Purpose : The purpose was to investigate the clinical considerations of patients affected by meconium aspiration syndrome (MAS) and the effect of suctioning through endotracheal intubation immediately after delivery on the prognosis of MAS. Methods : A total of 44 inpatients diagnosed as MAS in the Neonatal Intensive Care Unit (NICU) at Cheil Hospital were selected from January 2004 to June 2006. They were divided into two groups. In the early aspiration group (12 patients), suctioning through endotracheal intubation was performed according to the neonatal resuscitation program of the American Academy of Pediatrics and the American Heart Association because infants born through meconium-stained amniotic fluid (MSAF) were not vigorous after birth. In the early non-aspiration group (32 patients), endotracheal intubation was not performed because the infants born through MSAF were vigorous after birth. These two groups were analyzed retrospectively by medical records in the fields of clinical features, obstetric risk factors, complications, treatment, and duration of hospitalization. Results : There was no significant difference in mean gestational age, mean birth weight, sex, and delivery mode between the early aspiration group and the early non-aspiration group. Mean Apgar score of the early aspiration group both in 1 and 5 minute score was significantly lower than in the early non-aspiration group. Lengths of hospitalization and duration of mechanical ventilator care were longer in the early non-aspiration group, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group than in the early aspiration group. Conclusion : In this study, the early non-aspiration group used surfactant more and had a longer duration of mechanical ventilator and hospitalization, but there was no significant difference. Total duration of oxygen therapy was significantly longer in the early non-aspiration group. Therefore, more detailed guidelines for vigorous infants born through MSAF are needed and we should study and follow up the long term prognosis of neurological complications of MAS.

One of major problem in endotracheal intubation for general anesthesia is intrathoracic tracheal obstruction induced by tumor such as, intrathoracic goiter and malignant lymphoma etc. Small amount of secretion or hemorrhage and mild tracheal edema may cause aggravation of tracheal obstruction during endotracheal intubation. Also, it is too difficult to perform the emergency tracheostomy in middle tracheal obstruction. We tried to perform femorofemoral cardiopulmonary bypass without endotracheal intubation for induction of general anesthesia in case of middle tracheal obstruction and We reported with review of literature.

Eight patients underwent tracheal resection and reconstruction for tracheostomy and postintubation injuries from 1971 to early 1981. The ages ranged from 12 years to 59 years. The patients had 7-cuff stenosis and one stomal lesion in whom intubated long. Four male and four female patients were treated. Cervical approach was used in one, cervicomediastinal in 3 and transthoracic in four. The longest length of resection extended to 4 cm in whom cervico-upper half mediastinal incision and neck flexion were applied. Techniques for obtaining tension-free anastomosis included cervical flexion or division of the inferior pulmonary ligament and mobilization of the right hilum. Concurrent tracheostomy was not needed in all. There was one death at the end of emergency operation from anesthetic accident. Granulations at the anastomosis line, necessitating bronchoscopy, were noted in two and the lesion did not recurred after removal. No restenosis or other complications occurred during long follow-up.

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.

Unplanned extubation prevention program (UEPP) was developed and applied to intubated patients hospitalized in a medical intensive care unit (ICU). The number of unplanned extubation was 29 during the preliminary investigation and 23 cases during the prevention intervention program. The general features of the patients and nurses who experienced UE did not have any significant differences between the two periods, with only the number of new nurses in the ICU being significantly different (p=.039). Although the number of new nursing staff in the ICU was high, the mean rate of unplanned extubation, which is the number of UE days per 1000 intubation days, was 8.8 during the prevention intervention program, which was significantly lower than 12.3, the mean rate of UE during the preliminary investigation (t=-2.333, p=.040). The results provide a prevention program that could contribute to the safety of patients by actively preventing unplanned extubation in intubated patients in ICU.

