Effect of nature based voice therapy in the separation from mechanical ventilation process of intensive care patients

There are harmful physiological and psychological effects besides beneficial effects of mechanical ventilation for patients receiving mechanical ventilation support in intensive care units after surgery. Therefore, it is very important to ensure the stability of the patient's hemodynamic parameters, pain and anxiety level in order to reliably remove the patient from the mechanical ventilator in time and increase the success of the procedure. The research was conducted as a randomized controlled experimental study to investigate the effect of nature-based sound therapy on patients during the separation from mechanical ventilator in a surgical intensive care unit. In the study, 34 patients were separated from the ventilator by closing their eyes for 30 minutes accompanied by nature-based sound therapy between 01/06/2016 - 01/07/2017. The eyes of the other 34 patients were closed without listening to nature-based voice therapy and headphones. Patients' arterial systolic and diastolic blood pressures, heart rate, respiratory counts, oxygen saturation values, pain at both 0th and 30th minutes before and after each ainterventions and the 0th, 10th, 20th and 30th minutes of seperation from the ventilator, and anxiety levels were compared. Data were analyzed by descriptive statistical methods, t test for comparison of parameters between groups, and two way ANOVA for repeated measurements in the SPSS 24.0 program. Findings were interpreted at a significance level of 0.05. In the study; clinical and statistically significant differences were found in the patients in the experimental and control groups for mean systolic and diastolic blood pressures, heart and respiration rates, administration methods and measurement times (p<0.001), their mean oxygen saturations weren't significantly different (p>0.05). Pain, agitation and anxiety levels of the experimental group were found clinically and significantly lower than the control group (p<0.001), there was a statistically significant difference in types of application methods and measurement times (p<0.001).
