FULL TITLE: The efficiency and duration of the analgesic effects of musical therapy on postoperative pain.
OBJECTIVES: The aim of this study was first to find out the effect of music therapy on postoperative analgesia and second to determine the duration of its effect. METHODS: Seventy patients who were undergoing elective cesarean delivery were enrolled. The patients were randomly allocated into two groups as follows: In Group 1, patients listened to music through a headphone for one hour after surgery, while in Group 2, patients did not listen to any music during the same period. In the postanesthesia care unit, patients were connected to a Patient Controlled Analgesia (PCA) device. The PCA device (tramadol 3 mg/ml) was set to deliver a bolus of 20 mg, with a lockout interval of 15 min and 4-hour maximal dose of 150 mg. Postoperative pain was assessed with a visual analog scale (VAS) and consumption of tramadol was recorded at 4, 8, 12, 16, 20 and 24 hours. RESULTS: There was a significant decrease in Group 1 with respect to PCA delivery frequency at the 4th hour postoperatively (p<0.05). Concerning the postoperative tramadol consumption, values measured at the 4th hour were significantly lower in Group 1 (p<0.05). The total amount of tramadol consumption and additional analgesic use in the postoperative 24 hours were again lower in Group 1 when compared with Group 2 (p<0.05). All VAS values were lower in Group 1 when compared with Group 2 (p<0.05). CONCLUSION: We suggest that music therapy given after surgery decreases postoperative pain in the first 24 hours and the analgesic consumption during the first four hours.
