It is well known that intracranial pressure (ICP) and mean arterial pressure (MAP) are increased by laryngoscopy and endotracheal intubation during induction of general anesthesia, and It may be very dangerous in neurosurgical patients who had increased ICP. Therefore, this study was performed to know the range of ICP increase during induction of the conventional general anesthesia with intubation following thiopental and succinylcholine injections. Intracranial pressure and MAP were measured in 13patients who underwent cramotomy. All the patients were monitored cerebral epidural ICP and intra-arterial pressure pre-operatively. The results were as follow: 1. Intracranial pressure was increased of $7.1{\pm}7.23mmHg$. 2. Arterial pressure was increased of $43.5{\pm}25.46mmHg$. 3. Cerebral perfusion pressure was increased of $33.3{\pm}27.53mmHg$. It is stressed that certain procedures are necessary to prevent from further increase of ICP due to induction of general anesthesia in patients with increased ICP.

Tracheal stenosis in children are often the result of prolonged intubation and its treatment depends on the severity and extent of the involved segment. Repeated surgical endoscopic procedures may be indicated in those with mild stenoses mainly consisting of granulation tissues, However, surgical reconstruction of the airway should be performed in patients with severe, extensive stenoses composed of mature scar tissue. The senior author has successfully managed such patients with cartilage graft augmentation and tracheal resection anastomosis. This is a presentation of 9 pediatric patients with tracheal stenosis who have been successfully treated by resection anastomosis. The details of the cases and indications for this type of surgery are discussed.

Purpose: The purpose of this study was to improve airway management ability by comparing the speed, angle of the neck, and confidence and ease of supraglottic airway laryngopharyngeal tube (SALT) and endotracheal intubation via direct laryngoscopy. Methods: The subjects of this experimental research study with a randomized crossover design were 44 emergency medicine technician - paramedics working in the fire department of 'J' - do. SPSS version 19.0 was used in the statistical analysis. Results: Speed and angle of the neck (p<.001), as well as confidence and ease (p<.001), showed significant differences between endotracheal intubation with a SALT and endotracheal intubation via direct laryngoscopy. Conclusion: If endotracheal intubation via direct laryngoscopy is difficult to use or in trauma patients, using a SALT is safe and enables fast intubation. Moreover, in order to improve the efficiency of advanced airway management, the application of SALT should be introduced in the domestic scene.

In recent years there has been considerable interest in reconstructive surgery of the trachea for cervical tracheal stenosis developed by complication of endotracheal intubation or tracheotomy, or trauma of the neck. The methods used to reconstruct the tracheal defects can be repaired with end-to - end anastomosis, cervical flaps, and autogenous graft materials. Since Grillo had undertaken tracheal reconstruction after circumferential resection in dogs, resection and end - to - end anastomosis was used in cases of circumferential stenosis. And, costal, nasal septal and auricular cartilage have been used for the autogenous graft materials. Since Caputo and Consiglio had undergone tracheoplasty with auricular cartilage, Morgenstein reported successful repair of a tracheal defect with a composite postauricular cartilage graft. The advantages of the auricular cartilage graft are its easy accessibility, availability and familiarity to the otolaryngologist. In past 2 years, We performed the tracheoplasty with auricular cartilage graft and end- to end an astomosis after segmental resection in 5 patients who had suffered from tracheal stenosis. And we obtained good results. So, we reported the cases with review of the literatures.

VCP (Vocal Cord Paralysis) is rare but one of most serious complications related to endotracheal intubation. This report is a clinical experience of radiography and laryngeal EMG (Electromyography) assessment for the VCP. A 50-year-old woman with hoarseness, which was occurred after urethral diverticulum excision was examined by laryngoscopy. As a result of laryngoscopy, VCP was observed in left side of her vocal cord, and then recurrent laryngeal nerve damage was detected with additional CT (Computed tomography) scan and laryngeal EMG. After that, the vocal cord movement was recovered as normal state with regular conservative treatment for the 6 months.

