 The purpose of this study is to investigate whether a psycho-cognitive nursing intervention including relaxation, guided imagery, touch and music listening can improve the clinical and psychological outcome of critically ill patients. The investigators hypothesize that, patients who receive the proposed psycho-cognitive nursing intervention will report lower stress, less pain and have altered level of stress neuropeptides in peripheral blood, lower levels of inflammatory molecules, less complications and better self reported lived experience than patients who receive standard care alone.
