摘要
Aim and objective. To examine the effect of relaxation therapy on reducing patient anxiety and pain before and after total joint replacement. %26lt;br%26gt;Background. Despite the use of analgesics, patients may feel anxiety and pain before and after surgery, delaying their recovery. %26lt;br%26gt;Design. An experimental control group pretest-post-test quasi-experimental design was employed. %26lt;br%26gt;Method. Subjects (n = 93) recruited from a medical centre in Taipei, Taiwan, from November 2006-March 2007 were randomly assigned to experimental (n = 45) and control (n = 48) groups. Subjects in the experimental group received relaxation therapy from the day before surgery to the third postoperative day. Researchers helped participants listen to a breath relaxation and guided imagery tape for 20 minutes daily. A pain and anxiety scale questionnaire, the State-Trait Anxiety Inventory questionnaire, blood pressure and heart rate were monitored before and after intervention. %26lt;br%26gt;Results. The average age of the 93 patients was 71 0 (SD 11 1) years. The least pain severity scores in the experimental were lower than those in the control group (p %26lt; 0 05) but both experienced the same level of worst or average pain (p %26gt; 0 05). The mean difference in the pain score before and after intervention in the experimental group on the pre-op day (t = 2 675, p = 0 009) and post-op day one (t = 3 059, p = 0 003) was greater than that in the control group (0 48 SD 0 94 vs. 0 10 SD 0 30 and 0 93 SD 1 46 vs. 0 20 SD 0 71, respectively). The two groups differed significantly in systolic blood pressure (F = 6 750, p %26lt; 0 05) but not in mean blood pressure, heart rate, or State-Trait Anxiety Inventory scores (p %26gt; 0 05). Patients reported that relaxation therapy helped them relax and promoted sleep. %26lt;br%26gt;Conclusion. Relaxation therapy could complement analgesics to help postoperative patients better manage pain and anxiety. %26lt;br%26gt;Relevance to clinical practice. Clinical practice should include complementary relaxation therapy to alleviate pain and anxiety in patients with joint replacement.
