Purpose: This study was to develop a post-operative exercise program, apply it to patients undergone lumbar spinal fusion surgery, and evaluate the effectiveness of the program on pain and disability activities of daily living. Methods: Fifty six patients who had lumbar spinal fusion were enrolled in this study. The patients were divided into two groups; 28 patients in the intervention group completed post-operative lumbar exercise program including walking for four weeks and 28 patients in the control group only did walking exercises. The degrees of pain on low back and leg were evaluated using visual analog scale (VAS) and the functional outcome was evaluated using the Korean version of Oswestry Disability Index (KODI) before surgery and 5 weeks after surgery. The data were analyzed using descriptive statistics, Chi-square test, t-test with SPSS 18.0 program. Results: Low back and leg pain of the participants in both experimental and control groups were improved after surgery compared to pre-surgery pain. However, there was no statistically significant difference between the groups. KODI score in the intervention group was significantly lower than that of the control group (p=.014). Conclusion: The developed post-operative exercise program in patients with lumbar spinal fusion surgery seems to be a useful intervention to reduce disability in activities of daily living.

Purpose: The purpose of this study was to examine the effect of three kinds of modes using bolus button of PCA on level of pain and side effects of analgesic and amount of drug consumption in post-operative patients according to whether the medication is controlled by the patient, the caregiver or the nurse. Method: The participants were 684 patients using PCA after an operation. The data collection period was from March 19 to April 6, 2007. Results: It was found that there were statistical differences in gender, age, type of surgery, pain on first post-operative day, amount of drug consumption, nausea, and vomiting. The ratio for patient controlled medication was 55.7% for women, and 70.5% for men, and for care-giver controlled medication, 35.1% for women, and 20.0% for men. Average pain scores for the first post-operative day were $3.9{\pm}2.2$ for patient controlled medication and $4.5{\pm}2.3$ for care-giver controlled medication. There were statistical differences according to mode used for PCA for amount of drug consumptions, nausea and vomiting but not for pain, operation day or pruritus. Conclusion: This study was carried out to examine risks according to who controls the PCA for post-operative patients. The results can help to develop education program for everyone who is involved in PCA, patients, caregivers, nurses and doctors.

Purpose: The purpose of this study was to ascertain the effects of preoperative information on postoperative state anxiety, plasma cortisol, and pain for patients under total knee arthroplasty, and to provide generic data with nursing intervention for total knee arthroplasty. Methods: Data were collected from 34 patients who had total knee arthroplasty from January 3, 2003 to January 15, 2004. An experiment group of 17 patients was provided with pre-operative information prepared by the researchers; a control group of another 17 patients was provided with general information. Data were analyzed through Chi-squared test, t-test, paired t-test and ANCOVA using SPSS WIN 11.0. Results: There was no significant differences between the experiment group and the control group in post operative state anxiety(p=.612). However, there was statistically a significant difference between the above two groups in post operative plasma cortisol(p=.012). There was a statistically significant difference between the above two groups in post operative pain(p=.041). Conclusion: According to the results of the study, the authors concluded that the preoperative information for patients under total knee arthroplasty had the effect on the decrease of postoperative plasma cortisol and pain.

Purpose: The purpose of this study was to test whether pre-operative visual information and parental presence had positive effects on anxiety, delirium, and pain in pediatric patients who awoke from general anesthesia in a post-surgical stage. Methods: This study used a non equivalent control-group post test design (n=76). Independent variables were provision of pre-operative visual information and parental presence for post-surgical pediatric patients in PACU (post anesthesia care unit). Dependent variables were anxiety, delirium, and pain in the pediatric patients measured three times at 10 minute intervals after extubation in the PACU. Measurements included Numerical Rating Scale for assessing state anxiety, Pediatric Anesthesia Emergence Delirium Scale by Sikich & Lerman (2004) for delirium, and Objective Pain Scale by Broadman, Rice & Hannallah (1988) for pain. Results: Experimental group showed significantly decreased state anxiety at time points-10, 20, and 30 minutes after extubation. Delirium was significantly lower at 10 minutes and 30 minutes after extubation in the experimental group. Pain was significantly lower at 10 minutes after extubation in the experimental group. Conclusion: The results of this study suggest that this intervention can be a safe pre-operative nursing intervention for post-surgical pediatric patients at PACU.

Many clinical and laboratory experiments have been developed to prevent or decrease post-operative pain. One of these methods is pre-operative administration of opioid. Recently there have been differing and debatable results reported of pre-operative treatment for post-operative pain management. It was our study to determine whether pre-operative epidural fentanyl prevented central facilitation or wind up of spinal cord from nociceptive afferent input through c-fibers. We evaluated the effect of epidural fentanyl 50 mcg 10 minutes before operation and 10 minutes before the end of surgery. 28 parturient women for Cesarean Section were randomly allocated to receive the epidural fentanyl either at 10 minutes before operation (Group 1, n=14) or 10 minutes before the end of surgery (Group 2, n=14). All of the 28 parturient women were anesthetized with epidural block using (22 ml of) 2% lidocaine supplemented with light general anesthesia ($N_2O$ 2 L/min-$O_2$, 2 L/min), we controlled post-operative pain with epidural PCA(patient controlled analgesia) infusion of meperidine and 0.07% bupivacaine. The action duration of epidural fentanyl from the end of surgery to the first requirement of analgesics with epidural PCA were not significantly different between the two groups. No significant differences between two groups were observed in VAS pain score at 1, 2, 3, 6, 12, 24, and 48 hours after the operation. The number of self administration of narcotics with PCA during 48 hours after surgery were the same between the two groups. The hourly infusion rates of demerol were the same. Pre-operative administration of fentanyl was not clinically effective compared to administration just before the end of surgery for postoperative pain control.

