Background : Mechanical ventilation constitutes the last therapeutic method for acute respiratory failure when oxygen therapy and medical treatment fail to improve the respiratory status of the patient. This invasive ventilation, classically administered by endotracheal intubation or by tracheostomy, is associated with significant mortality and morbidity. Consequently, any less invasive method able to avoid the use of endotracheal ventilation would appear to be useful in high risk patient. Over recent years, the efficacy of nasal mask ventilation has been demonstrated in the treatment of chronic restrictive respiratory failure, particularly in patients with neuromuscular diseases. More recently, this method has been successfully used in the treatment of acute respiratory failure due to parenchymal disease. Method : We assessed the efficacy of Bilevel positive airway pressure(BiPAP) in the treatment of acute exacerbation of chronic obstructive pulmonary disease(COPD). This study prospectively evaluated the clinical effectiveness of a treatment schedule with positive pressure ventilation via nasal mask(Respironics BiPAP device) in 22 patients with acute exacerbations of COPD. Eleven patients with acute exacerbations of COPD were treated with nasal pressure support ventilation delivered via a nasal ventilatory support system plus standard treatment for 3 consecutive days. An additional 11 control patients were treated only with standard treatment. The standard treatment consisted of medical and oxygen therapy. The nasal BiPAP was delivered by a pressure support ventilator in spontaneous timed mode and at an inspiratory positive airway pressure $6-8cmH_2O$ and an expiratory positive airway pressure $3-4cmH_2O$. Patients were evaluated with physical examination(respiratory rate), modified Borg scale and arterial blood gas before and after the acute therapeutic intervention. Results : Pretreatment and after 3 days of treatment, mean $PaO_2$ was 56.3mmHg and 79.1mmHg (p<0.05) in BiPAP group and 56.9mmHg and 70.2mmHg (p<0.05) in conventional treatment (CT) group and $PaCO_2$ was 63.9mmHg and 56.9mmHg (p<0.05) in BiPAP group and 53mmHg and 52.8mmHg in CT group respectively. pH was 7.36 and 7.41 (p<0.05) in BiPAP group and 7.37 and 7.38 in cr group respectively. Pretreatment and after treatment, mean respiratory rate was 28 and 23 beats/min in BiPAP group and 25 and 20 beats/min in CT group respectively. Borg scale was 7.6 and 4.7 in BiPAP group and 6.4 and 3.8 in CT group respectively. There were significant differences between the two groups in changes of mean $PaO_2$, $PaCO_2$ and pH respectively. Conclusion: We conclude that short-term nasal pressure-support ventilation delivered via nasal BiPAP in the treatment of acute exacerbation of COPD, is an efficient mode of assisted ventilation for improving blood gas values and dyspnea sensation and may reduce the need for endotracheal intubation with mechanical ventilation.

In August 2000, the American Heart Association and the European Resuscitation Council published the conclusions of tile International Guidelines 2000 Conference on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care which contains both the new recommendations and an in-depth review. The most important changes in the recommendations according to the authors are discontinuation of the pulse-check for lay people, 500 ml instead of 800∼1,200 ml tidal volume during bag-valve-mask ventilation (FiO2 > 0.4) of a patient with an unprotected airway, unifying correct endotracheal intubation size as 8.0 mm, vasopressin (40 units) and epinephrine (1 mg) as comparable drugs to treat patients with ventricular fibrillation, early prehospital survey and intravenous lysis for patients who have suffered coronary artery syndrome and stroke.

The trauma has been known as a major etiologic factor in temporomadibular joint disorders. The endotracheal intubation is suspected as one of the traumatic factor to temporomandibular disorder. But there are few reports about the amount of mouth opening during endotracheal intubation and temporomandibular joint disorder after endotracheal intubation. The authors studied the effects of endotracheal intubation to temporomandibular joint with 70 patients given surgical operation through general anesthesia. The results were as follows. 1. The mean amount of mouth opening for entire patients during endotracheal intubation was 26.3mm (s, d : 2.6), for oral intubation group 25.9mm(s, d : 3.2), for nasal intubation group 26.6mm(s, d : 1.9). There was no difference between two group stastically. (p<0.05) 2. 1 week later endotracheal intubation, the maximum mouth opening increased 1.5mm for entire patients, 1.5mm for oral intubation group, 1.6mm for nasal intubation group than behare endotracheal intubation. 3. Five patients complained the discomforts around temporomandibular joint after endotracheal intubation. The amount of mouth opening during endotracheal intubation was within physiologic range. It seemed that $45^{\circ}$ upward endoscopic lifting for exposure of glottis gave trauma to temporomandibular joint.

A 51-year-old male with chronic renal failure had marked swelling and tenderness of the right arm. Venography revealed central vein occlusion involving stenosis of right proximal subclavian vein, right internal jugular vein, and left distal innominate vein, and obstruction of right brachiocephalic vein. Multiple obstruction of these veins was thought to have resulted from repeated subclavian catheterization. Right subclavian-superior vena cava was bypassed with 10 mm Gore-tex vascular graft and then left subclavian vein with 8 mm Gore-tex vascular graft was bypassed to the 10 mm Gore-tex vascular graft. The results were excellent.

We describe here two cases of anterior tracheoplasty utilizing an autologous pericardial patch. One patient was a 9 year-old female who had a congenital long tracheal stenosis associated with major vascular anomalies including pulmonary artery sling. One-stage correction was done under the support of an extracorporeal membrane oxygenation system. She required a prolonged ventilation support for 10 days postoperatively until the implanted pericardium was fixed to the mediastinal structures. The other patient was a 8 year-old male who had acquired tracheal stenosis following a complicated tracheostomy. By applying additional support over the pericardial patch with the costal cartilage, an endotracheal tube could be removed immediately after the operation. Both patients have been doing well in a postoperative follow-up of over a year, and there have been evidences of growth in the reconstructed trachea.

