Fractured tracheostomy tube presenting as foreign body in the tracheobronchial tree is very rare. Authors experienced a case of broken tracheostomy tube presenting as a foreign body in the trachea, which was removed with the help of flexible bronchoscope. A few causes could be suggested for the tube break: aging and deterioration of the tube with repeated use, a flaw of the tube in the manufacturing process, and a wrong sterilization.method causing weakness of the tube. We report this case with brief literature review.

This study was conducted to investigate the use of medical equipment in patients receiving home care service. The subjects of this study were 88 patients cared by seven home care nursed who were registered in the Seoul Nurses Association. Data was collected from Aug. 1, 1998 to Dec. 30, 1998. The findings are as follows. 1. The sample was found to be 55.7% female : 51.7% over 65 years old. 75% with neurologic disease including CVA, brain tumor, ICH, Parkinsonism & Spinal stenosis and 78.4% living in Seoul. The Clinical experience of the home care nurses was greater than five years. 2. Medical equipment which the patients possessed were foley catheters(61.4%), L-tubes(59.1%) and tracheostomy tubes(51.1%). 3. Technical difficulties in use of medical equipment were related to home care ventilators(60.0%), L-tubes(3.8%) and tracheostomy tubes(2.2%). 4. Most of the medical equipment were obtained from the hospital where they had been admitted previously or from medical equipment companies. 5. Complications from the use of this equipment were infection through invasive techniques including wound drainage tubes(50%), and IV injections(22.2%), The complications were resolved through referral to the doctor of the hospital where they were previously admitted or through community health centers. 6. Most of the equipment was disposable, and equipment was disinfected by using various methods including boiling and soaking in antiseptic solutions. These findings suggest that consistant policy on the management of medical equipment is necessary for the safety of home care patients.

Acquired, nonmalignant tracheoesophageal fistula is an uncommom and difficult problem to manage. The most commom cause is a complication of endotracheal or tracheostomy tubes. Most are diagnosed while patients still require mechanical ventilation. The principle of treatment is two stage operation. First, new tracheostomy tube is placed so that the baloon is below the fistula, and gastrostomy and feeding jejunostomy are made for the drainage and feeding. Finally after weaning from the mechanical ventilation, tracheal resection and reconstruction are made, and the esophageal defect is closed in two layers and a viable strap muscle interposed into the two suture site to prevent recurrence. Recently, we experienced a case of acquired nonmalignant tracheoesophageal fistula which was developed during mechanical ventilation. She was successfully treated with the above two stage operation.

Background: Montgomery T-tube is widely used to maintain airway in many cases. Market-available tubes are not always fit to the trachea of each patient and need some modification such as trimming. Complications do happen in prolonged use like tracheostomy tubes. To overcome above limitations, we designed custom-made T-tube using CT data with the aid of 3D reconstruction software. Material and Method: Boundaries were extracted from neck CT data of normal person and processed by surface rendering methods. Real laryngotracheal model and tracheal inner surface-mimicking tube model were made with plaster and rubber. The main tube was designed by accumulation of circles or simple closed curves made from boundaries. Stomal tube was made by accumulation of squares due to limitation of software. Measurement data of tracheal lumen were used to custom-made T-tubes. Tracheal lumen residing portion (vertical limb) was made like circular cylinder or simple closed curved cylinder. Stomal portion (horizontal limb) was designed like square cylinder. Results: Custom made T-tube with cylindric vertical limb and horizontal limb of square cylinder was designed. Conclusion: CT data was helpful in making custom made T-tube with 3D reconstruction technique. If suitable materials are available, commercial T-tube can be printed out from 3D printers.

Despite improvement in respiratory care, including use of low pressure and high volume cuffed tubes, tracheal stenosis remains a serious complication after a long-term tracheal intubation and tracheostomy. In such patients, tracheal resection and primary anastomosis is still considered ideal therapeutic modality. Between 1989 and 1997, we performed tracheal resections with end-to-end anastomosis on 14 patients with no operative mortality and some morbidity. Tracheal stenosis was caused by tracheostomy in nine patients, by endotracheal intubation in three patients and by thyroid carcinoma in two patients. The length of stenosis was various from 2cm to 4.5cm. All patient underwent segmental tracheal resection and primary anastomosis(14 patients) and additional procedures were cricoid cartilage reconstruction(2 patients), suprahyoid laryngeal release(3patients), carinal release technique(2 patients) and arytenoidectomy(2 patients). We have nine complications: granulona at anastomosis site in four patients, vocal cord palsy in two patients and restenosis, pneumonia, skin necrosis in each of those patients. The granuloma was removed by bronchoscopic forceps(4 patients). Vocal cord palsy was treated by arytenoidectorny(2 patients), restenosis by T-tube insertion, pneumonia by antibiotics and skin necrosis was treated by skin graft. We reviews our expenence of clinical features of tracheal stenosis and surgical treatment by tracheal one-to-end anastomosis with additional procedures to avoid postoperative complications for sucessful results.

Purpose: The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods. Method: The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II). Results: Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M=61.61mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%). Conclusion: Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a $50_cc$ syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.

Despite improvement in respiratory care, including widespread use of low pressure and high volume cuffed tubes, tracheal stenosis remains a feared complication of prolonged intubation and tracheostomy. In such patients, other coexisting problems such as vocal cord paralysis, tracheoesophageal fistula, noncontiguous stenotic segments and laryngeal stenosis may occasionly be encountered. Therefore tracheal stenosis still presents a significant management problem, despite recent endoscopic advances and surgical techniques. Between 1991 and 1994, authors preformed tracheal resection with end-to-end anastomosis on 11 patients with tracheal stenosis. The total success rate (asymptomatic patients with patent airway) was 72.7% and there were no serious complication. This report reviews our experience about this procedure and surgical results. And it investigates associated factors for successful results.

Tracheal stenosis is being encountered more frequently as ventilatory support and cuffed tubes are increasingly used for treatment of respiratory failure. We experienced 13 cases of tracheal stenosis treated surgically at department of Thoracic and Cardiovascular Surgery, school of medicine, Kyung Hee university during the 4 years. The causes of tracheal stenosis were prolonged endotracheal intubation 5 cases, tracheostomy 3 cases, tracheal tumor 2 cases, thyroid tumor 1 case and congenital double aortic arch 1 case. The methods used to manage the tracheal stenosis were tracheal resection % end to end anastomosis 8 cases, 2 cases of subglottic stenosis were underwent primary laryngotracheal anastomosis, Lt. aortic arch division 1 case, and stent insertion 2 cases. In two cases, who had 6 cm in length of tracheal stenosis, we were underwent tracheal resection k end to end anastomosis with supralaryngeal release procedure. Postoperative courses were uneventful except one case with tracheal tumor.
