The antimentic effect of AP at PC 06 can be abolished by local anaesthesia of the point. The most rewarding results were with PC 06 stimulation used with standard antiemetics before cancer chemotherapy. Here also, invasive AP was more effective than non-invasive AP . Self-use of TENS was studied recently. Using a portable battery-operated square wave stimulator fixed at 10 Hz, TENS was used for 5 min every 2 h via a large EKG surface electrode on the PC 06 point.
Modern antiemetics can control vomiting, but they are relatively ineffective against nausea.
The combination of antiemetic drugs with invasive AP gives the best results in severe cases . Non-invasive stimulation of the PC06 antiemetic AP point in cancer chemotherapy . The use of large diffuse low impedance electrodes simplifies the technique. Application of Sea Bands every 2 h prolongs the antiemetic action. Local anaesthesia blocks the antiemetic action of AP at PC06 .