Background: This retrospective study aims to describe the airway management and to search predictive parameter for difficult intubation in 700 patients undergoing oromaxillary surgery. Methods: The medical records of 700 patients undergone oromaxillary surgery were reviewed for airway management during perioperative period. The cases of difficult intubation were selected and those radiologic findings were reviewed. The mandibular depth (MD), mandibular length (ML), thyromental distance (TMD) were measured. Results: In 41 cases difficult intubation were recorded in anesthetic record. The grade of Cormack and Lehane was III in 36 patients and IV in 5 cases. The MD of difficult intubation cases was $4.2{\pm}3.2\;cm$. The ML of difficult intubation cases was $10.1{\pm}3.8\;cm$. The TMD of difficult intubation cases was $5.9{\pm}4.3\;cm$. Under the fiberoptic guided awake intubation was undertaken in 75 patient. In none of the cases was failed nasotracheal intubation. Conclusions: The patients undergoing oromaxillar surgery have a potentially difficult airway but, if managed properly during perioperative preiod, morbidity and mortality can be reduced or avoided. The radiologic findings were poor predict for difficult intubation. The fiberoptic guided awake intubation is a safe alternative to direct laryngoscopic intubation.

Purpose: The purpose of this study was to investigate the education retention effect of endotracheal and laryngeal tube intubation using a manikin study. Methods: The study consisted of measuring intubation time, intubation success rate, and confidence of intubation after education. The evaluation of the education was performed 2 weeks, 4 weeks, and 24 weeks after education and skill tests. The study subjects were 48 paramedic students of third and fourth grade. Results: There was no significant difference in endotracheal intubation time but the time spent performing laryngeal tube intubation significantly increased over time (p<.000). The intubation success rate of endotracheal and laryngeal tube intubation was 100% in the $24^{th}$ week, and there was no significant difference in time spent performing the intubation. The students' confidence in endotracheal (p<.023) and laryngeal tube intubation (p<.001) decreased significantly from the second week to the $24^{th}$ week. Conclusion: This study revealed that it is necessary to spend at least 24 weeks to train students endotracheal and laryngeal intubation to improve the students' confidence in performance of intubation.

Purpose: Difficult organs or locations or inadequate tube intubations can cause complications. There are some cases in which the tube location changes or the tube is removed due to processing inside the organ while installing the stylet or rapid stylet removal. Thus, this study aimed to evaluate and develop an integrated intubation tube with stylet (IITS) for easier intubation of organs in emergency cases and reduce complications caused by the stylet. Methods: This study used a "Laerdal Airway Management Trainer". For stylet intubation, procedure No. 14 of the national practical test protocol was followed, but the removal step was omitted. In this study, each emergency case was intubated with an IITS, in which the stylet was not inserted or removed separately even though it has the function of an organ intubation stylet. Results: The existing classic ET intubation method had a success rate of 100% and had an average intubation time of 21.75 seconds, The developed IITS method was also successful in all cases and had an average intubation time of 15.78 seconds. Conclusion: Application of an IITS is expected to reduce intubation time and decrease inappropriate depth and intubation failure due to stylet removal, therefore improving the efficiency of airway maintenance.

Purpose : This research was designed to provide basic data for advanced pre-hospital airway management by comparing the time to ventilation and success rate for tracheal intubation performed with Macintosh laryngoscope and intubating Laryngeal Mask Airway(ILMA) in a manikin. Methods : All participants were novice users among EMT-Paramedic students and were divided into two groups: (1) the group for Macintosh laryngoscope guided tracheal intubation(MLG-TI) (2) the group for ILMA guided tracheal intubation(ILMA-TI). After an introductory lecture and demonstration, each group made an attempt ten tracheal intubation to compare the ventilation time and success rate for tracheal intubation. Results : 1) There was significant difference in the time to ventilation through MLG-TI, the time to first and second ventilation through ILMA-TI of the 10 attempts. 2) The time to first ventilation through ILMA-TI was significantly shorter than that of ventilation through MLG-TI. 3) There was no significant difference between the time to ventilation through MLG-TI and the time to second ventilation through ILMA-TI. 4) The success rates of ILMA-TI were significantly higher than those of MLG-TI. Conclusion : ILMA-TI can be an alternative method for MLG-TI in advanced pre-hospital airway management.
