Brief Summary:

In this prospective nonrandomized study the investigators are going to investigate whether auricular acupuncture with indwelling fixed needles is feasible for treatment of preoperative anxiety.

Patients, scheduled for ambulatory gynecologic surgery, will be asked, if they wish to receive auricular acupuncture (AA) against preoperative anxiety. The patients who will not wish AA, will be asked to take part in questioning (State-Trait-Anxiety-Inventory (STAI) questionnaire) and will form the control group. The preoperative anxiety using STAI, as well as the duration and quality of sleep on the night before surgery, the incidence of side effects, blood pressure and heart rate will be the outcome measures in this study.

Arm Intervention/treatment
Active Comparator: Auricular acupuncture + standard therapy
Patients, who will wish acupuncture, will receive this intervention, in addition to standard therapy
Device: Auricular acupuncture
Five ear acupuncture points: MA-IC, MA-TF1, MA-SC, MA-AT1 and MA-TG will be needled bilaterally in patients, who will wish to receive AA. Indwelling fixed "New Pyonex" needles (length: 1.5 mm, diameter: 0.22 mm; Seirin Corp., Shizuoka City, Japan) will be used for AA.

No Intervention: Standard therapy alone
Patients who do not wish acupuncture will be asked if they will fill in the study questionnaire

Primary Outcome Measures :
  1. Situational anxiety_1 [ Time Frame: Situational anxiety_1 will be measured on the day before surgery before auricular acupuncture ]
    State (situational) anxiety will be measured using State-Trait-Anxiety Inventory (STAI).

  2. Situational anxiety_2 [ Time Frame: Situational anxiety_2 will be measured and in the evening of the day before surgery ]
    State (situational) anxiety will be measured using State-Trait-Anxiety Inventory

  3. Situational anxiety_3 [ Time Frame: Situational anxiety_3 will be measured on the day of surgery immediately before the operation ]
    State (situational) anxiety will be measured using State-Trait-Anxiety Inventory

Secondary Outcome Measures :
  1. Heart rate [ Time Frame: On the day of surgery before the surgery ]
  2. Blood pressure [ Time Frame: On the day of surgery before the surgery ]
