Deep neck infection is an infection in the potential spaces and fascial planes of the neck, either with abscess formation or cellulitis. In the preantibiotics era most cases of deep neck infection were secondary to an oropharyngeal infection. Moreover, today manupulation of intubation tube and gastroenteroscopy may cause deep neck infection by iatrogenic trauma. We experience 1 case of deep neck infection which originate from pharyngeal penetrating injury following gastroenteroscopy.

In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

Background: The purpose of this study was to evaluate the clinical application of modified Burns Wean Assessment Program (m-BWAP) scoring at first spontaneous breathing trial (SBT) as a predictor of successful liberation from mechanical ventilation (MV) in patients with endotracheal intubation. Methods: Patients requiring MV for more than 72 hours and undergoing more than one SBT in a medical intensive care unit (ICU) were prospectively enrolled over a 3-year period. The m-BWAP score at first SBT was obtained by a critical care nursing practitioner. Results: A total of 103 subjects were included in this study. Their median age was 69 years (range, 22 to 87 years) and 72 subjects (69.9%) were male. The median duration from admission to first SBT was 5 days (range, 3 to 26 days), and the rate of final successful liberation from MV was 84.5% (n=87). In the total group of patients, the successful liberation from MV group at first SBT (n=65) had significantly higher m-BWAP scores than did the unsuccessful group (median, 60; range, 43 to 80 vs. median, 53; range, 33 to 70; P<0.001). Also, the area under the m-BWAP curve for predicting successful liberation of MV was 0.748 (95% confidence interval, 0.650 to 0.847), while the cutoff value based on Youden's index was 53 (sensitivity, 76%; specificity, 64%). Conclusions: The present data show that the m-BWAP score represents a good predictor of weaning success in patients with an endotracheal tube in place at first SBT.

Purpose: To investigate the differences in postoperative sore throat and hoarseness by adjustment of endotracheal tube cuff pressure (CP) during nitrous oxide ($N_2O$) and air anesthesia. Methods: A one-equivalent control group pretest-posttest design was used. Data were collected from August 8 to October 19, 2017 and analyzed using the independent t-test and repeated measures ANOVA. Eighty-four participants were enrolled and divided into three groups: 28 in the Control Group (CP adjusted every 30 minutes using $N_2O$), 28 in Experimental Group 1 (CP adjusted every 10 minutes using $N_2O$), and 28 in Experimental Group 2 (non-adjusted CP using air), all of whom underwent urologic, gynecologic, and orthopedic surgeries at the G University hospital. Sore throat was assessed using a numeric rating scale; hoarseness was evaluate using the Stout classification at 1, 6, and 24 hours after surgery. Results: Scores for sore throat and hoarseness were significantly different between the groups at each measurement time, and scores were consistently higher in the control group. During subsequent measurements, sore throat and hoarseness scores were significantly lower at 6 hours. Cuff pressure changed significantly using air anesthesia (${\chi}^2=10.41$, p=.015) up to 2 hours after induction. Severe sore throat and hoarseness was observed for up to 6 hours after surgery. Conclusion: Cuff pressure adjustment at short time intervals would be helpful in reducing postoperative sore throat and hoarseness. Nursing intervention focused on prevention of sore throat and hoarseness should be required up to 6 hours postoperatively in patients undergoing endotracheal intubation.

후천성 기관식도루는 드문 질환이 지만 생명을 위협하는 병변이며 원인중에는 cuff가 있는 tube를 삽관하여 부적절한 관리하에 장기간 인공호흡기 치료를 한 환자에서 발생하는 경우가 가장 많다. 손상의 기전은 cutt에 의해 기관벽에 압력이 가해져서 허혈성 손상과 더불어 염증성 반응이 더해져 압박된 식도와 비정상적 교통이 생기는 것으로 여겨지고 있다. 환자는 25세된 임산부로 중이염의 합병증으로 세균성 뇌막염이 발생하여 장기간의 인공호흡기 치료중 갑작스런 피하기종과 종격동기종이 발생하여 기관지 경과 CT를 이용해 기관식도루가 발생 했음을 확인후 본과에서 수술적 치료를 시행하였다. 수술은 자동봉합기로 기관의 손상부위를 봉합하고 식도 부위는 vlcyl과 Prolene으로 내외층을 단순봉합하였으며 기관과 식도사이에 흉쇄유돌근 절편을 끼워 넣었다. 수술 후 10일째 식도조영술로 기관식도룬가 완전복구되고 식도기능이 정상임을 확인하였으며 퇴원 후 추적조사결과 환자는 별 문제없이 잘 지내고 있다.

