Der Einfluss von prä- und intraoperativer Musikdarbietung auf die postoperative Befindlichkeit

This thesis deals with the question of using pre- or intraoperative music in patients to improve the well-being and quality of sleep and for reducing postoperative pain. With this relatively inexpensive tool the postoperative well-being could be easily increased and painkillers could be saved. Numerous studies on this subject showed different results: some showed significant positive results, others remained inconclusive compared to the control group. Yet, further studies indicated an apparently negative effect of music on postoperative pain. Patients between the age of 18 and 75 and an ASA classification not greater than ASA III, about to undergo breast surgery or a gynecological laparoscopy, were selected for this study. Preoperatively, the sleeping habits of the last four weeks have been analysed with a PSQI questionnaire, as well as the presence and severity of depressions (BDI). Subsequently, the patients were randomized into groups with pre- or intraoperatively music or no music in the control group. By way of further sleep questionnaire (SF-A) and the visual analog scale (VAS) was examined postoperatively if there was an effect of music on sleep behavior, well-being and pain. Pre- or intraoperative music application seems, if anything, to have only a very weak effect on above-mentioned parameters. However, due to the size of each group and the associated allocation of poor sleepers and patients with moderate depression, no significant statement in the majority of cases could be made. Patients with depression and poor sleep are often found in the control group again. However, a significant correlation was made for the well-being in the evening and mental balance. This was indicated by the observation that the control group got worse results than the group with preoperative or intraoperative music performance. Clinical implication: Patients who undergo elective surgery should be encouraged to bring relaxing music according to their own personal taste to the clinic. This way, a better mood and a relaxing situation can be achieved, at least on the evening prior to the surgery. Bringing personal music players to the theatre cannot be recommended currently, as the potential risk of liability claims upon loss or damage of the patients personal devices is not justifiable by a proven benefit for the postoperative stage.
