Epidural nerve block is the most widely practiced procedure in the pain clinic. Accidental dural puncture during epidural nerve block also has been associated with postdural puncture headache and total spinal anesthesia. Especially, total spinal anesthesia is the most serious complication of epidural nerve block and can lead to a life threatening conditions. We have experienced two cases in whom total spinal anesthesia occurred during epidural nerve block for neck and lower back pain control. Immediately after epidural nerve block, the patients became unresponsive and apneic with loss of muscle tone in all extremity. We performed resuscitations and about 3 hours later the patients recovered completely without any complication.

BACKGROUND: There were several studies for the incidence of gastroesophageal reflux associated with the laryngeal mask airway(LMA), but the results of those studies were much different much different from one another. The aim of this study was to compare the incidence of gastroesophageal reflux and regurgitation of gastric contents between the LMA and the endotracheal tube(ETT). METHOD: Ninety patients scheduled for elective orthopedic surgery with a standardized general anesthetic technique were randomly allocated to receive either a LMA(n-49) or a ETT(n=41) for airway management. The esophageal manometry was carried out for the exclusion of esophageal motility disorders and the 24-hour ambulatory pH metry was done from one day before the operation. A methylene blue(50mg) capsule was swallowed just before the induction and the simultaneous recordings of pH were maintained during anesthesia. At the end of anesthesia, the episodes of regurgitation of gastric contents above hypopharynx were analyzed by the pharyngeal blue staining and the pH metric data were analyzed for the detection of gastroesophageal relux episodes during anesthesia. RESULTS: There was no significant difference in the incidence of gastroesophageal relux(pH< or =4) between two groups; only two patients in LMA and three patients in ETT had reflux episodes during the removal or arousal phase. There was no episode of the pharyngeal blue staining in both group. All of the gastroesophageal reflux patients in both group developed a cough or straining during those phases. There was no clinical evidence of aspiration of gastric contents in both group. CONCLUSION: In comparison with ETT, use of LMA does not appear to increase the incidence of gastroesophageal reflux and regurgitation above hypophryngeal level in positive pressure ventilating patients during long surgical procedures. Therefore, the risk of aspiration in LMA will not be much more than ETT.

BACKGROUND: Abnormal platelet activation has been identified in several disorders characterizedby vascular patholo-gy including coronary artery disease, Alzheimer disease, myeloproliferative disorders, diabetes, preeclampsia, inflam-matory bowel disease and glomerular disease. Antiplatelet therapy has been valuable in the management of some of these conditions. The aim of this study is to verify usefulness of mean platelet component (MPC) concentration as a marker of thrombotic process in patients with cerebral infarction. Our hypothesis is that MPC as measured by the ADVIA(R) 120 hematology system is used to detect and monitor platelet activation associated with thrombotic process of ischemic stroke. METHODS: To study the existence of platelet activation at the onset of cerebral infarction, mean platelet concentration of platelets were measured daily during post-stroke 10 days. Thirty-four acute thrombotic cerebral infarction and seventeen age-matched healthy persons were selected for this study. To investigate the time course of the platelet MPC changes observed in stroke patients, the blood samplings for MPC measuring were done and analyzed on the ADVIA 120(R) system. RESULTS: There was a statistically significant decrease in MPC concentration of the platelets at post-stroke 3rd to 7th day compared to the control group ( p < 0.05). CONCLUSIONS: We conclude that a reduction of MPC as measured by the ADVIA 120(R) hematology system may be used to detect and monitor thrombotic process associated with platelet activation in ischemic stroke.

BACKGROUND: Coronary artery bypass graft (CABG) surgery has been a main treatment modality of ischemic heart disease since Sabiston reported the first CABG operation using a saphenous vein graft in 1963. However, graft stenosis that happens after CABG surgery is one of the main limitations of the procedure. We investigated risk factors that are related to graft stenosis and occlusion in patients that needed a coronary angiogram after CABG surgery. METHODS: From May 1995 to April 2004, we performed 348 CABG surgeries. Among them, we performed follow up coronary angiogram for 45 patients because of clinical indications, corresponding to 146 graft vessels. According to the angiography findings, patients with 27 graft vessels that showed stenosis or occlusion were defined as group S and patients with 119 graft vessels that showed no stenosis or occlusion were defined as group P. RESULTS: The mean patient age of group S is 59.44 (+/-8.549) years and the mean patient age of group P is 57.99 (+/-8.676) years. Group P patients had more stenotic native coronary arteries than group S patients, which is statistically significant (80.0+/-7.2% vs. 68.0+/-11.9%, p=0.005). Group S patients had a statistically significant lower postoperative HDL level than the level of the group P patients (40.4+/-15.9 mg/dL vs. 50.5+/-4.4 mg/dL, p=0.002). CONCLUSIONS: When performing CABG surgery and postoperative patient management, the severity of native coronary artery stenosis and the postoperative HDL level should be considered for better patient outcome.

