When performing an endotracheal intubation or tracheotomy to an unconscious patient in emergent situations, one should consider the possibility of later complication of laryngo-tracheal stenosis which can result in difficulties in decannulation. Laryngo-tracheal stenosis is a bothersome problem developing as a complication of treatment by tracheotomy with a cuffed tube and long-term endotracheal intubation with assisted ventilation. One hundred twenty-three cases of laryngo-tracheal stenosis patients during the four yew period from May 1992 to April 1996 were restrospectively reviewed according to several parameters such as the duration of intubation, site of stenosis, treatment modality and, site of tracheostoma. The present report is an analysis of these materials to search for the possible etiologic factors and its proper preventive methods. It was desirable that the endotracheal intubation should be limited within 20 days at most. Tracheotomy performed by non-otolaryngologists has a tendency to be on a higher level of trachea. Technical precautions should be taken into consideration when doing a tracheotomy. The success rate of decannulation of tracheal T-tube was 78.8% and it required average 11 months.

Tracheoesophageal fistula[TEF] is a rare but life-threatening lesion that may occur from ventilation with a cuffed tube. It occurs most frequently when an inlying esophageal tube is also being used-usually for feeding purposes. The mechanism of injury appears to be pressure experted on the tracheal wall by the cuff, which then compresses the "party wall" of the trachea and esophagus against the foreign body that lies in the esophagus. The patient was 32 years old female who had been receiving a treatment of respiratory failure induced by postoperative sepsis with assist ventilator and nasogastric tubal feeding. Sudden attack of abdominal gas distention and massive drainage of gas through N-G tube were developed during assist ventilation in that patient, so we diagnosed as tracheal stenosis with a tracheoesophageal fistula induced by prolonged endotracheal intubation We performed tracheal reconstruction and primary closure of perforated esophagus after weaning ventilator. The postoperative course was uneventiful.eventiful.

The trachea is defined as the airway from the inferior border of the cricoid cartilage to the top of the carinal spur. This paper would confirm the normal tracheal length of Korean adults through the actual measurement using the fiberoptic bronchoscopy. The subjects of this study were 25 patients, 13 males and 12 females between the age of 20 to 69 without abnormality on the neck, trachea, mediastinum and lung pharenchyme on the preoperative chest X-ray, who received the operations from the period of July to September, 1994. For those patients who had heart diseases, the cardiothoracic ratio was below 50%. The measurement was performed on the patients with endotracheal intubation under the general anesthesia in supine and neutral position. The tracheal length was calculated by the difference between the length from the tip of the endotracheal tube [E-tube to carina and to the needle which was inserted into the E-tube at the lower border of the palpated cricoid cartilage, by inserting the broncoscopy through the E-tube. The result was as follow : 1 The measured tracheal length for men was 11.8 0.2 cm[mean standard deviation and women was 10.5 0.3 cm, and that was longer than this [p<0.01 . The average was 11.2 1.0 cm and the standard error was 0.20 cm. 2 According to the correlation between the tracheal length to weight, height[Ht , age, and body surface area[BSA respectively, the Ht [p=0.003 , age [p=0.055 , and the BSA[p=0.017 were significant, while weight was not [p=0.314 . 3 From the regression analysis of the tracheal length[T.L. to the Ht, Age, and the BSA which were significant, the following equation was derived.i Ht : T.L.= -1.29 + 0.076 x Ht [P=0.003 ii Age: T.L.= 10.04 + 0.028 x Age [P=0.055 iii BSA : T.L.= 5.60 + 3.48 x BSA [P=0.017 iv In multi-regression : T.L. = -4.15 + 0.034 x Age + 0.085 x Ht [P=0.0002]

Acquired nonmalignant tracheoesophageal fistulas were formerly considered rare lesions, but they have been increasingly reported in the recent past. The pathognomonic complaints of this life-threatening lesion are strangulating sensations and frequent paroxysmal coughings occurring several seconds after the ingestion of liquids or solids. Until the past decade, this lesion was most often caused by infection, trauma, or esophageal diverticula. Complications caused by cuffed tracheal tubes are now becoming more widely noticed. Especially, tracheoesophageal fistula is one of the more unusual of these complications. Author reports two patients with tracheoesophageal fistula caused by cuffed tracheal tube.

Tracheal invasion is an uncommon complication of thyroid cancer, but it can cause respiratory failure. A rigid bronchoscope may be used to help relieve airway obstruction, but general anesthesia is usually required. Tracheal balloon dilatation and stent insertion can be performed without general anesthesia, but complete airway obstruction during balloon inflation may be dangerous in some patients. Additionally, placement of the stent adjacent to the vocal cords can be technically challenging. An 86-year-old female patient with tracheal invasion resulting from thyroid cancer was admitted to our hospital because of worsening dyspnea. Due to the patient's refusal of general anesthesia and the interventional radiologist's difficulty in completing endotracheal stenting, we performed endotracheal tube balloon dilatation and argon plasma coagulation. We have successfully treated tracheal obstruction in the patient with thyroid cancer by using endotracheal tube balloon inflation and a flexible bronchoscope without general anesthesia or airway obstruction during balloon inflation.

