nctId: NCT06341270 id: 2024HX1564 briefTitle: Efficacy of TEAS on Postoperative Pain and Recovery in Patients Undergoing Hepatectomy overallStatus: NOT_YET_RECRUITING date: 2024-04-20 date: 2026-04-20 date: 2026-12-20 date: 2024-04-02 date: 2024-04-18 name: West China Hospital class: OTHER briefSummary: The purpose of this study is to access the effect of transcutaneous electrical acupoint stimulation on postoperative pain in patients undergoing hepatectomy conditions: Liver Cancer studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Patients who meet the enrollment criteria will be randomized 1:1 to either the transcutaneous electrical acupoint stimulation (TEAS）or the sham groups using a computer-generated random number table. After the randomization, use the opaque envelope, hide each group envelope into an opaque envelope, the envelope outside the code, will be sealed to the researcher, when the study, if the inclusion criteria, then open the corresponding numbered envelope, and intervene according to the group scheme in the envelope. primaryPurpose: TREATMENT masking: DOUBLE maskingDescription: Blinding of participants will be maintained throughout the observation period. The sham group will receive electrode attachment but without stimulation,Throughout the study, for adequate blinding, an opaque tape will be applied to the patient's skin above the electrodes, and the patient's target acupoints will be wrapped in a blanket. All patients will be informed that they might or might not feel a tingling sensation around the acupoints when the TEAS device is working. The patients should not be unblinded until the statistical analysis of the study data is completed. whoMasked: PARTICIPANT whoMasked: OUTCOMES_ASSESSOR count: 524 type: ESTIMATED name: transcutaneous electrical acupoint stimulation name: sham transcutaneous electrical acupoint stimulation measure: The incidence of moderate to severe pain (NRS ≥ 4) during movement (i.e. cough or take three deep breaths) at 24 hours after surgery measure: The incidence of moderate to severe pain (NRS ≥ 4) during movement (i.e. cough or take three deep breaths) at 48 and 72 hours after surgery measure: The incidence of moderate to severe pain (NRS ≥ 4) at rest at 24, 48 and 72 hours after surgery measure: Pain scores of movement-evoked pain at postoperative 24,48 and 72 hours measure: Pain scores of pain at rest at 24, 48 and 72 hours postoperatively measure: The cumulative morphine consumption at 24, 48, and 72 hours postoperatively measure: The incidence of postoperative nausea and vomiting during the first 24,48,72 hours measure: The incidence of a composite of postoperative pulmonary complications during hospitalization measure: Quality of Recovery Scale Score at 24, 48, and 72 hours after surgery measure: Time of Bowel function recovery measure: Length of hospital stay measure: The postoperative sleep quality score measure: The anxiety and depression scores measure: The incidence of chronic postsurgical pain (CPSP) sex: ALL minimumAge: 18 Years maximumAge: 80 Years stdAges: ADULT stdAges: OLDER_ADULT facility: West China Hospital city: Chengdu state: Sichuan zip: 610041 country: China name: Chunling Jiang, PhD role: CONTACT phone: 18980601096 email: jiang_chunling@yahoo.com lat: 30.66667 lon: 104.06667 hasResults: False
