Purpose: The purpose of this study was to identify the nursing needs of elderly patients who got a surgical operation under regional anesthesia(spinal, epidural, nerve block). Methods: The participants were 126 elderly patients who completed a questionnaire. The data were collected October 1 and October 31, 2012, and analyzed using descriptive statistics, t-test and ANOVA, $Scheff{\acute{e}}$ test. Results: The mean score for the nursing needs of elderly patients administered regional anesthesia during surgery was $3.08{\pm}0.38$, The scores for specific nursing needs were as follows: educational needs ($3.47{\pm}0.50$), spiritual needs ($3.37{\pm}0.78$), physical needs ($3.31{\pm}0.46$), emotional needs ($2.72{\pm}0.50$), and environmental needs ($2.51{\pm}0.47$). There were significant differences in nursing needs relative to gender, religion, and spouse status. Additionally, there were significant differences in nursing needs according to surgery department, the length of time the surgery, and the ASA(American Society of Anesthesiologists) physical classification. of the operation-related characteristics. Conclusion: When caring for elderly patients during the surgery, nurses must provide adequate information about the surgery and anesthesia. Further studies are needed to develop and evaluate nursing interventions to provide quality surgical care for the elderly patients.

Background: Video-Assisted Thoracic Surgery can be performed with the lung collapsed. During the procedure, pleural adhesion may result in lung injury, bleeding, and thoracotomy conversion. Identifying the presence of pleural adhesion before surgery can make it easy to plan trocar introduction and perform the procedure. Material and Method: Between June 2009 and November 2009, we performed ultrasound in 24 patients to detect pleural adhesion before surgery and compared the results with the operative findings. We primarily examined the lateral chest, where the trocar would be inserted, and, occasionally, the anterior or posterior chest. Result: Patient diseases were: 6 hyperhidroses, 8 interstitial lung diseases, 5 lung cancers, 2 mediastinal tumors, 1 peripheral pulmonary embolism, 1 metastatic lung cancer, and 1 sarcoidosis. Of the 22 patients who did not have pleural adhesions on ultrasound, four revealed mild adhesions not related to the trocar insertion sites. However, ultrasound showed pleural adhesions in two patients, consistent with the operative findings. There was no air leak or thoracotomy conversion related with trocar insertion. Conclusion: Ultrasound requires only a few minutes to detect the presence of the pleural adhesion and was very useful in identifying the pleural adhesion before VATS.

Background: It has been known that internal thoracic artery grafting has a better patency rate compare to other graft conduits in coronary revascularization. Better patency rates can be expected in more coronary arteries with the use of bilateral internal thoracic artery. However, there were some debates on the complications after the use of bilateral internal thoracic artery. The purpose of our study was to reveal the results of bilateral internal thoracic artery. Material and Method: The 26 coronary artery bypass operations with bilateral internal thoracic artery were performed from July 2001 to May 2002. We compared the results of 8 diabetic patients to those of 18 non-diabetic patients. We compared the results of BITA (bilateral internal thoracic artery) group to those of SITA (single internal thoracic artery) group that were 20 patients and performed during same period. Result: There was no mortality. There was one wound complication in the diabetic group and one in the non-diabetic group. There were no significant differences in operation time, duration of mechanical ventilation, amount of bleeding, infusing duration of cardiotonics, and complication between two groups. There were no significant differences in results between the BITA group and the SITA group. Conclusion: There were no significant differences in early results between the BITA group and the SITA group, and there were no significant differences in results between the diabetic group and the non-diabetic group. We think coronary artery bypass grafting with the use of bilateral internal thoracic artery is considered in diabetic patients.

