The Effect of Progressive Muscle Relaxation Exercises After Endotracheal Extubation on Vital Signs and Anxiety Level in Open Heart Surgery Patients

Abstract

Objective: The purpose of this study was to examine the effects of the exercises of progressive muscle relaxation (PMR) on vital signs and anxiety level after endotracheal extubation in open heart surgery. Materials and Methods: This study was carried out as quasi-experimental, pre-test, and post-test with a control group. The study recruited 30 experimental and 30 control group open heart surgery patients, who met the inclusion criteria, from a cardiac and vascular surgery clinic of a university hospital. PMR exercises, which were taught before the surgery, were implemented after the surgery in the intensive care unit simultaneously with endotracheal extubation. The vital signs of the patients were monitored for the first 30 min. The anxiety levels were measured after 30 min of extubation with state anxiety inventory. Results: The lower rates of heartbeat, breathing, arterial blood pressure, and anxiety were observed in the experimental group in all measurements (first 30 min after endotracheal extubation), and the differences were statistically significant in favor of the experimental group (p<0.05). Conclusion: The study showed that the relaxation exercises after endotracheal extubation in open heart surgery patients was effective in improving vital signs and reducing anxiety level.
