Effect of Acupressure on Nausea, Vomiting, Anxiety and Pain among Post-cesarean Section Women in Taiwan

The purpose of this study was to examine the effectiveness of acupressure for controlling post-cesarean section (CS) symptoms, such as nausea and vomiting, anxiety perception and pain perception. A total of 104 eligible participants were recruited by convenience sampling of operating schedules at two hospitals. Participants assigned to the experimental group received acupressure, and those assigned to the control group received only postoperative nursing instruction. The experimental group received three acupressure treatments before CS and within the first 24 hours after CS. The first treatment was performed the night before CS, the second was performed 2-4 hours after CS, and the third was performed 8-10 hours after CS. The measures included the Rhodes Index of Nausea and Vomiting, Visual Analog Scale for Anxiety, State-Trait Anxiety Inventory, Visual Analog Scale for Pain, and physiologic indices. Statistical methods included percentages, mean value with standard deviation, t test and repeated measure ANOVA. The use of acupressure reduced the incidence of nausea, vomiting or retching from 69.3% to 53.9%, compared with control group (95% confidence interval = 1.65-0.11; p = 0.040) 2-4 hours after CS and from 36.2% to 15.4% compared with control group (95% confidence interval = 0.59-0.02; p = 0.024) 8-10 hours after CS. Results indicated that the experimental group had significantly lower anxiety and pain perception of cesarean experiences than the control group. Significant differences were found in all physiologic indices between the two groups. In conclusion, the utilization of acupressure treatment to promote the comfort of women during cesarean delivery is strongly recommended.
