The treatment of choice for post-intubation tracheal stenosis is partial tracheal resection and end-to-end ana-stomosis. The surgical treatment of tracheal restenosis that results from unsuccessful repair of post-intubation tracheal stenosis is not easy. Failed reoperation results in permanent tracheostomy and loss of voice. If the first operation fails, about $4\~6$ months of period for resolution of inflammatory reaction, edema, and fibrosis is needed. The exact evaluation of the patient's status is necessary and success rate of reoperation for the appropriate candidates is over $90\%$. We report the results of treatment in two cases of tracheal restenosis that resulted from unsuccessful repair of post-intubation tracheal stenosis with review of literatures.

Background : Extubation failure and reintubation increase the morbidity and the mortality rate. Several extubation criteria and risk factors for extubation failure have been recommended. However, some patients present with extubation failure even after a planned extubation. The aim of this study was to evaluate the clinical characteristics of patients with extubation failure after a planned extubation. Methods : Thirty one patients who presented with planned extubation were included. Extubation failure was defined as reintubation within 48 hours after extubation. The clinical, respiratory and hemodynamic parameters between extubation success and failure group were compared. Results : Six patients were included in the failure group. The extubation failure rate was 19.4%. The age, periods of intubation and heart rates were significantly different between the extubation success and failure group. In the success and failure group, the mean age were $60.4{\pm}15.65$ vs. $80.3{\pm}7.17$ year, the intubation periods were $7.12{\pm}2.47$ vs. $13.83{\pm}2.4$ day and the heart rates were $94.32{\pm}5.77$ vs. $110.67{\pm}3.78/min$, respectively. Conclusion : Old age and patients intubated for periods will require a will careful assessment before extubation. Extensive cardiac evaluations before extubation will also be needed.

Delayed eruption and abnormal morphology of the primary incisors following intubation may be due to follicular displacement and localized trauma caused by the process of intubation. Result of such damage included palatal groove formation, defective incisors and acquired clefts. This clinical report presents effect of intubation on the primary dentition of premature low-birth-weight children prior to tooth eruption.

후두 형태에 이상이 없는 잡종개 2마리를 정맥 마취한 상태에서 생체 발성 모형을 만들었다. 경부 피부를 수직절개하고 후두 및 기관을 노출시킨 후, 기관에 상, 하 두 개의 기관절개를 가하고 두개의 삽관튜브를 삽입하였다. 아래 튜브로는 호흡을 유지하게 하였고, 위의 튜브로는 공기를 후두 방향으로 보내면서, 상후두신경의 외지와 반회신경 및 반회신경의 최종 분지인 갑상피열 분지에 전극을 각각 부착하여 일정한 정도의 전기자극을 가함으로써 소리가 유발되도록 하였다.(중략)

기관 협착증은 기관 삽관, 기관절개술 혹은 외상 등에 의해 주로 발생하고 드물게 종양이나 염증성 질환에 의해 생길 수 있다. 치료의 원칙은 정상 발성기능을 가진 충분한 기관강을 유지하는데 있으며 여러 치료방법 중 기관절제 및 단단문합술은 다른 방법이 실패하였거나 협착정도가 심한 경우에 시행할 수 있고, 정상기관강을 유지함으로써 해부, 생리학적으로 가장 이상적인 수술방법으로 알려져 있다. 저자들은 1990년부터 1994년까지 경부기관 8례, 경부 및 흉부기관을 동반한 기관협착증 1례에서 기관 절제 및 단단문합술을 실시하였다. 전례에서 suprahyoid release를 시행하였으며, 술중 가능한한 회귀신경은 확인하지 않았으며 술후 2일째 기관발거를 실시하였다. 합병증으로 술후 1례에서 일측성대마비가 있었으며 문합부 육아조직 형성이 2례가 있었으나 전례에서 성공적인 기관발거가 가능하였다.

