Purpose: The purpose of this study was to evaluate the effects of preoperative PCA (Patient-Controlled Analgesia) education on pain, patient attitude, and patient satisfaction in surgical patients. Methods: The study was a quasi-experimental research design. The participants were 54 patients who were admitted for surgery at I hospital in G city, Korea. Of the 54 patients, 26 were assigned to the experimental group and the rest to the control group. The PCA education was provided in the nurses' station, individually to patients in the experimental group the day before their operation. Multimedia and brochure, and a real PCA model were used. The control group received only verbal education about PCA. Results: The postoperative pain scores were significantly different for lapse of time in the experimental group compare to the control group. Patient attitude toward using pain medicine was significantly more positive in the experimental group than in the control group. The postoperative patient satisfaction with pain management was significantly higher in the experimental group than in the control group. Conclusion: The study findings indicate that preoperative PCA education could be an effective nursing intervention for pain management of surgical patients.

Cardiopulmonary bypass (CPB) for cardiac surgery induces the production and release of numerous chemotactic substances and cytokines, ensuing systemic inflammatory response that causes postoperative major organ dysfunctions. We performed a randomized, prospective study to investigate clinical effects of preoperative treated-methylprednisolone for preventing inflammation in pediatric cardiac surgery with CPB. Thirty pediatric patients scheduled for elective cardiac surgery were randomized to either control(n=15) or steroid group (n=15, 10 mg/kg of methylprednisolone). Arterial blood samples were taken before and after the operations for measuring total leukocyte (T-WBC) and differential counts, platelet counts, interleukin-6 (IL-6), myeloperoxidase (MPO), neuron specific enolase (NSE), troponin-I (TNI), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine levels. Postoperative parameters such as pulmonary index (PI, $PaO_2/FiO_2$), 24 hrs and total bleeding volumes, mechanical ventilating (MVP) and intensive care unit (ICU)-staying periods, and hospitalization were assessed. T-WBC, neutrophil fraction, IL-6, MPO, NSE, TNI, AST and creatinine levels, bleeding volumes, PI, and MVP at the postoperative periods were lower or shorter in steroid group than in control group (P<0.05). These findings indicated that preoperative administration of methylprednisolone attenuated CPB-induced inflammatory reactions, contributing to postoperative recovery of patients underwent cardiac surgery.

Purpose: The study was done to analyze the effects of aroma inhalation method on preoperative anxiety of abdominal surgical patients. Methods: The research design was a nonequivalent control group non-synchronized design. The data were collected from July 25 to October 21, 2005 at C Medical Center in Seoul. The patients were divided into two group of 24 subjects each. In order for measuring the all patient's anxiety before operation and aroma inhalation, Spidlberger(1975) trait anxiety, VAS(visual analogue scale) state anxiety, blood pressure, pulse rate were taken. After experimental group was taken aroma inhalation, VAS state anxiety, blood pressure, pulse rate were measured for two group. Results: After aroma inhalation, VAS state anxiety level, systolic blood pressure, diastolic blood pressure, pulse rate of the experimental group were decreased significantly than those of control group(p = .000, p = .000, p = .030. p = .000). Conclusion: The aroma inhalation method can be considered an effective nursing intervention that relieves the preoperative anxiety of abdominal surgical patients and stabilizes vital signs.

Our aim was to test the hypothesis that preoperative serum levels of matrix metalloproteinase-7 (MMP-7) and -9 (MMP-9) and tissue inhibitor of matrix metalloproteinase (TIMP-1) levels correlate with pathological features. Serum levels of MMP-7, and MMP-9 and TIMP-1 were determined in 90 bladder cancer patients and 40 healthy controls using an enzyme linked immunosorbent assay. Preoperative serum MMP-7 and MMP-9 levels were significantly higher in cancer patients than control groups (p<0.001). In contast, serum TIMP-1 levels were lower (p<0.001). Alteration in MMP-7, and MMP-9, and TIMP-1 production may contribute to tumor angiogenesis and be associated with clinic-pathological features.

Purpose: To study prognostic factors of unilateral calcaneus fracture underwent surgery. Materials and Methods: We selected appropriate 60 cases of 236 calcaneus fracture cases between March 1985 and March 2004, and analyzed the correlation between sex, age, smoking, injury mechanism, Essex-Lopresti classification of calcaneus fracture, preoperative Bohler angle, postoperative Bohler angle, postoperative 1 year Bohler angle and Visual Analogue Scale (VAS), P.S. Kerr's Calcaneal Fracture Score (CFSS). The average age was 41.4 and average follow up period was 74 (12 to 240) months. Results: For follow up period, average VAS is 3.43 and CFSS is 81.23. The sex, age, smoking, injury mechanism, and preoperative, postoperative, postoperative 1 year Bohler angle had no correlation with the prognosis. But the Essex-Lopresti classification of calcaneus fracture, tongue type had better prognosis than joint depression type (VAS : p=0.041, CFSS : p=0.021). Conclusion: In unilateral calcaneus fracture, the sex, age, smoking, injury mechanism, preoperative Bohler angle, postoperative Bohler angle, postoperative 1 year Bohler angle had no correlation with the prognosis of fracture, but in Essex-Lopresti classification, the tongue type fracture had better prognosis than the joint depression type.

