Chronic fatigue of the respiratory muscles has contributed to the decreased ventilatory capacity and reduced excercise tolerance of individuals with COPD, especially in kyphoscoliosis. Nasal mask BiPAP has been shown to be useful for the patient with nocturnal muscle fatigue and COPD. A 35-year-old man with severe kyphoscoliosis was admitted to ICU due to acute respiratory failure. He had been diagnosed of COPD and had been intubated with mechanical ventilatory support for 7 times. This time he was intubated with ventilatory support, too, in ICU and readmitted to the ICU for severe hypoxemia and hypercarbia from general ward. Thereafter he refused the intubation. Nasal mask BiPAP ventilatory support system was applied and IPAP, EPAP level being adjusted to the 12, 4 cmH2O under monitoring vital signs and arterial blood gas analysis. His condition was improved and discharged home with support of nasal mask BiPAP system after 33 day-stay in the ICU.

Foreign body aspiration into the airway causes airway obstruction that may be acutely life-threatening or if undected result in severe lung damage. In case of bilateral bronchial obstruction, the impairment of gas exchange is usually severe enough to threaten the patient's life. And the gas exchange will become worsen during bronchoscopy. So, anesthesia and bronchoscopy for removal of the foreign body should be carried out by skilled personel with appropriate equipment, especially in case of bilateral bronchial obstruction. A 16 month old, cyanotic and dyspneic female infant was brought to operating room for removal of bronchial foreign bodies . The anesthesia was induced and maintained with enflurane(1-2%) -oxygen(100%)- vecuronium using Jackson- Rees breathing system which was connecting to the side arm of ventilating brochoscope. Foreign bodies (peanut), which were two pieces of peanut 4X4X6 mm sized from right and 4X8X12 mm sized from left main bronchus, were sucessfully removed.

Being described first 1912 by Hashimoto, Chronic lymphocytic thyroiditis has been most commonly diagnosed as inflammatory thyroid disease. Despite of worldwide reports about the concomitant malignancy with Hashimoto's thyroiditis, the definite incidence of coexsiting malignancy and the etiologic relationship between these different pathologic conditions remains to be brought out. Analyzing 18 cases of coexisting thyroid carcinoma among 80 cases of Hashimoto's thyroiditis, confirmed by pathologic study at Presbyterian medical center in Chonju between 1991 and 1995, the authors intended to make guideline of management for them. The results are as follows: 1. The incidence of coexisting carcinoma with HT was 18/80(22.5%). 2. The average age of patients with coexisting carcinoma was 44.1 years and all of them were female.3. Cold nodules on thyroid scan were noticed in 23 cases(22.7%) of HT and 7 cases(33.8%) of coexisting carcinoma with HT. 4. Calcified lesions on thyroid sonography were detected in 0 cases of HT and 4 cases(50%) of coexisting carcinoma. 5. The pathologic types of carcinoma were papillary(17/18, 94.4%) and follicular(1/18, 5.6%). 6. 3 cases of coexisting carcinoma had metastatic lesions on peritracheal lymph nodes and another 3 cases had on ipsilateral jugular nodes. 7. The carcinoma of smaller than 0.5cm were 7 cases, of 0.6-1.0cm were 3 cases, of 1.1-1.5cm were 5 cases, and so 15 cases(83.3%) were occult carcinoma. Only 3 cases were larger than 1.6cm. 8. Coexisting carcinoma patients with HT underwent subtotal thyroidectomy (4 cases), subtotal thyroidectomy & anterior compartment dissection (ACD, 6 cases), subtotal thyroidectomy & modified RND (2 cases), thyroid lobectomy & ACD (4 cases), thyroid lobectomy & modified RND (1 cases), or near total thyroidectomy & ACD (1 case).

