RESUMO
Today endoscopy is veray efficient but invasive gastrointestinal diagnostic method that can be frightening and painful. Common physiologic reaction to this is anxiety resulting in an increase in blood pressure. Previous studies have indicated that patients may benefit by music through reducing pain and anxiety. The purpose of this study was to determine the effect of music on patients' anxiety by checking their blood pressure. Statistical analysis using ANOVA and T-test were used to compare differences in SPSS soft ware. This study was an experimental clinical trial. Subjects were eligible for the study as they had undergone endoscopic and colonoscopic examinations for the first time, they were 30-60 years old, did not have any cardiac dieases and hypertension and had been randomly assigned into two groups. One group listened to music and the other one did not. Study results indicated that patients who listened to music had lower systolic and diastolic blood pressure and higher O[2] saturation than control group but it was not statistically significant. The findings also showed that patients who had colonoscopy had higher blood pressure compared to the patients who had endoscopy. Slow music had a positive effect on blood pressure decrease, O[2] saturation increase, patients' tolerance of procedure, cooperation and reduction of procedure time in the experimental group