Objective : The goal of this study was to establish the benefit and prognostic factors of lumbar medial branch block[MBB] for low back pain. Methods : A retrospective analysis was based on the data obtained from 281 patients with low back pain, who visited our hospital between January 2001 and November 2004. Pain relief was evaluated at 2 weeks, 1 month and 3 months. The authors analyzed the results of MBB according to the patient's age, sex, symptom duration, pathologic condition, and presence of radiating pain. Results : Two hundred eighty one patients had sprain [151]. lumbar fracture [27], spinal stenosis [50], herniated lumbar disc [24] acute post-operative pain [8], and chronic post-operative pain [21] with success rate of 63.6%, 59.3%, 26.0%, 25.0%, 87.5% and 42.9%, respectively. The effects of MBB in sprain, lumbar fracture, and acute post-operative pain were significantly better than those in stenosis, herniated lumbar disc and chronic post-operative pain patients. The patients in young age group [<60 years], with short symptom duration [<6 months] and without radiating pain showed good response to lumbar MBB. Conclusion : The lumbar MBB appears to be safe and effective for low back pain in certain selected patients. Good prognostic factors were low back pain without surgical conditions and radiating pain, with short symptom duration [<6 months], and in relatively young age [<60 years] group.

Purpose: To examine knowledge and attitudes of nurses on post-operative pain, and to find the factors that hinder pain management by the nurses. Method: Data was collected using a questionnaire from all the nurses working in the surgical units and intensive care units in a hospital in Seoul between March 12 and 22, 2007. Data was analyzed with descriptive statistics, t-test, $x^2$ test, and Pearson Coefficient Correlation. Result: The average knowledge score on pain was $9.33{\pm}1.55$, and that for analgesics was $6.89{\pm}2.00$. There was a significant difference in knowledge of analgesics in terms of career(p=0.012), present work place(p=0.024) and education(p=0.042). The knowledge on pain etiology was significantly different in career. Around 61.1% of respondents answered that they would administer analgesics immediately if patients complaint pain, and 94.1% re-administer analgesics if the VAS score is over 5.69.3% thought that their knowledge was adequate for pain management. The attitudes of pain management were significantly different in career. Conclusion: We found that a further improvement on nurses' knowledge on pain management and analgesics is necessary. This study also suggests a need for professional education for nurses on post-operative pain management.

Purpose: The purpose of this study is to identify main factors affecting patients' uncertainty following lumbar spinal surgery. Methods: A survey was conducted of a sample 155 post -operative patients in April to June 2010. Uncertainty and knowledge about self-care after spinal surgery and the back pain evaluation were measured. Data were analyzed with t-test, ANOVA, Pearson correlation, and multiple regressions. Results: The mean score of uncertainty level was $27.66{\pm}6.32$. Levels of uncertainty were different by age, gender, educational level, pain duration, and number of types of pain. Uncertainty was positively correlated with knowledge of post-op self-care, back pain, and mental health. The results of multiple regression indicated that knowledge of post-op self-care and mental health were significant predictors with 35.1% of the variance in uncertainty. Conclusion: A program including post-operative self-care education and mental health promotion is required to reduce uncertainty of patients with lumbar spinal surgery.

Background: Every patient who undergoes mandibular third molar surgery is concerned about post-operative pain. Indeed, previous researchers have used various methods to treat such pain. This study aimed to assess the effectiveness of sublingual injection of dexamethasone (8 mg) to treat post-operative pain after mandibular third molar surgery. Method: This was a randomized, double-blind, split-mouth, clinical trial, involving 48 healthy patients who required surgical removal of two mandibular third molars with similar bilateral positions. All operations were performed by the same experienced surgeon. The patients were randomized into a study group (8 mg dexamethasone injection) and a placebo group (normal saline injection). Both interventions were injected into the sublingual space immediately after local anesthesia, 30 min before the first incision. The study group received an 8 mg dexamethasone injection, while the placebo group received a normal saline injection. The wash period between the patients' two operations was 3 to 4 weeks. Pain was assessed by recording the number of analgesic tablets (rescue drug) consumed, as well as by noting the patients' responses to the visual analog scale (VAS) on the first, second, and third days after surgery. Results: The study group differed significantly from the placebo group in terms of VAS score and analgesic consumption. Conclusion: Dexamethasone (8 mg), injected sublingually, significantly eased post-operative pain after surgical removal of the mandibular third molar.

Purpose: The purposes of this study were to identify and compare various types of post operative pain management and the costs for pain management following 4 different types of surgery. Methods: Data were collected from 325 medical charts which were extracted from the billing databases of a tertiary hospital and analyzed using numbers, percentages, one way ANOVA, and Scheff$\acute{e}$ test. Results: For pain management, 10.5% of patients used PCA only, but the other patients combined other methods with PCA. The average length of PCA use was significantly different by operation. Almost one third (32.9%) of patients experienced at least one of side effects due to analgesics used for pain management, with highest incidence being for nausea and vomiting. For patients who underwent a total abdominal hysterectomy, 34.7% used PCA less than 2 days due to side effects of the analgesics and the ratio of analgesia cost to total hospital cost and total pharmacy cost were highest compared to other operations. Conclusion: The results of this study indicate a need to develop new strategies to more effectively manage postoperative pain to decrease incidences of side effects without increasing medical costs.