Background: The incidence of cervical esophageal cancer is low compared with that of thoracic esophageal cancer, and the role of surgery for cervical esophageal cancer is limited compared with that of radiotherapy or chemotherapy. This study was carried out to determine the outcome of surgery for cervical esophageal cancer. Material and Method: We analyzed retrospectively medical records of 43 patients who had undergone curative surgical resection for cervical esophageal cancer from January 1989 to December 2002. Follow-up loss was absent and the last follow-up was carried out in February 28, 2004. Result: The mean age was 60 years old and the male to female ratio was 40:3. Histologic types were squamous cell carcinoma 42 patients and malignant melanoma 1 patient. The methods used for esophageal reconstruction were gastric pull-up 32 patients, free jejunal graft 7 patients and colon interposition 4 patients. Postoperative complications occurred in 31 patients (72%), and operative mortality occurred in 7 patients (16%). Pathologic stages were I 3, IIa 14, IIb 1, III 19, and IVa 6 patients. Tumor recurrence occurred in 16 patients (44%), and the 3 and 5-year survival rates were 29.3% and 20.9%. Conclusion: The reported surgical results for cervical esophageal cancer showed somewhat high operative mortality, postoperative complication rates and recurrence rates and a low long-term survival rate. It is suggested that multimodality treatment including surgery is needed for the treatment of cervical esophageal cancer because radiotherapy or chemotherapy without surgery could not relieve dysphagia or resolve the tumor completely.

From March, 1983 to June, 1994, twenty-two patients underwent coronary artery and combined operations. The ages of the patients ranged from 42 years to 72 years (mean 60.4$\pm$8.2 years). There were 17 male and 5 female patients. The left ventricular (LV) ejection fraction ranged from 25% to 65% (mean 46.9$\pm$14.2%). Nine patients had mechanical complication of myocardial infarction (MI), of which 5 were LV aneurysm, 3 ventricular septal defect and 1 mitral regurgitation. Nine patients had rheumatic valvular heart disease of whom 7 with aortic valve disease and 2 with mitral valve disease. Two other patients had left atrial thrombi, only one with atrial septal defect a d another with aneurysm of ascending aorta. An average of 2.1$\pm$1.0 bypasses was done, ranging from one to four. There were 3 postoperative complications; 2 perioperative MI and 1 leg wound infection. Among complicated patients, mortality was 1 patient (4.5%) due to low cardiac output syndrome after perioperative MI. With 3 to 136 months follow-up (mean 41.1$\pm$40.2 months), late mortality was 1 patient due to cerebral vascular accident. Among long-term survivors, all patients are in New York Heart Association functional class I or II. Although the number of patients was small, our surgical results were favorable. Therefore we think that coronary revascularization combined with heart operation does not increase the operative risk when associated coronary artery disease is present, and it reduces the occurrence of late death.

Background: Bupivacaine with fentanyl might be suitable as the spinal anesthesia for performing ambulatory surgery to treat varicose vein. Material and Method: Thirty patients who underwent spinal anesthesia for a varicose vein operation were enrolled in this study. They were classified into 2 groups of either fentanyl 25ug mixed with bupivacaine 4mg (group FB4) or bupivacaine 8mg (group B8). We compared the groups for the success of the analgesia, the recovery time from sensory and motor block, the side effects and the postoperative complications. Result: The groups did not differ significantly regarding the success of analgesia (13 of 15 [group FB4], 15 of 15 [group B8]). None of the patients were converted to general anesthesia due to surgical pain. None of the patients required medication for hypotension and/or bradycardia. The operative and nonoperative side effects of motor block (tested for by using a modified Bromage scale) was significantly lower in group FB4 than that in group B8, as checked at 2 hours after spinal anesthesia (p<0.05). Recovery from spinal block was significantly quicker in group FB4 than that in group B8 (p<0.05). The first voluntary micturition time did not differ significantly (6.5 hours v 4.5 hours [p=0.143]) between the groups, but a nelatone catheter was inserted into 2 of the group B8 patients due to dysuria. Conclusion: Adequate intraoperative analgesia and hemodynamic stability and faster mobilization were achieved using bupivacaine 4mg with fentanyl 25ug. Low dose spinal anesthesia with fentanyl is suitable for performing ambulatory surgery to treat varicose vein.

