the effect of music therapy on patients' blood pressure in endoscopy unit in bou-ali hospital, ardebil

background: today, endoscopic evaluation of digestive system is an important diagnostic approach in gastrointestinal diseases. as it is an invasive method, it causes fear and anxiety in patients. the current study was fulfilled to evaluate the effect of music therapy during endoscopy on the anxiety of patients by measuring blood pressure. methods: this is an experimental study of single blind clinical trial type. the participants were patients in the endoscopy unit in the age range of 30 to 60, undergoing endoscopy or colonoscopy for the first time with negative history of cardiovascular diseases or hypertension. cases were randomly placed in two groups: the experiment group who listened to music during the procedure and the control group who did not listen to music during the procedure. the patients’ blood pressures, arterial blood oxygen saturation during the procedure as well as their demographic information were recorded. finally, the data was analyzed using t- test and analysis of variance by spss software. results: our results demonstrated that patients of the experiment group had lower systolic and diastolic blood pressure and higher arterial blood oxygen saturation comparing to control group, but the difference was not statistically significant. also it was showed that the blood pressure altered more in the patients underwent colonoscopy comparing those underwent endoscopy. the difference was statistically significant. (p= 0.034) mean duration of endoscopy procedure in control group was higher than that of the experiment group. conclusions: light music has useful effects on cooperation and tolerance of patients during the procedure by regulating blood pressure and oxygen saturation of blood and reducing the duration of the procedure. key words: music, endoscopy, blood pressure, anxiety ijnmr
