Effect of Short-Term Yoga-Based-Breathing on Peri-Operative Anxiety in Patients Undergoing Cardiac Surgery.

Background: Peri-operative anxiety in patients scheduled for cardiac surgery is detrimental. This study evaluated the effect of short-term yoga based-breathing with different variations on peri-operative anxiety.

Materials and methods: A prospective randomized controlled study was conducted in patients aged 20-60 years scheduled for major cardiac surgery. Patients in Yoga group were trained for yoga based-breathing with different variations for 5 days; no intervention was done in controls.

Results: We analyzed twenty patients in each group. Anxiety scores measured at baseline, presurgery, and postsurgery were entered as the within-subjects factor; group status was entered as the between-subjects factor in the RMANOVA. Baseline demographics and anxiety scores were comparable. The short-term yoga-based breathing exercise-training program had a statistically significant effect on state (F = 13.45, P < 0.0001), Trait (F = 13.29, P < 0.0001) and total anxiety scores (F = 29.44, P < 0.0001) at different time points for yoga over control group.

Conclusion: Short-term yoga-based breathing for 5 days lowers presurgery and postsurgery anxiety in patients undergoing cardiac surgery.
