been debated during the last decade as nausea and vomiting
has been identified as a major quality factor from the patient’s
point of view.36 Thus, self-reported nausea experience may
have some degree of measurement error, such as errors related
to memory lapse of nausea and vomiting. Second, the finding
has limited generalizability because this study was regional and
small samples were involved.
This study suggests a need for further research to complement
these limitations. Further study of acupressure as a
complementary therapy for chemotherapy-induced nausea
should be carried out in a large number of cases with a randomized
control design. We also need to clearly understand
the multifactor etiology of postoperative chemotherapyinduced
nausea and vomiting that may be considered as
other confounding factors. Finally, nurse educators and clinical
nurses should recognize information on nonpharmacologic
management of nausea and vomiting, such as acupressure
techniques and need to develop educational tools
(eg, pamphlets, audiovisual tapes) for training nursing
students, patients, and families on the use of acupressure
techniques.
