Abstract

The purpose of this descriptive study was to investigate the outcomes of postoperative pain management among patients receiving elective surgery in a tertiary hospital of southern, Thailand. The purposive sample consisted of 88 patients who undergone elective surgery. The data were collected using a set of questionnaire including: (1) the Demographic Data and Illness History Sheet, (2) the Post-operative Pain Management Perception Questionnaire, (3) the Postoperative Pain Intensity Assessment, (4) the Impact of Post-operative Pain Questionnaire, and (5) the Post-operative Pain Management Satisfaction Questionnaire. The content validity was verified by 3 experts. The reliability of the Post-operative Pain Management Perception Questionnaire was examined and yielded the Kuder-Richardson-20 of .83. The reliability of the Impact of Post- operative Pain Questionnaire and the Post-operative Pain Management Satisfaction Questionnaire were examined and yielded the Cronbach's alpha coefficient of .92 and 1.00 respectively. The data were analyzed using descriptive statistics, and Spearman Rank Correlation. The results of the study were as follows: 1. The mean score of post-operative pain management perception of the subjects was at a high level (M - 26.14, SD = 2.50). 2. The mean score of pain intensity of the subjects was at a high level (M - 7.59, SD = 2.04) and decreasing to at a moderate level (M = 5.89, SD = 1.91) and at a mild level (M - 3.58, SD = 1.38). 3. On day-l post-operation, the impact of pain was at a high level, particularly the dimensions of daily activity (Mdn - 8.00, IQR - 3.00), sleeping (M - 6.39, SD = 2.71), walking (Mdn - 8.00, IQR - 4.00), mobility (Mdn - 7.00, IQR - 2.00). and anxiety (M- 6.13, SD - 344). On day-2 post-operation, the impact of pain was at a moderate level, particularly the dimensions of daily activity (M - 5.58, SD - 2.45), sleeping (M - 4,66, SD - 2.44), and walking (M = 4.42, IQR = 2.68). On day-3 post-operation, the impact of pain was at a mild level, particularly the dimensions of daily activity (M - 2.71, SD = 2.37) and walking (Mdn = 2.00, IOR = 3.00). 4. The mean score of post-operative pain management satisfaction of the subjects was at a high level (Mdn - 3.00, IQR = 1.00) 5. Correlation analysis showed that there were significantly positive correlation between the post-operative pain management perception and the post-operative pain management satisfaction (r = 25, p < 05), and between the post-operative pain intensity and the impact of post-operative pain (r = 48, p < .01). The research findings showed that the outcomes of post-operative pain management were at a high level based on the perception of the patients. However, the pharmacological pain management should be improved. In case of severe pain, nurse should reassess and notify the physician for increasing the effectiveness of post-operative pain management.
