incidence of chronic pain three months after surgery three months after surgery Remifentanil consumption during the surgery from start of surgery to end of surgery, at an average of 2.5 hours the time to the first verbal response end of the anesthetics infusion to patient's first response to verbal command,on an average of 30 minutes the time to extubation end of the anesthetics infusion to extubation,on an average of 30 minutes postoperative nausea and vomiting within 24 h after surgery end of surgery to 24 hours after surgery,on an average of 24 hours respiratory depression within 24 hours after surgery end of surgery to 24 hours after surgery,on an average of 24 hours Visual Analogue Scale scores within 24 hours after surgery end of surgery to 24 hours after surgery,on an average of 24 hours demand of rescue analgesics within 24 hours after surgery end of surgery to 24 hours after surgery,on an average of 24 hours pain score at 6m after surgery six months after surgery patients' s satisfaction scores on analgesia within 24 hours after surgery end of surgery to 24 hours after surgery,on an average of 24 hours pain score at 3m after surgery three months after surgery