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure. In general, a systolic blood pressure goal of <150 mm Hg and a diastolic blood pressure goal of >65 mm Hg are recommended. This article discusses the causes of increased blood pressure and the treatment methods for perioperative hypertension during the preoperative, intraoperative, and postoperative periods, in order to find ways to maintain normal blood pressure in patients during surgery. Further, in this paper, we review the causes of perioperative hypertension, such as anxiety, epinephrine, pain, and postoperative nausea and vomiting. The treatment methods for perioperative hypertension are analyzed according to the following 3 operative periods, with a review of the characteristics and interactions of each drug: preoperative antihypertensive medicine (atenolol, clonidine, and nifedipine), intraoperative intravenous (IV) hypnotics (propofol, midazolam, ketamine, and dexmedetomidine), and postoperative antiemetic medicine (metoclopramide and ondansetron). This article focuses on the knowledge necessary to safely apply local anesthesia with IV hypnotics during facelift surgery without the assistance of an anesthesiologist.

In plastic and reconstructive craniomaxillofacial surgery, careful preoperative planning is essential to get a successful outcome. Many craniomaxillofacial surgeons have used imaging modalities like conventional radiographs, computed tomography(CT) and magnetic resonance imaging(MRI) for supporting the planning process. But, there are a lot of limitations in the comprehension of the surgical anatomy with these modalities. Medical models made with rapid prototyping (RP) technique represent a new approach for preoperative planning and simulation surgery. With rapid prototyping models, surgical procedures can be simulated and performed interactively so that surgeon can get a realistic impression of complex structures before surgical intervention. The great advantage of rapid prototyping technique is the precise reproduction of objects from a 3-dimensional reconstruction image as a physical model. Craniomaxillofacial surgeon can establish treatment strategy through preoperative simulation surgery and predict the postoperative result.

From January, 1982, to December, 1990, 15 patients underwent pericardiectomy for chronic constrictive pericarditis on Department Of Thoracic and Cardiovascular Surgery, School of Medicine, Pusan National University. There were 9 male and 6 female patients [male to female ratio was 1.5: 1] ranging from 15 years to 63 years old [mean age 35.0]. All patients underwent pericardiectomy through a median sternotomy, partial cardiopulmonary bypass was performed on two patients. There were 3 postoperative death [20%]. Six cases [40%] were tuberculous origin 5 cases [34%] were Idiopathic [nonspecific chronic inflammatory change was considered to idiopathic], 2 cases [13%] were malignant origin, 2 cases [13Yo] were pyogenic origin. Dyspnea on exertion was evident in all patients and abdominal distention, general weakness, palpitation, peripheral edema were found. Eleven patients showed low voltage of QRS wave, 7 patients showed diffuse ST-T wave change, 2 patients showed atrial fibrillation on EKG. There were 6 patient showed pericardial thickening, 5 patients showed evidence of restriction, 5 patients showed pericardial effusion, 4 patients showed low cardiac output on preoperative echocardiogram. Hemodynamic response to pericardiectomy were observed; preoperative CVP 26.8 cmH2O declined to 15.0 cmH2O. Preoperative NYHA Functional class showed class II - 1, class III - 10, class IV - 4, postoperative NYHA functional class showed class I - 7, class II - 4, class Ill - l.

Purpose: This study was carried out to investigate the effect of a decrease in indwelling catheter size and preoperative education on bladder discomfort and nursing needs. The study was conducted on patients in the recovery room after their surgery. Methods: This study is a randomized control trial. Data were collected from September 2011 to February 2012 at a university hospital in Bundang, Korea. The sample consisted of 75 patients, excluding one patient from the experimental group 2. From among the patients that were sent to the ICU, 24 were in experimental group 1, 24 were in experimental group 2, and 27 were in the control group. Data were collected and analyzed using a chi-square test, t-test, and one-way ANOVA. Results: There were significant differences between the bladder discomfort experienced by patients in experimental group 1 and the control group, and experimental group 2 and the control group. Then nursing needs of the control group were higher than those of the experimental groups 1 and 2. Conclusion: The decrease in indwelling catheter size and preoperative nursing education is an effective nursing intervention in perioperative care.

Purpose: This study was done to evaluate the usefulness of preoperative computed tomography (CT) and intraoperative laparoscopic ultrasound to facilitate treatment of gastric submucosal tumors. Materials and Methods: The feasibility of laparoscopic wedge resection as determined by CT findings of tumor size, location, and growth pattern was correlated with surgical findings in 89 consecutive operations. The role of laparoscopic ultrasound for tumor localization was analyzed. Results: Twenty-three patients were considered unsuitable for laparoscopic wedge resection because of large tumor size (N=13) or involvement of the gastroesophageal junction (N=9) or pyloric channel (N=1). Laparoscopic wedge resection was not attempted in 11 of these patients because of large tumor size. Laparoscopic wedge resection was successfully performed in 65 of 66 (98.5%) patients considered suitable for this procedure. Incorrect interpretation of preoperative CT resulted in a change of surgery type in seven patients (7.9%): incorrect CT diagnosis on gastroesophageal junction involvement (N=6) and on growth pattern (N=1). In 18 patients without an exophytic growth pattern, laparoscopic ultrasound was necessary and successfully localized all lesions. Conclusions: Preoperative CT and laparoscopic ultrasound are useful for surgical planning and tumor localization in laparoscopic wedge resection.
