The influence of therapeutic listening on anxiety and fears related to surgery in patients in the preoperative to colorectal surgery: randomized clinical trial

he aim of the study was to evaluate the effect of therapeutic listening on preoperative anxiety and fears related to surgery in patients hospitalized for surgical treatment of colorectal cancer. This is a randomized clinical trial conducted in a general hospital. Participants were randomized in two groups: experimental (n=25) and control (n=25). In the experimental group was performed therapeutic listening. The patients had thirty minutes to talk to the researcher about their experience with hospitalization for the treatment of disease. In the control group patients were informed that they would have some data collected, then the researcher would be gone for thirty minutes and after this range, she would return to complete the research. The dependent variables (alpha-amylase, cortisol, pulse rate, respiratory rate, blood pressure, anxiety state and fears related to surgery) were collected before and after the intervention in experimental group and before and after the break in control group. In comparing the dependent variables in the experimental group compared to the control group in the post-intervention time, no significant differences were identified for any of the variables studied. In comparing the variables in the experimental group and the control group in the pre and post-intervention, there was significant differences only between times in the control group for cortisol (Z=-2,023; p=0,043), pulse rate (Z= -2,121; p=0,034) and fears related to surgery (Z= -2,171; p=0,030), with reduced of these variables. In the relationship between the studied variables, there was a significant difference between state anxiety and the variables cortisol, age, education level and religion; the fears related to the surgery were related to sex, time of confirmation of the diagnosis of colorectal cancer, education level, cortisol, marital status and diastolic blood pressure. Only the variable monthly income showed a significant difference in their distributions in the experimental group and the control group, however, this had no influence on the dependent variables. Most patients report satisfaction with the development of the intervention. It was concluded that, in the preoperative period, under the conditions investigated in this study, the data showed that the measurement of the variables immediately after the intervention of 30 minutes of therapeutic listening did not show the expected reduction of the values of the studied variables; Studies with measures of these variables after a time for the patient to process the effects of the intervention could confirm whether the immediate measurement or one hour after the intervention, for example, would lead to different results. However, there was reduction of cortisol levels, pulse rate and fears related to surgery in the control group, which can be attributed to contact the researcher with these participants during times of data collection
