Abstract
Objective: To verify the effects of classical music in children hospitalized in the Intensive Care Unit and Pediatric Ward. Methods: It is a quasi-experimental study, a quantitative approach. Four children under 36 months participated, exposed to 40 minutes daily for five days to the Mozart baby repertoire, respecting the loudness of 45 decibels (dB). It used a structured form to record heart rate, respiratory rate, saturation, temperature, pain scale. Inclusion criteria were exposure to invasive procedures in the last six hours, oxygen inspiratory frequency (FiO2) less than or equal to 21% and unattended ventilation. An electrode was applied to the biceps brachii muscle and muscle tension was analyzed on the first and fifth days. The registration made by the electromyography Trigno 8 Channel Wireless. Exposure to stress was assessed by test tape saliva on the first and fifth days, on the Coroco Meter (Nipro Corporation - Japan). Results: There was a reduction in hemodynamic values with p-value less than 0.01, pain with p-value less than 0.001. Electromyography verified a reduction in electrical impulses, influencing the rate of firing for muscle fibers with muscle relaxation. Conclusion: Music stimulates different brain areas and can be used to assist therapeutic segments.
