Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objectives: To demonstrate the use of acupuncture-type transcutaneous electrical nerve stimulation (acu-TENS) during transvaginal ultrasound-guided oocyte retrieval (TUGOR) will reduce 50% of the intensity of pain experienced by women.

Hypothesis to be tested: Does the use of acu-TENS reduce 50% of pain in TUGOR? Design and subjects: A prospective randomized control trial will be carried out at the Department of Obstetrics and Gynaecology, Prince of Wales Hospital. 144 women undergoing TUGOR will be randomized to receive acu-TENS or sham acu-TENS for pain control during TUGOR.

Study instruments: During the TUGOR procedure, ultrasound of the pelvis will be performed by Aloka ProSound SSD-3500SX device (Japan). Each follicle will be pierced using a single lumen ovum aspiration needle or a double lumen ovum aspiration catheter (COOK Medical, UK) under ultrasound guidance. Acu-TENS will be done using MTR+ Myolito Multifunctional Stimulator.

Main outcome measures: Primary outcome is the pain score before and during TUGOR. Secondary outcomes include (1) other pain level parameters including pain control satisfaction, surgeon's assessment of the patient co-operation score and patient intraoperative pain; (2) stress and anxiety levels, Stait Trait Anxiety Inventory, General Health Questionnaire, Beck Depression Inventory, and saliva cortisol; (3) patient's satisfaction measured by Client Satisfaction Questionnaire and satisfaction score on pain control; (4) difficulty in retrieving oocytes; (5) IVF parameters; (6) safety profile; and (7) bias assessment.

Data analysis: Data analysis will be performed using Statistical Packages of Social Sciences for Windows.

Expected results: The investigators expect that acu-TENS will reduce 50% of pain in TUGOR.

Acu-TENS

Acu-TENS treatment

Group Type EXPERIMENTAL

Acu-TENS

Intervention Type OTHER

This protocol makes use of the acu-TENS treatment on the acupoints Hegu (LI4), Zusanli (ST36), Sanyinjiao (SP6), and Taichong (LR3). After cleaning the acupoints with alcohol, electrode pads (HC-ROUND-32 2.0) will be placed on the acupoints according to the locations described in the Standard International Acupuncture Nomenclature. The electrode pads will be connected to a TENS machine (MTR+ Myolito Multifunctional Stimulator MTRP-00003), in which ipsilateral LI4 and SP36, SP6 and LR3 serve a pair. A pulse rate of 120 Hz, current of 3-5 mA, and pulse width of 300µS will be delivered continually during TUGOR.

Sham acu-TENS

Sham acu-TENS without electric current

Group Type SHAM_COMPARATOR

Sham acu-TENS

Intervention Type OTHER

In the sham acu-TENS, within the same time interval, TENS pads will be placed on the same acupoints, connected to the machine, but without electric current.