Objectives. The age-based Cole formula has been employed for the estimation of endotracheal tube (ETT) size due to its ease of use, but may not appropriately consider growth rates among children. Child growth is assessed by calculating the body surface area (BSA). The association between the outer diameter of an appropriate uncuffed-endotracheal-tube (ETT-OD) and the BSA values of patients at 24-96 months of age was our primary outcome. Methods. Cole formula, BSA, age, height, weight and ultrasound measurement of subglottic-transverse-diameter were evaluated for correlations with correct uncuffed ETT-OD. The Cole formula, BSA, and ultrasound measurements were analyzed for estimation rates in all patients and age subgroups. The maximum allowed error for the estimation of ETT-OD was ${\leq}0.3mm$. Patients' tracheas were intubated with tubes chosen by Cole formula and correct ETT-OD values were determined using leak test. ETT exchange rates were recorded. Results. One-hundred twenty-seven patients were analyzed for the determination of estimation rates. Thirteen patients aged ${\geq}72months$ were intubated with cuffed ETT-OD of 8.4 mm and were accepted to need uncuffed ETT-OD >8.4 mm in order to be included in estimation rates, but excluded from correlations for size analysis. One-hundred fourteen patients were analyzed for correlations between correct ETT-OD (determined by the leak test) and outcome parameters. Cole formula, ultrasonography, and BSA had similar correct estimation rates. All three parameters had higher underestimation rates as age increased. Conclusion. The Cole formula, BSA, and ultrasonography had similar estimation rates in patients aged ${\geq}24$ to ${\leq}96months$. BSA had a correct estimation rate of 40.2% and may not be reliable in clinical practice to predict uncuffed-ETT-size.

Untreated massive hemoptysis, especially in patients with tuberculous-destroyed lung, is a serious complication resulting in considerable morbidity and mortality. We report a case of a patient who had active tuberculosis and a destroyed left lung with massive bleeding. He was transferred to our clinic with intubation of a right-sided Robertshaw double lumen tube and right upper lobe collapse likely due to tube malposition that was presented on chest X-ray. Because hemoptysis had persisted after bronchial arterial embolizaton, we replaced the double lumen tube with a conventional endotracheal tube and inserted an endobronchial blocker into the left main bronchus through an endotracheal tube guided by bronchoscopy to prevent aspiration of blood into the right lung. Left pneumonectomy was performed and hemotpysis was ceased. We suggest that the use of an endobronchial blocker followed by surgery may be a safe and effective modality of treatment in patients with persistent bleeding after bronchial arterial embolization.

Background The indications for surgical airway management in patients with Robin sequence (RS) and severe airway obstruction have not been well defined. While certain patients with RS clearly require surgical airway intervention and other patients just as clearly can be managed with conservative measures alone, a significant proportion of patients with RS present with a more confusing and ambiguous clinical course. The purpose of this study was to describe the clinical features and objective findings of patients with RS whose airways were successfully managed without surgical intervention. Methods The authors retrospectively reviewed the medical charts of infants with RS evaluated for potential surgical airway management between 1994 and 2014. Patients who were successfully managed without surgical intervention were included. Patient demographics, nutritional and respiratory status, laboratory values, and polysomnography (PSG) findings were recorded. Results Thirty-two infants met the inclusion criteria. The average hospital stay was 16.8 days (range, 5-70 days). Oxygen desaturation (<70% by pulse oximetry) occurred in the majority of patients and was managed with temporary oxygen supplementation by nasal cannula (59%) or endotracheal intubation (31%). Seventy-five percent of patients required a temporary nasogastric tube for nutritional support, and a gastrostomy tube placed was placed in 9%. All patients continued to gain weight following the implementation of these conservative measures. PSG data (n=26) demonstrated mild to moderate obstruction, a mean apneahypopnea index (AHI) of $19.2{\pm}5.3events/hour$, and an oxygen saturation level <90% during only 4% of the total sleep time. Conclusions Nonsurgical airway management was successful in patients who demonstrated consistent weight gain and mild to moderate obstruction on PSG, with a mean AHI of <20 events/hour.
