Shin, Y.H., Kim, T.I., Shin, M.S., & Juon, H. (2004). Effect of acupressure on nausea and vomiting during chemotherapy cycle for Korean postoperative stomach cancer patients. Cancer Nursing, 27, 267-274.

• Both the control and intervention groups received regular antiemetics.
• The intervention group also received acupressure training, and patients were instructed to perform the finger acupressure maneuver for five minutes on the P6 point at least three times per day before chemotherapy and mealtimes or as needed.
• Both groups received frequent nursing visits and consultations. The intervention was given with first cycle of 5-fluorouracil and cisplatin chemotherapy.

• This study consisted of 40 patients, 20 in the control group and 20 in the intervention group.
• Patients were 47–52 years old.
• All participants were postoperative patients with gastric cancer.

The study took place in a university medical center in metropolitan South Korea. Participants were on inpatient oncology wards.

This study had a nonequivalent control group design for a single cycle of chemotherapy.

• Demographic data, including family background, diagnosis and treatment, and assessment of nausea and vomiting, were recorded.
• The Rhode’s Index of Nausea, Vomiting and Retching was translated into Korean and back-translated to English to ensure equivalency.
• Patients recorded in daily logs their ratings of nausea experience using a four-point scale and intensity of nausea experience during the past 24 hours.

Significant differences existed between the control and intervention groups in the severity of nausea and vomiting, duration of nausea, and frequency of vomiting.

• Self-report has some degree of measurement error.
• Generalizability is limited because of regional study and small sample size.
