“An evaluation of the Sea-Band in alleviating nausea and vomiting in patients receiving chemotherapy”
Department of Medical Oncology University of Southampton.
PURPOSE: To assess by means of a single blind cross-over model if acupressure by Sea-Band on Wrist point (active) versus acupressure on an ankle point (sham) reduces nausea and vomiting in patients receiving chemotherapy. METHOD: Patients receiving chemotherapy at the RSH Hospital were asked to participate in the study during their next two treatments. For one treatment they wore the bands on both wrists continuously for seven days, and for the other treatment they wore the bans on both ankles. The ankle and wrist treatments were randomised. While wearing the bands the patients were asked to record their symptoms daily in a diary card. After wearing the bands at both sites the patients were asked to complete a questionnaire concerning their preference for the wrist versus ankle treatments. Throughout the study the patients still received their usual pharmacological anti-emetics. RESULTS: 105 patients entered the study; 67 patients completed the study, 38 patients withdrew. Questionnaire analysis found that 49% of patients found P6 acupressure provided better control of nausea and vomiting, 17% found sham acupressure provided better control and 34% found no difference between the two. The diary cards indicated that P6 was more effective than sham acupressure in alleviating sickness, nausea, mood and overall condition in the high emetic intensity group. CONCLUSION: P6 acupressure is a good method to complement conventional anti-emetic therapy for people having chemotherapy, particularly that of a high emetic intensity. It is recommended that it should be included into a standard anti-emetic protocol for chemotherapy, subject to further work on it.
