Review Comparative Study[Music therapy effectiveness to decrease anxiety in mechanically ventilated patients].
The aim of this review is to find out whether or not music therapy is an effective nursing intervention to decrease anxiety and promote relaxation in ventilator-dependent patients. For the purpose of this review, relaxation has been considered as a reduction in state anxiety and physiologic signs (heart rate, blood pressure or respiratory rate). A comprehensive search has been conducted in electronic databases (Cochrane Library, Medline, CINHAL, Embase and PsycLit) in order to identify systematic reviews on music therapy effectiveness or randomised control trials that compare the effectiveness of music therapy versus no music or other relaxation techniques in patients receiving ventilatory assistance. ⋯ Some methodological limitations make their results be not fully reliable and therefore, it has not been possible to reach a satisfactory answer. Further and more rigorous research is needed on this area, as there is not enough valid research to conclude that music therapy is an effective nursing intervention for decreasing patients' anxiety. As it causes no harm and is a relatively inexpensive intervention, it would be worth exploring its effects on different kind of outcomes and settings.
