About this study
Official title: Electroacupuncture Analgesia for Endoscopic Ultrasound (EUS): a Prospective, Randomized, Double-blinded, Sham-controlled Study
Endoscopic ultrasound (EUS) has evolved to become an important diagnostic tool and its interventional role is rapidly expanding. In order to improve patient's comfort and satisfaction during and after procedure, the use of sedation is usually recommended. However, sedation may be associated with serious adverse events of including hypotension, aspiration and respiratory depression. Moreover, the cost of performing the procedure would be increased due to the costs of the medications and the need of additional personnel in monitoring of the patient. As a result, the drive to seek alternative and safer approaches of pain-relief during EUS is ever present. Electroacupuncture (EA) has been used in Traditional Chinese Medicine (TCM) for more than 2000 years. The benefits and success of EA in treatment of acute and chronic pain of various origins have been well-recognised. Many researches have been performed to address the role of EA in treating pain and anxiety during OGD and colonoscopy. However, only limited data is availabe in the Chinese and the Western literature concerning the use of EA in EUS. Therefore it is worthwhile to conduct a well-designed study to evaluate the role of EA in treating pain during EUS.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ElectroacupunctureProcedure or surgery
| Study group | Role | What they receive |
|---|---|---|
| Electroacupuncture | Active comparator | Patients randomized to the experimental group will receive EA at acupoints relevant to the treatment of abdominal pain and anxiety. Selection of these acupoints is based on a consensus between the acupuncturist of the study (Leung WW) and several professors of the Diploma Course of Clinical Acupuncture of the School of Professional and Continuing Education, University of Hong Kong. Receives: Procedure: Electroacupuncture |
| Sham Acupuncture | Placebo comparator | Patients randomized to the control group will receive Sham acupuncture with sterile blunt-tip needles Receives: Procedure: Electroacupuncture |

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Electroacupuncture in people with Patients Undergoing Endoscopic Ultrasound, run by Chinese University of Hong Kong at 1 site in Hong Kong.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Consumption of propofol (time frame: 1 day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02066194, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2017; AzTrials last refreshed its copy on 29 Oct 2026.
