The Efficacy of Acu-TENS as an Adjunct Analgesic During USG-MVA

After cleaning the acupoints with alcohol, electrode pads (HC-ROUND-32 2.0) will be placed on the acupoints SP6, ST36, LI4, LR3, according to the locations described in the Standard International Acupuncture Nomenclature. The electrode pads will be connected to a TENS machine (MTRP-00003), in which ipsilateral LI4 and SP36, SP6 and LR3 serve a pair. A pulse rate of 120 Hz, current of 4-12mA, and pulse width of 300µS will be delivered continually for 45 minutes (i.e. from 15 minutes before starting the MVA to 15 minutes after the procedure has completed).

The pads will be stuck on the acupoints for 45 minutes (i.e. from 15 minutes before starting the MVA to 15 minutes after the procedure has completed)."
