Wunsch JK, et al. - In this pilot study, researchers assessed the acceptability and feasibility of auricular acupuncture (AA) as a treatment for preoperative anxiety (PA) in preparation for a subsequent randomised controlled trial. This study included female patients who were scheduled for ambulatory gynaecological surgery and were offered AA for treatment of PA. Based on the findings, AA was proved to be an acceptable and feasible treatment option for preoperative anxiety. The results were used for the sample size calculation of a subsequent randomised controlled clinical trial.