근래 기관내 삽관을 통한 보조호흡술의 발달과 각종 사고로 인한 경부외상의 증가로 인하여 기관협착증이 속발되는 빈도가 높아지는 경향을 보이고 있다. 기관협착증은 관강의 협소 및 관내 분비물의 저류로 인하여 심각한 호흡곤란을 초래하게 된다. 이러한 기관협착을 치료하기위하여 관강을 증폭시키고, 효율적인 기도점막으로 환원시키기란 쉽지 않다. 최근 3년간 본 교실에서 급성 기관협착 4례(기관외상 2례. 막성협착 2례), 만성 기관협착 6례(stomal stenosis 2례, cuff stenosis 1례, mixed stenosis 3례)에 대하여 기관륜의 재배열(2례), T-tube stenting(5례), 이개연골편을 이용한 기관성형술(1례), 협착부의 제거 및 단단문합술(2례) 등으로 각각 치료한 경험을 문헌고찰과 함께 보고하는 바이다.

Purpose : The incidence of mortality associated with respiratory difficulties is decreasing nowadays contributed to the development of neonatology. However, complications associated with mechanical ventilator are increasing. This study is to determine clinical manifestations, diagnositc availability of the endotracheal tip culture in patients with Ventilator-Associated Pneumonia(VAP) in neonatal intensive care unit(NICU). Methods : A retrospective analysis of 50 neonates who were admitted to the NICU of Kangnam Sacred Heart Hospital and had given mechanical ventilator from 1 January 2000 to 30 June 2003. VAP group defined as neonates who had pneumonia with mechanical ventilation longer than 48 hours. They were classified into VAP group(n=13) and control group (n=37) and the prevalence, microorganisms cultured from the endotracheal tube tip and risk factors were investigated. Results : The prevalence of VAP was 26.0%(n=13) and the most dominant microorganism cultured in our NICU was methicillin-resistant coagulase negative staphylococcus(MR-CNS) in 4 cases. Other microorganisms were Pseudomonas, Enterobacter, methicillin-resistant Staphylococcus aureus(MRSA) and Klebsiella. Gestational age, birth weight, Apgar score, respiratory distress syndrome, retinopathy of prematurity, bronchopulmonary dysplasia, sepsis, renal failure, pulmonary hemorrhage, pneumothorax were not different significantly between two groups except intraventricular hemorrhage(P<0.001) and patent ductus arteriosus(P<0.05). Duration of hospital stay and mortality rate were also not different significantly. Conclusion : VAP occurred at a significant rate among mechanically ventilated NICU patients. Despite of limitation of encotracheal tip culture, the most common microorganism was MR-CNS. We should be aware of occurrence of VAP in NICU neonate who were with mechanical ventilator and should treat with great care.

상부기도 협착의 원인은 장기간의 기관 삽관, 외상, 감염, 종양, 및 선천적인 결함등에 의해 존재하며, 이에 대한 진단은 단순 촬영이나 전산화 단층 촬영술 등으로 쉽게 진단은 가능하나, 적절한 치료 계획을 세우기 위해서는 그 범위 및 정도를 정확히 파악하는 일이 중요하다 최근 방사선 촬영기술의 발달로 현재의 2차원적 단면 영상에서 3차원적 영상으로 발전해왔으며 상부기도 협착 또한 3차원적 영상으로 진단하려는 노력이 시도되고 있다. 이에 저자들은 최근에 경험한 기관 협착증 7례에서 3D CT를 시행하여 협착 부위의 상태를 기존의 단순 촬영 영상 및 2D CT 영상과 비교하였고, 7례의 기관 협착증 중 4례에서 기관 단단 문합술 및 후두 기관 문합술을 시행한 바 수술시 확인된 협착 상태를 3D CT 영상과 비교하였다.

Purpose: The purpose of this study was to determine the factors related to airway failure during endotracheal intubation among patients with and without predicted airway difficulty. Methods: Medical records were examined retrospectively. 329 patients who were admitted to the general ward and underwent endotracheal intubation were included. The incidence of airway failure in the two groups was investigated. Results: The group predicted to have airway difficulty consisted of 79 patients (24.0%) and the group without airway difficulty, 250 (76.0%). The number of cases of airway failure was 50 (15.2%). The factors that were associated with airway failure in the group with predicted airway difficulty were the jaw relaxation score, Cormack-Lehane score, and the device of the first endotracheal intubation attempt. The factors that were associated with the airway failure in the group predicted not to have airway difficulty were the induction agent, jaw relaxation score, Cormack-Lehane score, level of training of the personnel with the first endotracheal intubation success, and the device of the first endotracheal intubation attempt. Conclusion: The prediction of airway difficulty during endotracheal intubation was not effective; however, it was meaningful from the perspective of patient safety.
