Abstract: Having seen pregnant women pressing the P6 point as a preventative
for morning sickness, stimulation of this point for 5-10 minutes by
invasive (manual or electrical acupuncture) or non-invasive (transcutaneous
electrical stimulation or acupressure) means was studied as an antiemetic.
In well controlled studies it was shown that acupuncture administered
before the opioid premedication significantly reduced postoperative
sickness for 6-8 hours. Non-invasive methods were effective for a shorter
period of time, with nausea and/or vomiting often occurring after 2 hours.
To be effective the treatment has to be given before the opioid.
Its effect
can be abolished by local anesthesia. Stimulation of a dummy point near the
elbow is ineffective.
While acupressure reduces morning sickness, the
pressure has to be applied for 5 minutes every 2 hours. There is probably a
large psychological element in this. The most rewarding results are
obtained when P6 stimulation is used in conjunction with standard
antiemetics before cancer chemotherapy. Here again the invasive approach is
more effective than non-invasive. Recent studies have involved
self-stimulation using a portable battery-operated square wave stimulator
fixed at 10 Hz, and a large EKG surface electrode on the P6 point.
Stimulation is applied for 5 minutes every two hours.
While modern
antiemetics can control vomiting, they are relatively ineffective against
nausea, but this can be controlled by regular use of the stimulator. The
results are most promising. |