Acquired tracheoesophageal fistula is a rare but serious condition which is usually a result of prolonged intubation or tracheostomy statc, and is difficult to treat. A fifty-seven year old woman who was in a state of prolonged intubation and tracheostomy following a traf%c accident, presented with recurrent aspirati n. A tracheoesophageal fistula was demonstrated ) cm above the carina by csophagogram. We confirmed a subglottic web and tracheoesophageal fistula by bronchoscopic examination. Fistulectomy was performed with collor incision and partial sternotomy. The esophagus was repaired by two-layer interrupted suture using 4-0 Vicr)1, and the trachea was repaired by single layer suture using a 4-0 PDS. The sternohyoid muscle was interposed between the trachea and the esophagus. A T-tube was inserted through the previous tracheostomy site for easy tracheal suction and maintenance of the tun:on. The T-tube was removed on the 14th postoperative day, and the patient recovered well without any complications.

Laryngo-tracheal perforation caused by the use of a stylet during tracheal intubation is a rare complication. We present a case of subcutaneous emphysema and connective tissue inflammation after tracheal intubation. The patient was a 41-year-old male undergoing general anesthesia for an appendectomy. The intubation was difficult during laryngoscopy (Cormack- Lehane Grade III). An assistant provided an endotracheal tube with a stylet inside while the laryngoscope was in place. During intubation, a short, dull sound was heard with a sudden loss of resistance after the distal tip of the endotracheal tube passed the rima glottis. A sonogram and computerized tomography revealed subcutaneous emphysema from the neck to the upper mediastinum and fluid collection between the trachea and the thyroid. This lesion appeared to have been caused by the protruded, loose stylet. Anesthesiologists should be aware of the damage a loose stylet protruding beyond the tip of the endotracheal tube can cause.

Hypopharyngeal perforation secondary to tracheal intubation is rare, but may result in severe airway complications that include retropharyngeal abscess, pneumothorax, pneumonia, mediastinitis and death. The most common site of hypopharyngeal perforation is the pyriform sinus and the region of the cricopharyngeus muscle. We report a 62-year old man with intubation-induced hypopharyngeal injury presenting as deep neck infection. The patient presented with dyspnea and pain on the neck. Neck CT scan identified fluid and air collection on the neck from the hyoid bone to the thoracic inlet level. Despite of delayed diagnosis, we successfully operated him by using strap muscle myofascial transposition flap. The patient was followed up for 3 months without any complications.

Tracheal stenosis is a difficult disease entity to manage. Laser ablation is one effective treatment for treacheal stenosis and can be utilized if tracheal reconstructive surgery is impossible. Potassium titanyl phosphate laser, transmitted via flexible quartz fiber, can be precisely manipulated through flexible bronchoscope under local anesthesia. We treated 7 patients with trach al and broncheal lesion under local anesthesia with KTP laser from January 1995 to July 1996. The patients included three males and four females. The age of patients ranged from 22 to 66 years with a mean of 43.7 years The etiology of tracheal stenosis in patients was stenosis after tracheostomy(3 cases), prolong inturbation in cases of sepsis(1 cases), and the recurrence of lung cancer within endobronchial lesion(2 cases). In the cases of tracheal stenosis treated with laser ablation, there were 2 cases of recurrence of stenosis at the anastomosis site after the operation, 3 cases of stenosis at tracheostomy site, and 2 cases of local recurrence of lung cancer. The site of the tracheal stenosis was the balloon site of the tracheostomy tube(3-4cm inferior to the tracheostomy site, 2-3cm superior to the carina) and the anastomosis site that were narrowed to less than 5mm(4 cases). For the stenosis lesion in the endobronchial area, there were 2 patients with a lesion at the anterior wa l, 1 patient with a lesion at the posterior wall, 2 patients with circumferential stenosis. Laser ablation time was 25.4 $\pm$5.9min and used energy was 1768 $\pm$365J. We have used KTP laser via (lexible bronchoscope without major complications. Adjuvant radiation therapy may prevent fibroblast proliferation which leads to restenosis. In three patients of restenosis after laser ablation, adjuvant irradiation started within 4 hours after laser ablation, and the radiation doses were 1500cGy given in five fraction. In patients with adjuvant radiation therapy, stenosis has not recurred
