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.

Tracheal neurilemoma, an extremely rare benign tracheal tumor that there has been only one case reported in 1996 throughout the nation, is a slowly progressing disease that obliterates the upper airway, delays diagnosis for its symptom similarity to asthma, and makes intubation for operation difficult. Bronchoscopic is therefore needed for diagnosis. There are two options for the treatment methods, a bronchoscopic resection or open surgical resection; however if intubation is difficult, then the bronchoscopic resection is used first to keep the airway open for the surgical resection. In this case, the severe tracheal stenosis impeding intubation made the surgical resection of the primary tracheal neurilemoma with extratracheal mass impossible; therefore, bronchoscopic laser resection was applied first to optain the airway passage for endotracheal intubation, followed by a successful open surgical resection.

Treacher collins 증후군(TCS)는 25,000명에서 50,000명당 1명의 빈도로 발생하는 상염색체우성의 유전질환이다. 상, 하악의 발육 부전, 부정교합, 양측성 이개 기형, 안검렬의 반몽고증 사면, 구순구개열, 외이도 폐쇄, 중이와 내이의 기형으로 인한 청각 소실등의 구강악안면 부위의 특징을 보여 태생 이후 성인기에 이르기까지 여러 차례에 걸친 외과적 수술을 거치게 된다. 하악골의 형성저하로 하악골이 짧고 후방 위치되며 후방 위치하는 혀와 후비공의 협착과 폐쇄로 인해 상기도가 좁아지게 되는데 이로 인해 기관삽관의 어려움이 따른다. 따라서 치근 발육이 미약한 소아청소년 시기의 TCS 환자의 기관 삽관 시 상악 전치부의 손상 가능성이 매우 높다. 본 증례는 전신마취 유도를 위한 기관 삽관 도중 상악 전치의 완전 탈구가 발생한 TCS 환아의 치험례를 통해 기도 삽관 시사전의 마우스가드 제작의 유용성에 대하여 알리고자 한다.

Mask ventilation, the first step in airway management, is a rescue technique when endotracheal intubation fails. Therefore, ordinary airway management for the induction of general anesthesia cannot be conducted in the situation of difficult mask ventilation (DMV). Here, we report a case of awake intubation in a patient with a huge orocutaneous fistula. A 58-year-old woman was scheduled to undergo a wide excision, reconstruction with a reconstruction plate, and supraomohyoid neck dissection on the left side and an anterolateral thigh flap due to a huge orocutaneous fistula that occurred after a previous mandibulectomy and flap surgery. During induction, DMV was predicted, and we planned an awake intubation. The patient was sedated with dexmedetomidine and remifentanil. She was intubated with a nasotracheal tube using a video laryngoscope, and spontaneous ventilation was maintained. This case demonstrates that awake intubation using a video laryngoscope can be as good as a fiberoptic scope.

Purpose : This research was designed to provide basic data for advanced pre-hospital airway management by comparing the ease of intubation, the success rate and the time for intubation performed with Macintosh Laryngoscope, Gum Elastic Bougie and Pentax AirWay Scope on the floor and table. Methods : Intubation was performed 30 times in total, including 5 times for each of intubation using Macintosh Laryngoscope, Gum Elastic Bougie and Pentax Airway Scope on the table and floor, only on subjects who passed the practice test of the national exam for paramedics. Data were collected by measuring the ease of intubation, the success rate and the time for intubation, and then analyzed by descriptive analysis, paired t-test, ANOVA using SPSS 18.0. Results : 1. There was a significant difference in the ease of intubation according to intubation devices. 2. There was a significant difference in the ease of intubation according to table height for intubation. 3. There was a significant difference in the success rate according to intubation devices. 4. There was no significant difference in the success rate according to table height for intubation. 5. There was a significant difference in the intubation time according to intubation devices. 6. There was a partially significant difference in the intubation time according to table height for intubation. Conclusion : Sufficient training not only with Macintosh Laryngoscope but also with Gum Elastic Bougie and Pentax Airway Scope could improve the survival rate by intubation in patients with difficult airway.

한 41세 남자 환자가 충수돌기염 절제술을 받기 위하여 전신마취를 받았다. 삽관을 위해 후두경으로 보자, 난해한 기도삽관이 예상되어 유도자를 사용하였다. 기도삽관 중 돌출된 유도자가 기도를 손상시켰으며, 이에 의해 목에서부터 상부종격동까지의 피하기종과 목의 염증성 종창이 생겼다. 환자는 호흡곤란과 관련된 증상을 보이지 않아 호흡기의 손상을 의심하기 어려웠고, 주 증상이었던 염증성 종창에 초점을 두게 되어 진단에 차질을 빚었으나, 환자는 대증치료로 회복하였다. 유도자를 사용하여 기관내 삽관을 하는 경우 유도자의 위치를 재점검하여 유도자에 의한 기도 손상을 유발하지 않도록 유념해야 할 것이다.

In cases of multiple facial trauma and other specific cases, the anesthesiologist may be asked to convert an oral endotracheal tube to a nasal endotracheal tube or vice versa. Conventionally, the patient is simply extubated and the endotracheal tube is re-inserted along either the oral or nasal route. However, the task of airway management can become difficult due to surgical trauma or worsening of the airway condition. Fiberoptic bronchoscopy was considered a novel method of airway conversion but this method is not useful when there are secretions and bleeding in the airway, or if the anesthesiologist is inexperienced in using this device. We report a successful airway conversion under the aid of both, a fiberoptic bronchoscope and a C-MAC video laryngoscope.

Non-visualization of larynx is one of the reasons for failure of vocal fold surgery. Many otorhinolaryngologists may have a trouble in choice of alternative treatment if they experience this situation. The laryngeal mask airway could be alternative approach for this situation. We report a glottal papillomatous patient who was treated by pulsed dye laser via laryngeal mask airway after failure of vocal fold surgery via endotracheal intubation. The patient was a 73-year-old man. Laryngoscopy revealed a severe diffuse papillomatous lesion on right true vocal cord, anterior commissure, and partial left true vocal cord. The patient was refered for difficult laryngeal exposure during laryngomicrosurgey under general endotracheal anesthesia.

Background: Failure to maintain a patent airway can result in brain damage or death. In patients with mandibular prognathism or retrognathism, intubation is generally thought to be difficult. We determined the degree of difficulty of airway management in patients with mandibular deformity using anatomic criteria to define and grade difficulty of endotracheal intubation with direct laryngoscopy. Methods: Measurements were performed on 133 patients with prognathism and 33 with retrognathism scheduled for corrective esthetic surgery. A case study was performed on 89 patients with a normal mandible as the control group. In all patients, mouth opening distance (MOD), mandibular depth (MD), mandibular length (ML), mouth opening angle (MOA), neck extension angle (EXT), neck flexion angle (FLX), thyromental distance (TMD), inter-notch distance (IND), thyromental area (TMA), Mallampati grade, and Cormack and Lehane grade were measured. Results: Cormack and Lehane grade I was observed in 84.2%, grade II in 15.0%, and grade III in 0.8% of mandibular prognathism cases; among retrognathism cases, 45.4% were grade I, 27.3% grade II, and 27.3% grade III; among controls, 65.2% were grade I, 26.9% were grade II, and 7.9% were grade III. MOD, MOA, ML, TMD, and TMA were greater in the prognathism group than in the control and retrognathism groups (P < 0.05). The measurements of ML were shorter in retrognathism than in the control and prognathism groups (P < 0.05). Conclusions: Laryngoscopic intubation was easier in patients with prognathism than in those with normal mandibles. However, in retrognathism, the laryngeal view grade was poor and the ML was an important factor.
