The effects of acupressure on pain, anxiety and vital signs in patients undergoing coronary angiography: A randomized and sham-controlled trial.

AIM

This randomised sham-controlled trial aimed to analyse the effects of acupressure on pain, anxiety, and vital signs in patients who underwent coronary angiography.

MATERIALS AND METHODS

After undergoing coronary angiography, 105 patients were randomised into acupressure (n = 35), sham acupressure (n = 35), and control groups (n = 35). Patients in the acupressure group received acupressure on the heart meridian 7 (HT7), large intestine meridian 4 (LI4), and pericardium meridian (PC6) acupoints 30 min after admission to the clinic, for a period of 16 min, whereas those in the sham group received acupressure on locations 1-1.5 cm away from these points. The control group received standard treatment. The patient information form, Spielberger's state anxiety inventory, visual analogue scale, and vital signs follow-up form were used for data collection.

FINDINGS

Consecutive measurements revealed that anxiety levels in the acupressure group were lower than that in the sham and control groups (p < 0.05). In addition, compared to the sham and control groups, the pain scores in the acupressure group decreased significantly after acupressure (p < 0.01). Although there was no significant difference between the pain scores of the sham group before and after acupressure intervention (p > 0.05), the scores of the control group increased significantly over time (p < 0.01). Finally, the vital signs decreased significantly in the acupressure and sham groups after intervention (p < 0.01), but increased significantly in the control group (p < 0.01).

CONCLUSION

The findings of this trial indicated that acupressure is an effective method for reducing anxiety, pain, and vital signs.
