Brief Summary

Chemotherapy induces nausea and vomit for some large patients. But, some chemotherapy protocol has a high indices of the incidence as observed in a combination of Anthracycline and Cyclophosphamide (AC). To prevent this symptoms, some medication can be used as Ondansetron. By other hands, the traditional acupuncture on Chinese Medicine have been used a PC6 point to avoid nausea and vomit. More recently, a transcutaneous electric nerve stimulation (TENS) also has been used for this application. Our study will test the TENS applied on PC6 point with two different frequencies (high and low) to evaluated the nausea and vomit inhibition effects.

Outcome Measures

Primary Outcomes (1)

  • Cumulative index of nausea

    The 24-hour follow-up record of symptoms of nausea and vomiting will be performed using a form developed from the MASEM anti-emetic instrument (MAT), especially for the present study. This form includes a diary to record emetic events within 24 hours after the administration of chemotherapy. Thus, we will evaluate: the cumulative index of nausea and vomiting over 24 hours after the infusion of the first cycle of high grade emetic chemotherapy.Participants will be instructed to fill out the instrument and take the questionnaire home, bringing it back to the investigators when they return to the outpatient clinic for another round of chemotherapy.

    Cumulative index of nausea in the first 24 hours after an infusion of chemotherapy.

Secondary Outcomes (5)

  • Cumulative index of episodes of vomiting

    Cumulative index of episodes of vomiting in the first 24 hours after an infusion of chemotherapy.

  • Intensity of nausea symptoms

    Intensity of the symptom of nausea within the first 24 hours after infusion of chemotherapy.

  • Severity of vomiting episodes

    Severity of vomiting episodes within the first 24 hours after chemotherapy infusion.

  • Need for rescue antiemetic

    Need for rescue antiemetic within the first 24 hours after chemotherapy infusion

  • Edmonton Symptom Assessment Scale

    At the end of 24 hours, you will be asked to complete the Edmonton Symptom Assessment Scale

Study Arms (3)

Placebo Group

PLACEBO COMPARATOR

Placebo Group: In this group the participants received TENS with frequency of 75Hz, pulse duration of 200 microseconds. The stimulation time will be for only 10s.

Device: Placebo Group

Low Frequency Group

EXPERIMENTAL

Low Frequency Group: In this group the TENS will be adjusted with frequency of 10Hz, pulse duration of 200 microseconds. The stimulation time will be 30 minutes and the intensity will be constantly adjusted in order to keep as high as possible within the tolerance threshold of the patient.

Device: Low Frequency Group

High Frequency Group

EXPERIMENTAL

High Frequency Group: In this group the TENS will be adjusted with frequency of 150Hz, pulse duration of 200 microseconds. The stimulation time will be 30 minutes and the intensity will be constantly adjusted in order to keep as high as possible within the tolerance threshold of the patient.

Device: High Frequency Group

Interventions

In this group, the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the opposite arm of the chemotherapy infusion, but in this group the electrical stimulation will be performed just by 10 seconds and turn off for all reminiscent time of the protocol.

Placebo Group

In this group the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the arm opposite the chemotherapy infusion. The electrical stimulation will be continued for all time secession. The electrical pulse parameters will be setting according describe early.

Low Frequency Group

In this group the TENS will be administered by 30 minutes prior to chemotherapy administration with the stander electrodes positions, in the arm opposite the chemotherapy infusion. The electrical stimulation will be continued for all time secession. The electrical pulse parameters will be setting according describe early.

High Frequency Group

Model Details: The selection of the investigated will be characterized as non-probabilistic with a convenience approach, whose patients will be included in the study sequentially until the necessary sizing has been achieved. Patients will be included sequentially for convenience (according to the inclusion and exclusion criteria) and non-probabilistic. The included individuals will be randomly randomized by Random Allocation System software in three groups, 1) placebo group; 2) High Frequency Group; 3) Low Frequency Group.