Acquired tracheoesophageal fistula (TEF) can occur rarely from various causes. Recently, cuff-related tracheal injury after endotracheal intubation with the orotracheal tube and tracheostomy cannula is the most common etiology of nonmalignant TEF. Since cuff-related TEF is usually preventable with proper selection of the cuffed tube and close monitoring of cuff pressure. Although most patients present increased secretions, recurrent pneumonia, or coughing after swallowing, a high index of suspicion is required in patients at risk for developing a TEF. Surgical correction for the defectis required. In most cases, primary closure of the esophageal defect and tracheal resection and end-to-end anastomosis give the best results.

문명의 발달로 나날히 복잡해지는 사회 환경속에서 우리는 생명을 위협하는 수 많은 사고를 당하게 되며, 이럭 경우에 상기도를 유지하기 위한 기관절재술을 많이 시행하게 되는데, 때로는 기관협착등 이에 따른 여러가지 합병증을 유발하게 되는 경우가 있으며, 임상가들에게도 곤란한 문제를 갖어다 주고있다. 그러나 이러한 합병증은 수술방법의 개선과 항생제의 출현등으로 그 빈도가 많이 감소되기는 하였으나, 1969년 Lindholm은 술후성 기관협착증의 빈도를 1.5%내지 10%라고 했으며, 1969년 Donnelly, Mulder와 Rubush, 그리고 1971년 Andrew와 Pearson 등은 이들 원인의 대부분이 cuff 가 있는 기관삽입관이나, 기관케뉼(tracheal canula)의 부적합한 사용이나, 또는 감염에 의한 압박괴사(pressure necrosis)로 형성된다고 하였고, 협착부위로서 1972년 Bryce는 절개공(stoma)주위가 가장 많으며, 응급기관절개술시에 의사의 부정요법(mal-practice)도 원인이 될 수 있다고도 주의한 바 있다. 기관협착증의 치료로서 협착이 경미한 경우에는 일차적으로 세심한 관찰을 실시하면서 실리콘관(silicon tube)이나 스텐트(stent)를 사용하거나, 비강을 통한 삽관법(naso tracheal intubation)으로 기계적인 확장을 시도하며 (Schmiegelow, 1929, Montgomery, 1965), 육아조직이 형성되었을 경우에는 기관경검사하에서 이를 제거한 후에 steroid를 병용하는 편이 좋은데(Birck, 1970) 그밖에도 기관개찰술(Fenestration method, 백·홍 1974)이나 재수술(Revision)을 하기도 한다. 이러한 방법으로서도 치료가 불가능한 경우에는 그 협착 부분을 절제한 후에 단단문합술(End-to-End Anasto-mosis)을 시행하는 수도 있다. 저자들은 1967년 10월부터 1977년 3월까지 10연년간 세브란스병원에서 기관절개술을 받았던 1514례를 대상으로 일련의 조사를 실시하여 이들 중에서 기관협착증을 유발한 23례를 치료하였으며, 여기서 몇가지 지견을 얻었기에 보고하는 바이다.

Purpose: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. Method: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. Result: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=.038). More subjects in the no aspiration group ($73\%$) than the aspiration group ($56\%$) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. Conclusion: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

배경: 기관 협착의 치료방법은 비교적 덜 침습적인 기관지내시경을 이용한 시술 또는 침습적인 방법인 구역절제술과 문합의 방법이 있으나 가끔은 환자의 임상적 특징에 따라 이 모든 방법이 불가능할 때도 있다. 최근 실리콘 T-튜브 스텐트가 안전한 치료 대안이 되고 있다. 우리는 다양한 기저질환을 가진 기관 협착 환자에서 T-튜브의 중단기 결과를 조사하였다. 대상 및 방법: 1997년 1월부터 2007년 4월까지 10년 동안 T-튜브로 기관협착을 치료받은 환자 57명을 후향적으로 검토하였다. 환자의 의무기록과 영상검사를 기초로 하여, 임상적인 결과와 T-튜브 제거유무를 조사하였다. 결과: T-튜브와 연관된 합병증과 사망은 없었다. 경과 관찰 기간 동안 1명의 환자는 협착부위 절제와 재건술을 받았다. 13명의 환자들(13/57, 22.8%)은 성공적으로 T-튜브를 제거하여 더 이상 다른 처치는 필요하지 않았다. 또 다른 4명의 환자는 기관연화와 기관협착의 재발로 T-튜브 제거 후 다시 삽입하였다. 4명의 환자들은 기저질환과 암으로 사망하였다. 성별과 T-튜브 삽입 전 기관절개술 유무는 T-튜브 제거에 상당한 영향을 미치나 다변량 분석에서는 성별만이 T-튜브 제거 성공의 표지자로 밝혀졌다. 성별 (p=0.033)과 이전의 기관절개술(p=0.036)은 T-튜브 제거 성공군과 실패군 간의 2가지 다른 요소였다. 결론: T-튜브는 여러 원인에 의해 유발된 기관 협착에서도 믿을 만한 기도유지를 제공하였다. T-튜브는 중단기 동안 기관협착의 치료에 안전하고 효과적인 방법이라고 생각된다.
