When performing an endotracheal intubation or tracheotomy to an unconscious patient in emergent situations, one should consider the possibility of later complication of laryngo-tracheal stenosis which can result in difficulties in decannulation. Laryngo-tracheal stenosis is a bothersome problem developing as a complication of treatment by tracheotomy with a cuffed tube and long-term endotracheal intubation with assisted ventilation. One hundred twenty-three cases of laryngo-tracheal stenosis patients during the four yew period from May 1992 to April 1996 were restrospectively reviewed according to several parameters such as the duration of intubation, site of stenosis, treatment modality and, site of tracheostoma. The present report is an analysis of these materials to search for the possible etiologic factors and its proper preventive methods. It was desirable that the endotracheal intubation should be limited within 20 days at most. Tracheotomy performed by non-otolaryngologists has a tendency to be on a higher level of trachea. Technical precautions should be taken into consideration when doing a tracheotomy. The success rate of decannulation of tracheal T-tube was 78.8% and it required average 11 months.

Damage to the endotracheal tube (ETT) during oral and maxillofacial surgeries is a rare but serious intraoperative complication. Herein, we present a case of a partially damaged ETT that was repaired using Dermabond surgical adhesive (Ethicon, Sommerville, NJ, USA) during a Lefort osteotomy. Dermabond surgical adhesive can be a simple and viable tool to repair partially transected ETTs where ETT exchange carries a high risk of airway loss. Our case adds to one of the several techniques for managing damaged ETT in an intraoperative setting.

In cases of a difficult intubation where numerous intubation methods, including laryngoscopy, have failed, yet oral intubation is still necessary, the method of tube exchange after fiberoptic nasal intubation may be attempted. Fiberoptic nasal intubation allows intubation to be performed relatively easily when the laryngeal view grade is poor. We report a case in which our attempt at oral intubation for total maxillectomy with laryngoscopy and fiberoptic oral intubation had failed due to an unexpected difficult airway; subsequently, we successfully completed the surgery by performing fiberoptic nasal intubation to secure the airway, followed by using a tube exchanger to exchange to an oral endotracheal tube.

The indication for submandibular intubation is the requirement for intraoperative maxillomandibular fixation (MMF) in the presence of injuries that preclude nasotracheal intubation. Thus, We reported 2 cased of endotracheal intubations via submandibular approach that is applicable in patients with skull base fractures for a reliable general anesthesia. Endotracheal intubation via submandibular approach was applied during general anesthetic procedures for open reduction in three patients with Le Fort II, III or nasoorbitoethmoid (NOE) fractures. No complications due to submandibular intubation, such as infection, postoperative scarring, nerve injury, hematoma, bleeding, or orocutaneous fistula, were observed following submandibular intubation. Endotracheal intubation via submandibular approach is effective in patients with skull base fractures. In our method, the tube connector is removed in orotracheal intubation in order to avoiding the tube removal or displacement. The advantages of this method are very simple, safe, and to provide the good operation field.

Objective : Endotracheal tube cuff-pressure[ETCP] increases significantly during anterior cervical spine surgery with neck retraction. Clinically, postoperative hoarseness with sore throat is correlated with vocal cord edema due to longer intubation time and higher ETCP during neck retraction. Methods : Fifty patients of anterior cervical spine surgery were randomized to a control [no adjustment, 25 cases] and a treatment group [ETCP adjusted to 20mmHg, 25 cases]. Patients were blinded to their group assignments. They were questioned about the presence of ischemic symptoms [sore throat, dysphagia, hoarseness] postoperatively at different time points; 4 hours, 24 hours, and 1 week postoperatively. Results : No differences between groups at 4 hours and 1 week postoperatively were demonstrated. At 24 hours, 36% of patients in the treatment group complained of sore throat while 56% of control group patients did [p < 0.05]. Female patients correlated with development of all ischemic discomfort [p < 0.05 : sore throat, hoarseness, dysphagia]. Conclusion : Our results suggest that postoperative ischemic symptom following anterior cervical spine surgery may be associated with the two predictors; increased ETCP during neck retraction and female. The simple procedure of maintaining ETCP to 20mmHg can prevent postoperative tracheal ischemic symptom.