BACKGROUND: The wall lift method (W), which was introduced to reduce the adverse effects of CO2 pneumoperitoneum (P), induces an excessive stress response and may be imposed for significant adverse reactions. This study was undertaken to compare the physiologic response of the CO2 pneumoperitoneum and wall lift methods. METHODS: Thirty-two patients were randomly divided into two groups (the P and W). Gastric intramucosal PrCO2, CO2 gap, intramucosal pH (pHi), and plasma concentration of epinephrine and norepinephrine were measured: after the induction of anesthesia, during operation, at the end of the operation, and after operation. Serum concentrations of TNF-alpha and IL-6 were measured at 24 hours before operation, and 24 hours, and 72 hours after operation. The TNF-alpha and IL-6 levels of peritoneal macrophages were also measured. Urine output was measured during operation. RESULTS: PrCO2 and CO2 gap increased during and after the operation in P, and after the operation in W, and pHi decreased during and after operation in P, and after operation in W. Urine output was higher in W. Epinephrine and norepinephrine increased in both groups, but epinephrine was higher in W at the end of the operation. TNF-alpha and IL-6 increased postoperatively and the magnitude of these increases were similar in both groups. The level of TNF-alpha and of IL-6 in peritoneal macrophage were similar in both groups. CONCLUSIONS: We conclude that; CO2 pneumoperitoneum induces intestinal mucosal acidosis, the wall lift method induces more significant stress response, and the magnitude of immune response is similar for both methods.

Light and electron microscopic obserbations of developing heart wall of zebrafish, which has been recently used for developmental studies of many organs, were performed. Heart tissue was obtained from adult and 24, 48 and 72 hour embryos of zebrafish. Heart wall of adult zebrafish was composed of 3 typical layers, endocardium, myocardium and epicardium, as ones of other vertebrates. Heart wall of 24 hour embryo was composed of primitive myocytes. Myofibrils in myocytes at this period was found as assembly of myofilaments, 500~1,000 nm sized and 5~10 layered. Heart of 48 hour embryo has ventricle and atrium. Ventricular wall of was composed of endocardium, myocardium and incomplete epicardium. Atrial wall at 48 hour embryo was composed of endocardium and myocardium. Development of myocytes in ventricle was earlier than those of atrium, and myofibrils with Z disc were found first at 48 hour embryo. Heart wall of 72 hour embryo was morphologically similar to that of 48 hour embryo, but development of myocytes was more progressed. Specific atrial granules of 100~200 nm size appeared very rarely at 24 hour embryo and its numbers increased gradually at 48 and 72 hour embryos in myocytes of atrium as well as the ventricle. Specific atrial granules were consider as ones containing atrial natriuretic peptide (ANP).

Introduction: Lung Injury Score (LIS) provides a quantitative method for scoring acute lung injury that usually occurs after sepsis. The aim of this study is to evaluate the LIS in prediction the patients outcome and determine the relationship between the LIS and mortality rate, acute physiology and chronic health evaluation II (APACHE II) score and multiple organ failure (MOF) score. METHODS: Patients admitted to Intensive Care Unit (ICU), Severance Hospital Yonsei University College of Medicine from November 1995 to March 1996 were included. LIS at admission and discharge, APACHE II score with MOF score and duration of ICU stay between survivors and nonsurvivors were compared. Relationship of LIS between mortality rate and APACHE II score and MOF score were evaluated. RESULTS: LIS is higher in nonsurvivors than survivors at admission and discharge with statistical significance. LIS of survivors and nonsurvivors at discharge was lower and higher than those at admission (p<0.05) respectively. Correlation coeffcient of LIS with mortality rate, MOF score and APACHE II score were 0.60 (p<0.05), 0.23 and 0.17. CONCLUSIONS: LIS score was highly correlated with mortality rate. Therefore LIS is a good predictor of outcome in the intensive care unit.

Anaphylaxis is an acute onset, potentially fatal systemic allergic reaction. Multiple agents can cause anaphylaxis in the perioperative setting. Ketorolac is a potent analgesic drug and has been widely used for postoperative pain control. A 38-year-old male patient, who had surgery under general anesthesia without any problems, was scheduled for a spinal fusion. There were no problems during anesthesia. In post anesthetic care unit, he was given 30 mg of ketorolac intravenously. After the ketorolac injection, severe hypotension and tachycardia developed and delayed skin rash and wheel appeared. The patient was given epinephrine, antihistamine and steroid. The patient recovered without any significant complications.