Pulmonary atresia with intact ventricular septum has continued to have a high surgical mortality and morbidity. This mAy attribute to the non-uniformity of the anomaly. We reviewed a total of 34 infants with pulmonary atresla and intact ventricular septum managed in this hospital between 1987 and 1995. Mean age and body weight were 57.2 (range, 3-208) days and 4.1 (range, B.3∼6.8) kg. The preoperative Z-value of the diameter of the tricuspid valve was less than -2 in 85.2% of patients and less than -4 in 33. 3% . It is well correlated w th right ventricular cavity size (n=27. r10.68, p< 0.05). Coronary artery-right ventricular fistulas were identified in 3 patients, and right ventricular dependency was suspected in 1 Over All hospital mortality was 23.5%(8/34), although it decreased to 16.6%(4124) in 1990s. Subsequent procedures were performed in 6 patients between 3 days and 58 months after Initial palliation : one bidirectional cavopulmonary shunt and 1 Fontan operation after systemic-pulmonary shunt, 3 transannular patch + atrial septal defect closure and 1 additional systemic-pulmonary shunt after polmonary valvectomy or valvotomy. Changes of Z-values of the diameter of tricuspid valve have been followed up in 11 patients between 1 and 66 months postoperatively. Z-values were increased In 5 out of 8 transannular right ventriculAr outflow tract enlargement group and in 1 out of 3 pulmonary valvectomy or valvotomy group. Our data suggest that tailoring a treatment to right ventricular cavity size and coronary anom lies may improve the surgical outcome. A Z-value of the tricuspid valve diameter could be used.

Purpose: Laparoscopic surgery for gastric cancer was introduced in the past decade because it was considered less invasive than open surgery, and this results in less postoperative pain, faster recovery and an improved quality of life. Several studies have demonstrated the safety and feasibility of this procedure. We examined the outcome of performing laparoscopic surgery for gastric cancer over the last two year. Materials and Methods: From April 2004 to December 2006, 329 patients with gastric adenocarcinoma underwent a laparoscopy-assisted distal gastrectomy with lymph node dissection. The data was retrospectively reviewed in terms of the clinicopathologic findings, the perioperative outcomes and the complications. Results: The total patient group was comprised 196 men (59.6%) and 133 women (40.4%). The mean BMI was 23.6 and the mean tumor size was 2.7 cm. The mean number of harvested lymph node was 22.7, and this was 18.6 before 30 cases and 23.1 after 30 cases, and the difference was significant (P=0.02). The mean operation time was 180.9 min, and this was than 287.9 min before 30 cases and 170.2 min after 30 cases. After 30 cases, there was a significant improvement of the operation time (P<0.01). The mean incision length after 30 cases was shorter than that before 30 cases (P<0.01). Postoperative complications occurred in 24 (7.3%) of 329 patients and there was no conversion to open surgery. Conclusion: Even though the LADG was accompanied by a difficult learning curve, we successfully performed 329 LADG procedures over the past 2 years and we believe that LADG is a safe, feasible operation for treating most early gastric cancers (EGC).

Background: As the early outcome after coronary artery bypass grafting(CABG) has been stabilized, neurologic complication has now become one of the most important morbidity. The aim of this study was to find out the risk factors associated with the neurologic complications after CABG. Material and Method: In 351 patients who underwent CABG, the incidence and features of neurologic complications, with associated perioperative risk factors, were retrospectively reviewed. Neurologic complication was defined as a new cerebral infarction confirmed by postoperative neurologic examination and radiologic studies, or delayed recovery of consciousness and orientation for more than 24 hours after the operation. Result: Neurologic complications occurred in 18 patients(5.1%), of these nine(2.6%) were diagnosed as having new cerebral infarctions(stroke). Stroke was manifested as motor paralysis in four patients, mental retardation or orientation abnormality in four, and brain death in one. Statistical analysis revealed the following variables as significant risk factors for neurologic complications by both univariate and multivariate analyses: cardiopulmonary bypass longer than 180 minutes, atheroma of the ascending aorta, carotid artery stenosis detected by Duplex sonography, and past history of cerebrovascular accident or transient ischemic attack. Age over 65 years, aortic calcification detected by simple X-ray, and intraoperative myocardial infarction were significant risk factors by univariate analysis only. Neither the severity of carotid artery stenosis nor technical modifications such as cannulation of the aortic arch or single clamp technique, which were expected to affect the inciden e of neurologic complications, had significant relationship with the incidence. Conclusion: This study confirmed the strong association between neurologic complications after CABG and atherosclerosis of the arterial system. Therefore, to minimize the incidence of neurologic complications, systematic evaluation focused on atherosclerotic lesions of the arterial system followed by adequate alteration of operative strategy is needed.
