The purpose of this study was to examine the effects of conscious sedation on pain and anxiety of patients in implant surgery. A total of 95 patients who underwent implant surgery were included in the study. In this study, the patient's anxiety and pain to evaluate the pre-operative Visual Analogue Scale (VAS), during-operative Pain Question (PQ), post-operative (Short-form McGill Pain Questionnaire [SF-MPQ], VAS) was used for tools such as questionnaires. The data were analyzed using the chi-squire, independent-samples t-test, multiple linear regression analysis. As a result, the pain reduction was significantly different between the sedative dental treatment and non-sedative dental treatment (p<0.05). The finding of the study multiple linear regression analysis showed that operation time, implant surgery experience, gender, age, operation form and Pain Catastrophizing Scale (PCS) with factors that affect the pain and anxiety (p<0.05). According to the results of the study, considered to be necessary to develop intervention strategies effective using the PCS when managing pain and anxiety of behavior management of this implant patient. Thus, it is advised to provide necessary practical guidelines and dental utilization behaviors on patients with conscious sedation.

Background: The efficacy of local anesthesia decreases in patients with symptomatic irreversible pulpitis. Therefore, it was proposed that the use of premedication with an anti-inflammatory drug might increase the success rate of pulpal anesthesia in mandibular posterior teeth with vital inflamed pulp. Methods: One hundred thirty-four patients who were actively experiencing pain willingly participated in this study. The Heft Parker (HP) visual analog scale (VAS) was used to record the initial pain intensity. Patients were randomly allocated to receive a placebo, 10 mg of ketorolac, and 650 mg of paracetamol. The standard inferior alveolar nerve block (IANB) was administered to all patients using 2% lidocaine with 1:200,000 adrenaline after one hour of medication. After 15 min, the patient was instructed to rate the discomfort during each step of the treatment procedure, such as access to remaining dentin, access to the pulp chamber, and during canal instrumentation on the HP VAS. IANB was considered successful if the patient reported no or mild pain during access preparation and instrumentation. Moderate or severe pain was classified as a failure of IANB and another method of anesthesia was used before continuing the treatment. Results: The rate of successful anesthesia in the placebo, paracetamol, and ketorolac groups was 29%, 33%, and 43%, respectively, and no statistically significant difference was found between the groups. Conclusion: Preoperative administration of paracetamol or ketorolac did not significantly affect the success rate of IANB in patients with irreversible pulpitis. No significant difference was observed between the paracetamol and ketorolac groups.

Post-thoracotomy pain is so severe that lead to postoperative complications, such as sputum retention, segmental or lobar atelectasis, pneumonia, hypoxia, respiratory failure due to the patient`s inability to cough, deep breathing and movement. Many authors have been trying to reduce the post-thoracotomy pain, but there is no method of complete satisfaction. In 1974, Nelson and associates introduced the intercostal nerve block using the cryoprobe. The application of cold directly to the nerves causes localized destruction of the axons while preserving the endoneurium and connective tissue, thereby introducing a temporary pain block and able to complete regeneration of intercostal nerves. One hundred and two patients, who undergoing axillary or posterolateral thoracotomy at the Department of Thoracic and Cardiovascular Surgery in Korea University Medical Center between April 1990 and August 1990, were evaluated the effects of cryoanalgesia for the post-thoracotomy pain reduction. The patients were divided into two groups: Group A, control, the patients without the cryoanalgesia[No.=50], Group B, trial, the patients with cryoanalgesia[No.=52]. Before the thorax closed, in the group A, local anesthetics, 2% lidocaine 3cc, were injected to the intercostal nerves[one level with the thoracotomy, one cranial and caudal intercostal level and level of drainage tube insertion]. In the group B, cryoprobe was directly applied for 1 minute at the same level. Postoperative analgesic effects were evaluated by the scoring system which made arbitrary by author: The pain score 0 to 4, The limitation of motion score 0 to 3, The analgesics consumption score 0 to 3, The total score, the sum of above score, 0 to 10. For the evaluation of immediate analgesic effects, the score were evaluated at the operative day, the first postoperative day, the second postoperative day, and the seventh postoperative day. The effects of incision type, and rib cut to the post-thoracotomy pain were also evaluated. The results were as follows; 1. The intercostal block with cryoanalgesia reduced the immediate postoperative pain significantly compare with control group. 2. The intercostal block with cryoanalgesia improved the motion of the operation side significantly compare with control group. 3. The intercostal block with cryoanalgesia reduced the analgesics requirements at the immediate postoperative periods significantly. 4. The intercostal block with cryoanalgesia lowered the total score significantly compare with control group. 5. The intercostal block with cryoanalgesia were more effective to the mid-axillary incision than to the posterolateral incision 6. The intercostal block with cryoanalgesia were more effective to the patients without rib cut than to the patients with rib cut. 7. No specific complication need to be treated were not occurred during follow-up.