Tracheoesophageal fistula[TEF] is a rare but life-threatening lesion that may occur from ventilation with a cuffed tube. It occurs most frequently when an inlying esophageal tube is also being used-usually for feeding purposes. The mechanism of injury appears to be pressure experted on the tracheal wall by the cuff, which then compresses the "party wall" of the trachea and esophagus against the foreign body that lies in the esophagus. The patient was 32 years old female who had been receiving a treatment of respiratory failure induced by postoperative sepsis with assist ventilator and nasogastric tubal feeding. Sudden attack of abdominal gas distention and massive drainage of gas through N-G tube were developed during assist ventilation in that patient, so we diagnosed as tracheal stenosis with a tracheoesophageal fistula induced by prolonged endotracheal intubation We performed tracheal reconstruction and primary closure of perforated esophagus after weaning ventilator. The postoperative course was uneventiful.eventiful.

With the development of recent IT fusion technology, IT fusion technology of medical equipment has been dramatically development. The need to most basic preferential implementation of emergency is the respiration of the patient, it is necessary to first aid is maintained in emergency patients airway simultaneously. However, to the endotracheal intubation is a procedure to secure the airway, it requires experience and first aid, Inc. good career, very that may lead to sequelae in patients who otherwise have failed to procedures It is a sensitive and important procedure. For these reasons, the success rate of current endotracheal intubation technique is not at a high level and about 50 percent. In an attempt to complement these problems, in this paper, in the process of endotracheal intubation, intubated by inserting an endoscopic camera to Into Activation tube, the streaming is a real-time monitoring and wireless video transmission method using, there is a purpose of enabling the monitoring in smart devices increase the success rate of endotracheal intubation of first aid purchases.

One-lung ventilation (OLV) is the isolation and selective ventilation of one lung field. OLV allows the collapse of lung lobes on the side of the thoracic surgical approach to facilitate observation of intrathoracic structures and to achieve lung immobility. OLV be achieved by endotracheal intubation with double lumen tubes or bronchial blockers. In this study, cardiopulmonary consequences of two-lung ventilation (TLV), OLV and Re-TLV (TLV after OLV) were evaluated in 5 dogs. The dogs were anesthetized with mask induction and maintained with isoflurane in oxygen. Tidal volume and respiratory rates were set to maintain end-tidal $CO_2$ at $40{\pm}2mmHg$ during instrumentation. Following instrumentation, the dogs were placed in right lateral recumbency and induced spontaneously respiration state. Effect of TLV on hemodynamic and pulmonary variables were recorded. Then, the left bronchus was obstructed by endotracheal intubation with double lumen endotracheal tube to achieve OLV state and recording was continued. After OLV, double lumen endotracheal tube was extubated, and standard endotracheal tubes was intubated again. In this study, spontaneous OLV caused significant decrease in $PaO_2$, arterial oxygen saturation, mixed-venous oxygen saturation, and increase in $PaCO_2$. Especially, a significant elevation in $PaCO_2$ and respiratory acidosis were remarkable findings. So spontaneous ventilation in OLV affected gas exchange and hemodynamic function.

In this paper, We propose the purpose the examine the physical factors that influence the success rate during the endotracheal intubation and to provide the basic data for effective intubation success. The subject of this study was 42 students in emergency rescue department who had completed the BLS Health Care-provider and a specialized airway maintenance course dealing with endotracheal intubation and it is a similar experimental study after the non-equivalence single group. For data analysis, SPSS 23.0 Version was used. The study methods were measuring the grip fotce of subjects, the angle of arm during intubation tube, distance from manikin, palm length, etc. The results showed that there was a correlation between the time of successful endotracheal intubation and the physical characteristics. In particular, when performing endotracheal intubation, it was related to the angle of the arm and the execution time of the performer, and the narrower the angle of the arm, the shorter the execution time. The results of this study suggest that successful endotracheal intubation could be implemented if the operator tried to reduce the angle of the arm when performing endotracheal intubation, and through further research on various job groups, identify the possibility of clinical use will be necessary.

Endotracheal intubation is often necessary in the course of animal experiments, especially in craniofacial surgery. However, endotracheal intubation can be a major burden in this context. The authors performed simple and cost-saving method using a 200 µL yellow micropipette tip, and the success of this method was demonstrated by X-ray and autopsy. We used a total of 30 rats. After the rats were fixed with a plaster, the trachea and vocal cords were visualized with the tongue pulled back. Under direct visualization of the vocal cords, a curving micropipette tip was advanced into the trachea. This method can be learned quickly and applied successfully by general experimenters. We successfully intubated all 30 rats without any complications. The success rate of micropipette tip intubation was 100%. This procedure was performed by one experimenter within 2 to 3 minutes after induction of anesthesia. We demonstrated its superiority by X-ray and autopsy. Herein, we describe endotracheal intubation of rats using micropipette tips. To the best of our knowledge, this method is novel and represents the simplest and most efficient means of intubation in rats, providing an alternative to conventional endotracheal intubation.
