| Summary: | 碩士 === 慈濟大學 === 護理學系碩士班 === 101 === The purpose of this study was to determine the effect of music on opioids dosage and peri-operative physiological responses in patients undergoing total knee replacement surgery, experimental research design and purposive sampling were used in this study,for which the subjects were received total knee replacement surgery of a medical center in Hualien orthopedic ward, operation waiting room and recovery room for the sampling locations, randomly assigned patients to music group (15 patients) and control group (15 patients). The music group participants received 30 minutes music intervention in the ward and operation waiting room, and post-operative recovery room for 60 minutes later,but the control group participants received conventional care.A structured questionnaire was used to collect data. The researcher conducted the music intervention and assistance questionnaires.measurement tools containing three parts: the demographic characteristics, State Anxiety Inventory, Biological index; dose of painkillers are measured into account from post-operative recovery room and postoperative twelve-hours, follow the doctor's orders use of analgesic drugs dose according to the patient complained of pain ,analgesic demand then opioids drugs conversion formula translated into the morphine dose for
collection;perioperative physiological responses was recorded by diological signal recording system(Solar 8000) and Visual Analog scale for pain by way of repeated measurements. The record blood pressure, heart rate and respiratory rate on pre- ward , before patient transfer to a waiting area.Arrived pre-op waiting room,the conventional 15 minutes, 30 minutes later, recovery room,15 minutes, 30 minutes, 45 minutes, 60 minutes later, return to the ward, 4 hours, 8 hours, and12 hours later.Data were analyzed by descriptive and inferntial statistics(SPSS 19.0 for Windows).Frequency distribution, percentage, mean, standard deviation,Chi-square test , samples t-test for paired samples t-test were computed.Respiratory rates while in the surgical waiting area were lower for the music group than for the control group (p = 0.002). There was no significant difference between these groups for blood pressure, heart rate, pain intensity, or opioid dosage. However, a within-group comparison showed that diastolic blood pressure in the music group was significantly and consistently decreased during postoperative recovery.