BACKGROUND: A retrospectiye study was done for understanding morbidity and mortality after major lung resection. MATERIAL AND METHOD: From June 1994 to August 1998, 203 patients received major lung resections for various causes. There were 142 males and 62 females with a mean age of 47.5 years. Initial complains were cough in 47.8%, sputum in 33.0%, hemoptysis or blood-tinged sputum in 23.2%, dyspnea in 18.2%, chest pain in 15.3%, weight loss in 10.8%, fever and chill in 4.9%. There were no complaints in 5.9% of the total patients. The underlying diseases were lung tumor(102 cases/50.2%), bronchectasis(28 cases/13.8%), aspergillosis(24 cases/1.8%), tuberculosis(20 cases/9.9%) and others (29 cases/66.5%) and pneumonectomy(68 cases/33.5%). The postoperative complications were classified as : empyema, BPF, respiratory problem, persistent air leakage over 7 days, arrhythmia, ventilator applied over 24 hours, bleeding, wound infection and chylothorax. The postlobectomy complications were revealed as follow: empyema(3.7%), BPF(2.2%), respiratory problem(5.2%), persistent air leakage over 7days(8.9%), arrhythmia(2.2%), ventilator applied over 24 hours(2.2%), bleeding(1.5%), wound infection(2.9%), chylothorax(0.7%). The postpneumonectomy complications were revealed as follow : empyema(5.9%), BPF (5.9%), respiratory problem(17.6%), persistent air leakage over 7days(0%), arrhythmia(5.4%), ventialtor apply over 24 hours(7.4%), bleeding (7.4%), wound infection(2.9%) and chylothorax(1.5%). Reoperation was done in 8 cases (4.0%). There were 5.8% operative mortalities in pneumonectomy and 0.7% in lobectomy.

PURPOSE: This study was performed to identify the etiologic agents and antimicrobial susceptibility patterns of organisms responsible for bloodstream infections in pediatric cancer patients for guidance in empiric antimicrobial therapy. METHODS: A 5-year retrospective study of pediatric hemato-oncologic patients with bacteremia in Seoul National University Children's Hospital, from 2006 to 2010 was conducted. RESULTS: A total of 246 pathogens were isolated, of which 63.4% (n=156) were gram-negative, bacteria 34.6% (n=85) were gram-positive bacteria, and 2.0% (n=5) were fungi. The most common pathogens were Klebsiella spp. (n=61, 24.8%) followed by Escherichia coli (n=31, 12.6%), coagulase-negative staphylococci (n=23, 9.3%), and Staphylococcus aureus (n=22, 8.9%). Resistance rates of gram-positive bacteria to penicillin, oxacillin, and vancomycin were 85.7%, 65.9%, and 9.5%, respectively. Resistance rates of gram-negative bacteria to cefotaxime, piperacillin/tazobactam, imipenem, gentamicin, and amikacin were 37.2%, 17.1%, 6.2%, 32.2%, and 13.7%, respectively. Overall fatality rate was 12.7%. Gram-negative bacteremia was more often associated with shock (48.4% vs. 11.9%, P<0.01) and had higher fatality rate than gram-positive bacteremia (12.1% vs. 3.0%, P=0.03). Neutropenic patients were more often associated with shock than non-neutropenic patients (39.6% vs. 22.0%, P=0.04). CONCLUSION: This study revealed that gram-negative bacteria were still dominant organisms of bloodstream infections in children with hemato-oncologic diseases, and patients with gram-negative bacteremia showed fatal course more frequently than those with gram-positive bacteremia.

OBJECTIVES: Vitamin D deficiency, which causes secondary hyperparathyroidism, is considered to be a major contributor to osteoporosis. Because the serum 25-hydroxyvitamin D (25-OHD) level depend on sun exposure and, varies by season, the level of serum 25-OHD in each season at which vitamin D status can lead to changes in bone mineral density (BMD) is not known. METHODS: A total of 2,878 women who underwent periodic health examinations at Ajou University Hospital were included in this study. We measured the serum 25-OHD concentrations using radioimmunoassay and BMDs using dual energy x-ray absorptiometry (DXA). The differences in serum 25-OHD levels among groups as a function of age, season, and BMD were tested by one-way ANOVA. RESULTS: The serum 25-OHD level was not different based on age, but by season, with higher levels in the summer and autumn than in the winter and spring. However, the 25-OHD level did not have a significant relationship with BMD in any season. CONCLUSION: The serum 25-OHD level represents vitamin D status at the time of testing, which is not associated with long-term changes in BMD. When the 25-OHD levels are used to make clinical decisions related to the treatment of osteoporosis, careful interpretation is required.

PURPOSE: Although most peritrochanteric fractures in old age necessitates surgical treatment, daily life functions are still impaired after discharge. We assessed the types of peritrochanteric fracture, risk factors, and functional recovery in elderly patients who were over 65 years old. We also tried to determine factors for recovery to daily life. MATERIALS AND METHODS: From January 2006 to December 2007, among 61 patients who were over 65 years old with the possibility of 1 year follow-up, 50 patients were selected through interviews. After verifying age, sex, mode, types of fracture, and method, we analyzed daily living activities with a functional recovery index and estimated recovery of daily life functions after surgery, assuming a score increase if functional recovery was good. RESULTS: The mean age was 75.8 years, and females (31 patients, 62%) exceeded males. Slipping (27 patients, 54%) was the most common cause of fracture, and the intertrochanteric femur fracture was the most common fracture type (34, 68%). The average functional recovery index decreased 16.24% compared with the pre-operation value, having a tendency to decrease more in old age and female patients. Subtrochanteric femur fracture showed a 17.6% decrease in functional recovery index among the fracture types. CONCLUSION: In elderly patients over 65 years, the functional recovery index after peritrochanteric fracture decreased 16.24% on average compared with the preoperation state. The largest decrease was in basic life ability. The functional recovery index decreased more in old age, females, and subtrochanteric femur fracture, which indicates these factors influence functional recovery.