BACKGROUND: Local anesthetics combined with an opiate are frequently used as a postoperative epidural PCA regimen. Ropivacaine is known to have a selective blockade of the sensory nerve without motor blockade. This study is designed to show advantages of ropivacaine over bupivacaine. METHODS: Patients undergoing elective abdominal and orthopedic surgeries were randomly selected and divided into two groups, B and R. The patients in group B and R received 0.2% bupivacaine and 0.2% ropivacaine respectively through an epidural catheter using a PCA pump. Both local anesthetic solutions were mixed with 4 microgram/ml of fentanyl. The PCA pumps of both groups were set in the same manner. A basal rate of 2 ml/hr was infused from 1hour after the onset of surgery. This basal rate was continued postoperatively. A bolus dose and lock out time were set at 2 ml and 20 minutes respectively. The Visual analogue pain scale (VAS), demand dose, complication and additional intramuscular analgesic requirements were checked up to 24 hours after surgery in 6-hour interval. RESULTS: The VAS was significantly lower in group R than in group B at 6, 12, 18 and 24 hours after the surgery (P < 0.05). Total additional bolus doses of the PCA pump were not significantly different in either group at 6, 12, 18 and 24 hours after surgery. The patients in group R showed more satisfaction and less additional intramuscular injections. CONCLUSIONS: 0.2% Ropivacaine, mixed with 4microgram/ml of fentanyl, was more effective than bupivacaine, mixed with the same concentration of fentanyl, in controlling postoperative pain using an epidural PCA pump.

BACKGROUND: Postoperative nausea and vomiting (PONV) is common complication of Patient-Controlled Analgesia (PCA) after surgery. The authors sought to determine whether a transdermal scopolamine (TDS) patch in combination with IV dexamethasone is more effective than IV dexamethasone alone or IV dexamethasone plus IV ramosetron for reducing PONV in patients receiving epidural PCA after major orthopedic surgery. METHODS: 120 patients that received epidural PCA with hydromorphone and ropivacaine after major orthopedic surgery under spinal anesthesia were allocated to 3 groups: Group D (n = 40) received IV dexamethasone 8 mg, Group DR (n = 40) received IV dexamethasone 8 mg plus IV ramosetron 0.3 mg, Group DS (n = 40) received IV dexamethasone 8 mg plus a TDS patch (Group DS, n = 40). Nausea and vomiting incidences, VAS for nausea, the use of additional antiemetics, and adverse effects (a dry mouth, blurred vision, drowsiness) during the first 24 hours postoperatively were subjected to analysis. RESULTS: The DS Group had a significantly higher rate of complete remission of PONV than the D and DR groups (82.5% vs 47.5%, and 50.0%, respectively), and had lower rates of nausea (17.5% vs 55.0%, and 50.0%), and vomiting (10.0% vs 50.0%, and 25.0%), and required less antiemetics (5.0% vs 35.0%, 22.5%) than group D and Group DR during the first 24 hours after surgery. Furthermore, no inter-group differences were observed with respect to adverse effects in the three groups. CONCLUSIONS: The prophylactic use of a TDS patch plus dexamethasone was found to be a more effective means of preventing PONV in patients that received epidural PCA after major orthopedic surgery than dexamethasone alone or dexamethasone plus ramosetron without adversely affecting side effects.

OBJECTIVE: To estimate false-negative rate of cervical smears in histologically confirmed squamous intraepithelial lesion and squamous cell carcinoma METHOD: From 1993 to 1998, total 186 cases of cervical smear performed within 1 year before histological confirmation squamous intraepithelial lesion and squamous cell carcinoma, were reviewed and the false negative rate of the each group was analyzed. RESULTS: 1. Histologic diagnosis of 186 cases includes 8 cases of low grade SIL, 87 cases of high grade SIL, 91 cases of squamous cell carcinoma. 2. Overall false negative rate was 18.8% (35/186). False negative rate of LSIL was higher (50%; 4/8) compared with the other two groups. (HSIL:23% ;20/87, SCC:12.1% ;11/91) 3. 18 of 35 false negative cases were reviewed. 8 cases(44.4%) were sampling error and 10 cases(55.6%) were interpretation error. 4. Estimated overall sampling error was 8-9% ; interpretation error 10-11%. CONCLUSION: Reducing the false negative rate of cervical smears, especially in cervical intraepithelial neoplasia lesion is important to save the patients from invasive cervical cancer. Further studies on the causes of false negatives and the efforts to eliminate these barriers are actually needed.