Background : Endotracheal intubation is one of the methods most securely establishing airway. But accompanying hemodynamic responses are harmful to coronary or cerebral vascular disease patients. These hemodynamic responses are regarded as the results of sympathetic stimulation due to pharyngolaryngeal stimulation, and sympathetic blocking method-stellate ganglion block- may be obtundate these hemodynamic responses. Methods : 75 patients of ASA physical status I-II were selected. There were 40 patients normotensive (Group I), 35 patients hypertensive (Group II) Group I, steliate ganglion block was performed on 20 patients (Group I-S) the remainder had no procedure (Group I-O). Group II, 18 patients received SG3 (Group II-S), 17 patients had no procedure (Group II-O). SGB was performed with 1% lidocaine 8 ml on right stellate genglion after patient's consent. Blood pressure (IIP) and pulse rate(PR) were first measured in the pre-anesthesia room. Follow up BP and PR are checked immediately following SGB and every 5 minutes for subsequent 20 minutes, then after arrival at operatig room, then immediately after intubation and at 3, 5, 10, 15 and 20 minutes after incubation. Results : All group experienced significantly increased blood pressure and pulse rate upon arrival at the pre-anesthesetic and opeating rooms, as compared to when patients rates in the ward. After intubation and for subsequent 5 minutes, significant changes were measured. Patients then recovered to preblock value. In Group I, no statistical significance was recorded between subgroup I-S and I-O. However in Group II, there were significant differences between sub-group II-S and II-O. In evaluating pulse rate changes, there were no significant differences between Group I-S and I-O; nor II-S and II-O. Conclusion : The proper diagnosis of Stellate Ganglion Block had some measure of protective effect on hemodynamics following endotracheal intubation, especially in hypertensive patients.

The Multidrug-resistant Acinetobactor baumanii (MDRAB) is an opportunistic pathogen. Patients with long periods of hospital stay and/or under intensive care unit (ICU) receiving invasive management are more susceptible to this pathogen. In this report, four children with MDRAB infection are reviewed and described their clinical characteristics. There had been concurrent outbreaks of MDRAB infection in adult patients in the ICU at this period of time. The first child had received a craniotomy and epidural hematoma evacuation. The second child was admitted for status epilepticus with hydrocephalus. The third child had pneumonia with status epilepticus with hydrocephalus. The fourth child had poor activity due to hypoxic ischemic encephalopathy and convulsive disorder. Except the fourth child, all had not been exposed to carbapenem prior to infection of MDRAB. That imply the cause of MDRAB infections may be associated with invasive management and prolonged hospitalization together with the previous exposure to carbapenem in our cases. We would like to emphasize the importance and minimizing the spread of hospital infection in patients under prolonged intensive care management regardless of the use of carbapenem.

The technique of radial artery cannulation and its complications are well documented, but serious complications are rare. This is a report of one case of amputation of wrist due to finger necrosis developed from the radial artery cannulation in patient who had craniectomy surgery. This 52-year-old 70kg male underwent subdural hematoma removal surgery. Right radial artery cannulation was carried out percutaneously using 22 gauge Teflon extracath needle after modified Allen's test appeared to be positive. It was intermittently flushed by heparinized solution. His arterial blood pressure was maintained 100/70 - 110/80mmHg and 5 units of banked whole blood and 1 unit of fresh frozen plasma were transfused during 8-hours operation. Cannula was removed on the 9th hour after operation because that was obstructed. On the 12th hour after removal of cannula, his right hand noted to be cool and cyanotic. So, warm towel and hot bag applied continuonsly on the right hand and the right stellate ganglion block was carried out everyday for 4 times. However, on the 10th day after removal of cannula, necrotic change of all fingers of the right hand became worse and skin of fingers were shrunken. Therefore, disarticulation of the right wrist carried out on the 71th day of his hospitalization.

Chylothorax is denned by extravasation of the milky fluid to pleural cavity from the thoracic duct or it's main branches due to operative trauma, congenital lesions, diagnostic procedures, tumor, etc. Another rare cause is diffuse pulmonary Iymphangiomatosis which is uncommon and not well charact rized. We experienced a case of the bilateral chylothorax caused by the diffuse pulmonary Iymphangiomatosis. The patient was at years old girl with symptoms of coughing and febrile sensation, and the chest radiographs showed bilateral pleural effusion and interstitial infiltrates. The laboratory data of the pleural effusion was identified as chile. Uncontrollable with closed tube thoracostomy, division of tHe thoracic duct and biopsy were decided. Biopsy showed anastomosing endothelial lined spaces along the pulmonary Iymphatic routes especially in pleural and interlobar septum, and smooth muscle at the proliferative interstitium of the Iymphatic duct was observed. Postoperatively, chylothorax was controlled with several trial of chemical pleurodesis. Af'leer discharge from the hospital, she was well for ten months follow up.

Acute epiglottitis is a life threatening inflammatory. disease of the upper airway mainly in children, however, the recent reports about acute epiglottitis in adults are increasing. The common symptoms are sore throat, dysphagia, dyspnea and salivary drooling. As the laryngeal edema progresses, the patient sits up, leans forward, with the chin thrust forward, having obvious difficulty breathing. Early recognition and proper airway maintenance until the inflammatory edema subsides are essential steps to avoid a possible life threatening upper airway obstruction. We experienced two cases of acute epiglottitis with sitting up position, chin thrust forward, having dyspnea.
