Anxiety is a common preoperative problem in cesarean section candidates. Nonpharmacologic anxiety control has been demonstrated to be more suitable in pregnant women. The current study was a randomized, single-blind clinical trial which evaluated the effect of acupressure on preoperative C-section anxiety. In this study, 60 patients facing surgery were randomly divided into two groups of 30 patients each. Those patients in the intervention group received simultaneous acupressure at the Yintang and HE-7 acupoints for 5 minutes before surgery, and patients in the control group received intervention at a sham acupoint. The anxiety level of patients was preoperatively assessed twice using the Spielberger's State-Trait Anxiety Inventory. The mean anxiety scores of the two groups were shown to be insignificantly different before the intervention (p = 0.859), whereas a significant difference between the mean anxiety scores of the two groups was observed after the intervention (p = 0.001), suggesting that acupressure reduced the anxiety of patients before surgery.
