Abstract:
This quasi experimental, aimed to examine effects of the preoperative information giving with acupressure program on postoperative nausea, vomiting, and retching between the experimental group, and the control group at the 4, 8, and 24 hours after surgeries. The sample of 60 female treated with gynecologic surgery was recruited from BMA Medical College, and Vajira Hospital. The control group received routine nursing care while the experimental group received the preoperative information giving with acupressure program that consisted of four steps; assessment of symptoms experience, information giving, acupressure on P6 acupoint, and evaluation of the program. The collecting instruments used for data were the Rhodes Index of Nausea, Vomiting and Retching (INVR) (Rhodes, 1999).The reliability of this instrument with Conbachs alpha coefficient was .89. Data were analyzed by descriptive statistics, t-test, and F-test. The results were as follows : 1. The nausea, vomiting, and retching in experimental group at 4, 8, and 24 hours after surgeries were significantly decreased respectively (p<.05), by highest score at 4 hours and minimum score at 24 hours, while control group were increased, respectively. 2. The nausea, vomiting, and retching at 4, 8, and 24 hours after surgeries of the experi- mental group were significantly lower than those of the control group (4 hours: X-bar experiment = 1.67, X-bar control = 4.00, t = 2.78, p<.05; 8 hours: X-bar experiment = 1.27, X-bar control = 6.07, t = 4.58, p<.05 and 24 hours: X-bar experiment = 0.17, X-bar control = 6.10, t = 6.40, p<.05).
