Abstract Title:
Guided imagery relaxation therapy on preoperative anxiety: a randomized clinical trial.
Abstract:
OBJECTIVE: to evaluate the effect of relaxation therapy with guided imagery on state anxiety and cortisol in the immediate preoperative period in patients submitted to bariatric surgery by videolaparoscopy.METHOD: a randomized, triple-blind clinical trial in a large teaching hospital in the interior of Minas Gerais. Twenty-four patients who would undergo video-laparoscopic bariatric surgery were randomly allocated in two groups, namely 12 in the control group and 12 in the experimental group. State anxiety was assessed by the State-Trait Anxiety Inventory, and blood cortisol levels were measured before and after the intervention or standard care. Descriptive analyzes were used for the quantitative variables and Student's t-test for independent samples, in the analysis of the differences between the state anxiety scores and cortisol levels.RESULTS: the experimental group presented a statistically significant reduction of the state anxiety scores (p = 0.005) as well as of cortisol levels (p