In this study, we developed novel indicators to assess postoperative pain based on PPG derivative waveform. As the candidate indicator of postoperative pain assessment, the time from the start of beating to the n-th peak($T_n$) and the n-th peak amplitude($A_n$) of the PPG derivative were selected. In order to verify derived indicators, each candidate indicator was derived from the PPG of 78 subjects before and after surgery, and it was confirmed whether significant changes were observed after surgery. Logistic classification was performed with each proposed indicator to calculate the pain classification accuracy, then the classification performance was compared with SPI(Surgical Pleth Index, GE Healthcare, Chicago, US). The results showed that there were significant differences(p < 0.01) in all indicators except for $T_3$ and $A_3$. The coefficient of variation(CV) of every time-related indicators were lower than the CV of SPI(30.43%), however, the CV in amplitude-related parameters were higher than that of SPI. Among the candidate indicators, amplitude of the first peak, $A_1$, showed that highest accuracy in post-operative pain classification, 68.72%, and it is 15.53% higher than SPI.

Background: This purpose of this study is to compare the analgesic efficacy, occurrence of motor block and other side effects of 48 hr continuous postoperative epidural infusions with 0.125% ropivacaine with fentanyl or 0.15% ropivacaine with fentanyl. Methods: Forty patients undergoing Cesarean section were randomly allocated into two groups. Both groups received epidural injection of 2.0% lidocaine 19 ml and 0.75% ropivacaine 2-5 ml with fentanyl $50{\mu}g$ for 20 minutes before surgery. Following surgery, a continuous epidural infusion using a two- day infusor was given for 40 minutes for post-operative pain control. Group 1 (n = 20) then received 0.125% ropivacaine and 6 ug/ml of fentanyl at a rate of 2 ml/h. Group 2 (n = 20) received 0.15% ropivacaine and 6 ug/ml of fentanyl at the same rate. Visual analog scales (VAS) for pain during rest and movement, sensory change and motor blockade were assessed for 48 hr after surgery. Results: There were no significant differences in VAS for pain during rest or movement. The incidence of side effects was similar in both groups. Conclusions: Using 0.125% ropivacaine with fentanyl via an epidural route provided similar pain relief and side effects as 0.15% ropivacaine with fentanyl.

Purpose: The purposes of this pilot study were to describe the perceived effectiveness of music therapy for pain control and to identify music preference for postoperative pain and anxiety control in Korean women who had a gynecological surgery. Sample: A convenience sample of 52 women was recruited from a gynecological unit at P University hospital and they were interviewed to assess their perception of music therapy and music preference using a structured study questionnaire. Results: Fifty-six percent of women reported that music therapy would be effective and 96% perceived it would be effective if combined with analgesics. The best music chosen for relieving postoperative pain and anxiety were Korean old pop and ballad song/music followed by Korean religious music, American pop songs, piano music, Korean classic songs, and Orchestra music. Conclusion: There was a cultural difference in music preference for the relief of post-operative pain in this sample. Therefore, effects of music for postoperative pain control need to be determined after considering musical preferences of postoperative women in Korea.

Purpose: In previous study, the frequency of osteoarthritis and discomfort were high in ankle fracture-dislocation but detail results about ankle fracture-dislocation has rarely been investigated. In this study, we retrospectively analyze the outcome of the operative treatment of ankle fracture with dislocation for over-2 years follow up. Materials and Methods: There were 47 cases of ankle fracture-dislocation in our hospital from March 2007 to May 2010. We investigated 20 patients who underwent operation and were possible for over-2 years follow up. The result was estimated with the direction of dislocation, fracture type, the time of bone union and post-traumatic osteoarthritis with plain radiologic images. In clinical assessment, we statistically evaluated the function and pain through AOFAS score and Olerud & Molander scoring system. Results: By Lauge-Hansen classification, there were 13 cases(65%) of pronation-external rotation and 6 cases(30%) of supination-external rotation, 1 case(5%) of supination-adduction. AOFAS score was 85.5, and Olerud & Molander score was "excellent" in 8 cases, "good" in 5 cases, "fair" in 3 cases and "poor" in 4 cases. Postoperative complications in 4 cases revealed post-traumatic arthritis. All kinds of lateral dislocation of ankle fracture was 15 cases and the most common. Of these, all 3 cases, anterolateral dislocation showed post-traumatic osteoarthritis. Conclusion: In ankle fracture-dislocation, post-traumatic osteoarthritis occurred in 4 of 20 patient(20%). Especially, the possibility of post-traumatic osteoarthritis was more in cases of anterolateral or lateral dislocation. So, it must be needed that deliberate examination, for example, preoperative MRI and sufficient explanation to patient. Also, we have to follow up the patients carefully.

Purpose: The purpose of this study was to examine the effect of pre-warming on body temperature, anxiety, pain, and thermal comfort. Methods: Forty patients who were scheduled for abdominal surgery were recruited as study participants and were assigned to the experimental or control group. For the experimental group, a forced air warmer was applied for 45-90 min (M=68.25, SD=15.50) before surgery. Body temperature and anxiety were measured before and after the experiment, but pain and thermal comfort were assessed only after the surgery. Hypotheses were tested using t-test and repeated measured ANOVA. Results: The experimental group showed higher body temperature than the control group from right before induction to two hours after surgery. Post-operative anxiety and pain in the experimental group were less than those of the control group. In addition, the score of thermal comfort was significantly higher in the experiment group. Conclusion: Pre-warming is effective in maintaining body temperature, lowering sensitivity to pain and anxiety, and promoting thermal comfort. Therefore, pre-warming can be recommended as a preoperative nursing intervention.
